Abstract
BThe effects of 4 diets on population parameters of Podisus sagittus (L.), a pentatomid predator of Lepidoptera, were compared. Direct comparisons were made of survival, stadial lengths, generation times and predator weights at 20, 25, and 33°C. Temperature influenced stadial lengths, generation time and survival but not weight. Improved survival compared with controls was recorded for diet I at 20°C and diet I and II at 25°C. On diet III adults were produced only at 33°C, in which survival was similar to that in the controls.
