Mary
Brown uses Encarsia
Formosa
to control White Fly. Each adult Encarsia
lays 100-200 eggs and each egg will kill one whitefly larva. The wasp
develops inside the whitefly nymphs and emerges after 20 days.

Mary
has had no white fly this year!!!
She
orders the cards with the Encarsia on strips on the cards. She puts out a
card in the fall, in early spring-March and again 2 weeks later.
