Abstract

The influence of temperature on the biological parameters of parasitoids vary according to species. In the present study, effect of temperature was evaluated on the development of pteromalid Trichomalopsis uziae, a pupal parasitoid of the silk worm uzi fly, Exorista bombycis. The results revealed that progeny production, sex ratio, and parent female longevity were significantly high at 25°C, while at cool temperatures of 10 and 15°C as well as the hot 35°C inhibited parasitism/ parasitoid development. Besides, the developmental duration of the parasitoid ranged between 12.70± 0.21 (30°C) and 23.60± 0.27 days (20°C).
