Diabrotica is a widespread genus of beetles, sometimes referred to as cucumber beetles or corn rootworms, in the family Chrysomelidae. Members of this genus include several destructive agricultural pest species.
Corn rootworms are one of the most economically significant consumers of maize in the United States. The western corn rootworm, D. virgifera virgifera, and the northern corn rootworm, D. barberi, are the most significant rootworm species in Iowa, a major corn-growing area. A third species, the southern corn rootworm, D. undecimpunctata howardi, causes much economic damage in other regions. The range of this genus extends farth south into South America, Diabrotica speciosa causes damage in Argentina. Corn rootworm larvae can destroy significant acreage of corn if left untreated. In the United States, current estimates show 30 million acres (12×106 ha) of corn, out of 80 million total are infested with corn rootworm. Estimates of economic damage to corn growers from the pest are about $1 billion.
