Western and northern corn rootworms are serious corn pests in Iowa and the Corn Belt. These pests readily adapt to management tactics, especially in continuous corn production. The larvae consume corn roots, thereby reducing nutrient and water uptake, and cause stalk lodging. The adults may also feed on above-ground parts of the plant, including silks and pollen, which may interfere with pollination.

Western and northern corn rootworms are serious corn pests in Iowa and the Corn Belt, primarily due to their feeding habits but also because they can overcome nearly all management tactics available to farmers. The larvae tunnel into and consume corn roots, thereby reducing nutrient and water uptake and causing lodging. The adults may also feed on above-ground parts of the plant, including silks and pollen, which may interfere with pollination.
