Angoumois Grain Moth Infestation

Infestations of Angoumois grain moths cause serious economic damage for farmers and small growers alike. Although fresh corn is a favorite, these moths also target stores of rice, barley, sorghum, millet, wheat and dried, shelled corn. When moths invade bins, damage is often less extensive than when they lay eggs in the field, however, since they can only access the top layer of grain.

Populations can get wildly out of control when larvae mature within grain storage facilities, where they have access to a variety of grains. Many generations are possible each year, with a new generation emerging about once a month in warm weather.
