Abstract
The biology of five different genotypes of rice weevil in stored wheat was studied in the laboratory of PG Department of Botany, Jai Prakash University Chapra (Bihar). The study found that the different developmental stages of the rice weevil were longer in winter than in summer. HUW 214 recorded the lowest incubation period of 7.53 days, while HI 8498 recorded the longest incubation period of 9.68 days. HUW 214 had the lowest total larval period (23.27 days), while HI 8598 had the highest larval period (32.38 days). The total growth period was lowest in HUW 214(41.81 days) and highest in HI 8498(56.04 days).
