Abstract : The Qualitative and quantitative protection of stored grains is a prime necessity of the time. A large quantity of foodgrains is lost during storages by the infestation of various types of insect pests. Yadav( 1985) studied the ovicidal toxicity of Neem (Azadirachta indica A. Juss) Oil against callosobruchus. Prasad (1984) also suggested the population behaviour of gram bettle Callosobruchus chinensis under different storage conditions.
