Corn borer

Corn borer, caterpillars of a moth, especially the Old World maize moth, that feeds on a variety of plants, including beet, beans, and corn. It attacked the Indian corn that was introduced to Europe, and was transported to North America about 1907 to become a serious pest in the Corn Belt and elsewhere. The use of pesticides is effective, but complicated by the need to keep the crop free from contamination. The corn borer still destroys several million bushels of corn every year.
