Stored grain pests are a great problem in Bangladesh and about 5-8% of the food grains, seeds and different stored products are lost annually due to stored pests infestation. About 13 species of insects have been recorded from Bangladesh which loss about 15% of stored rice. Among them, rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae) that is widely distributed, is one of the most destructive insect pests which cause severe economic loss. Rice weevils can cause losses to grain in storage, either directly through consumption of the grain or indirectly by producing ‘hot spots’ causing loss of moisture and thereby making grain more suitable for their pests. Therefore, the effective control of this insect has long been the goals of entomologists. Uncertain climatic condition, storage with debris, poor sanitation and inappropriate storage facilities encourage insect attack. In tropical countries like Bangladesh, the climate and storage conditions are highly favorable for insect growth and development. Various synthetic insecticides with different mode of action are currently used to control rice weevil infestation in stored condition but their efficacy as well as safety is really questionable. Recently, different biopesticides have been used to control the rice weevil infestations.
