Sitophilus Schönherr, 1838

This genus of seed-feeding weevils contains several important grain pests with a world-wide distribution. Other cereal products like stored spaghetti can also become infested, as can be various types of seeds and nuts. While these species are predominantly storage pests, they also attack ripe grain in the field in tropical and subtropical regions.

The adults are brown to black and 2-5 mm long. The females use whole grains or seeds for breeding into which they drill a hole and deposits an egg. The hole is then sealed and the hatching larva develops and pupates inside the grain.
