This presentation will help consultants, growers, and other practitioners in the U.S. Corn Belt understand the biology and behavior of corn rootworms, especially the western corn rootworm (WCR). The presentation begins with a discussion of rootworms as historic pests. The majority of the content is focused on details of basic corn rootworm biology, movement patterns and the characteristics of dispersing adults. Finally, the importance of biological knowledge is highlighted as a key part of making sound management decisions and understanding pest resistance.
