he laboratory experiments were conducted to study the efficacy of some indigenous products such as plant products (chopped neem leaves ajwain seed powder, garlic capsules, saw dust), animal derivedproducts ( cow dung cake powder, cow urine) and inert materials ( ash powder, sand, talcum powder, salt) @ 2g/100g of wheat grains against rice weevil, Sitophilus oryzae (Linn.) and lesser grain borer, Rhyzoper thadominica (Fab.) on stored wheat by undertaking various parameters viz., percent adult emergence, percent seed damage, per cent weight loss and per cent germination after six months of storage during April to October 2015. After 180 days of treatments, the minimum number of adults weevils of S. oryzae( 4.00, 6.00,7.67, 9.00, 9.67 and 10.33) were emerged in wheat grains treated with ash powder, sand, cow dung powder, talcum powder, ajwain seed powder and neem leaf powder, respectively with minimum grain damage (7.33 %, 8.67 %,11.67 % and 12.00 %) was observed on ash powder, sand, ajwain seed powder and talcum powder, respectively, whereas minimum weight loss (2.67 %, 3.67 %, 5.67 % and 6.67 %) was recorded on ash powder, sand, cow dung powder, talcum powder and ajwain seed powder, respectively. Similarly, the minimum number of adult beetles of R. dominica were emerged (2.00,2.33, 6.67,7.00 and 8.33) in ash power, sand, talcum powder, cow dung cake powder and ajwain seed powder, respectively with minimum grain damage (4.00 %,8.00 %. 8.67 % and 12.67 % and weight loss (1.33 %, 4.00 %, 7.33 % and 11.67 %) in sand, ash powder, talcum powder and cow dung cake treated wheat grains, respectively. It has been clearly observed that seed germination was not affected adversely in any treatment during six months of storage. The present study clearly revealed that these naturally occurring indigenous products could be used to manage the storage insect pests in wheat.
