The current studies were carried on S. oryzae L. (Coleoptera: Curculionidae), as it is considered the most destructive pest of cereals like maize, wheat, pea and rice under storage condition. The results on the biology of rice weevil on maize grains revealed that the oviposition period ranged from 4-5 days with an average of 2.76±0.176 days. The average incubation period of eggs was found to be 16.6±0.245 days and the mean fecundity rate of adult female was recorded as 307.24±8.48 eggs per female. The larval period of first, second, third, & fourth instar was observed to be 4.56 ±0.23, 6.56 ±0.09, 7.98 ±0.137 and 4.95 ±0.163 days, respectively.
