Against fly wasp Encarsia

larva

Encarsia formosa The parasitic wasp Encarsia formosa is applied on a wide range of greenhouse vegetable and ornamental crops to control greenhouse whiteflies. In crops with zero pest tolerance is an overkill approach recommended. Encarsia formosa lays its eggs preferably in 3rd and early 4th instar larvae. Parasitized larvae turn black and are therefore easily recognized. Parasitism of the tobacco whitefly is also possible. In this case, parasitized larvae turn brownish. During her life, a female Encarsia formosa parasitizes approximately 250 greenhouse whitefly larvae (maximum of 450) and kills another 30 (maximum of 70) by host-feeding.
