Biology of Angoumois Grain Moth, Sitotroga cerealella Olivier on Sorghum

The Angoumois grain moth, Sitotroga cerealella Olivier is one of the most serious pests of sorghum at post-harvest. The experiment was carried out at Biocontrol Laboratory, Department of Entomology, N. M. College of Agriculture, Navsari Agricultural University, Navsari during the period from June to November, 2025 to study the biology of the Angoumois grain moth, Sitotroga cerealella Olivier on sorghum. The study revealed that the incubation period, total larval and pupal period, pre-oviposition, oviposition and post-oviposition period of Angoumois grain moth were 4.42 ± 1.03 days, 26.00 ± 1.89 days, 1.95 ± 0.78 days, 3.03 ± 0.77 and 4.28 ± 1.01 days, respectively. The average hatching percentage of egg was 87.57 ± 4.74%. The average number of eggs laid by a female moth was 100.23 ± 35.87 eggs per female. The average longevity of female moth was 9.35 ± 1.03 days while male moth lived for 7.10 ± 0.77 days. The total life cycle of female and male of S. cerealella were 43.17 ± 2.74 days and 38.30 ± 2.41 days, respectively.
