Appearance
Female adults: lemon-yellow
Male adults: brownish-yellow, thick antennae
Other stages: develop inside host. The larvae of the parasite move the intestines of the whitefly larvae to its periphery.
Mode of action
Female adult parasitic wasp parasitizes the larva of the whitefly. Host feeding also takes place.
Visual effect
After about 2 weeks, the first parasitized pupae can be seen in the crop. The parasitized whitefly pupa turns yellow in colour and is independent of species. The adult parasitic wasp emerges from the pupa through a round hole.
