Abstract

An experiment was carried out to study the efficacy of inert materials against rice weevil, Sitophilusoryzae in milled rice grains during 2015-16 in the Dept of Entomology, OUAT, Bhubaneswar in a Completely Randomized Design (CRD) with three replications. Results indicated that the lowest population build up, grain damage and grain weight loss of 17.33 nos, 5.12% and 4.92% respectively by S.oryzae was recorded with diatomaceous earth @0.5% treatment at 150 days after treatment over the other treatments and was reported to have 93.27% inhibition rate of the S. oryzae population, 91.25% reduction in grain damage and 87.74% reduction in grain weight loss which was followed by camphor @0.5%, boric acid @0.5%, sodium bicarbonate @0.5% and salt @0.5% treatment. Similarly at 150 days after treatment the lowest increase in grain moisture content up to 13.1% was reported in the diatomaceous earth treatment over the initial moisture content of 11.5%.
