University of Nebraska-Lincoln Extension: Historical Materials

Corn rootworms (Diabrotica spp.) are one of the most economically important corn insects in Nebraska. The western corn rootworm, D. virgifera virgifera LeConte, and the northern corn rootworm, D. barberi Smith and Lawrence, are the most economically important rootworm species in Nebraska.
