Enforce (Encarsia) 1000 scale (Whitefly Control)
Enforce is a tiny (0.6mm) parasitic wasp that specializes in parasitizing whitefly, specifically greenhouse whitefly (Trialeurodes vaporariorum), although it will attack other whitefly species. It is very useful in greenhouse crops as part of an Integrated Pest Management programme. Has been used successfully in crops such as tomato, cucumber, eggplant and ornamental plants.
A female wasp inserts her eggs into 3rd and 4th instar nymphs of greenhouse whitefly. The egg hatches and the wasp's larva develop inside greenhouse whitefly nymph eventually killing it.
After about 10 days, the greenhouse whitefly nymph will begin to turn black, and about 10 days later an adult wasp will emerge. Once the Enforce wasp has hatched, it will seek out more whitefly nymphs to parasitize, leaving the black case behind.
