Stored grain insects cause serious loss of stored rice and degrade the nutritional value of grains. A number of plant products are active against specific target insects, biodegradable and potentially sound for use in pest management. In this study, Oils (ether Extracts of seeds) of Azadirachta indica and Sesamum indicum were evaluated for protection of rice grains against saw-toothed grain beetle, Oryzaephilussurinamensis(L.). Azadirachta indica seed extract wasused as a standard. Results demonstrated that Oils (ether Extracts of seeds) of Azadiirachta indica and Sesamum indicum leave their residues on rice for 30 days @50.0 ml/L and for 60 days @66.0 ml/L respectively.
