Abstract

Field experiments were conducted at Shbeen EL-Kom ; Menoufia Governorate during winter and Nil plantation of Eggplant, (Solanum melongena L.), Pepper (Capsicun annuun L.) belong to (family: solanacae) during (2019-2020 and 2020-2021) of growing seasons.   the survey and population dynamic (seasonal fluctuation) of Heliothes amigera on eggplant and pepper vegetable crops were the main aimed for field studies. and rearing American bollworm, Heliothes armigera (Hubner) larvae with feeding on the eggplant and pepper vegetable fruit
In laboratory showed that there was negative correlation between temperature and all studied aspects under four constant temperatures of 18, 25, 30 and 34oC each ± 1oC AThe time required for embryogenesis, larval duration and pupal duration decreased as the temperatures increased from 18 to 34oC
