White Fly on Pycnospatha and others

From: aroidgrower at gmail.com (John Ludwig) on 2007.08.17 at 22:44:59(16122) I have just noticed today for the first time that I have White Fly on my Pycnospatha. I have checked all other plants and also found them on a few Amorph's. +More I have just placed a new Amorph to my collection in the same area and suspect that it had the White Fly infestation. It was obviously a very recently potted, not well established plant. I check my plants every day and yesterday when I added this new arrival to my collection there was no infestation. I have since sprayed the underside of the leaves of the affected plants with "Safer Insecticidal soap." Does anybody have a different method of dealing with this problem. My plants are growing outside and I would rather use a homemade solution to these kinds of problems if I can, as I will be moving these plants indoors in about 7 to 9 weeks. Thank you for your help, John Ludwig

I used tangle traps and they were very effective. A tangle trap is a bright yellow piece of card stock covered with an adhesive. The white flies were quite happy to land on the traps and become instant permanent fixtures. There are no pesticides, chemicals, or residues. I would just punch a hole in one end of the card stock and suspend it above the infected plants. When I had finished placing the first trap, I had already captured three or four. Now the traps must be left up for several weeks after the white flies disappear. This is because the larvae left on your plants may not have matured yet. When they do, they also will fly to the traps. Happy days, Christopher +More D. Christopher Rogers Invertebrate Ecologist/Taxonomist ((,///////////=====< EcoAnalysts, Inc.

From: crogers at ecoanalysts.com (D. Christopher Rogers) on 2007.08.21 at 15:51:54(16131) Glad I could help! You mentioned the flies flying each time you bump the plant. I forgot to mention that I would routinely bump my plants to make the flies move to the tangle traps. It was very effective, and I have had no white flies the two years since.
