Sitophilus is a genus of small beetles commonly known as grain weevils. They are known for their elongated bodies and distinctive snouts, which they use to bore into grains and seeds. This genus includes several species, such as Sitophilus granarius, the common grain weevil, and Sitophilus zeamais, the maize weevil. These pests are significant agricultural threats, as they can infest stored grains, leading to substantial economic losses. They reproduce quickly, and their larvae develop inside the grains, making them difficult to control. Effective management strategies include proper storage practices and the use of insecticides when necessary.
