I'm trying Encarsia for the first year against whitefly in the
greenhouse.
I've made the first application, and am waiting for the parisitism to
pay off.
In the meanwhil, the whitefly population is rocketing. Supplier suggests
using yellow sticky traps, but IME these are of limited effectiveness.
Any other suggestions that won't also kill off the Encarsia?

Hi Kay

I wiped out my whitefly population using 5 Drosera (Sundew) plants. The best
ones seem to be the varieties with longer thin leaves. Google will show
plenty of on-line suppliers. Place the pots in a saucer of 1cm deep
rainwater.

I never found Drosera much use against whitefly - Pinguicula seem more
effective. But I haven't got the same leaf area of Pinguicula as I have
of whitefly infestation.

I used them in a porch, where the drosera outnumbered the flowering pot
plants. In fact, no whitefly in the porch this year, but it did take 2
seasons to eradicate them.
