Mortality and HSP Genes Expression in the Endoparasitoid Cotesia chilonis (Hymenoptera: Braconidae) After Cold Acclimation at Different Temperatures

Cotesia chilonis (Munakata) is an endoparasitoid wasp of Chilo suppressalis Walker (Lepidoptera: Pyralidea) larvae. Little is known regarding the tolerance of C. chilonis after cold acclimation at different temperatures. In this study, we investigated mortality and the molecular basis of temperature tolerance in C. chilonis reared under normal conditions (27°C) and after cold acclimation at 4°C for 5 d. We evaluated the relative expression of...
