摘      要：The predatory bug,Orius majusculus(Reuter),is an important predator of thrips commercially produced for augmentative releases using the eggs of the Mediterranea n flour moth Ephestia kuehniella(Zeller).In this study,we assessed the potential for using frozen adults of fruit flies,Drosophila melanogaster(Meigen),either as nymphal rearing diet or as diet throughout the entire *** compared life-hi story traits and reproduction of predators when fed *** with high lipid body content(lipid-rich)and with high protein body content(protein-rich),using a diet of 100%*** eggs as *** also analyzed the biochemical composition of both prey and predator in order to assess the nutritional quality of each diet,which partially explained the adequacy of the different diets for *** were significant differences between predators fed the two types of ***,with the protein-rich flies as diet providing the best results in terms of mortality and ***,we show that while feeding *** throughout their development with *** increases mortality and reduces reproduction,protein-rich *** can be used as nymphal diet with minimal reduction in reproductivity and minimal increase in mortality.
