When growers plant continuous corn, corn rootworms become a severe pest problem. The planting of continuous corn suits rootworms because they lay eggs in the soil during late summer, those eggs hatch the following spring, and the subsequent larvae require corn roots to grow and develop into adults. Because corn rootworms required continuous corn, crop rotation has been, and for many areas continues to be, an effective management strategy.
