Biological control of whitefly - Encarsia Formosa

For many years, the parasitic wasp Encarsia Formosa was the only natural enemy used against whitefly. It is capable of using various species of whitefly as hosts. The female deposits her egg in older stages of the whitefly larvae. Once Encarsia has located a larva, it determines whether it is suitable to parasitize or use as food.
When Encarsia parasitizes, a new wasp will develop inside the host larva. About halfway through this process, the host larva turns black.
When the adult wasp emerges, it eats a round hole in the pupal skin.

Bought the smallest pack.

It's gonna be a massacre

I look forward to having my revenge on the whitefly that infest my greenhouse.

Can we use these parasites world wide or are they only in some countries?

does the E. formosa parasitize up to 15 species of whiteflies? and is it apocrita?
