A secondary insect pest is an insect species that, because of a natural or man-made
disturbance, has become an economic problem. The focus of this article will be on the
below ground insect pests in corn. These insects, especially seedcorn maggot, wireworm
and white grub, are difficult to manage because only preventive treatments are effective. An
understanding of the insect biology can help target control practices when needed.
