Abstract:
The present investigation entitled “Studies on biology and management of Angoumois grain moth, Sitotroga cerealella Olivier on stored Maize” was conducted at Abhilashi University Mandi, Himachal Pradesh during 2021-2022 under laboratory conditions. The Angoumois grain moth, Sitotroga cerealella Olivier found to be most serious pest maize crop. The study revealed that the Sitotroga cerealella Olivier develops through five larval instars, pupa and adult stages. The ovipositional, incubation, larval and pupal period of Angoumois grain moth maize crop were 3.21±0.014, 4.3±0.016, 24.78±0.042 and 6.4±0.02 days. Respectively male and female longevity of Angoumois grain moth were 5.8±0.019 and 9.1±0.025 days were recorded. Thus, the total life cycle of moth completed in 42.95±0.056 days respectively under laboratory conditions.
