The maize weevil (Sitophilus zeamais), known in the United States as the greater rice weevil, is a species of beetle in the family Curculionidae. It can be found in numerous tropical areas around the world, and in the United States, and is a major pest of maize. This species attacks both standing crops and stored cereal products, including wheat, rice, sorghum,oats, barley, rye, buckwheat,peas, and cottonseed. The maize weevil also infests other types of stored, processed cereal products such as pasta, cassava, and various coarse, milled grains. It has even been known to attack fruit while in storage, such as apples.

A close relative of the rice weevil, the maize weevil has a length of 2.5 mm to 4 mm. This small, brown weevil has four reddish-brown spots on the wing covers (elytra). It has a long, thin snout, and elbowed antennae.Sitophilus zeamais appears similar to the rice weevil (Sitophilus oryzae), but has more clearly marked spots on the wing covers, and is somewhat larger. It is able to fly.

Although the maize weevil and rice weevil do look alike, and are easily confused with one another, there are several distinguishing features:

point

S. zeamais occurs throughout warm, humid regions around the world, especially in locations where maize is grown, including: Polynesia, Argentina, Brazil, Burma, Cambodia, Greece, Japan, Morocco, Spain, Syria, Turkey, United States, USSR, and Yugoslavia. It is also widely distributed throughout agricultural areas of northern Australia. This species has also been recorded in Canada, in the provinces of Ontario and Quebec, and has been intercepted at ports, but is not well established there. It has, however, been present for several years in Montreal, where grain from the U.S. is stored.
