Beans, corn, rice, and other grains are excellent foods for insects. Stored-grain insects, such as weevils and moths, destroy billions of dollars of grain each year throughout the world. Moreover, foods prepared with insect-contaminated grain can have unpleasant flavors, be unhygienic, or even be inedible. On subsistence farms in Africa, weevily grain may be fed to the chickens or goats in the hope of rescuing a little value from it. Insect-damaged grain germinates less well and is more subject to disease.
