Description

During the past summer, 2001, there was widespread and substantial lodging in central and northwest Iowa first-year cornfields. In many cases, it was determined that the rotated com was susceptible because of root destruction caused by com rootworm larval feeding. In the cases reported, the insect present was the northern com rootworm and the infestation was attributed to extended diapause that allowed the pest to survive in the rotated corn.
