Threshed grain was more susceptible than unthreshed grain; more progeny were produced on threshed than on unthreshed sorghum (Wongo and Pedersen, 1990).Wheat Sitophilus oryzae (lesser grain weevil, rice weevil); close up of adult. As larvas alimentam-se do interior do grão até à pupação, após a qual abrem um buraco e emergem. Sitophylus oryzae es una de las principales plagas del arroz tanto en campo como en almacén, pudiendo atacar a cualquier cereal. Many workers subsequently recognized that two distinct forms of the species existed, which were described as the 'large' and 'small' forms. Generally, both adults and larvae feed on whole cereal grains, including wheat, rice, barley, maize, groundnuts, cassava, beans, millet, and sorghum; but the females can lay eggs and develop on solid products made of cereals, such as pasta.

La larva completa su ciclo dentro del grano, donde a continuación pupa, saliendo al exterior ya como adulto tras practicar un orificio de salida.

It does not often breed in non-cereal foods, although it does attack split peas and pasta. In these revisions it was shown that Linnaeus originally described the smaller species and that Motschulsky's description of the larger species was valid.
