Karachi 25 (2): 65-80, 2010 THE CLADISTIC ANALYSIS OF GENERA OF MENOPONIDAE (PHTHIRAPTERA: AMBLYCERA), FOUND IN KARACHI REGION, PAKISTAN SYED ANSER RIZVI AND SAIMA NAZ Department of Zoology, University of Karachi. Karachi, 75270 Pakistan. anserrizvi@hotmail.com; symanaz@hotmail.com (Received for publication May, 2010) ABSTRACT The present work covers the phylogenetic relationship of nine genera of family Menoponidae (Phthiraptera: Amblycera), recorded from Karachi region, Pakistan. These are analyzed cladistically and shown by the cladogram, using their apomorphic characters. The key to the genera of family Menoponidae has also been formulated for the nine genera. This is the first attempt to cladistic analysis of the family Menoponidae from the region. Key words: Phthiraptera, Menoponidae, Cladistic Analysis, Karachi, Pakistan. INTRODUCTION The ‘Mallophaga’ (chewing lice) has been used as orderinal level by many taxonomists (Kim and Ludwig, 1978; 1982; Ferris, 1951) but Weber (1939), Eichler (1941), Königsman (1960) and Haub (1980) had used ‘Phthiraptera’ and include all lice groups as subordinal levels. The suborder Amblycera has been considered the most primitive group amongst all lice (Lyal, 1985; Lakshminarayana, 1986). It consists of seven families viz. Boopiidae Mjöberg, Laemobothriidae Mjöberg, Ricinidae Neumann, Trimenoponidae Harrison, Gyropidae Kellogg, Abrocomophagidae Emerson and Price and Menoponidae Mjöberg (Hopkins and Clay, 1952; Clay, 1970; Richards and Davies, 1977; Marshall, 2002). The family Menoponidae is the largest and oldest amongst all seven families of Amblycera. The taxonomy of the family is relatively stable, but the subfamilial classification within this group has been difficult (Clay, 1970; Marshall, 2003; Johnson and Clayton, 2003). The key to genera of Menoponidae (Clay, 1969) covered only 15 genera with two main groups, Colpocephalum-complex and Menacanthuscomplex. Marshall (2003) covered 35 menoponid genera and provided phylogenetic analysis of morphological characters to support four major groups of Menoponidae. Besides the morphological phylogeny, the molecular phylogenetic analysis has also supported the relationship between menoponid genera (Johnson and Whitting, 2002). Barker (1991) has studied the phylogenetics of amblycera using both morphological and molecular data. Lyal (1985) has studied the phylogeny and classification of the Psocodea with reference to lice (Phthiraptera) in which he gave the apomorphies of Psocodea and both Phthiraptera and Psocoptera are considered to be holophyletic, but lies separately. Mallophagan lice should be valuable evidence on the phylogeny of their hosts; they discussed three factors in the principle of host–parasite co-evolution, discontinuous distribution, secondary infestation and parallel evolution (Chandler, 1916; Clay, 1950). They also have considered the amblycera to be the most primitive lice, their ancestors may start to live as ectoparasitic of warm blooded animals in Triassic Period (225–190 million years ago) and the Ischnoceran lice might be evolved since Cretaceous (135–65 million years ago) or even in the Jurassic Period (Howard, 1950; 1955; Wappler, et. al., 2003). By the phylogenetic and cladistic analysis, it is believed that the chewing lice have evolved from an ancestral stock before the division into Anoplura and the Ischnocera, other that they diverged from those Ischnocera, which are already parasitic on mammals (Kim, et. al., 1973; Marshall, 2002). The intension of the present study was to know Mallophagan fauna from the host birds of Karachi region and to see whether new facts thus obtained could contribute to the existing knowledge of the phylogeny. Unfortunately not a single family has been revised from this region. The morphological characters and characterstats have been derived from Clay (1969) and Marshall (2002). The illustrations have been made by using NIKON Japan Light Microscope with micro-ocular graticule in line graph of 0.5 mm. KEY TO THE GENERA OF FAMILY MENOPONIDAE OF KARACHI REGION 1.

Field experiments were conducted in seven commercial fruit orchards at five various localities. Out of 448 specimens 60.94 % specimens were found in ante-meridian (A.M.) and 39.06% specimens were found in post-meridian (P.M.). Rank abundance values revealed that 9 species in 5 genera of 4 families of order Hymenoptera comprises the diversity of Osmia cornifrons Panzer, Anthophora niveo-cincta (Smith), Anthophora himalayensis Rad., Anthophora crocea Bangham, Bombus tunicatus (Smith), Xylocopa dissimilis Lepel., Xylocopa rufescens Smith, Andrena harrietae Bangham and Andrena anonyma Cam. The calculated values of all diversity indices showed the lowest diversity was found in a monoculture with well weeded orchards whereas the diversity of pollinators was found greater in multiple culture with partially weeded orchards particularly during the successional stage of flowering. This study suggests that diverse habitats with partially weeded orchards and their undisturbed surrounding natural ecosystem could be a better choice for conserving the pollinators. Key words: Diversity, Agro-ecosystem, Fruit orchards, Hymenopterans pollinators. INTRODUCTION Pollination management is a branch of agriculture that seeks to protect and enhance present pollinators and often involves the culture and addition of pollinators in monoculture situations, such as commercial fruit orchards. Plants and their pollinators are often in coevolutionary mutualisms (Free, 1993). Pollination has been recognized to be an important ecological process to maintain and promote biodiversity on earth. More than 16,000 pollinator bee species (Hymenoptera: Apidae) have been described worldwide (Michner, 2000). All postpollination inputs either growth regulators, herbicides, fungicides and insecticides are generally designed not to increase yield, but to conserve losses (Knutson et al., 1990). More seeds develop when large numbers of pollen grains are transferred. Seeds in turn, stimulate surrounding ovary tissue to develop so that, for example, an apple with many seeds will be larger than one with fewer seeds. In this way, good pollination improves both fruit yield and size (Gautier-Hion and Maisels, 1994) Khan M.R and M.R. Khan 2004). Among the pollinators the hymenopterans group play a major role in maintaining the quality of fruits and more better yield (Free, 1993) (Li et al., 2007). It is estimated that bees accomplish more than 80 percent of the insect pollination. Yields of fruit, legumes & vegetable seeds often have been doubled or tripled by providing adequate number of bees for pollination (McGregor, 1976). The wild bees including bumble bees, leaf-cutting bees, alkali bees & carpenter bees are especially adopted for gathering pollens and nectars from flowers (Bohart, 1972). Globally the annual contribution of pollinators to the agricultural crop has been estimated at about US$54 billion (Kenmore and Krell, 1998). In a recent survey (Jasra and Rafi 2008) concluded that 84% of the formers of northern area have no perception about the importance of pollination for their orchards and crops. To prepare an inventory of distributional diversity of Hymenopterous pollinator bees from fruit orchards of Skardu District the study was conducted in spring 2008. MATERIALS AND METHODS Field survey Field surveys were undertaken in five locations in District Skardu of Northern Areas of Pakistan. The A. Hussain et al. 82 detailed survey of commercial fruit orchards in five localities was conducted during early spring of 2008. These orchards and localities were City Park (37.5 acres), PCSIR Orchard ( 12.5 acres) and Agricultural Fruit Orchard Hamid Ghardh (7.5 acres) in Skardu City, Fruit Orchard of Shangrilla (Avg. 35 acres) in Kachura, Agricutural Fruit Orchard of Sermik (Avg. 10 acres) in Sermik, Agricultural Fruit Orchard Mehdiabad (Avg.10 acres) in Kharmang and Hashupi Fruit Orchard (11.5 acres) in Shighar. The clusters of orchard are located in a radius of 20 km. The occurrence and distribution of pollinators varies with the topographic change. The flowering period of major fruit plants of District Skardu is given in (Table 01). At each location roving survey was taken up once in 15 days. In roving survey, the occurrence of pollinators were assessed by taking observations on five randomly selected plants. The hymenopterans pollinators in orchard ecosystem were sampled by using sweep net (30x60x45 cm). Twenty-five sweeps were made diagonally across each canopy and samples were placed in separate plastic sachets. A total of 12 samplings were taken from each orchard. In order to study the proportion of each species within the local community, species diversity was computed based on Shannon-Wiener formula, also been called the Shannon index or Shannon-Wiener index (Humphries et al., 1996). Where, H is the Shannon-Wiener biodiversity index; Pi is the proportion of each species in the sample (relative abundance); log e Pi is the natural log of Pi; and S is the number of species in the pollinators community. The index has been defined in three different ways (Simpson, 1949). Simpson’s index (D). This denotes the probability that two randomly selected individuals in the community belong to the same species. The form of the Simpson’s index used is: S C = ∑ {ni (ni-1) ⁄ N(N-1)} i=1 Where, “ni” is the number of individuals in the” ith” species and “N” is the total number of individual in the sample. The form of the Nakamura’s index used is: S RI = ∑ Ri ⁄ S (M-I) r=i Where “S” is the number of investigated species of insects, “M” is the number of rank of abundance (0, 1, 2, 3… M-I) and “R” is the rank value of “ith” species in the sample. Rank abundance values For studying the species dominance ofpollinators throughout the flowering period, rank abundance values were worked out by taking the sum of individual species found throughout the crop period and ranks were given based on the dominance of Hymenopterous species. Species evenness (J) With a view to understand the measure of how similar the abundance of different species, species evenness was calculated to estimate the equitability component of diversity (Pielou, 1969). H´= C {log10N-1⁄N∑ (log10 nr log10)} Where, H is the Shannon-Wiener biodiversity index; and S is the number of species in the community. Species richness (Ma.) In order to assess how the diversity of the population is distributed or organised among the particular species, this index was calculated (Pielou, 1975). Ma = S-1 log e N Where, S is the total number of species collected; and N is the total number of individuals in all the species. Simpson’s diversity index This accounts for both richness and proportion (per cent) of each species in the local community. RESULTS Occurrence of Hymenopterous bee pollinators in Orchard ecosystems A total of nine species of bee pollinator from five families were during March 2008. A maximum number of predators activity was observed during the full bloom and fruit setting. All the specimens were identified up to species level. Nine (9) species of Hymnopterous pollinator bee in five (5) genera of four (4) families were identified (Table 2). The abundance, richness and evenness (equitability) found in each sampled commercial fruit orchard and total abundance of each species and total abundance of species collected from all sampled commercial fruit orchards are in accordance with (Jasra et al 2000, Jasra and Rafi 2008). Abundance, richness and evenness (equitability) of the Hymenopterous pollinator bees found at peak during the successional flowering time in the orchards of both pome and stone fruits in various Distributional diversity of Hymenopterans pollinator bees localities. Previously Verma and Pertap 1993 also highlighted the impact of mountain pollinators during spring from Himalayan region. Ante-meridian (Before Noon) collection surveys During ante-meridian (A.M.) collection a total of two hundreds and seventy three (273) specimens were collected from all sampled commercial fruit orchards of district Skardu Which is the 60.94% of the total collected specimens in both ante-meridian (A.M.) and post-meridian (P.M.). It shows that Hymenopterous pollinator bees prefer to visit flowers during ante-meridian (A.M.) phase as compared to post-meridian (P.M.) phase of the day time. Post-meridian (After Noon) collection surveys During post-meridian (P.M.) collection a total of one hundred and seventy three specimens (175) were collected from all sampled commercial fruit orchards That is the 39.06% of the total specimens collected in both ante-meridian (A.M.) and postmeridian (P.M.). It indicates that Hymenopterous pollinator bees less prefers to visit flowers during post-meridian (P.M.) phase as compared to antemeridian (A.M.) phase of the day time. Abundance, richness and evenness (equitability) of the Hymenopterous pollinator bees found in all commercial fruit orchards of district Skardu at postmeridian (P.M.) are diagrammatically represented in fig. 3.8.Table 6: The collective rank list along with the list of taxa collected at post-meridian from different commercial fruit orchards of district Skardu During the present study four (4) diversity indices namely; Shannon-Wiener’s diversity index along with its equitability component, Margalef’s index, Simpson’s index and Nakamura and Toshima’s index were used for the calculation of abundance, richness and evenness (equitability). The calculated values and comparison of calculated values of four diversity indices for each sampled commercial fruit orchards of district Skardu are given in table 04. Shannon-Wiener’s diversity index (H') The first index used is the Shannon-Wiener’s diversity index. This index measures the richness and abundance of the calculated species in the sample or sampling area (Shannon-Wiener, 1963).This index is distribution dependent and suffers least from the criticism of validity in biological data (Gray, 1980).The calculated values of this index in different commercial fruit orchards of District Skardu ranged from 2.262 (Agricultural Fruit Orchard Mehdiabad) to 2.945 (PCSIR Fruit Orchard Skardu). Remaining all the commercial fruit orchards yielded the values in between above-mentioned values (2.262-2.945). 83 The calculated values showed that there is no big difference in the calculated values of ShannonWiener’s diversity index. Which means the Hymenopterous pollinator bees are well distributed in all commercial fruit orchards of district Skardu. However, the maximum diversity value calculated from the PCSIR Fruit Orchard Skardu (2.945) and minimum diversity value calculated from the Agricultural Fruit Orchard Mehdiabad (2.262). A). Shannon’s equitability (J') Shannon’s equitability index measures the evenness (equitability) of the calculated species in the sample or sampling area (Shannon, 1963). The calculated values of the Shannon’s equitability index ‘J’ in sampled commercial fruit orchards of District Skardu ranged from 0.875 (Agricultural Fruit Orchard Mehdiabad) to 0.988 (Agricultural Fruit Orchard Hamid Ghardh). Remaining all the sampled fruit orchards yielded the values in between these two (Table 04). Which means the equitabity (evenness) of the Hymenopterous bees from all seven sampled commercial fruit orchards of district Skardu (N..areas) is not significantly different from each other. The calculated values of Shannon-Wiener’s diversity index is very much coinciding with the values of Shannon’s equitability index ‘J’ which means the evenness, richness and abundance of Hymenopterous pollinator bees from all sampled commercial fruit orchards of District Skardu support normal distribution and none of the sampled orchards showed disturbed communities, because the values of the Shannon’s diversity index in perturbed situations are usually more than (Pileou, 1975). Margalef’s index Margalef’s index is used to measure the richness of the species distributed in the sample or sampling area (Margalef, 1969). This index is used frequently in the biological data. The calculated values of the Margalef’s index in seven commercial fruit of district Skardu ranged from 1.298 (Agricultural Fruit Orchard Mehdiabad) to 1.671 (PCSIR Fruit Orchard Skardu). Remaining all the sampled commercial fruit orchards yielded the values in between these two (Table 04). The yielded values of this index from all the sampled commercial fruit orchards indicate that there was no any big difference in the richness of Hymenopterous pollinator bees in these orchards of district Skardu Simpson’s index This index is used to measure the abundance of individual in the sampling unit or sampling area (Simpson, 1949). The value of Simpson (C) index A. Hussain et al. 84 varies from 0 to 1 and if the value tends towards zero it indicates higher diversity. The calculated values of the Simpson’s index from sampled commercial fruit of district Skardu calculated as: 0.965 (City park Skardu), 0.959 (Agricultural Fruit Orchard Hamid Ghardh Skardu) and remaining all sampled commercial fruit orchards 0.999 (Table 4). PCSIR Fruit Orchard Skardu (0.642), and remaining all sampled commercial fruit orchard (0.666). The yielded values of this index indicates that the diversity of City Park Skardu and PCSIR Fruit Orchard Skardu was slightly higher then remaining all sampled commercial fruit orchard of district Skardu (Table 4). The yielded values of this index indicate that the abundance of City Park Skardu and Agricultural Fruit Orchard Hamid Ghardh Skardu were slightly higher than remaining all sampled commercial fruit orchards of district Skardu. The calculated values of all the indices from the entire sampled commercial fruit orchards showed that despite the big difference in the total number of individuals (abundance) there was not a big difference in the richness and evenness of Hymenopterous pollinator bees in district Skardu. Nakamura’s index (RI) The community turnover showed a significant difference in the orchards surrounded by natural ecosystem compare to the clean cultivated orchards in a same geographic situation (Table 5). It in accordance with (Louadi, K and S. Doumandji, 1998) the diversity density of bee pollinators perhaps decreased in mono culture more rapidly. Nakamura and Toshima’s index measures the richness of the species. The calculated value of Nakamura (RI) index ranges from 0-1. If the value tends to zero, the diversity will increase (Nakamura and Toshima, 1999). The calculated values of the Nakamura’s index (RI) from sampled commercial fruit orchards of district Skardu are calculated as: City park Skardu Table 1.

Two families Apidae and Formicidae were identified.This is the first report on the distribution of Order Hymenoptera from mangroves of Pakistan. This study provides the baseline data on the abundance and diversity of insect fauna of mangrove habitats. Key words: Hymenoptera, Mangroves, Abundance. INTRODUCTION Mangrove forests are the most promising feature of our coastal areas. Mangroves were reported to provide habitat and shelter to wide variety of fauna and flora (Wells, 1983). Several studies were carried out on the diversity and abundance of crustacean fauna but very little attention has been paid towards the value of mangroves as a habitat for insect fauna. Insects were reported to play important role in soil fertility and ecosystem health (Van Straalen 1997). They form the important fauna of mangroves and reported to play significant role in detritus formation (Santhakumaran, 1983). Several reports are available from different parts of the world (e.g., Hockey and De Barr, 1988; Raji and Remadevi 2005) but no attention has been paid on the diversity and distribution of mangrove insects in Pakistan. This is the first report on the abundance of Order Hymenoptera associated with mangrove forest along the coast of Karachi. RESULTS Two families Family Apidae and Family Formicidae were identified during the survey. Figure 1 shows the abundance of these two families at Sandspit backwaters and Korangi-Phitti mangrove stands. Higher numbers of insects were observed at Korangi-Phitti mangrove stand. The total number of specimens belonged to Family Formicidae was higher as compare to Family Apidae at both sites (Figure1). The highest numbers of specimens were collected from leaves and stems of mangrove trees and lowest number of specimens was recorded from mangrove tree trunk and pneumatophores (Figure 2). Table 1 shows the abundance of Family Formicidae and Family Apidae on sediments and mangrove parts. Statistical analysis also confirms that mangrove stem, leaves and sediments were the most preferred habitat of Family Formicidae (Figure3). MATERIAL AND METHOD DISCUSSION Regular surveys of mangrove stands at Sandspit backwater (S) and Korangi-Phitti Creek (K) area were carried out during 2004-2006 in South-West Monsoon season to collect representatives of Order Hymenoptera. A total of 30 trees were observed on each site to record the presence of insects. Insects were counted on site and only few representatives were collected randomly by hand picking and by using insect net from mangrove tree trunks, leaves, pneumatophores and sediments. For statistical analysis, the data was standardized, transformed and subjected to Bray-Curtis similarity analysis to visualize similarity in habitat preference. Family Apidae and Family Formicidae of Order Hymenoptera are the common features of studied mangrove forests near Karachi. Studies on mangrove insect fauna revealed that ants were the dominant hymenopteran group (Clay and Anderson, 1996). Similar results were obtained during this study. Species belonging to Family Formicidae are common on the sediments in rhizosphere zone, stem and underside of leaves of the Avicennia marina where they construct nest and obtain their food. At least two species of ants were observed during the survey. Members of Family Apidae were observed on trees which are more than 7 feet in height. Sumera Farooq 88 The higher abundance at Korangi-Phitti mangrove forest may be due to tall trees and thick canopy cover which provides the suitable environment for the insects. They were reported to feed on mangrove leaves and other mangrove associates (Murphy, 1990; Veenakumari and Prashanth, 2009). The study provides the base line data on the occurrence of insects in mangrove forests which is also evident from the signs of herbivory on mangrove leaves. 60 Total abundance % K S 40 20 0 Family Apidae Family Formicidae Figure 1 Comparative abundance of Family Apidae and Family Formicidae at Sandspit (S) and Korangi-Phitti (K) mangrove forests. 6% 8% 8% 30% 48% Tree trunk Leaf Pneumatophores Stems Flowers/ Buds Figure 2 Comparative abundance of insect on different mangrove parts Distribution of order Hymenoptera in Mangrove forests near Karachi, Pakistan Table 1 Abundance of Family Apidae and Family Formicidae on mangrove parts and sediments Habitat Family Apidae Family Formicidae Tree trunk 0 8 Stems 4 26 Leaf 3 45 Flowers/ Buds 8 0 Pneumatophores 0 6 Sediments 0 56 Total 15 141 Figure 3 Habitat preference of Hymenopteran insects calculated from Bray-Curtis similarity resemblance 89 Sumera Farooq 90 REFERENCES CLAY, R.E.

Department of Zoology, University of Karachi, Karachi-Pakistan Baqai Medical University, Toll Plaza, Super Highway, Karachi, Karachi-Pakistan (Received for publication August, 2010) ABSTRACT Herring gulls (Larus argentatus) were collected from an area of Hawks bay, Karachi Coast to study the effects of metals (cadmium, chromium and lead) on glutamic oxaloacetic transaminase (GOT) and glutamic pyruvate transaminase (GPT) inhibition of liver, kidney, and gizzard. High doses (0.0004 gm/0.004 ml) of cadmium chloride, chromium chloride, lead nitrate and low doses (0.0002 gm/0.002 ml) of cadmium chloride, chromium chloride and lead nitrate were injected to birds by insulin syringe. The results showed increased GOT and GPT inhibition in liver, kidney and gizzard of herring gull as a result of high dose of cadmium chloride, chromium chloride and lead nitrate as compared to low doses. Key words: Larus argentatus, Liver, Kidney, Gizzard, Metals, GOT, GPT, Enzyme. INTRODUCTION The contamination of environment by heavy metals is a serious problem they are widely distributed in our environment through geological, metrological, biological, and anthropogenic activities. (Winder et al., 1997). In polluted aquatic environment, water fowls have been found to accumulate high levels of metals in their tissues. (Dieter et al., 1976). Environmental pollutants are potential harmful to each bird species regardless of the age of the individual. Birds are not only the most threatened groups by chemical agents, but also very sensitive indicators of the pollution in their environment. (Peczely, 1987; Hoffman,1990; Vodela et al., 1997). Heavy metals produce negative effects on physiological and biochemical functions of test organisms. (Khandelwal et al., 1991 and Uyanik et al., 2001). Liver and kidney are the primary organs involved in heavy metal excretion and where accumulation of heavy metal is more. (Devy and Khan, 2006). In present study, herring gulls (Larus argentatus) were selected to observe the effects of cadmium, chromium, and lead on the transaminase enzymes like glutamic oxaloacetic transaminase (GOT) and glutamic pyruvate transaminase (GPT) of body tissues. MATERIALS AND METHODS Alive herring gulls (Larus argentatus) were caught from an area of Hawks bay, Karachi. They were kept in the controlled condition for 15 days in three groups (Group-A, Group-B, and Group-C) before experimental work. After 15 days, three stock solutions were prepared by dissolving 1 gm of each salt (cadmium chloride, chromium chloride, and lead nitrate) in 100 ml distilled water. High dose (0.0004gm/0.004 ml) and low dose (0.0002gm/0.002ml) were injected to each bird in Group-A and Group-B, respectively by insulin syringe. While Group-C was quarantined in laboratories conditions as Control. After eight hours, birds were sacrificed and dissection was made to get liver, kidney, and gizzard to estimate GOT and GPT. 0.5 gm of each tissue was taken from each organ. Each tissue was crushed with mortar and pistle. Then they were homogenized in Teflon Pyrex tissue grinder for 5 minutes at 1000 rpm. The homogenates were centrifuged at 3500 for 30 minutes in Labofuge 200 Ind Rotar (Heraeus). Supernatants were kept in separate tubes. During experimental work homogenates, supernatants, and reaction mixtures were kept in ice box at 10 ºC. Enzyme kit of Cromatest Lot #13032 of GOT and Lot # 12853 of GPT was used. A principle, Procedures and calculation method was used according the standardized method described by IFCC., (2002) to estimate GOT and GPT. The mean of result was calculated to obtain the average change in absorbance per minutes (ΔA /min) by using the formula: u/l = ΔA /min x 3333 (37 ºC) RESULTS The effect of low and high dose of cadmium chloride, chromium chloride, and lead nitrate on Glutamic oxaloacetic transaminase (GOT) and glutamic pyruvate transaminase (GPT) inhibition in liver of Larus argentatus. Control samples showed 4.166 u/l and 6.666 u/l GOT and GPT in liver, respectively (Fig1a and 1b). Whereas GOT levels were 703.263 u/l, 273.306 u/l, 396.627 u/l in liver as a result of high dose of lead nitrate, chromium chloride, and cadmium chloride, respectively and 92 Effects of Metals on Enzyme Inhibition in Marine Bird, the Herring Gull 29.997u/l, 189.981 u/l, 336.633 u/l in liver as a result of low dose of lead nitrate, chromium chloride, and cadmium chloride, respectively(Fig 1a). GPT levels were found 370.796 ug/l, 700.763 u/l, 249.975 u/l as result of high dose of lead nitrate, chromium chloride, and cadmium chloride, respectively and 246.642 u/l, 105.822 u/l, 78.325 u/l as a result of low dose of lead nitrate, chromium chloride, and cadmium chloride, respectively in liver of Larus argentatus (Fig 1b). Fig 2a and Fig 2b indicates the levels of GOT and GPT in gizzard of Larus argentatus, respectively. In control group, GOT and GPT levels were recorded 3.333ul/l and 4.166 u/l in gizzard, respectively. While as a result of high dose of lead nitrate, chromium chloride, and cadmium chloride, GOT in gizzard of Larus argentatus was 199.98 u/l, 19.998 u/l, 309.969 u/l and 6.666 u/l, 10.832 u/l, 96.657 u/l, respectively (Fig 2a). In Fig 2b, GPT levels were 738.259 u/l, 333.466 u/l, 164.983 u/l as a result of high dose of lead nitrate, chromium chloride, and cadmium chloride and 234.143 u/l, 149.985 u/l, 102.489 u/l as a result of low dose of lead nitrate, chromium chloride, and cadmium chloride, respectively. Fig 3a shows the levels of GOT in kidney of Larus argentatus. Control samples showed 9.999 u/l and 2.499 u/l GOT and GPT in kidney of Larus argentatus,respectively (Fig 3a and Fig 3b). As a result of high and low dose of lead nitrate, chromium chloride, cadmium chloride, GOT levels were found 25.830 u/l, 593.274 u/l, 406.626 u/l and 20.831 u/l, 399.96 u/l, 383.295 u/l, respectively (Fig 3a). Whereas Fig 3b indicates the levels of GPT in kidney of Larus argentatus. Levels of GPT were found 693.264 u/l, 207.479 u/l, 155.817 u/l as a result of high dose of lead nitrate, chromium chloride, cadmium chloride and 100.823 u/l, 129.153 u/l, 17.498 u/l in kidney as a result of low dose of lead nitrate, chromium chloride, and cadmium chloride, respectively as shown in Fig. 3b. DISCUSSION In present study, GOT level in Liver (4.166 u/l), gizzard (3.333 u/l), kidney (9.999 u/l) and GPT level in liver (6.666 u/l), gizzard (4.166 u/l), kidney (2.499 u/l) was found in control group. These levels were low as compare to high and low dose samples. The highest GOT (703.263 u/l) and GPT (738.259 u/l) was found in liver and gizzard of Larus argentatus, respectively as a result high dose of lead nitrate. This is due to certain tissue cells contain characteristic enzymes which enter the blood only when the cells to which they are confined are damaged or destroyed. Cain et al., (1983) found significant decreases in packed cell volume, and hemoglobin concentration and a significant increase in serum GPT in mallard duckling (Anas platyrhynchos) fed 20 ppm cadmium. Meenakshi et al., (1989) observed decreased enzyme activity in the cadmium chloride treated animals due to the decreased translocation of the enzyme areas epithelial membrane. Reduction in activity also reflected loss of brush border membrane besides inactivation of the enzyme. Abu-Sinna et al., (1991) studied the effect of lead nitrate in 3 day incubated chicken eggs and lead nitrate increased the activity of all investigated enzymes (Alkaline and acid phosphatase, GOT,GPT). In present work, GOT and GPT activities were increased by high dose of lead nitrate. Shakoori et al., (1992) investigated biochemical changes following lead acetate exposure in liver and muscles of fresh water fish (Cirrhina mrigala). Within one week of treatment, AP,GPT, lactate dehydrogenase (LDH) and amylase activities were increased, respectively. (61%, 23%, 48%, 84% after dose of 0.25 mg/ml) and during 1st week of metal exposure (1.0 mg/ml), GPT activity was decreased (35%). Bag et al., (1999) found the toxic effects of heavy metal contaminants from sludge supplemented diets on male wistar rats. The sludge was found to be contaminated with Zn, Ni, Pb, Co, Cr, and Cd. The toxic effects of sludge supplemented diets were noted in serum, liver, muscles, and brain. Levels of liver GPT activities were found higher. Benkoel et al., (2000) observed the hepatotoxic effects of heavy metals (Cd, Hg, Cu) on enzyme histochemical activities of yellow legged gull (Larus cachinnans michahellis). Robert., (2001) observed that decreased hepatocellular production inhibition results in decreased of GOT and GPT activity. In present investigation, the lowest levels of GOT (29.997 U/L) and GPT (78.325 U/L) were found in liver as a result of low dose of lead nitrate and cadmium chloride, respectively. Uyanik et al., (2001) described the effects of Cd and Zn in the organs of broiler chicks. These compounds reduced the weight and damages were observed in liver, kidney, and bursa of fabricius. GPT activity lowered and other enzyme activities were slightly increased. Present findings showed the decreased GPT activity as a result of low dose of cadmium chloride, chromium chloride and lead nitrate in liver, kidney, and gizzard compared to high doses. Erdogan et al., (2005) studied the effects of ascorbic acid on Cd-induced oxidative stress and performance of broilers. Cd was given via the drinking water at a concentration of 25 mg/L for 6 weeks. Cd decreased body weight and feed efficiency but liver function enzymes, AST, ALT, LDH, and gamma glutamyl transferase (GGT) activities were not changed by cadmium. Whereas in present study, changes were noted in the levels of GOT and GPT activity in liver, kidney, and Gizzard as compare to control group. Devy and Khan (2006) studied the effects of cadmium chloride in liver and kidney of male and female wistar rats at three different dose levels: 0.5, 1.0, and 2.0 mg/kg., given intraperitoneally daily for 15 days. There is an increase of GOT in the kidney tissues and decreased in liver tissues of both male and female rats. Whereas, GPT level was desreased Raza N. et al. in liver and increased in kidney in both male and female rats. In present study, there was an increase of GOT in kidney as compare to liver and levels of GPT were increased in liver as compare to kidney. Jadhav et al., (2007) studied the effects of subchronic exposure via drinking water to a mixture of eight water-contaminating metals (Arsenic, cadmium, lead, mercury, chromium, manganese, 93 iron, and nickel) on male wistar rats. After 60 days of exposure, increased activities of GOT and alkaline phosphatase were found but GPT activity was not affected. Whereas in present findings, both GOT and GPT activities were affected by low and high dose of cadmium chloride, chromium chloride, and lead nitrate compared to control group.

(Received for publication October, 2010) ABSTRACT The new species of Tanymecus pakistanensis is described with reference to various parts of the body including male genitalia and compared with its closest allies. Key Words: Coleoptera, Curculionidae, Tynymecus, New Species, Sindh, Pakistan. INTRODUCTION MATERIALS AND METHODS The work on weevil genus Tanymecus Germar carried out from Indian subcontinent by Marshall, 1916 and Supare et al, 1990. Marshall (1916) described 43 species of Tanymecus, later on Supare et al (1990) revised these species and described 44 species including two new genera Burmanicus and Krauseus and one new species T. bhagwani whereas Tanymecus simplex Marshall only confined in Pakistan. They described all species with detailed account of their morphology, male and female genitalia and economic importance with their host plants. Anderson (2002) described classification of Nearctic Curculionidae and its subfamilies and genera with their key. Ramamurthy and Ayri (2010) revised the Tanymecini endemic genus Indomias with 25 species described with key and illustrations of various parts of the body including male and female genitalia. The present taxon was collected from Tandojam, Sindh by hand picking method. The measurement and illustrations were made by using ocular grid microscope. For the study of male genitalia, the abdomen was excised at the base and boiled in 10% KOH solution for about 10 minutes. It was then washed in tap water. The aedeagus was dissected out and examined under glycerin. After studying the male genitalia, the material was placed in microvials with a drop of glycerin and pinned with the specimens for Natural History Museum, University of Karachi (NHMUK). In Pakistan, a virtually work has been carried out by Aslam, 1966a, 1966b but only three genera Strophosomoides Aslam, Achlaenomus Waterhouse and Hyperomias Marshall with their species related to Tanymecini described (Aslam,1966, 1966). Rizvi et al (2003) and Zubair et al (2006) described two new species of Tanymecus from Pakistan with reference to their male genitalia. There could be more species of the genus Tanymecus in Pakistan and it could increase the listing of genus Tanymecus from Indian subcontinent. RESULTS Tanymecus pakistanensis sp.nov.

Taxonomic structures not discussed and not illustrated before are described and illustrated as additional information to facilitate zoologists and veterinarians in correct identification of female and male of this louse. A key is erected to Anopluran families and genera highlighting the relationships of included families. It is hoped that this paper will provide an anatomical base for future morphological studies. Key words: Re-description, Pediculus humanus corporis, Pediculidae, Balochistan, Pakistan. INTRODUCTION Human lice are obligate ectoparasites. They suck the blood of humans. They have specially designed mouth-parts for piercing the skin of humans and retrieving the blood that is present (Chew, et al., 2000). Head lice cause greatest nuisance, and have been experimentally infected with Rickettsia prowazeki de Rocha-Lima. Head and pubic lice both have never been implicated directly in active disease transmission (Roy and Brown, 1954). In Pakistan, so far no serious efforts have been exercised to study morpho-taxonomy of human body lice, except a short note on morphological characters of Pediculus humanis capitis Linnaeus, 1758 (Kakarsulemankhel, 2007). Owing to their medical significance and to fill the gap of knowledge, Pediculs humanus humanus (Linn.) is re-described in detail to help zoologists in correct identification of this louse. MATERIALS AND METHODS Human body lice were collected from the clothes of Coal mine laborers 2 working at Mach, Balochistan, Pakistan during May, 22, 2009. Samples were transferred to vials containing 70% alcohol for laboratory examination. Lice were placed in Phenol for 3-4 days at room temperature. Head region and genitalia of lice were removed from the body for detail examination and placed in 20% KOH for half an hour. De-hydrated in graded series of alcohols and cleared in xylene and mounted permanently in Canada Balsam. Structures were observed and measured under 40X and 100X magnifications at Binocular microscope (CH-2, Olympus, Japan). Diagrams were made with a Camera Lucida. Measurements were taken in millimeters (mm). All the diagrams are to the given scales. Prepared permanent slides were deposited with the Author’s collection of Lice, BUITEMS, Air Port Road, Quetta. RESULTS The genus Pediculus is defined on the basis of following characters: Head with eyes, 5-segmented antenna, thorax with single pair of spiracles in between the I and II pair of legs, abdomen with seven obvious segments, first six abdominal segments bear spiracles, pleural plates developed. The genus Pediculus includes two sub species namely humanus corporis and humanus capitis. Corporis subspecies can easily be recognized on the basis of its slender and comparatively larger bodies, narrow thorax than abdomen, abdomen with marked lateral notches antennae are longer whereas humanus corporis can easily be distinguished on basis of characters: smaller body, shorter and thicker antennae, lateral abdominal notches less distinct.

External Anatomy: Dorso-ventrally flattened body, Head, thorax, and abdomen clearly separated, head prognathus with the mouth opening terminal. Mouth parts (Fig.A1-A10): Highly specialized mouthparts are not visible externally, strictly 3 slender stylets present in a ventral pouch and this constitute a set of fine cutting apparatus which can be protruded during action to puncture the host’s skin and blood is sucked in to the prestomum (true mouth, haustellum) (Fig.A1) by a muscular cibarial pump (Fig.A2), prestomum is furnished with fine teeth (Fig.A3), if not in use stylets are retracted in to stylet sac (Fig.A4) usually lies under the pharynx (Fig.A5), the dorsal stylet (Fig.A6) represent maxillae, the ventral stylet (Fig.A7) stronger than others bears teeth at tip (Fig.A8) and used for piercing the skin of the host (Ferris, 1951), represent the terminal part of labium, the median stylet (Fig.A9) represent hypostome (true mouth) (haustellum), stylets are forked at their proximal ends (Fig. A10). Palps: Absent. Eyes: Definite eyes externally on lateral lobes. with lenses present Antenna: 5 segmented, combined length of I and II segment larger than length of III-V segment. Legs: 3 pairs: All legs not similar in shape and size but first two pairs comparatively shorter and attached at anterior thoracic region while the III pair comparatively larger borne at anterior abdominal segment, claws strong, tibia short bearing spines and hairs, there is only single tarsal segment. Spiracle: 1 pair of meso-thoracic spiracles present in between I and II pair of legs on the thorax, six pairs of spiracles present at sides of III-VIII abdominal segments. Thorax: Wider than head but less wider than abdomen, three thoracic segments fused, sclerotized sternal plate on the thorax. Abdomen (Fig.A11): 9-segemented, I and II segments fused and always concealed, III–IX quite obvious, abdomen poorly sclerotized, pleural plates present (Fig.A11) at both sides of abdominal segments III–VIII, anus lies below the gonopods in the last abdominal segments. Genitalia (Fig. A12-A15): In the female the last segment of the abdomen (IX segment) bifurcates in to two larger posterior lobes (Fig.A12), female can easily be distinguished by having a strong chitinised triangular structure (0.3 long, 0.15 broad) known as genital plate (Fig.A13) and 2 pairs of lateral gonopods (Fig.A14), vaginal orifice (Fig.A15) located in the middle of both the gonopods. Chaetotaxy (Fig. A16): Head: Most apical anterior part bear 1 long seta and 2-3 short setae at each sides, sides of the head also bear short setae. Antennae and Legs: All segments bear lateral as well as dorsal setae. Abdomen: Each abdominal segment has strictly 2 zig zag rows of abdominal setae, each row with 10 or above setae dorsally as well as ventrally projecting posteriorly. A curved row of about 10 strong spines present in the VII abdominal segments above the tri-angular chitinized structure. The apical end of the two hind lateral parts of the IX segment bear some 5-7 small setae (Fig.A16). Male: A little shorter in size than ♀, antennae same as in ♀, abdomen comparatively little shorter as in ♀. Legs (Fig. B1-B2): The anterior leg of the ♂ much stouter and provided with a larger tibial thumb (Fig.B1) and a larger tarsal claw (Fig.B2) for grasping the posterior leg of the female during copulation. Abdomen (Fig. B3): Hind end of abdomen (IX segment) almost rounded (Fig.B3). Genitalia (Fig. B4-B9): It starts from abdominal segments VII–IV with two chitinized rod like structure (0.64-0.66 long) (Figs.B4 (X100) & B5 (X400) running from segment VII to IX, anteriorly the gap between rods more (0.18) which gradually narrows Re-description of Pediculus humanus corporis Linnaeus, 1758 (Anoplura) till the terminal end, also known as vaginal dilator which is hooked deep into the vagina, casually this structure projecting from the sex opening of male (Figs.B6 (X100) & Fig.B7 (X400), apical-distal part of the aedeagus (Fig.B8 (X400) is chitinized but its basal-proximal part is in the form of a thin walled chitinous sac (Fig.B9 (X400). Chaetotaxy (B10): Almost similar as in ♀ except the lateral side of hind end of last abdominal segment bear a row of some 10-14 long and medium sized setae projecting outwards (Fig.B10 (X400). Material examined: 11 ♀, 9 ♂, Balochistan, May, 2009. Distribution: Worldwide. Comparative note: Pediculus group is entirely isolated with apomorphies of slender bodies, thorax little broader than abdomen, 7-segmented abdomen, stouter legs, and more hairy body. Within this group, corporis (body lice) and capitis (head lice) both share some characters except shorter antennae in corporis. However, Phthirus group is quite distinct from the two species of human lice and can be easily differentiated for its autapomorphies of broad short body, long, clawed legs, very broad thorax with all segments fused and comparatively shorter abdomen with first three segments fused, last four abdominal segments bearing wart-like structures on the sides and last pair particularly large. The capitis may be recognized on the basis of indentations between successive abdominal segments which are more clearly marked than they are in corporis. Legs of the head lice are shorter than those of body lice. Table 1. Comparison Pediculus corporis L. (present study) with Pediculus capitis L.

Results of the present study have been compared with humanus capitis L. (author’s unpublished data). Corporis sub species was observed to be little larger than its closely related sub species Capitis. Body lice may pose the most serious health threat in many countries. These lice are known vectors of epidemic or louse borne typhus caused by Rickettsia prowazeki, trench fever, caused by Rochalimaea quintana (Schmincke) Krieg (also known as Rickettsia quintana) and louse–borne relapsing fever, caused by Borrellia recurrentis (Lebert) (P.A.H.O., 1973; Weems and Fasulo, 2007).

(Received for publication November, 2010) ABSTRACT Recent trend for the control of insect pests has been towards the use of substances of plant origin. Toxicity and residual effects of yellow-berried nightshade, Solanum surrattense Burm. leaves extract were determined against adults of red flour beetle, Tribolium castaneum (Herbst) by contact method during a period of 8-days under laboratory condition. The lowest mortality 15% was observed at the minimum dose 2.4 μl/cm2 and the highest 100% was observed at the maximum 16.8 μl/cm2 after 24 h. The LD50 of S. surrattense was found 8.02 μl/cm2. Finally, residual effects of the same plant extract was st 2 observed, during 1 day, mortality, the lowest was 49.4% at minimum 2.4 μl/cm dose and the highest 2 th mortality was 91.6% at maximum 12.0 μl/cm dose. During 7 day, mortality, the lowest was 5.0% at 2.4 2 2 th μl/cm and the highest was 60.5% at 12.0 μl/cm . During 8 day, mortality, the lowest was 0.4 % at 2.4 2 2 μl/cm and the highest was 16.0% at 12.0 μl/cm . The mortality percentage of T. castaneum was increased with the increase of doses and time-period in both toxicity and residual effects. It is concluded that leaves extract of S. surrattense could be useful for managing populations of T. castaneum. Key words: Contact method, leaves extract, residual effect, Solanum surrattense, Tribolium castaneum, toxicity. INTRODUCTION Red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenberionidae) is one of the most common pest of stored grains and their products (Ali et al., 2009). The damage caused by this insect to various stored and food commodities like grains, flours and dried fruits is recoded to be 15-20% which is capable of incurring losses worth million rupees every year in developing countries (Siddiqui et al., 2006). In Pakistan, T. castaneum is commonly found in association with other pests in storage. It has great effect on the economy of Pakistan which is always under estimated (Tripathi et al.; 2001). Kouninki et al. (2007) observed insect infestation, mainly by T. castaneum in gunny bags of stored sorghum and reported that loss due to the infestation was 3.6% and 25.7%, respectively after six and nine months of storage. Annual post-harvest losses resulting from insect damages, microbial deterioration and others factors are estimated to be 10-25% of worldwide production (Matthews, 1993). In Pakistan, the losses caused by insect pests to crops and stored materials etc, alone were 23.2% worth of Rs. 140 million annually. The losses are approximately double the world average (10.9%) and also higher than that of Asia. They could be compared with U.S.A. 9.4, Australia 7.0, South America 10.0, Europe 5.1, Africa 13.0, U.S.S.R. 10.5, China 11.5 and Asia 20.7% (Ali et al., 2009). In Karachi, T. castaneum is found damaging more wheat in Dockyard areas probably due to damp climate which, soften the hard pericarp of wheat grain. Control of these pests is prime important in order to meet the demands of increasing population. The outbreaks of these pests could be avoided either by protect ion and/or by treatment of the stored commodities with chemicals. Protection includes all the prophylactic measures and disinfection of stores, bins, bags and grains by using BHC, Baythion, Diazinon, Gardona, Malathion etc. These chemicals are applied before the grains are being stored in order to eliminate chances of future infestation of the pests (Naqvi and Perveen, 1991). Treatment of grains, on the other hand, has to be carried out with fumigants when infestation of the pests appears during the storage (Mahuliker and Chavan, 2007). Various companies recommended HCN, acrylonitrile, chloropicrin, ethylene dibromide, methyl bromide, ethylene oxide, ethylene dichloride, carbon tetrachloride, petrol and DDVP etc for Perveen F. et al. 108 fumigation against insect pests of stored products (Anonymous, 1986; Naqvi and Perveen, 1993). Fumigation has been an important method for controlling insects and mites in stored products. There is a lot of work on the development of special techniques, mostly to obtain better distribution of fumigates in the product by improved stirring, forced circulation or by using vacuum fumigation. Major factors in the development of these new techniques have been, for example, proof of the great penetrative power of methyl bromide, the relative safety in the use of brominated aliphatic hydrocarbons; the increase use of gas concentration at intervals of time in different parts of the products to investigate the behavior of the fumigant and to bring forward reasons for success or failure in practice (Rehman et al., 2001). In the view of the above fact the aim of present study was to find a better and economical control agent of T. castaneum. For this purpose, the toxicity and residual effects of leaves extract of S. surrattense was tested against the adults of T. castaneum. MATERIALS AND METHODS The present research work was carried out in the Molecular Biology Laboratory, Department of Zoology, Kohat University of Science and Technology, Kohat, Pakistan. Insect rearing Experiments were conducted with adults of T. castaneum taken from a stock that was established from 25 pairs of adults obtained from local godowns of grains, Kohat, Pakistan and were reared in (6 cm dm × 13 cm high) plastic bottles containing 250 gm wheat flour with bran in the laboratory under controlled conditions. The rearing temperature was maintained at 25±1 °C, with a LD 16:8 h photoperiod and 50–60% r.h. Therefore, the insects of uniform age and size were available throughout the year. The experiments were started when pure culture (after 4 generations) and sufficient population was available. Preparation of plant extract Extracts were prepared from the leaves of S. surrattense collected from the KUST Campus. Leaves (250g) were rinsed with distilled water, dried and ground to a solution with an electrical blender and added ethanol and distilled water (1:1). Then it was concentrated on rotary evaporator under reduced pressure for 2 h, dark green gummy residue (30 g) was obtained. The residue was dissolved in distilled water on the basis of increasing polarity to obtain ethanolic extract and doses were made accordingly. They were tested for toxicity and residual effects against T. castaneum. Toxicity Toxicity was determined according to procedure used by Naqvi and Perveen (1993) to find out the effective range of S. surrattense leaves extract. The experiments were conducted on the adults of T. castaneum by contact method/ filter feeding mechanism. Extract was applied on the filter paper (90 mm dm) in petri dishes at different concentrations of 0.5ml 1.0ml 1.5ml 2.0ml 2.5ml 3.0ml & 3.5ml. These concentrations were selected after preliminary trials. Therefore, the amounts of insecticide applied on filter paper were 2.36, 4.72, 7.08, 9.44, 11.80, 14.16 & 16.52 respectively. The petri dishes were then air dried for few min and five pairs of adult were released to each petri dish. The untreated and control (2 ml of solution containing ethanol and distilled water: 2:1) batches were prepared to observe environmental and solvent effects, respectively. These batches were kept under the same environmental conditions as those used for the rearing stock culture. They were examined after 24 h and mortality was recorded. If the mortality was more than 10% in untreated and control then experiments were discarded. Each experiment was set in three replicates and average values of fifteen experiments were analyzed. Residual effects The residual effects of S. surrattense leaves extract on adults of T. castaneum were determined by using the same method and doses as used for Toxicity. After drying the petri dishes five pairs of adult were released to each petri dish daily up to 8 d, without changing the filter paper and mortality readings were taken after every 24 h. Statistical analysis The volume of S. surrattense leaves extract was calculated using the Charles’s Equation: C1V1=C2V2; where C1: concentration of the solution; V1: volume of the solution; C2: concentration to be made; V2: volume of the required concentration. For Toxicity, the mortality % was calculated using Abbott's formula: % mortality = (% test mortality –% control mortality)/ 100 –control mortality ×100. For Residual effect, the standard deviation was calculated by using the following formula: SD=√ Σx2–n (x )2/n-1; where S.D.: standard deviation; x2: notation for variation of variable x; n: total number of observation; X: average of variable x. The LD50 was calculated through probit analysis. RESULTS Toxicity The toxicity of S. surrattense leaves extract against adults of T. castaneum was measured by contact method. Five doses were used to find the most toxic dose among them. Mortality was increased with the increase in doses as evident from Fig. 1 and Table 1. The lowest mortality (15%) was Toxicity and residual effect of Solanum surrattense against Tribolium castaneum observed at the minimum dose 2.4 μl/cm2 and the highest (100%) was observed at the maximum dose 12.8 μl/cm2 after 24 h. The LD50 of S. surrattense was found to be 8.02 μl/cm2 as shown in Fig. 1. Residual effects For determination of the residual effects, five doses of S. surrattense leaves extract were used against adults of T. castaneum by contact method. During 1st day residual effects of 2.4, 4.8, 7.2, 9.6 and 12.0 µl/cm2 of S. surrattense leaves extract showed 49.4, 49.4, 63.5, 80.3 & 91.6% mortality of adults of T. castaneum, respectively. On 2nd day, the same doses showed 20, 30, 50, 65 and 80% mortality, respectively. On 3rd day, mortality was 25.3, 40.7, 48.5, 71.7 and 89.7%, at the same doses, respectively. On 4th day, mortality was 15.0, 37.5, 42.5, 7.5 and 79.5%, respectively. On 5th day, mortality was 12.5, 25.0, 35.0, 62.5 and 70.7%, respectively. On 6th day, mortality was 5.0, 25.0, 35.0, 62.5 and 9.5%, respectively. On 7th day, mortality was 5.0, 22.5, 35.0, 55.0 and 60.5%, respectively. On 8th day, mortality was 0.4, 0.6, 5.0, 14.4 and 16.0%, respectively (Fig. 2). DISCUSSION The natural plant pesticides may be used to control insect pests due to their less harmful effects to the non-target-species and environment as compared to synthetic pesticides. Therefore, the toxicity and residual effects of S. surrattense leaves extract were analyzed against adults of T. castaneum. The LD50 of S. surrattense was 8.02 μl/cm2. This indicates that plant has significant toxicity against T. castaneum. No similar work has been reported on S. surrattense so far. However, Rashid et al. (2009) reported that crude dichloromethane extract of Salvia cabulica exhibited significant (80%) insecticidal activity at the highest dose against T. castaneum. In present studies, the S. surrattense leaves extract exhibited a significant (91.6%) insecticidal activity by the highest dose 12.0 μl/cm2 against T. castaneum after 24 h. The difference in mortality was due to different plant species or solvent used. Khanam et al. (1995) reported the effect of Thevetia neriifolia leaves extract on T. confusum adults where acetone extract was found to be the most effective toxicant followed by ethyl acetate, petroleum ether and methanol extracts. The present results (Table 1) showed that S. surrattense leaves extract also extended its effect on the adults of T. castaneum. Two studies are almost in agreement with each other as far as toxicity is concerned, however, different species as well as different solvents were used. 109 Azmi & Naqvi (1998) showed contact toxicities of neem extract RB-a and coopex using impregnated paper, the activity was found to be 34% with a 1257. 1 µg/cm2 dose of RB-a while 24, 28, 32 and 50% mortalities were observed by applying 1.1, 2..5, 3.7 and 6.2 µg/cm2 coopex against Sitophilus oryzae, respectively. In present studies, it is reported that 48, 49, 63, 80 and 92 % mortalities were observed when applied 2.4, 4.8, 7.2, 9.6 & 12.0 μl/cm2 doses of S. surrattense leaves extract using filter feeding mechanism against adults of T. castaneum, respectively. The differences were due to use of difference in procedure, different plant or insect species used. Jbilou et al. (2006) reported significant insecticidal activity against T. castaneum larvae by crude methanol extract of Peganum harmala, Aristolochia baetica, Ajuga iva and Raphanus raphanistrum having mortality count 58, 34, 31 and 26%, respectively, as extracts were mixed with the diet at concentration of 10%. In present research, S. surrattense leaves extract showed 15, 25, 40, 55, 75, 85 & 100% mortality against adults of T. castaneum by filter feeding mechanism. These variations were due to different plant species used in two experiments or difference in procedure used. Ogunleye and Adefemi (2007) tested dust and methanol extracts of Garcinia kolae against Callosobruchus maculatus and Sitophilus zeamais. They found the dust had no significant effect on the two insects while the methanol extracts had rapid lethal effects on both C. maculatus and S. zeamais. The mortality of C. maculatus by the lowest concentration of methanol extracts ranged from 95~100% whereas in S. zeamais, the mortality ranged from 87.5~100 and 70~100% in concentrations of 3 ml methanol was added to 1 g extract and 5 ml methanol was added to 1 g extract, respectively, from 24 to 48 h. The present result showed that the S. surrattense leaves extract had rapid lethal effects on T. castaneum. The mortality of T. castaneum was ranged from 48, 49, 63, 80 and 92% by the lower to higher concentration of leaves extracts. The differences were due to different plant and insect specie used or due to difference in concentration of extract in two studies. The results of residual effects showed that leaves extract of S. surrattense has significant results during first day and shows 49.4, 49.4, 63.5, 80.3 and 91.6 % mortality with the doses used 2.4, 4.8, 7.2, 9.6 and 12.0 μl/cm2. Naqvi and Perveen (1991) investigated residual effect of Nerium indicum crude extract as compared with coopex against adults of T. castaneum and found that both the samples did not have prolonged residual effect by method used. The present results showed significant residual effects (Table 2) were different from found by Naqvi and Perveen. This may 110 Perveen F. et al. be due to low toxicity of the leave extract and difference in the plant species. Ahmed et al. (2004) assessed five organophosphorus compounds, five synthetic pyrethroids and three insect growth regulators against T. castaneum in peanuts stored. Activity against adults and progeny was assessed separately. Of the insecticides tested, chlorpyrifosmethyl, methacrifos and deltamethrin applied completely prevented the development of progeny. In the present research, S. surrattense leaves extract gave high mortality against adult of T. castaneum. Differences in both results were due to different insecticides used. Mondal and Khalequzzaman (2006) tested contact and fumigant toxicity of the three essential oils, viz., cardamom (Elletaria cardamomum Maton), Cinnamon (Cinnamomum aromaticum Nees), and Clove (Syzygium aromaticum (L.) against T. castaneum larvae and adults. The results revealed that cardamom oil was generally a more effective contact poison or fumigant against the adults of T. castaneum. In present studies, different doses of S. surrattense leave extract were tested against T. castaneum and n-butanol fraction was found to be most toxic than others. A direct comparison of the potency of contact toxicities of the essential oils could not be made because different experimental methods were employed. Arthur (2008) applied insecticidal pyrrole chlorfenapyr to adults of T. castaneum and T. confusum and placed them on 3 different surfaces (concrete, tile and plywood) for 2 and 4 h, removed, and held without food for 7 d post-exposure. All beetles survived the initial exposures, but survival of both species decreased during the 7 d holding period, with T. confusum being the more susceptible species. Efficacy also varies depending on the surface substrate. In the present research, different doses of S. surrattense leaves extract was checked for their efficacies against adults of T. castaneum in petri dishes and it was found that mortality was increased with the increase of doses and it decreased gradually during increased of days. The difference here may be due to fact that in first studies synthetic pesticide was used while in present work plant extract was applied. Epidi and Odili (2009) tested the efficacy of powders of plant parts from Telferia occidentalis (fluted pumpkin), Zingiber officinale (ginger), Vitex grandifolia (Vitex) and Dracaena arborea (dragon tree) using completely randomized design (CRD) against T. castaneum in groundnut and found that V. grandifolia and D. arborea both can serve as protectants against T. castaneum. In the present studies, S. surrattense leaves extract was tested against T. castaneum. It was found to be most toxic against T. castaneum. A direct comparison of the potency of contact toxicities of the essential oils could not be made because different experimental methods were employed. The S. surrattense leaves extract is proven to toxic against the adult of T. castaneum, therefore, its further investigation will be made in future.

TARIQ AND M. ARSHAD AZMI MAH Qadri Biological Research Centre, University of Karachi, Karachi-75270, Pakistan Department of Zoology, University of Karachi, Karachi-75270, Pakistan (Received for publication July, 2010) ABSTRACT Survey was carried out for the prevalence of Dengue Fever Virus Vector-mosquito (DFVV-mosquito), the Aedes spp., in four Divisions (Hyderabad, Mirpur, Sukhur & Larkana) of Sindh province, during January 2007 to December 2009 (3-years). During this survey seven (7) different methods; 1) Tyre shop larval collection (TSLC)-method, 2) Tyre shop, adult collection (TSAC)-method, 3) Human residency larval collection (HRLC)-method, 4) Human residency adult collection (HRAC)-method, 5) Verbal inquiry information confirmation (VIIC)-method, 6) Night stay adult collection (NSAC)-method and 7) Literature cited information confirmation (LCIC)-method were used. Among these four Divisions, in Hyderabad Division, only at place near the entrance of Hyderabad city in between Karachi & Hyderabad on main Super High Way Road in a big tyre shop both larval & adult stage of Aedes spp., was recorded, on 27th October 2007 for the 1st time, by TSLC-method & TSAC-method and then in 2008 & 2009 as well. Whereas according to VIIC-method in some parts of Sindh province during this survey visits, such as in Hyderabad city, Badin, Mirpurkhas, Nawabshah & Naushahro Firoz, the dengue cases were reported by the people, due to Media based awareness and information. But no larval and adult collection evidence was recorded in these four Divisions except near Hyderabad city entrance. No evidence of Aedes spp., was recorded in any part of these Divisions by HRLC-method, HRAC-method & NSAC-method. In all parts of these Divisions, the malaria vector-mosquitoes, the Anopheles spp., & common dirty water-mosquitoes, the Culex spp., were recorded by all seven methods. Karachi Division has been recorded Dengue Zone since 1995, because the epidemic condition appeared in 1995, for the first time and then in 2001 and shoot up in 2006 as dengue outbreak in Karachi Division, since then it is extending to other Divisions as recorded in Hyderabad city at one place, from where it may increase and extend easily in other parts of Sindh province. Key words: Survey, Aedes, Sindh province Divisions, Outbreak of DFV in Karachi 2010. INTRODUCTION The zoological name of dengue virus vector mosquito is Aedes spp., its English common name is Asian Tiger, but now-a-days its local common name is Zebra machcher, (Zebra mosquito) due to having Zebra lining on its legs. The vector mosquito of Dengue has been reported 0.75 century ago in Asia including Pakistani areas by Barroud (1934). The dengue vector mosquito was well known for yellow fever or break bone fever (Suleman et al., 1996). In 1953 the dengue was recognized for the first time in Philippine. The pathogenesis report of dengue was reported by Halstead (1981). At present 4 serotypes Den-1, Den-2, Den-3 & Den-4 of DFV are reported. Outbreak of dengue fever virus took place at Rio de Janeiro in 1986 (Schatzmayr et al 1986). Outbreak of classical fever of dengue caused by Serotype 2 in Araguaiana, Tocantins Brazil in 1993 (Vasconcelos et al 1993). Now like malaria, dengue has also become a global problem, as reported by Pinheiro & Corber (1997), Gubler (1998). Dengue is becoming a great risk to all developed and developing countries (Monath 1994). The outbreak of Dengue Hemorrhagic fever in Karachi took place in 1995 for the first time (Chan et al. 1995). The epidemiology of Dengue virus infection among urban, jungle and rural populations in Amazon region of Peru was reported in 1996 (Hayes et al. 1996). Dengue fever; a post-epidemic sero-epidemiological survey in an urban setting at a north western country of Sao Paulo State, Brazil was reported in 1999 (Lima et al. 1999). Dengue outbreak took place in a Brazilian city (Pontes et al. 2000). In Karachi the dengue outbreak took place in 2006 in which 4000 people were infected as reported by Qadri (2006). The population of Dengue vector mosquitoes is increasing day by day in Karachi Division and its neighbouring Division Hyderabad, since 1995 as reported by Naqvi et al., (1997), Tariq & Zafar (2000), Jawad et al. (2001), Tariq & Qadri (2001), Tariq (2001), Qadri (2006), Qadri et al. (2007), Tariq & Qadri (2008), Ahmad et al. (2009), Tariq et al. (2009) & Tariq et al. (2010a), Tariq et al. (2010b) and from Hyderabad Division the vector mosquitoes are spreading to other areas of Sindh province. In the present work the prevalence of these mosquitoes in four divisions i.e. Hyderabad, Sukkhur, Larkana & Mirpur has been reported after survey visits. Tariq and Azmi 114 MATERIALS AND METHODS Talukas & Villages of Khairpur: Gambat, Ranipur, Their, Pirjogoth. Survey was done during January 2007 to December 2009 by visiting 4 Divisions of Sindh province for DFV-Vector mosquito by using seven methods viz.

RESULTS AND DISCUSSION There are 5 Divisions (Karachi, Hyderabad, Sukkhur, Mirpur & Larkana) of Sindh province. Among these Karachi & Larkana Divisions were reported positive for DFVV-mosquito, the Aedes spp., (Barroud 1934), but in the present survey report no evidence of larval or adult collection of Aedes mosquitoes has been found by any of the 7 methods used in this survey in Larkana Division. A survey reported this mosquito from Karachi Division, but not from neighbouring division Hyderabad i.e. Dadu, Badin & Thatta (Kamimura et al. 1986). Whereas in the present survey Hyderabad city was found positive, but Thatta, Badin & Dadu were not found positive by any of the seven methods. Therefore the report of Kamimura is in the line with the current survey report. By 1980’s, the distribution of this mosquito (Aedes) was limited to south eastern parts of Sindh province i.e. only Karachi Division (WHO, 1989). Naqvi et al., (1997). They reported seasonal population fluctuation of mosquito larvae in different locations of Karachi region, including Culex, Anopheles & Aedes spp., Naqvi (1992) published a survey report of mosquitoes of Karachi region in which he reported different species of Culex, Anopheles & Aedes on the basis of larval & adult collection. But in the current survey only the Aedes spp., was taken into consideration and was recorded by TSLC-method & TSAC-method only from one place near the entrance of Hyderabad city, on 27thOctober 2007 for the 1st time, and then in 2008 & 2009 as well. The Aedes spp., was not recorded in Larkana Division during this survey by any of the seven methods during 2007 to 2009, but by only LCIC-method that Larkana was reported positive for this mosquito in 1934 by Barroud. According to WHO (1989) the Aedes was limited in Karachi Division, but in this present survey, the Aedes has been also confirmed in Hyderabad division, which means that, the DFV-Vector mosquito may have been spreading by means of quick, rapid & continuous transport Survey report of Sindh province for the prevalence of DFV vector-mosquito, Aedes service by buses & railways with resting vector in them from Karachi to Hyderabad and other parts of Sindh province or by transportation of tyres from Dengue zone, the Karachi Division to Hyderabad Division, within 2-3 hours many times in a day. Ahmad et al. (2009) and Tariq et al. (2010a) have reported the whole Karachi Division as positive for DFV vector- mosquito in their survey report, including all 18 Towns of Karachi Division. Due to this reason Karachi Division has been declared Dengue zone of Sindh province. To save Sindh province it is necessary to control DFV-vector in Karachi Division on firs priority. During the current survey in 3 years (2007-2009) no larval and adult evidence has been found from any part of the four Divisions i.e. Hyderabad, Sukkhur, Mirpur & Larkana except Hyderabad city only at one place. The dengue cases reported there in these areas may be due to the infection by vector in dengue zone area i.e. Karachi or Hyderabad city during their journey period or stay in these areas, as the symptoms appear after 4-6 days after mosquito bite infection, when the patient is present in non-dengue zone area where vector is absent. Therefore the spread of DFV not takes place but only the patient of DFV appear as reported by Schwartz et al. (2000). Similar may be the case for other areas of Sindh province. As the cases are being reported in Hyderabad city, Mirpur Khas, Nawabshah, Naushahro Firoz & Sukkhur. These are those areas which are continuously connected with Karachi & Hyderabad by means of transport service. Another important point for these urban areas is that the Aedes spp., bread in the human populated urban areas as reported by Teixeira et al. (2002). This seems to be true that the two big thickly populated cities of Sindh province Karachi & Hyderabad are found positive, the same is true for Lahore in Punjab province. Now-a-days all developed and developing countries are on risk to dengue as reported by Monath (1994). Chan et al. (1995) reported Dengue Hemorrhagic fever (DHF) outbreak in Karachi (Sindh) for the 1st time, then Jawad et al. (2001) reported outbreak of DHF in Karachi (Sindh). In 2006 the Dengue Hemorrhagic fever outbreak took the epidemiological condition and more than 4000 people were infested but no control strategy for vector was adapted, due to which in 2010 after raining season due to heavy rains again we face the outbreak of DHF in Karachi Sindh. Tariq et al. (2010a) also reported two species of Aedes i.e. Ae. Aegypti and Ae. unilineatus from two different Towns, the Site & Gulshan-e-Iqbal Town. In the near future the population of Ae. unilineatus may also increase in all towns of Karachi as Ae. aegypti has been reported in all towns of Karachi. The Ae. aegypti is being increasing and extending to other divisions of Sindh from Karachi division, similarly the Ae. unilineatus may also increase and extend not only in other areas of Karachi division, but also from Karachi division to other divisions of Sindh province 115 and then the option of controlling the vector may be if not possible but very difficult. Therefore, controlling strategy should be planned currently and immediately beside the other precautionary measurements. The concentration or preference should be given more to the vector control for effective, quick and long lasting control. REFERENCES AHMED, I., TARIQ, R.M. & QADRI, S.S. (2009).

Education Foundation Govt. Degree Science College, Karachi Department of Zoology, Federal Urdu University of Atrs, Science and Technology Gulshan-e-Iqbal Campus, University Road, Karachi (Received for publication July, 2010) ABSTRACT Two species of the genus Hippotion Hubner are described in detail first time from Pakistan with special refrence to its head, venations of fore and hind wings, male and female genitalia. The Hippotion rosetta is also first time recorded and the systematic position is also briefly discussed. Key words: Revision, Hippotion, Lepidoptera, Sphingidae, Pakistan. INTRODUCTION Bell and Scott (1937) described the Hawk moths are large sized with thickly built and brilliantly coloured body with worldwide distribution. The work on various aspects were attempted by Moore (1882), Hampson (1896), Beutelspacher (1967), Kamal et al. (1968), Kernbach (1969), Darge (1970), and Grant and Eaton (1973). More (1882-83) in his Lepidoptera of Ceylon described only one species Hippotion celerio (L.) on superficial characters. Bell and Scott (1937) described five species from Oriental region. Hashmi and Tashfeen (1992) listed 32-genera in a checklist “Lepidoptera of Pakistan.” Kamaluddin et al. (1999) attempted cladistic analysis, key to the genera and distributional ranges of Sphingidae of Pakistan. Kamaluddin and Haque (2000) rediscribed Acherontia styx Westwood from Pakistan and discussed its systematic position. MATERIALS AND METHODS The Hawk moth Hippotion celerio (L.) and H. rosetta are collected from various localities of Pakistan and identified with the help of literature at hand specially Moore (1882) and Bell and Scott (1937 and I.J.Kitching, Entomologist Natural History Museum London. For the study of male and female genitalia the abdomen was detached from the base and warmed in 10% KOH for about 5- minutes, It was then washed in tap water and was inflated under leitz binocular microscope in the water. The examination of various structures were made and their diagrams were drawn by placing them on the cotton threads immersed in glycerin with the help of eye-piece graticules and were later preserved in microvials with a drop of glycerin pinned with the specimens. RESULTS Genus: Hippotion Hubner Hippotion Hubner, 1822, Verz. Bek. Schmett: 134; Roths & Jord, 1903: Revision of Sphingidae: 747; Bell and Scott, 1937, Faun. Brit. Ind. Moths 5: 413 Diagnostic features: Body generally brown with hind wing reddish, medium or small sized with gradually narrowed and pointed abdomen, frons broad, produced anteriad, palpi simple, first segment densely scaled at apex on inner side, second segment without apical tuft of scales, eyes large and lashed, proboscis very short, not passing thorax, antennae clubed in female but not clubed and longer in male. Fore wings very large, elongated, with apical angle acutely produced, anterior margin almost straight, posterior margin distinctly sinuated, veins R4 and R5 largely stalked not anastomosing with M1, M1 originating from upper angle of cell, veins Cu1 and Cu2 parallel and wide apart to each other, only anal vein 1A preset. Hind wings much shorter with anterior margin sinuated, outer margin sinuated with apical angle sub-rounded, veins Sc+R1 medially close to Rs, Rs and M1 anastomosing at base and originating from upper angle of cell, M3 originates from lower angle of cell, anal veins 1A, 2A present. Male genitalia simple, paramere oblongated with not more than 5 friction scales, aedeagus with series of dentations near distal end of theca, conjunctival lobe membranous. In female papillae anales large apophysis posteriors longer than apophysis anteriors, ductus bursae large, elongated, corpus bursae large, bag-like with large cornuti. Comparative notes: This genus is most closely related to Rhyncholaba Roths and Jord and Theretra Hubner in having apex of first segment of palpi with 118 Younus & Kamaluddin dense and regular scales on inner side, but it can easily be separated from the same in having inner margin of 2nd segment of palpi without apical tuft of scales and by the other characters as noted in the description.

Total length: Wing expanse 54 mm. Material examined: 2 males; Sindh, Malir, Karachi; on light; 10-08-96, 25-06-08; loged at Kamaluddin΄s collection. Comparative notes: This species is closely related to H. celerio (L.) in having general body pattern, structure of wings and the shape of male genitalia but it can easily be separated from the same in having body generally ochraceous, paramere with two spines near apical side and a beak-shaped process at median margin and by the other characters as noted in the description. DISCUSSION The representatives of the genus Hippotion Hubner is distributed in Paleartic, Australian and Oriental region. This genus plays sister group relationships with Rhyncholaba and Theretra by their synapomorphy like apex of first palpus segment with dense and regular scales on inner side (Kamaluddin et al., 1999). The genus Hippotion consist of six species which are recorded from the above region. Among these the species celerio plays sister group relationship with velox and outgroup relationship by its autapomorphies like hind wing with base and anal angle bright pink, palpi with basal segment much longer than 2nd, fore wing with veins R4 and R5 largely stalked but not anastomosing with M1, in male uncus stout large and curved with sharply pointed apex, in female corpus bursae large balloonlike with folded margins beset with large cornuti at dorsal surface.The species rosetta (Swinhoe) also plays sister group relationship with celerio and outgroup relationship by its autopomorphies like body generally rosecious, in male uncus highly curved, paramere with 2-spines at sub-apical margin and a beak shaped process at ventro-medium surface. 119 Illustration of figures Figs. 1-8.

(Received for publication July, 2010) ABSTRACT The external morphology of tiger beetle, Cicindela (Lophyra) histrio Tschistecherine of the family Cicindelidae carried out with detail description of the sclerites and appendages of head, thorax and abdomen. These characters are compared with other carabids and cicindelids already reported or studied and the apomorphies of the species discussed to help build a background for the cladistics of the group. Key words: Morphology, Cicindela (Lophyra) histrio, Cicindelidae. INTRODUCTION distribution of 55-species of the representatives of 14-genera. Kamaluddin et al. (2006) studied new information of genitalia of Cicindela fabicii W. Horn from Pakistan. Recently Cassola (2010) gave a list of 52-species including seven tiger beetle species first time from Pakistan. Chaudhry et al. (1970) listed and recorded five species of the genus Cicindela from various localities viz Sikkim, Assam, Burma, Bangladesh, India and Pakistan in their survey of insect fauna of forest of Pakistan. MATERIALS AND METHODS Hashmi and Tashfeen (1992) listed 65species of the representatives of six genera in their Coleoptera of Pakistan. Among these fifty five species listed under the genus Cicindela Morgan et al. (2000) studied new taxonomic status of the endangered tiger beetle Cicindela limbata albissima and discussed the phylogenetic relationships to getting evidence from mtDNA. A large number of works on different aspects were attempted by various authors throughout the world on tiger beetles viz. Erwin and Aschero (2004), Cassola and Sato (2004), Cassola (2004), Jaskula (2005), Jaskula et al. (2005). Pearson and Cassola (2005), Avgin and Ozdikmen (2007), Cassola and Brzoska (2008). Neil and Majka (2008), Cassola (2008 and 2009) and Cassola and Putchkov (2009). Cassola and wiesner (2009) described a new species, Akhteri of the genus Myriochia from Baluchistan and compared it to African species. M. (M.) dorsata Brulle and M. (M.) mirei Rivalier. Rafi et al. (2010) published a check list, faunistic of tiger beetles from Pakistan, giving biogeographic The species of Cicindela (Lophyra) histrio Tchistscherine of the family Cicindelidae were collected from various localities of Karachi District by conventional searching technique under the barks of large trees. The specimens including male and female were boiled in 10% KOH solution for 5 to 10 minutes for the study of detail external morphology. After boiling the entire specimen, the part of the body including appendages detached, wash out then examined and draw their diagrams placing these on the cotton threds under glycerine. The photograph were taken using camera where necessary. The techniques were usually followed by Kamaluddin and Najam (1995) and Kamaluddin and Hahmi (1999).

In Coleoptera the male genitalia consists of so-called “phallic” structure only Snodgrass (op.cit). The Aedeagus or male genitalia composed of sclerites and membranes arranged around the terminal portion of ducts ejaculatorius. The 9th abdominal segment takes part in this apparatus and is therefore called the genital segment, in which the aedeagus is suspended. In present species Cicindela (Lophyra) histrio tschitscherine the genital segment large elongated, rectangular shaped with proximal margin truncated and distal margin slightly convex. No further elements belonging to abdominal segments seem to be incorporated in the genital tube (Hopkins 1915, Muir 1918, Snodgrass 1935, Mischener 1994, Tuxan 1956, Kamaluddin and Najam 1995 and Kamaluddin and Hashmi 1999). Aedeagus is tubular, distally curved and narrowed with like opening, proximally broad, membranous conjunctive reduced, disto- ventrally a plate-like small thecal appendage, on which invented Vshaped hanging structure is present, the paramare (pm). Female genitalia (Fig. 22): The female genilalia of coleopteran described by Tuxan (1956), Kamaluddin and Najam (1995), Kamaluddin and Hashmi (1999) and Attique and Kamaluddin (2002) in detail. The 9th abdominal segment is an important part of external genitalia, sub-genital segment posteriorly bilobed and anteriorly divided into thron-like rami-sternite as a rule divided into a pair of hemisternites. Each hemisternite bears an articulating process, the stylus. Each stylus consist of three pieces, anterior, median an posterior pieces, the anterior piece large, anteriorly pointed, median broad, posterior divided into two rami, inner rami slightly shorter and pointed, outer rami slightly boad and large, 8th sternite trilobied lateral lobes short besets with hair. 126 Kamaluddin et al.

Abdullah (1971) described primitive and derivative characters of the families of the Coleoptera. Kamaluddin and Najam (1995) and Kamaluddin and Hashmi (1999) also discussed the apomorphies amont Nebriini and Carabini of the family Carabidae. Among the family Cicindelidae legs very long, cylinder, specially mid and lind legs about equal to body length and adapted for fast running, mandibles very long with highly developed cutting and mastically teeth, labrum with 3-7 dentiness at anterior margin and lacinia of maxilla with a large, sharp spine at distal end shows apomorphies of the family. In the present species the labrum with three dentation with median large, mandible with three cutting and five chewing dentitions, maxilla with 2nd segment about equal to combine 3rd and 4th segments, elytra with zigzag patch, in male the anterior end of aedeagus is trilobed and in female the eight segment anteriorly medially notched and the rami are of unequal sized shows its autapomorphic condition among the entire genus Cicindela.

Pakistan *1Part of Ph.D thesis of first author Correspondence: h.ali@cabi.org, hakim_sahito@yahoo.com Cell #. 0301-3515723 (Received for publication October, 2010) ABSTRACT The biology of the cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) was studied in the laboratory of Entomology section, ARI, Tandojam. Two sets of experiments were st 0 th conducted in the summer (1 June, 2008 at 25.51±2.05 C) and winter (15 November, 2008 at 16.83 ± 0 2.02 C) seasons. The insects were provided cotton green leaves and residual leaves in petridishes, respectively. There was great variation observed between each sex (♂♀) i.e. reproduction, fecundity, fertility, developmental period of immature stages longevity, survival and sex ratios. The variation was also observed between sexual and asexual reproduction. The egg developmental period during both the seasons were recorded as 1.90 days in summer and 2.90 days in winter. The oviposition (4.60±35.43) with 95.77 % fertility were recorded in summer season st nd rd and (189.60±23.20) with 86.76 % fertility in winter season. The development period for 1 , 2 , 3 instars and adult female were recorded as (5.64±0.22), (12.94±0.56), (4.34±0.37) and (22.17±0.57), respectively in summer and (8.48±0.24), (5.11±0.23), (6.24±0.51) and (51.08±0.42) in winter seasons. st Similarly, development period for 1 instar, cocoon and adult male were recorded as (5.16±0.28), (8.20±0.83) and (2.55±0.22) days, respectively in summer and (7.76±0.21), (12.66±0.28) and (3.86±0.74) days in winter seasons. Stadium time as (10.35±0.55), (6.97±0.41) and (6.63±0.43) hours were recorded after 1st , 2nd and 3rd instars in summer season and (20.49±1.39), (11.11±1.16) and (13.37±1.26) hours, respectively in winter seasons. The oviposition last for (25.73±10.41) in summer and (45.38±3.64) days in winter seasons whereas, the sex ratios (2.82♀:1♂) and (2.23♀:1♂) were recorded in summer and winter seasons, respectively. Mortality percentages 3.47, 12.48, 9.99, 7.82 and 2.35 were st nd rd recorded in eggs, 1 , 2 , 3 and adult female, respectively in summer and 7.38, 20.93, 20.15, 26.18 and 7.23 in winter season. Similarly, mortality percentages during development of adult male in various life stages were recorded as 22.71, 17.59 and 17.59 in 1st instar, cocoon and adult stages in summer season and 7.73, 11.46 and 4.28, respectively in winter season. The survival (70.02%) for female and (83.14%) for male in summer season whereas, it was (67.07%) and (55.29%) for female and male, respectively in winter seasons. The female produced more eggs (460.10±35.34) sexually in summer and (189.60±23.20 eggs) in winter as well. However, in asexual reproduction (parthenogenesis) the female produced more eggs (416.54±21.57) when fed on cotton leaf than starved female (330.81±28.44) in summer season. In winter unstarved female produced more eggs (236.60±2.93) asexually than starved female (196.50±26.76). It is concluded that more fecundity, fertility and percent survival were observed in summer season. Adult and immature lived shorter life in summer than winter season. Maximum emergence of adult female was also recorded in summer season. The starved female produced the least no. of eggs asexually.

INTRODUCTION The eruption of mealy bug on cotton and other plants in Pakistan was first recorded at Vehari Agriculture Farm, Pakistan. It has now spread throughout the cotton growing areas of Pakistan and is influencing the crop yield adversely, (CABI. 2005). In 2006, it was seen in epidemic form at Multan, Bahawalpur, Vehari and Khanewal. Cotton yield suffered a severe setback due to the attack of this insect (The daily DAWN June 2, 2006). In Sindh, southern winds below from May to September and the intercropping are very common which might have favoured this pest to infest cotton. Situation in Sindh was even worse than in Punjab. Severe damage of 132 Sahito et al. mealybug was recorded first time on an area of about 3000 acres in Kot Ghulam Mohammad, Tandoallahyar, Tandojam, Mirpurkhas and Sanghar district in 2005 and 2006. Pakistan is the 4th largest exporter of cotton in the world; this outbreak is of major economic importance. The infestation with cotton mealybug was recorded from 11 out of the 18 cotton growing areas covering 45,000 sq. km (Anonymous, 2005). (Chris Hodgson, et al. 2008) reported since 2005, a possibly introduced mealybug of the genus Phenacoccus has been causing serious damage to cotton (Gossypium hirsutum) over much of the Sindh and Punjab districts of Pakistan and in north-western India. Recently; the cotton mealybug P. solenopsis is being reported due to the invasive to the Eastern region of Sri Lanka (Prishanthini and Laxmi 2009). The mealy bug species are widespread throughout the world. Mealybugs are found outdoors in the warmer climatic zones of India, Pakistan, America, Europe, Africa, and Hawaii. Mealybugs produce large amounts of honeydew which is responsible for the development of a black fungus commonly known as sooty mold (Gullan and Kosztarab, 1997). The cotton mealybug P. solenopsis has been described as a serious and invasive pest of cotton in Pakistan and India (Hodgson et al. 2008). This kind of pest is reported from the Caribbean and Ecuador (Ben-Dov 1994), Chile (Larrain 2002), Argentina (Granara de Willink 2003), Brazil (Mark and Gullan 2005). Mealybug species have been found on a relatively wide variety of host plants including species of economically important families such as Cucurbitaceae, Fabaceae, Solanceae and Malvaceae. The first record of Phenacoccus solenopsis in Brazil, infesting tomato plants found on common weeds in Manguinhos indicating that mealybug originating from nearby weeds might had infested those crops. The feeding of mealybug may cause leaf yellowing, defoliation, reduced plant growth and in some cases death of plants (Culik and Gullan 2005). The cotton mealybug P. solenopsis pest found on china rose hibiscus rosa-sinensis Malvaceae in Nigeria (Akintola and Ande 2008). This pest also attacks to the ornamentals, vegetable, and weed plants (Wang et al. 2009) and also attacks on cotton crop in China (Wu and Zhang 2009). A mealybug has recently invaded Japan (Kawai. 2003). A similar outbreak of mealy bug on cotton was also recorded at Gujrat, India (Muralidharan and Badaya, 2000). It is also reported a decade ago from non cotton growing areas from few states of India and suggested as a non invasive pest. (Bambawale 2008) described that detailed study was done on the existence of seasonal morphological variations in cotton mealybug P. solenopsis from Indian and Pakistan sp. that provided strong support to its presence. (Hodgson et al. 2008 and Abbas et al. 2009) described the dominant mealy bug species of Pakistan as P. gossypiphilous. In the summer, the entire mealybug colony is covered in white, sticky, elastic, woolly wax, most of which is the ovisacs on the adult females. It is mainly found on the young growth, including twigs, leaves, flower buds and petioles but can occur even on the stems in heavy infestations. The infested plants become stunted, growth appears to stop and most plants look dehydrated. In severe outbreaks, the bolls fail to open and defoliation occurs; including the loss of flower buds, flowers and immature bolls. In addition, the plants become covered in a dense mat of sooty moulds, which grows on the large amount of exuded honeydew. This honeydew also attracts ants (Formicidae: Hymenoptera) of several species. The infestation of cotton mealybug P. solenopsis and its damage to cotton crop in 9 states of Indian during 2008-09 formulated strategies for management (Dharajyoti et al. 2008; Dhawan et al. 2008 and 2009; Jhala and Bharpoda 2008a; Suresh and Kavitha 2008). The mealybug P. solenopsis has a wide geographical distribution with its origin in Central America (Fuchs et al. 1991) and a survey was done in India about 47 locations during 2007-08 established the predominance of P. solenopsis (Nagrare et al. 2009); (Williams and Granara1992) reported the occurrence, severity, and epidemic forecast of mealybugs on cotton were made from Gujarat during the 2004-07 crop seasons. The involved species identified as cotton mealybug P. solenopsis and documented during these recent years by (Jhala and Bharpoda 2008b) and (Jhala et al. 2008). Keeping in view the outbreak of mealybug on cotton crop the studies on the biology of cotton mealybug was conducted to the information gained through the study and will be utilized in developing economical efficient and environmental friendly IPM studies against mealybug on cotton. MATERIALS AND METHODS Species confirmation: The reproducing females of cotton mealy bugs P. solenopsis were taken to the laboratory from experimental field (unsprayed) of CABI, South Asia model farm ARI, Tandojam from newly attacked cotton crop variety NIAB-78. Mean while the samples were sent to CABI, to confirm as cotton mealybug Phenacoccus solenopsis Tinsley. Biological and morphological studies of cotton mealybug under laboratory environment Culture maintains for biological studies: The experiments were conducted in summer (June – August, 2009) and winter (NovemberJanuary 2009). Ten females individually kept in 10 Petri dishes (4" dia) i.e. 10 replicates to record fecundity and fertility. The eggs pouches were detected from the females and the numbers of the eggs produced by each female in its pouch were counted separately. All eggs were left to be hatched in 1st instar crawlers. The time period when 50% of 1st instars were hatched out that was considered incubation period. Similarly, the development period of 1st, 2nd and 3rd instars (1st instar and cocoon in case of male) were recorded. At the transformation of adult, the male and female ratios were also recorded. Adult longevity was recorded from newly emerged adults till their death. Time period between two molts were considered as stadium. The temperature (25.51±2.05) 0C and (16.83 ± 2.02) 0C were maintained in summer and winter seasons, respectively. The photoperiod 16.L: 8.D. was uniform for both the seasons. Observations were taken at one hour intervals. During biological studies the morphological characters viz. antennae segments, body segments, caudal filaments, hairs on body parts, and setae of egg to adult were observed under microscope and photography in captured. The statistically analysis was carried out in statistical software statistics-8.1 to see the statistical difference in population. Sexual and asexual reproduction: To confirm sexual and asexual reproduction the experiments were laid in 3 treatments and 5 replications. T1 = sexual reproduction, the females of each replication were confined in Petri dishes for egg laying. Cotton leaves were provided to the female to feed. The egg pouches produced by females were detected and opened to count the number of eggs laid by female. There after, the eggs were kept for hatching. The fertility of the eggs was ascertained by counting hatched and unhatched eggs. T3 = asexual (parthenogenesis) reproduction. To record the fecundity and fertility the same procedure were adopted as in case of T1. T2 = asexual (parthenogenesis) reproduction without food. After becoming 3rd instars, the mealybugs were kept in white plastic capsule (2cm long and 0.5 cm width). They were left with out food till the end of adult stage. The egg pouches produced by the females with in the capsule were taken out and the numbers laid by the females with in the pouch were counted then the same eggs were again shifted to the capsules to record the fertility. The observations were taken at one hour intervals. The counting of 133 eggs and subsequent stage were made under microscope. RESULTS Development of Egg: The egg incubation period of the mealybug reared on both summer and winter seasons on cotton leaves indicated that minimum incubation period was recorded when reared in summer season on cotton leaves and maximum period was observed when reared in winter on cotton residue leaves. However, incubation period on cotton during summer in June 1-6-2008 revealed that minimum period was recorded from egg (1.90±0.18) days in summer on cotton followed by (2.90±0.77) on cotton residue leaves in winter off spring season during November 15-11-2008, respectively. Beside of this, it was further observed that, if eggs were kept under artificial light (100 voltage bulb) within 5 to 6 hrs. that were hatched in 1st crawler and scratches its ovarian cocoon slowly started from mouth parts and ended to behind legs. The egg hatching period was (6.21±0.26) and (12.73±1.24) in hours observed from the pouch in summer and in winter. Description of 1st instar: The numbers of antennal segments were 6 with 3 pairs of legs, without waxy powder with light yellowish colour and black eyes as newly hatched in 1st instar crawler. After few hours; whitish waxy secretion covers entire body that looks white in colour but without caudal filaments around the body. Minute hairs were seen on antennae and legs. This stage of crawlers were moving faster than other instars, this stage likes to forward to light where there is lamb, bulb or tube light observed in lab condition. After resting few days the molting process occurred to go in the 2nd instar. Therefore, the development period of 1st crawler of female mealybug (5.64±0.22) and (8.48±0.28) days were observed in summer during June-August 2008 in cotton crop season and in winter during NovemberJanuary 2008-09 whereas; male of mealybug spent (5.16±0.28) and (7.76±0.21) days in both seasons. After 1st instar it takes 1st stadium and then develops its fully foamy cover on whole body to go in to 2nd instar. Beside of this, male of mealy bug went beyond the pupation and covered foamy cocoon. Description of 2nd instar: After 1st molting, it turns up terminal abdominal part and fixes its mouth part in leaves and white powdery mass (secretion) develops. This stage is not faster comparatively to 1st instar because this stage prefers to sap the juice from injected food. It increases in size with 2 longitudinal dorso lateral 134 Sahito et al. black strips appear on abdomen first and after wards extends on thorax with gap in between thorax and abdominal black strips which remains from 2nd stage to adult besides, increasing of body. The caudal filaments appeared around the body with white wax. Number of antennal segments increased to 7 parts and lateral short bud like filaments about (9-12) pairs appear on around the thorax and abdomen in this stage. White waxy secretion (powdery mass) appears up to molting. When ever, it takes molting process it leaves foamy cover (molted cover) which, scratched with the help of legs and become soft crystal in colour. It covers new foam on whole body appeared on second day. The powdery mass is also present on caudal filaments before molting it goes to resting stage to occur the new one foam on body. Having occurred 2nd molt, powdery waxy mass disappeared due to molting and goes in the 3rd instar. For this purpose, the development of 2nd instar was longer (12.94±0.56) in summer on cotton and (5.11±0.23) in winter on cotton residue leaves. But in case of male mealybug the 2nd or 3rd instar is not present only 1st instar sup the sap from the food. After completion of 2nd instar it covers foamy cocoon where, it develops it body structure and passes (12.66±0.28) and (8.20±0.83) days and then 2nd stadium occurs in summer and winter respectively. Description of 3rd instar and adults: After molting the 3rd instar grows in larger size with powdery foam and adult of female mealybug is oval in shape and bigger size without wings with powdery wax and numerous caudal filaments. The antennae of female are with 8 parts in third instar and on 3rd day 9th part of antennae appears that is sign of fully adult and able to mate and make ovisac. In summer season parthenogenesis process occurred in lab condition study but in winter that is bit different that few produce pouch and a few have absent but ultimately produce crawlers. When the males are fully-grown, they enclose themselves in a white case in which they develop into an adult male only males pupate. Adult males are small in size comparatively to female, delicate, pair of long antennae, two-winged, and with whitish wings along, brownish in body colour, inactive mouth parts, two pair of long filaments 1st is short and 2nd one is in long comparatively to each other that helps at the time of matting to female, three pairs of legs. It has good ability to fly and search its female for matting, during this act it spends 3-4 minutes and female develops its ovicac after 3 days in summer and 5-6 days in winter and hatches eggs consequently till end and after that it dies. The 3rd instar of female mealybug observed (4.34±0.37) and (6.24±0.51) days in both seasons. After completion of 3rd instar it covers foamy structure where, it develops 3rd stadium. The life longevity of adult female (22.17±0.57); (51.08±3.42) days and male (2.55±0.28); (3.86±0.25) days therefore; the total days of female mealybug (47.69±1.92) and male (15.92±0.74) days were observed in summer and during winter the female spent much time averagely (75.00±0.94) and male (24.27±0.74) days comparatively. The morphology of male mealybug varies from female. After copulation the adult died after 2-3 days in summer and 3-4 days in winter. Study showed that female reproduction sexually as well asexually more number of female emerged than males. The mortality percentage during incubation period in pouches (3.47%) and incubation under 100 w. bulb (16.27%) in hrs. occurred and 1st instar (12.48%), 2nd instar (9.99%) and 3rd instar (7.82%) was observed. The survival percentage during incubation period in pouches; (96.52%) in days and under 100 w. bulb in hours (83.72%), 1st instar (87.50), 2nd instar (90.00%) and 3rd instar (92.17%) also observed. Thus; it is much difficult to distinguish 1st instar in male and female both are fast motile active and feed therefore; the male could be identified during develop the cocoon in 2nd stage therefore; mortality of 1st instar observed (22.71%) with the survival (77.28%) and the pupae was (17.59%) and the survival (82.40%) along with female survival ratio (258.10± 5.24) with mortality (29.97%) and survival (70.02%), whereas; in male ratio (91.50± 3.5) with mortality (16.85) and fertility (83.14) observed during summer. Further; the analysis of variance showed a highly significant (F=72.83, DF=9, P<0.001) difference among all instars of female mealybug. However, the overall means showed that the maximum day means observed on 1st instar of mealybug (Table-1). Whereas; in winter the mortality percentage during incubation period in pouches (7.38%) and under 100 w. bulb (45.62%) in hrs. occurred and in 1st instar (20.93%), 2nd instar (20.15%) and 3rd instar (26.18%) observed. Thus; survival percentage observed during incubation period in pouches (92.62%) in days and incubation under 100 w. bulb in hrs. (54.38%); 1st (79.06), 2nd instar (79.11%) and 3rd instar (73.81%) also observed. Consequently; mortality of 1st instar of male (20.88%) with the survival (79.12%) and the cocoon / pupal (45.36%) and (54.63%) with female survival ratio (69.90±2.64), mortality (32.93%), fertility (67.07%) and male ratio (31.30±1.77), mortality (44.69%), survival (55.29%) was observed at (25.51±2.05)0C and (16.83±2.02)0C with comparative R.H (47.87±1.42) and (30.73±1.46) in lab condition during these seasons. The maximum mortality was recorded in 1st instar than all other stages in winter respectively (Table-2). Biological and morphological studies of cotton mealybug under laboratory environment Description of stadiums: After 1st instar, the 1st stadium occurred that took time (10.35±0.55) in hrs. with mortality (1.35%) and survival (98.64%). After 2nd instar, the 2nd stadium occurred that took time (6.97±0.41) in hrs. with mortality (1.40%) and survival (98.39%). After 3rd instar, the 3rd stadium occurred that passed (6.63±0.42) in hrs. with mortality (0.55%) and survival (99.44%) during summer season. After 1st instar, the 1st stadium occurred that took time (20.49±1.39) in hrs. with mortality (7.73%) and survival (92.26%). After 2nd instar, the 2nd stadium occurred that took time (11.11±1.16) in hrs. with mortality (11.46%) and survival (88.53%). After 3rd instar, the 3rd stadium occurred that passed (13.37±1.26) in hrs. with mortality (4.28%) and survival (95.71%) during winter season respectively (Table-3). 135 females. Maximum fecundity (36) recorded in F-8 and minimum (9) was recorded in F-2 with mean of (20.50±1.18) and (5.26±0.80) %. The 1st instar larvae hatched from fertilized eggs varied with maximum number (513) in F-8 and minimum (217) in F-1 with mean of (382.70±4.66) were observed. Whereas, the overall mean of mealybug fecundity (330.87±28.24) % and fertility (84.74±3.06) % was observed. (T.3) parthenogenesis reproduction: It was observed that increase in temperature shortened the life of the female and male of mealybug. However, R.H had little effect on life cycle development which increases the life of both female and male mealybug. The data indicates that hatching percent varied from 80.95 to 92.40 % with mean of (89.64±2.85) % of ten females in (T.3) parthenogenesis reproduction. The unfertile eggs were recorded in all females. Maximum fecundity (32) recorded in F-1 and minimum (12) was recorded in F-6 with mean of (21.50±1.79) and (10.35±1.38) %. The 1st instar larvae hatched from fertilized eggs varied with maximum number (305) in F-5 and minimum (144) in F-2 with mean of (219.70±4.10) were observed. Further, the overall mean of mealybug fecundity (416.54±21.57) % and fertility (89.64±2.85) % was observed during biological study. Description of reproduction in summer: Description of reproduction in winter: (T.1) sexual reproduction life cycle: (T.1) sexual reproduction: The trials were conducted on 2/5/2009 to check sexual, asexual and parthenogensis reproductions in different treatments as; (T.1) sexual reproduction (T.2) parthenogenesis reproduction in one inch capsule without food / starved (asexual reproduction confirmation) (T.3) parthenogenesis reproduction (on food) observed in summer. The trials were conducted on 25/11/2009 to check sexual, asexual and parthenogensis reproductions in different 3 treatments in winter respectively. Data indicates that hatching percent varied from (86.58 to 96.59) % with mean of (91.57±3.00) % of ten females on winter season in (T.1) sexual reproduction. The unfertile eggs were recorded in all females kept in the biological study. Maximum fecundity (35) recorded in F-2 and minimum (12) was recorded in F-5 with mean of (24.60±1.38) and (8.42±1.00) %. The 1st instar larvae hatched from fertilized eggs varied with maximum number (395) in F-2 and minimum (246) in F-56 with mean of (311.80±4.35) were observed. Whereas, the overall mean of mealybug fecundity (189.60±23.20) % and fertility (86.60±3.03) % was observed. The data indicates that hatching percent varied from 78.66 to 98.13 % with mean of (93.20±3.06) % of ten females in summer season in (T. 1) sexual reproduction. The unfertile eggs were recorded in all females kept in the biological study. Maximum fecundity (29) recorded in F-6 and minimum (8) was recorded in F-7 with mean of (18.40±1.52) and (6.79±0.79) %. The 1st instar larvae hatched from fertilized eggs varied with maximum number (589) in F-4 and minimum (228) in F-5 with mean of (413.40 ±6.07) were observed. Thus overall mean of mealybug fecundity (460.10 ±35.43) % with fertility (95.77±3.11) was observed. A sexual reproduction life cycle in summer: (T.2) parthenogenesis reproduction in capsules: The data indicates that hatching percent varied from 92.98 to 97.39 % with mean of (94.74±3.06) % of ten females in (T.2) parthenogenesis reproduction in capsules. The unfertile eggs were recorded in all A sexual reproduction life cycle in winter: (T.2) parthenogenesis reproduction in capsules: The data in (Table-4) indicate that hatching percent varied from 84.78 to 97.08 % with mean of 88.41±2.94% of ten females kept in (T.2) parthenogenesis reproduction confirmation in capsules (starved). The unfertile eggs were recorded in all females. Maximum fecundity (34) recorded in F-1 and minimum (8) was recorded in F-8 with mean of 21.00±1.84 and (11.59±1.17) %. The 1st instar Sahito et al. 136 larvae hatched from fertilized eggs varied with maximum number (312) in F-5 and minimum (86) in F-4 with mean of 196.50±4.97 were observed respectively. Whereas, the overall mean of mealybug fecundity (196.50±26.76) % and fertility (76.41±2.94) % was observed. (T.3) parthenogenesis reproduction: The data indicate that hatching percent varied from 82.92 to 92.60 % with mean of (88.31±3.03) % of ten females in (T. 3) parthenogenesis reproduction. The unfertile eggs were recorded in all females. Maximum fecundity (21) recorded in F-3 and minimum (8) was recorded in F-10 with mean of 13.90±0.84 and (11.68±0.90) %. The 1st instar larvae hatched from fertilized eggs varied with maximum number (175) in F-8 and minimum (82) in F-7 with mean of (118.60±2.93) were observed. During winter female fewer emergences in reproduction and parthenogenesis with or bit ovisac / pouch observed comparatively. Whereas, the overall mean of mealybug fecundity (238.60±21.44) % and fertility (81.31±3.03) % was observed. The data given above were to confirm type of reproduction of the cotton mealyug P. solenopsis at laboratory temperature 25±2°C and (16.83±2.02)0C in summer and in winter seasons in laboratory during 2009. (T.1) sexual reproduction (T.2) confirmation of parthenogenesis reproduction in capsules (starved) (T.3) parthenogenesis reproduction data showed that the sexual and asexual reproduction hatching crawler varied from each other in both seasons. In 10 females, the unfertile eggs were recorded in all females varied from maximum and minimum number of eggs per female. The hatching percent also varied with mean numbers respectively. DISCUSSIONS The mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) was reported attacking many crops particularly cotton in Sindh. Arif et al. (2007) reported the occurrence of the same species on many crops along with cotton crop, however, the mealy bug specie Phenacoccus gossypiphyllou nomen nudum is a synonym of Phenacoccus solenopsis. Ben-Dov (1994) who described genus Phenacoccus contains about 180 species. Only three species currently share these characters: P. defectus Ferris, P. solani Ferris and P. solenopsis (Williams, 2004) but all three are present in Central and South America (Williams & Granara De Willink, 1992; Ben-Dov et al., 2007). Its novelty was also suggested by (Sahito et al. 2009). The results of present studies further reveals that there was great variation between reproduction, fecundity, fertility, developmental period of immature stages, longevity, survival and sex ratios in summer and winter seasons in lab conditions. Jhala and Bharpoda (2008) and Wang et al. (2009) described that due to the biotic and abiotic factors; it is difficult to understand about the life history and also biological activities in the field condition of the cotton crop therefore; for the purpose of biology study the lab condition is more suitable. Cox (1983) and Chong et al. (2003) described variation in biotic and a biotic factors affect the biological parameters of mealy bugs. The results further indicate that the variation was also observed between sexual and asexual reproduction. The egg developmental period was smaller in summer than winter season. Higher fertility % was recorded in summer. Shorter development periods of 1st, 2nd, 3rd instar nymphs, (Pupa after 1st instar nymph in case of male), female and male longevity were recorded in summer season. Maximum females emerged in summer than winter as compared to male. USDAUSDA-APHIS (1998) reported that the female of hibiscus mealybugs produced more than six hundred eggs in summer season. It completed its entire life cycle in 23 to 30 days. This was well supported by (Baker, 2002 and Hoy et al., 2002). Ali and Ahmed (1990) reported that in May-June the life cycle of Maconellicoccus sp. was completed in 25-30 days. Chong et al. (2003) mentioned female lived longer at 30°C. The present studies also suggest that the maximum survivorship % was recorded in all life stages in summer; however, maximum mortality was observed in 1st instar nymph in summer and 3rd instar nymph in winter. The maximum survivorship was recorded in both the sexes in summer season. Chong et al. (2008) mentioned that the average cumulative survival rate of M. hirsutus at 25 and 27°C was 72%, which was significantly higher than 51 and 62% at 20 and 30°C, respectively. Tanwar et al. (2007) attributed the buildup of P. solenopsis to abiotic changes in the environment. The same description was made by (Hodgson et al. 2008). Vennila et al. (2010) reported much shorter developmental periods of all life stages of P. solenopsis on cotton leaves (at 23.3 oC and 40.5% RH.). The female produced more eggs sexually in summer than winter. Female also produced asexually (parthenogenesis). Parthenogenesis was higher in unstarved females than starved. Ali and Ahmed (1990) reported mealybug, Maconellicoccus sp. reproduced egg asexsually (parthenogenesis). Meyerdirk (1996) studied that the eggs of mulberry mealy bug reproduction continues through parthenogenesis if there are no males.

Agricultural Biotechnology and Phytopathology Laboratory, Department of Botany, University of Karachi, Karachi-75270, Pakistan (Received for publication October, 2010) ABSTRACT Dengue is the most prevalent mosquito-borne viral disease in people and all the four serotypes of the virus are transmitted mainly by Aedes aegypti mosquitoes. The disease has become epidemic, affecting 110 countries throughout the world and it is increasing day by day in Pakistan. There is urgent need to control the disease outbreak via controlling the vector population with minimum use of chemicals. Today use of natural products have been replacing the synthetic insecticides due to their eco-friendly nature. The marine macro algae have unique properties due to the secondary metabolites they possess. In this study we have tested 13 different species of seaweeds belongs to Phaeophyta, Chlorophyta and th Rhodophyta for larvicidal activity against 4 instar larvae of Aedes aegypti (dengue virus vector) and mortality was examined after 24 hours exposure. The ethanolic extract of Sargassum sp., has showed potent larvicidal activity (LC50=1000ppm) followed by Caulerpa taxifolia, Dictyota dichotoma var. velutricata, D. indica, Melanothamnus somalensis, Sargassum swartzii, S. wightii, S. variegatum, Stoechospermum marginatum and Stokeyia indica (LC50 = 1500 ppm). These findings may help in developing the control measures for dengue virus vector mosquito, the Aedes aegypti. Key words: Larvicidal activity, Marine Macro-Algae, Karachi Coast, DFV. Vector-Mosquito. INTRODUCTION Dengue viruses are members of the family Flaviviridae, genus Flavivirus (Henchal & Putnak, 1990; Wilder-Smith & Schwartz, 2005; Teyssou, 2009). The four serotypes of the dengue virus (DEN1-4) cause a spectrum of illness ranging from the self-limiting dengue fever (DF) to more severe, life threating forms of the disease termed dengue hemorrhage fever (DHF) and dengue shock syndrome (DSS) (Balmaseda et al., 2005). The dengue is continues to spread throughout tropical and subtropical regions world wide, affecting an estimated 50-100 million people each year (Gibbons & Vaughn, 2002). Whereas Teyssou (2009) reported that dengue is affecting 110 countries throughout the world and placing over 3 billion people at risk of infection, where 70-500 million persons are infected every year including 2 million who develop hemorrhagic form and 20,000 die (Teyssou, 2009). In Pakistan, dengue is emerging one of the most serious life threating disease (Tariq & Zafar 2000, Tariq et al. 2010). It is the most prevalent mosquitoborne viral disease in people and all the four serotypes of the virus are transmitted mainly by Aedes aegypti mosquitoes (Deen et al., 2006). Susceptible humans become infected after bitten by an infected female Aedes mosquito and infected person develop dengue fever within three to seven days (Gubler, 1998). There is no specific treatment of dengue and prevention requires control of vector mosquitoes which is difficult to implement and maintain (Teyssou, 2009). As the mosquitoes are the vector for large number of human pathogens than any other group of arthropods (El-Hag, et al., 1999), it is reasonable to control this vector on priority, rather than treat the patients after infection. There is an urgent need to develop the effective ways for the management of virus outbreak via controlling the vector. The poor effectiveness of the control strategies (Medronho, 2008) and non target, specific nature of synthetic insecticides and larvicides had lead an increased number of investigations aiming to find novel larvicidal agents in natural products (Tariq & Qadri. 2001; Selvin, & Lipton, 2004; Manilal, et al., 2009; Alarif, et al., 2010). Considerable evidence has been accumulated in recent years to support and identify the benefits associated with the use of seaweed in pest and disease managements. Application of seaweed have been reported to decreased levels of nematode attack on plants (Wu et al., 1997; 1998) and root rotting fungi (Sultana et al., 2007, 2008, 2009). In our previous studies we have reported the nematicidal effect on Meloidogyne javanica (Ara et al., 1998), cytotoxicity on brine shrimp (Ara et al. 1999), antibacterial (Ara et al., 2002a) and hypolipidaemic (Ara et al., 2002b) activities of seaweed of Karachi coast. The present report Hira, et al. 144 describes the mosquito larvicidal effect of some seaweeds. MATERIALS AND METHODS Algal material: Thirteen seaweed species, belonging to Phaeophyta (Dictyota dichotoma var. velutricata, D. indica, Sargassum swartzii (Turn.) C. Ag., S. tenerrimum J. Ag., S. variegatum, S. wightii Grev. Sargassum sp., Spatoglossum asperum J. Ag., Stoechospermum marginatum C. Ag., Stokeyia indica Thivy et Doshi, Chlorophyta (Caulerpa racemosa (Forsk.) J. Ag, Caulerpa taxifolia (Vahl) C. Ag.) and Rhodophyta, Melanothamnus somalensis were collected from the coast of Karachi (Buleji beach) at low tide, washed and dried under shade. The dried seaweed were grinded to powder and stored in polyethylene bags at room temperature until used. Preparation of ethanol extract: 500 gm of seaweed species were macerated in ethanol (2 liter) for a week. The extracts were pooled and filtered through cotton wool, concentrated to semisolid state on rotary vacuum evaporator at 40ºC. Larvicidal activity: The eggs of dengue virus mosquito (Aedes aegypti) were collected and allowed to hatch and proliferate in normal laboratory conditions. The young fourth instar larvae were used for experiment feed with powered shrimps (Siddiqui, et al., 2009) Ten fourth instar larvae of Aedes aegypti were transferred to 50 ml beaker containing 20 ml of tap water. Ethanol extract of seaweeds were added to prepare a concentration of 500, 1000, 1500, 2000 and 2500 ppm. Larvae kept in tap water without seaweed extract served as control. The mortality percentage of the larvae was recorded after 24 hours exposure. The experiment was conducted five times and data were analyzed and LC50 values were calculated for each sea weed according to Abbot’s formula (1925). RESULTS The ethanol extract of seaweeds showed significant larvicidal activity by killing the 4th instar larvae of Aedes aegypti at varying degrees (Table 1). Out of 13 species tested one Sargassum sp., showed most effective results (LC50 = 1000 ppm) after 24 hrs. Whereas, Caulerpa taxifolia, Dictyota dichotoma var. velutricata, D. indica, Melanothamnus somalensis, Sargassum swartzii, S. wightii, S. variegatum, Stoechospermum marginatum, Stokeyia indica, were moderately effective (LC50 = 1500ppm). The ethanol extracts of Caulerpa racemosa and Spatoglossum asperum were lethal for larvae at higher doses (LC50=2000). Dictyota dichotoma var. velutricata, D. indica, Melanothamnus somalensis, Sargassum swartzii, S. wightii and Sargassum sp., Stoechospermum marginatum and Stokeyia indica at concentration of 2500 ppm caused 100 percent mortality of mosquito larvae (Table 1). DISCUSSION The number of cases of severe dengue disease continue to grow in endemic areas of Southeast Asia, Central and South America and other subtropical regions (Whitehead et al., 2007). In Pakistan dengue has become endemic since last decade. There is no specific treatment for dengue and prevention requires control of vector mosquitoes that is difficult to implement and maintain (Teyssou, 2009). There is an urgent need to control the vector population for controlling this viral disease. However, the indiscriminate use of insecticides has been causing environmental pollution and toxicity to nontarget organisms including human being (Brown, 1983). In the present study some seaweeds of Karachi coast have shown significant mosquitoes larvicidal activity in vitro. There are reports that seaweeds contain elaborated secondary metabolites that play a significant role in the defense of the host against predators and parasites (Paracer et al., 1987; Ara et al., 2005). Insecticidal activity of brown seaweeds Sargassum wightii and Stoechospermum marginatum may be due to the presence of insecticidal compound bis (2-ethylhexyl) benzene1,2-dicarboxylate (Katade, et al., 2006). In this study, Caulerpa taxifolia, Dictyota dichotoma var. velutricata, Sargassum swartzii, Sargassum variegatum, Sargassum wightii and Stokeyia indica have shown insecticidal activity at LC50 =1500 ppm. The secondary metabolites, caulerpin and caulerpinic acid isolated from Caulerpa species have shown larvicidal activity (i.e., >50% lethality at 500 µg ml- (Alarif, et al., 2010). Similarly, Thangam & Kathiresan (1991), have tested 15 different seaweeds for their mosquito larvicidal activity, and they found Caulerpa scalpeliformis and Dictyota dichotoma were most effective with LC50 values of 53.70 and 61.65 mg/l respectively. Other researchers also reported the insecticidal activities of different seaweeds species (Maeda, et al., 1984; Selvin & Lipton, 2004; Manilal, et al., 2009). Similarly anti-plasmodial activity of green algae Ulva species against Plasmodium falciparum has also been reported (Osterhage, et al., 2000). The secondary metabolites of marine macro-algae have opened exciting avenues for new researches. The secondary metabolites include polysaccharides, triterpenes, flavonoids, sterols and other oily compounds. ElGamal (2010) has reported that mono & diterpenes isolated from seaweeds have insecticidal activity. Seaweeds are found in abundance at Pakistani coast of Arabian sea, and in future these may be used as a safe bio-insecticide for the control of mosquitoes particularly Aedes aegypti, a vector of dengue virus.

Six sunflower varieties namely; HO-1, M-I, M-II, M-III, M-IV and Suncross-42 were grown in a st rd randomized complete block design. Maximum population of whitefly was recorded at 1 peak in 3 week of November than 2nd peak in 4th week of December. The highest population of whitefly at 1st peak was -1 recorded on HO (9.01 ± 0.23/ leaf), followed by M-II (8.94 ± 0.24), M-IV (8.87 ± 0.28), M-III (8.75 ± 0.38), Suncross-42 (8.38 ± 0.29), and M-I (8.18 ± 0.41), respectively. Jassid displayed their more rd st activities 3 weeks before the maturity of the varieties in the 1 week of January. The highest population of jassid was recorded on M-I (2.73 ± 0.14) followed by HO-I (2.26 ± 0.24), M-III (2.12 ± 0.46), Suncross42 (2. 05 ± 0.24), M-II (2.04 ± 0.25) and M-IV (1.46 ± 0.26). The results indicated that the population of whitefly and jassid appeared on all varieties from germination till maturity of the crop. LSD showed that Suncross-42 and HO- behaved similarly, whereas, M-I, M-III and M-IV had the same response to whitefly population. While, in case of jassid attack M-III and Suncross-42 behaved similarly. On the basis of the above results none of the varieties tested were found resistant to the attack of both the insect pests. Key words: Jassid, whitefly, sunflower, varietal resistance. INTRODUCTION Sunflower, Helianthus annuus L., is a major oilseed crop of the world. After soybean, sunflower can be grown successfully in the arid as well as semi-arid regions of the world. This crop was introduced in Pakistan during 1960’s. It gained popularity in the country because of its high returns and oil quality. It can play a pivotal role in the domestic increase of edible oil production. It is grown during spring and autumn seasons on about 315,000 acres annually with an average production of 1600 kg per hectare (Anonymous, 2006). However, its average yield is lower as compared to that of advance countries. The reason for its low yield can be attributed to many factors. Among them, insect pests are an important one. It is vulnerable to the attack of insect pests such as whiteflies, jassid, aphids, army worm, heliothis (Lohar, 1984). Among these insect pests, whitefly and jassid are the key pests of this crop (Lynch and Carner, 1980 and Tayler, 1981). Whitefly, Bemisia tabaci Genn. stands out as the most important member of the family. Aleyrodidae for its grave impact on tropical and subtropical agriculture. It is highly polyphagous and has been recorded on more than 500 plant species including numerous field crops, ornamentals and weeds. The fly can cause serious direct or indirect damage to sunflower crop (Basu, 1995). Jassid, Amrasca devastans Dist. an important member of the Cicadellidae, is a polyphagous pest having a wide range of host plants. Clusters of nymph and adults may be seen on the leaves, sucking cell sap from the mesophyll and injecting toxins, causing damage to sunflower leaves. This pest causes huge loss to the crop every year (Lohar, 1987). Looking to the pest and importance of the sunflower crop, an experiment was conducted on the varietal resistance of some upcoming varieties of sunflower crop against whitefly and jassid. The ultimate object of the study is to find out genetically resistance and susceptible varieties of sunflower against the attack of these insect pests. So that it may give guidelines to IPM workers. MATERIALS AND METHODS A field experiment was conducted on varietal resistance of sunflower crop against whitefly, Bemisia tabaci Genn. and jassid, Amrasca devastans Dist. at Oilseeds Section, Agriculture Research Institute, Tando Jam during autumn season 2009. Six sunflower varieties namely, HO-1, M-I, MII, M-III, M-IV and Suncross-42 were grown in a fourreplicated randomized complete block design, each sub plot was measuring 3x5 m. Four rows were planted in each subplot. The distance between rows was maintained as 45cm and plant-to-plant 15cm. All agronomical operations were equally applied to all plots. Lanjar and Sahito 148 The population of jassid was recorded by counting adults and nymphs and in case of whitefly only adults were counted. The population of respective pests were recorded at weekly intervals (after germination up to crop maturity) for recording the population of the pest, 15 leaves from each subplot were examined. These leaves were selected randomly from different nodes of sunflower plants in each subplot. The data were subjected to analysis of variance. In order to test the superiority of varietal means, L.S.D. test was applied. RESULTS The mean weekly pest populations of Bemisia and Amrasca devastans observed on six sunflower varieties is presented in Tables-1 and 2. The data recorded on sunflower crop is throughout cropping season. I. Whitefly, Bemisia tabaci Genn The adults of B. tabaci were found that they suck up the cell sap from lower surface of the leaves during this investigation. It was observed that the population of whitefly varied significantly on all six sunflower varieties with the time intervals from seeding to crop maturity. In initial stage, the population was low in HO-1and Suncross-42. However, the population on M-I, M-II, M-III, M-IV varieties was not less than 5 adult flies per leaf. The first peak of whitefly population was recorded in the 3rd week of November. At this time, the highest population (9.01 ± 0.23) per leaf was recorded HO-1 followed by M-II (8.94 ± 0.247), M-IV (8.87 ± 0.286), M-III (8.75 ± 0.382), Suncross-42 (8.35 ± 0.295), and M-I (8.18 ± 0.410), respectively. The second peak was recorded after one month time in 3rd week of December. At the 2nd peak, maximum population (8.52 ± 0.340) per leaf was recorded on M-II followed by Suncross-42 (7.22 ± 1.22), M-III (6.66 ± 0.417), M-I (6.35 ± 0.345), HO-1 (6.10 ± 0.457), and M-IV (5.03 ± 0.635). However, the overall means in Table-1 showed among those varieties M-II was the most preferred/ susceptible and Suncross-42 was the least preferred to the whitefly. The analysis of variance showed significant difference in the population between the sunflower varieties, However, L.S.D. showed non-significant difference in the population recoded on Suncross-42 and HO-1, and between M-I, M-III and M-IV at (P<0.05). The increasing occurrence of the whitefly Bemisia tabaci on poinsettias and the loss of efficacy of insecticides enhance the importance of biological control measures against this pest. (Klatt and Nennmann. 2002). These pests inflect heavy damage that occur in all the growing areas but are problematic in seedling stage. In some places, whitefly is emerging to be as serious problem. Besides; jassid is active right from seedling to reproductive stage. (Thapa and Basnet. 2008). II. Jassid, Amrasca devastans Dist. It was found both in the adults and nymphs suck up the sap from under side of the leaves of sunflower plants. Due to their attack, the affected leaves first turned down then curled up and afterwards became pale yellow. The pest remained active through-out the season as shown in the data given in Table-2. However, the population was found fluctuating through-out the season. Initially, very low population was observed on the plants of all varieties, which was less than 1 jassid per leaf. Population of jassid was increased very proportionally to the growth of the plants. Two peaks in the population were recorded, the first peak in the 1st week of December and the second in the 1st week of January. At the first peak, the maximum population of jassid per leaf was recorded on M-I (2.48 ± 0.14) and the minimum (0.76 ± 0.073) on HO-1. The second peak, maximum population was recorded on M-I (2.73 ± 0.140). And minimum population occurred on M-IV (1.46 ± 0.269). This trend was not as same as 1st peak. The overall means showed that the abundance of A.devastans on all six varieties of sunflower. Variety M-I had more jassids and HO-1 had least. Analysis of variance showed significant difference in population of jassid between the varieties at one present level of probability. However, L.S.D. showed non-significant difference between the population of jassid on M-II and M-IV; M-III and Suncross – 42, respectively at (P< 0.05). The variety M-I proved more susceptible to the attack of jassid because it had well-developed veins network on leaves as compared to HO-1 and Suncross-42. As nymphs of jassid always preferred have maximum population near these veins. The result is closely agreed with those of Rohilla et al. (1982) who supported that the more population of jassid was recorded at later phase of the crop mainly due to wide leaves and having welldeveloped veins. Sattar et al. (1983) conducted experiment and concluded that Bemisia tabaci and Amrasca devastans were found attacking 8 cultivars of sunflower crop. Malmad et al. (1980) mentioned that Bemisia tabaci developed and increase on sunflower during recent years. Migration takes place after maturity of cotton crop. Jamali (1984) concluded that hybrid was more resistant to the attack of B. tabaci and A. devastans as compared to HO-1. CONCLUSION It is concluded from the result achieved that; 1. B. tabaci and A. devastans attacked all varieties of sunflower their population was found fluctuating from germination up to maturity of crop. 2.

On Nov. 3rd, the program was started with the recitation of holy Qur’an. Dr. M. Tariq Rajput recited the verses. Then, Prof. Dr. Naimul Hasan Naqvi (the founder and Executive Editor of Pakistan Journal of Entomology, Karachi gave a brief introduction of the Society. He said that late Prof. Dr. M. Afzal Husain Qadri founded this Society in 1971. He was a zealous and great researcher who not only contributed a lot to the Society, establishment of Pakistan as a part of Choudhry Rehmat Ali and to the Entomology. He also gave courage and support to his students. As a result the Society became active and even after 40 years it is still working and progressing. The next speaker was Dr. Rubina Ghani. She is Associate Professor in Baqai Medical University, Karachi. Her topic of lecture was Application of PCR technique on the Haemocoelic fluid of insects. During her detail discourse on Polymerase Chain Reaction (PCR) she informed that PCR is a latest technique in Biotechnology through which a single piece of DNA can be amplified into millions of copies of DNA sequence. Dr. Rubina said that PCR can be used for a broad variety of experiments and analyses such as in the detection of hereditary diseases, and genetic relationships. It can be used as forensic technique moreover, a variation of this technique can also be used to determine evolutionary relationships between organisms. After Dr. Rubina Ghani the next speaker was Dr. Tahir Anwar. He is SRO in Pakistan Agricultural Research Council. Dr. Tahir talked about Gas Chromatography commonly known as a technique of identifying various chemicals including pesticides. His lecture was basically about the General principles of chromatographic analysis including sampling, extraction and clean-up procedures. He discussed that GC systems offer both excellent resolution plus sensitivity and relative ease of operation. The seminar was extended by the lecture of Dr. Farhanullah Khan on HPLC (High Pressure Liquid Chromatography) which is the most popular method of residue analysis. He described the most frequently used column material which are useful in clean-up processes for pesticide residues. The seminar was then opened for question and answer. After Zuhar prayers, a high tea was then served. The whole arrangement of seminar was done by Prof. Dr. M. Arshad Azmi (General Secretary). On the next day i.e. on 4th Nov. 2010 all the participants had been invited to Baqai Institute of Haematology at BMU where a practical demonstration program for PCR technique was given by Dr. Rubina. Before Dr. Rubina, Mr. Usman provided useful information about real time PCR and nested PCR. The practical demonstration given by Dr. Rubina, include melting, annealing, elongation and the PCR product identification by agarose gel electrophoresis. Meanwhile, a written manual about PCR methodology was provided by the organizers, to the participants. Before lunch there was a short speech of Dr. Moinuddin, Director & Incharge, Haematology B.M.U and the Vice-Chancellor, BMU, Prof. Dr. Lieut. Gen. (Rtd.) Azhar Ahmed. In the last Vice-Chancellor, Baqai Medical University distributed the certificates among the participants. The names of the participants from K.U. are as: 1. Dr. Masarrat Yousuf (Prof.) 2. Dr. M.
