Abstract

Ooencyrtus nezarae is an egg parasitoid of several hemipteran including the bean bug, Riptortus clavatus and is a good candidate for biological control of pest bugs. The present study focused the effects of temperature on egg maturation and longevity of Ooencyrtus nezarae as well as the interactive effect of temperature and food on its longevity. Egg maturation increased with increasing adult age, reaching a peak (between 5-10 days), thereafter declined with further advancement in age. It also increased with increasing temperature though the egg maturation ceased to occur at 35 °C. The longevity of O. nezarae was dependent on temperature and food availability. The longest longevity occurred at 15 °C providing with honey and the lowest longevity occurred at 30 °C providing with water. This study provides the biological information of O. nezarae which can be useful for biological control program as well as for its efficient mass rearing.
