Biological Characteristics of Orius albidipennis (Hemiptera: Anthocoridae) Reared on Insect and Mite Preys

Wafaa A. Al-Kherb

This study aims to evaluate the effect of different diets on the biology and life table parameters of the minute pirate bug Orius albidipennis (Rueter) for the first time in Saudi Arabia. Immature stages of the aphid species Aphis fabae Scop., A. craccivora (Koch), Myzus persicae (Sulzer) as well as two-spotted spider mite Tetranychus urticae Koch were chosen as preys and offered to nymphs and adults of O. albidipennis at 26°C and 65% RH. Males lived for shorter time than females. The shortest duration of development was achieved when predatory insect was fed A. fabae and A. craccivora. Both aphid species shortened pre-oviposition period and prolonged oviposition which resulted in a higher rate of fecundity. A. fabae was the most suitable food source where it caused the shortest mean generation Time (T) and Doubling Time (DT) while it gave the highest rate of net Reproduction (Ro), intrinsic rate of increase (rm) and finite rate of increase (erm), followed by A. craccivora, M. persicae and T. urticae. These results should contribute to the development of mass rearing programs for biological control agents in developing countries such as Saudi Arabia.
