Description

Northern corn rootworms (Diabrotica barberi) and western corn rootworms (Diabrotica virgifera virgifera) are perennial pests of corn (Zea mays) across the Corn Belt. Larval feeding on corn roots interferes with water and nutrient uptake, increases stalk lodging, allows entry of stalk rot pathogens, and decreases yields. Traditional methods of rootworm control include the use of insecticides (soil insecticides or seed treatments for larvae, and foliar sprays for adults) and crop rotation. The recent commercialization of transgenic Bt corn for control of corn rootworm larvae has the potential to dramatically change the way this pest complex is managed by farmers in the Corn Belt.
