Results clarified that, prey-type profound effects on measured performance traits. Lowest eggs incubation period recorded for predators fed on A. craccivora nymphs, while highest observed for those fed on P. citri nymphs. Shortest total nymphal developmental period recorded for nymphs fed on A. craccivora nymphs, while longest for those fed on P. citri nymphs. Highest survival rate observed for predator that fed on eggs of E. kuehniella, while shortest recorded for those fed on P. citri nymphs. Daily female ovipositional rate was high in predator culture reared on E. kuehniella eggs comparing with those fed on P. citri nymphs. Fecundity was high for predator fed on E. kuehniella eggs, while low when fed on P citri nymphs. Adult females and males fed on A. craccivora nymphs had significantly longer life spans compared with those fed on others. Sex-ratio (%female) was significantly high when predator fed on A. craccivora nymphs.  During the nymphal period, O. albidipennis consumed significantly more eggs of E. kuehniella than other-types, whereas lowest were P citri nymphs. Adult females consumed significantly more E. kuehniella eggs than other-types, while Adult males preferred to consume A. craccivora nymphs. Data obtained suggested that O. albidipennis biology and consumption rate influenced by three tested preys. E. kuehniella eggs and A. craccivora nymphs were most favorable diet for predator. Although, P citri nymphs were less suitable for predator,but O. albidipennis could survive and reproduce feeding on it which considered as an important advantage attributed as a biological control agent.
