Once the whitefly pupal stage is reached, the wasp larva releases digestive enzymes, and begins ingesting the semi-liquid body parts of the pupa. Close mobile search navigation Article navigation.

This is accomplished by chewing a circular exit hole. Females lay their eggs between the whitefly nymph and the leaf surface.

With the overall goal to find effective alternates to neonicotinoid insecticides for the MED whitefly management program, the specific objective of this study was to evaluate whitefly parasitoid Eretmocerus eremicus and a diamide insecticide cyantraniliprole, for whitefly control, when applied alone or in combination.


The model was used to determine the effect of insecticide treatments, sampling period and their interaction on the arthropod counts.
