Effect of four cropping systems on variant western corn rootworm (Coleoptera: Chrysomelidae) adult and egg densities and subsequent larval injury in rotated maize.

The cultural practice of rotating corn, Zea mays L., with soybean, Glycine max (L.) Merrill, to manage larval injury by the western corn rootworm, Diabrotica virgifera virgifera LeConte, was used extensively throughout east central Illinois and northern Indiana until the mid-1990s.
