Re: [Aroid-l] White Fly on Pycnospatha and others
I had white flies in my typhoniums and tomatoes in my greenhouse about three
years ago. 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.

Subject: [Aroid-l] White Fly on Pycnospatha and others
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.
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,
