(Lepidoptera, Noctuidae)
in relation to larval diet
by
SHRI RANG TRIPATHI & RAJESH SINGH
Abstract - The development of Heliothis armigera on three diets was examined at six constant temperatures. The larval stage of the pest was comparatively shorter on pigeon pea. The most congenial temperature with all foods was 22 °C, at which the percentage of mortality was lower. Pupal period also was the shortest on pigeon pea and the longest on sunflower. The most congenial temperature for pupal development on all foods was 27 °C.
