The insect specimens collected from the stored hybrid rice seeds were Sitophilus oryzae (L.), Rhizopertha dominica (F.), Sitotraga cerealella (Ol.), and Corcyra cephalonica (Stainton). Among the insect pests infesting hybrid rice seeds the rice weevil, Sitophilus oryzae (Curculionidae) was the predominant insect pest of stored hybrid rice seed during storage. Among insecticides, botanicals and entomopathogens evaluated against S. oryzae, the data on the seed quality parameters varied significantly at nine months after storage. Emamectin benzoate 5 SG @ 40.0 mg/kg seeds have least per cent damage of 4.84 %. Significantly least seed moisture content of 12.36 per cent was recorded in emamectin benzoate @ 40.0 mg/kg of seeds. Maximum seed germination of 80.53 per cent was recorded in emamectin benzoate @ 40.0 mg/kg of seeds. Highest seedling vigour index - I was recorded in spinetoram 11.7% SC @ 0.17 ml/kg of seeds (1932) at nine months after treatment.
