ANGOUMOIS GRAIN MOTH

ANGOUMOIS GRAIN MOTH
The Angoumois Grain Moth is probably the second most prevalent moth infecting grain products. The moth has a wingspan of about half an inch, and is grayish in color. The larvae will feed on rice, corn, wheat, and other grains. It will only infect whole grains, and any products that it is found in will have a sickly smell and taste. There will be a tiny silken cocoon in the infected grain kernel.

Life Cycle
About 40 eggs are laid by the female on or near the infected product, which hatch in about a week. The larvae go though three instars in three weeks, and sometimes hibernate before changing into pupae encased in cocoons. The moth can go through two to four generations per year.
