Corn rootworm beetles are historic pests with a troubling capacity for resistance.  They owe their success and status as our #1 corn pest to a life cycle that is intimately tied to corn.  In addition, our inability to appreciate rootworm ecology and behavior has played a particularly important role in western corn rootworm (WCR) resistance to crop rotation and Bt corn hybrids. I will use these prominent WCR management failures, and some successes, to inform our thinking about the future.  Successfully managing the WCR of the future will require that we learn from past mistakes, understand current WCR biology, and always build integrated pest- and resistance management principles into what’s new and novel.
