The effects of six constant temperatures ranging from 15 to 40°C on the rate of development, progeny production, sex ratio and adult longevity of the grape mealybug parasitoid, Anagyrus dactylopii (How.) were determined. It was found to complete the development in the temperature regimes of20–35°C but neither sex emerged as adults at 15 and 40°C. Developmental time of male and female decreased from 32.75 to 10 days, and from 34.50 to 11.75 days respectively, as the temperature increased from 20… Expand
