Abstract

Until about 1965, nearly all the northern corn rootworm (NCR) reproduced a single generation yearly. Because it could only survive on cultivated corn and its dispersal stage never coincided with the beginning of a cropping season, crop rotation controlled this pest in Iowa corn fields for over a century.
