Abstract Whiteflies (Aleyrodidae) cause high economic losses in agricultural systems worldwide. Heavy reliance on insecticide use for whitefly control has led to the resistance development towards nearly all used groups of insecticides. A more sustainable, widely used, and irreplaceable measure protected cropping is biological by augmentative release parasitoids. All commercially available para...

Endoparasitic Hymenoptera vary in the extent to which they provision their eggs and thus in the degree to which they appear to rely on their hosts for resources during embryonic development. In this study, developmental rates were examined in two congeneric parasitoid species, Encarsia formosa and E. pergandiella, that provision their eggs to different degrees. E. formosa eggs are much larger t...
