Description The effects of temperature and source of insect host (H. armigera) on the survival and development of C. chlorideae were studied. Temperatures 35°C were detrimental to the survival and development of the larvae of C. chlorideae. The post-embryonic development period of C. chlorideae was significantly and negatively associated with temperature. The parasitoid required a higher number of degree days to complete development at lower temperatures, and required a longer time (by 2.5-fold) to complete development at 18°C than at 27°C. Parasitoid development was prolonged by 6 days under ambient conditions (average of 23°C; 12-25°C) than at a constant temperature of 27°C, indicating that fluctuations in temperature have a significant influence on parasitoid development. The males and females were heavier when reared at 18 and 27°C than when reared under ambient conditions. Parasitism and adult emergence were influenced by host insect food, and parasitoid strain × temperature. The results indicated that changes in temperature as a result of climate change will have considerable influence on the survival and development of C. chlorideae.
