Origin: Rice Weevils are found through out the world, however, it is believed that they orginated in India.

Biology: Rice Weevils are called "internal" feeders. In the larva stage, they feed within grains that are whole and unbroken. Grains that they feed on would include wheat, rice, corn and various seed varieties. One common seed type is bird seed. In the adult stage, the Rice Weevil can fly. The female can live about five months and lay close to 400 eggs at a time. She will create a small hole in the grain or kernel and transfer the egg inside. Once she does this, the female then closes the hole with a film of sticky fluid. In as little as a month, the larvae will feed inside the grain or kernel in warm conditions.

Identification: Rice Weevils have a long "snout" which protrudes from the head. At the tip of the "snout" are a pair of mandibles which are used for chewing. They have bent antennae which rise in front of the eyes, on the "snout". Rice Weevils are very tiny, approximately 1/8 of an inch and are a dark black/brown color.

Control Measures: One must locate all infested products. That is very important. After you locate any products that are infested, remove them immediately and discard. Always containerize your grains and corns.
