Where does one start? On a brisk but sunny morning on the Gold Coast we set off on our field day to visit three gardens kindly opened by members of our society. The first stop was to Carol Landon’s garden at Currumbin Waters. What a lovely garden Carol. At each corner we turned there was a little nook or cranny where we could sit and admire the beautiful variety of plants such as Cordylines, flowering Orchids and of course Bromeliads, scattered amongst the trees. A large Vriesea took pride of place as you entered the garden. A few sun umbrellas adorned the garden which we all thought were for us to sit under, but no, they were for the Broms. Know where Carol’s priorities lie. Carol had built the garden up from just a few trees to the lovely garden it is today. A pleasure to visit. Our second garden of the day was Diana Bergmark’s at Ashmore. A magnificent entrance framed by manicured hedges with large statues welcomed us to this beautifully landscaped one acre property. Most of us know Diana as “the lady with the trolley” and now we know why, as scattered amongst the tall palm trees and throughout the property were the Broms Diana so carefully wheeled from the club each meeting. Here we had a relaxing lunch around the pool (no cossies could be seen) in a serene setting surrounded by shady trees and the scattering of blue pots made it a picturesque spot. The garden is a credit to Diana. Well done. Last but by no means least we arrived at our final stop for the day at Denis Mills Garden at Carrara. Upon arriving we were met by these magnificent flowering Bougainvilleas cascading along the fence and framing the front of the house. We thought this was the highlight of the garden until we ventured into the back. It was simply stunning. Broms, Cordylines and Succulents were all interplanted on a beautiful contoured area with a number of Broms attached to Golden Palms and along with the fountain, complemented the picture perfect scene. Dennis has cleverly built some interesting wall hangings where he has attached mini Broms and also grows herbs from the top of the planter, easy picking from the patio. He will have to bring one of these hangings to the club for a “show and tell”. On the patio a display of succulents bought together by the fact they were all in white pots created a very nice display. Once again, an interesting and delightful garden. A Page 4 lovely day was had by all and many thanks to Carol, Diana and Denis for their hospitality and sharing their gardens with us. Although Marjorie was not available on the day, a special thanks to her for organising a very successful field trip. By Kay Edwards __________________________________________________________________________ Open gardens Saturday 20th October To commence at John & Julie Crawford’s, 20 Sugargum Crescent, Molendinar, an amazingly set-out Bromeliad production garden in an attractive fashion. You are sure to enjoy the information you will be given. Morning tea will be available before we leave for the next garden, at 10.30 am & head for Mt. Tamborine. Bruce & Heather Condon of 378 Main Western Road will welcome us at 11.30. These kind people are members of Ipswich club & intend to join us soon. Lunch will be in the Botanical Gardens. Our club will provide hot water. Then your time is your own. It's spring! so the mountains should be a picture. Looking forward to meeting many of you on the day, to share in fun & friendship while learning.

A bit of history - as to why I am doing this research. The Townsville City Council in Queensland has been prosecuting people for having mosquitoes in their bromeliads. They have advertised these plants as the arch enemy. I contacted the World Health Authority asking for any research where Aedes aegypti, the mosquito carrying Dengue Fever has been found breeding in bromeliads. The latter are of no concern to them so far as Dengue Fever is concerned as only two cases of finding larvae in bromeliads have ever been reported and tthe he number of wrigglers was negligible. The Council (Health Department) is saying bromeliads are bad in the tropics while I am saying that we in the dry tropics, like Hawaii, have the best growing and colouring up conditions in the world. Bromeliads should be promoted as a tourist attraction here in the tropics. Somewhere between the two is probably correct. The Townsville City Council (Parks and Gardens) is helping me resolve this dichotomy by supplying me with some of their larger bromeliads to add to my study tudy so that I would have a larger range of genera and species than I had in my pilot study. While I was waiting for new growth of pest free plants, and waiting for the vases to become large enough to possibly attract mosquitoes I made a strange observation. n. The council supplied plants were getting mosquitoes in some of their plants while my plants weren't. How could this be? Was someone trying to show me that we were both right? I had proposed in my previous publication that I believed there could be a che chemical mical inhibitor to mosquito released by bromeliads. My wild unspoiled plants up the trees never had mosquitoes in them in 30 years so my hypothesis sounded reasonable. After all some carnivorous bromeliads are known, so we know they can utilise flesh. If this his is true why were the council ones performing differently? My son, Dr. Mark Smythe working at University of Queensland read and forwarded to me an article found in their newsletter stating that a predator of mosquitoes called Mesocyclops had been found by a Dr. Michael Brown working at the Queensland Institute of Medical Research. My garden has been pesticide free for thirty years while council plants would have been sprayed. Could the council have killed a predator? Now that I have started asking questi questions ons I feel that I can explain my findings better in a Question and Answer format. Predators that is my favourite word at the moment. I have spent a lot of time studying the water in vases of bromeliads, and so far have found several predators worthy thy of my research. As I am now retired, I do not have the funds to Page 6 exactly identify these so accept my names with some reservation, that is, until someone gets paid to research them properly. What are Mesocyclops? Mesocyclops are found in the bromeliads with clearer water. These have only recently been discovered as a mosquito predator by Dr. Michael Brown working at the Queensland Institute of Medical Research. They are very small and just visible to the naked eye. They zig and zag about often carrying two large egg sacks. Several researchers are using these creatures to study mosquito breeding in mine shafts and water tanks. These fellows keep my bromeliads free of mosquitoes right through the year up until the heat and heavy rains of summer. They are now gone, dead or washed out of my bromeliads. They do not like putrid conditions and do best in clearer waters in cooler conditions, however they can be replaced after the heat of summer. (Uncle Derek says they look like very miniature Mitsubishi logos if you clean your bifocals) Where can I get the predators? Up here in Townsville one looks for a pond that has no fish or tadpoles and as yet no wrigglers. It (the pond) is under predator control if it has not been sprayed. I brought the water home from two ponds and set up my own tubs in the yard. I have never had to top it up, but I do watch that my ponds do not get too hot or polluted. Midges have come to the ponds of their own accord and can be found in most neglected collections up here. Are there any other predators? Blood worms, these little creatures are small red aquatic worms which multiply via some weird divisionary process. They hatch into non-biting midges. These appear to be predators only in the sense that they can kill wrigglers; I have never seen them eat the wrigglers, though some midges can be carnivorous. While I was ill I set up glasses of possible predators around the bed, I had time to observe these creatures. Using wine glasses to simulate bromeliads, wrigglers came down to the bottom where the worms were concentrated. Anything touching the worm was wrapped in a ball of worm. These worms do not hunt. I found them in old neglected billbergias on the trees, they concentrate at the bottom of the vase, they are unusual creatures in that they can survive in putrid conditions. Their red colour is due to their possessing haemoglobin like ours. This concentrates the oxygen in their bodies, and is apparently very rare in insects. Spirogyra, this is a filamentous algae found in ponds. When healthy, this collects bubbles and floats to the surface of the bromeliads and eventually becomes impenetrable to the wriggler, which subsequently drowns. Unfortunately, it can Page 7 hook on to the spines and be carried out of the water. It then bleaches and looks ugly so you must be prepared to push it back into the water. Bladder-worts, I have read about these as being mosquito traps in wild bromeliads (in habitat). The first one appeared in my Neoregelia burle-marxii. Maybe it was imported with the plant? When the plant was small, mosquitoes appeared, I guess it was trapping and eating my Mesocyclops. Now the plant is larger mosquitoes are not present. It may be useful, it's early days yet. How do I treat my bromeliads to minimise mosquitoes? For the dry season and incidentally the cooler season, they are totally under predator control. I rarely find a single mosquito during this period. Spirogyra is best, Mesocyclops are very efficient but so small you do not know they have died until you find mosquitoes. Do you recommend any particular spray treatment? For the wet season I spray once a week. I have written of my aversion to insecticide sprays in the environment, the spray I use is my own formula; it does not contain harmful insecticides. I mix together 50m1 Alginox, 50m1 vinegar and l00ml of kerosene shaken to make an emulsion and made up to 5 litres with water. The kerosene is used only at swarming times. I walk around and spray the plants at dusk - 5 litres covers a thousand plants. If I have too much on the leaves of delicate plants I water these plants half an hour later, time enough for wrigglers to go beyond the point of no return on the health charts. This dilute emulsified kerosene, presumably because of the oil in water emulsion formed, does not appear to damage the plants like kerosene or kerosene based sprays do. Do not be tempted to try commercial white oil. Kerosene has a low boiling point and hence higher vapour pressure and does not hang around like the damaging white oil. If I add kerosene to the spray, how long should I leave it on delicate plants? If you have delicate plants with soft new leaf, wash off 15 minutes after spraying. My studies have shown that large wrigglers die quickly but minute ones can survive 15 minutes under the spray in well-oxygenated water. Probably something to do with thinner skin and larger surface area to body weight of the smaller wrigglers. How does the spray work? The kerosene stays only long enough to smother the wrigglers. The Alginox is surfactant, which would lyse and destroy eggs. It would also change the surface tension of the water which might cause landing mosquitoes to get wet and sink, and also make it impossible for hatching mosquitoes to escape from the surface. The vinegar changes the pH of the vase water killing the larvae. Page 8 What is the easiest way to check for mosquitoes? Tip the water into a white bucket is the surest method; a white bucket will show the smallest wriggler. Should this method be impossible or even impracticable then try the battery acid tester to sample the water. Check for surfacing wrigglers looking for air after the spray treatment. Use a torch at night. All these methods will work for you. When/where am I most likely to find mosquitoes in my bromeliads? Flowering neoregelias, these have rotting flowers in the vase supplying food for the predators as well as the mosquitoes, and they release carbon dioxide as the old flower ferments. Mosquitoes are attracted to water, flesh tones, heat, and carbon dioxide. Flowered neoregelias score 3 out of 4. Shaded plants also attract mosquitoes. Very rarely do I see a mosquito hatching of any size - the worst offenders in my collection are neoregelias, frequently offending, but not big hatchings unless their water is putrid. Screwing out the spent flower removes the food source and also cleans up the plant's vase. What else can I do? When you are sitting in your garden amongst your broms having a coffee and a cigarette just drop your coffee swill and your butts into the broms. The caffeine and nicotine will kill just about everything in the animal kingdom including your pet dog! Before signing off I should point out two things. I will probably change the recommended amounts in sprays in the future as experiments need a lot of time and patience. I wish to get the Alginox as low as possible as it could harm frogs and it wipes out the desirable algae and spirogyra. The spray does not seem to worry the midges and I do not yet know what it does to the Mesocyclops. The second thing is probably obvious now, and that is, the predator method and the spray method cannot be carried out concurrently. The spray kills the algae spirogyra. In conclusion, if you use insecticide, observe closely as in some areas of the world there are mosquitoes now immune to all known insecticides. It is happening here to a degree. If I am right, the next step would be to develop chemical resistant organisms and then use integrated pest management.

Page 10 Page 11 Page 12 REPRINTED FROM BROMLINK INK 2001 – BY MARY NICHOLSON Page 13 REPORT ON THE COMBINED SHOW WITH THE ORCHID SOCIETY What a show! 2 days, 1600 people, $10,600.00 sales for our Society. Thursday afternoon set-up started with a big shuffle of tables to accommodate the entry doors/ power /cash register set-up. Marjorie & Carmon arranged a wonderful display in the entry foyer, with great plants supplied by our members. Friday, people lined-up at the doors, with 500 being admitted by lunch-time. Glenda & her helpers took care of the tea/coffee /cake, while Janice very capably looked after every ones appetite. Both rooms were filled to capacity with the orchids filling the air with their fragrance. Saturday, still more people!! with good sales up until about 2pm. The clean-up was very efficient and we were away in no time at all. Once again, many hands making light work of the whole two days. Graeme gave a “non demonstration" on repotting on both days which was well received. Congratulations to Glenda and her helpers; Janice and her crew, the ladies on the till - Carole, Ruth and the packers and not forgetting “dirty Harry” for his house-cleaning efforts! Like all new ventures, it had its hiccups!!......however, with a few "thinktanks" it ought to be bigger and better next year. P.S. well done Barbara Stultz and Peter Wright on taking-out prizes in the competition. Graeme Bullen Page 14 Tillandsia crocata Tillandsia crocata is a little gem of the family. Although it is only small it makes up for this in colour and sweet fragrance. The beautiful yellow petals and elegant fragrance are irresistible attractions. The name comes from crocatus meaning with saffron yellow. The plant grows saxicolously (on rocks) in Brazil, Argentina and Uruguay at elevations of 90-2700 metres and forms an attractive clump. The plant may be simple or few-branched and the leaves are distichous (in opposing rows). The leaves are densely covered with coarse scales. Tillandsia crocata is easy to cultivate, requires bright light, needs to be watered regularly but needs to dry out between waterings. It will grow in a range of different conditions, is fairly tough and a great favourite. Acknowledgments to Paul Isley 111 and BSI Journal. How many forms of crocata do you grow?
