The Western corn rootworm, Diabrotica virgifera virgifera, is one of the most devastating corn rootworm species in North America, especially in the midwestern corn-growing areas such as Iowa. A related species, the Northern corn rootworm, D. barberi , co-inhabits in much of the range and is fairly similar in biology.
For example, the northern corn rootworm (Diabrotica barberi) became adapted to a corn-soybean crop rotation by spending the year when the field is planted with soybeans in a diapause. [107] As of 2014, few new weed killers are near commercialization, and none with a novel, resistance-free mode of action. [108]
SmartStax seeds control a broad spectrum of pests which includes larvae of above-ground insects such as European corn borer, black cutworm, southwestern corn borer, corn earworm, fall armyworm, western bean cutworm, and below-ground feeding larvae of western corn rootworm and northern corn rootworm.
