Online published on 31 August, 2017. Abstract A study was done to observe the biology of Angoumois grain moth Sitotroga cerealella (Oliver) on rice varieties viz., MTU-1031, WGL-3962, BPT-5204, NLR-30491, WGL-14, MTU-2077, MTU-1001, MTU-1010 and WGL-3825 under laboratory conditions. Morphometrics and other aspects of life stages were recorded on MTU-1001, which showed that the mean number of eggs laid/female was 94.76, and it ranged from 75.60 to 110.60 on different varieties. The average longevity of female ranged from 5.2 to 6.4 days and that of males from 4.6 to 5.7 days. The incubation, larval and pupal periods were found to vary from 4.2 to 5.2, 13.6 to 19.4, 5.1 to 7.5 days, respectively on the varieties studied. The total developmental period was maximum on MTU-1031 (32.1 days) and the minimum was on WGL 3825 and MTU-2077 (23.4 days).
