Rootworm Biology and Behavior
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.
RNA Interference as a Pest Management Tool for Western Corn Rootworm
RNA interference (RNAi) is being developed as a potential tool for insect pest management. The most likely target pest species for transgenic plants that express double stranded RNA (dsRNA) is the western corn rootworm. This presentation will provide consultants, growers and other practitioners in the U.S. with an understanding of how RNAi works. It will also describe some recent RNAi innovations for insect pest management including in planta RNAi expression and risk assessment for RNAi technologies.
