Stored-product insects are serious pests of dried, stored, durable agricultural commodities and of many value-added food products and nonfood derivatives of agricultural products worldwide. This insect passes into five generations in a year but sometimes may have 7-8 generations depend upon food and environmental condition. Cotton reported that weevil emerged in summer lives for 3-6 weeks but winter generations live longer. This insect obtained its name because it was found depredating wheat in the province of Angoumois, France, where it is known to have been imported into from the USA by the early settlers in supplies of wheat brought in from the old country.
