Description

Three species of corn rootworms, the northern Diabrotica harbert, southern Diabrotica undecimpunctata howardi, and western Diabrotica virgifera virgifera, occur in Iowa corn. The northern and western species are capable of causing severe yield reductions. Because of this damage potential, soil insecticides are annually applied to more than 6 million acres of corn in Iowa. Not all fields have damaging populations of rootworm larvae and many would not require a soil insecticide.
