Corn Rootworm

Diabrotica virgifera, the Western Corn Rootworm.

This page is intended to serve as a central reference point for information about the Corn Rootworm Beetle in the midwestern United States. The Western Corn Rootworm, Diabrotica virgifera LeConte (shown above) and the Northern Corn Rootworm, Diabrotica barberi Smith and Lawrence, are both important pests of corn in the Midwest. The Corn Insect Research Project, headed by Aaron Gassmann, looks at new chemical and biological tools to use in rootworm integrated pest management.
