Gene Expression and Behaviors Relating to Rotation Resistance in the Western Corn Rootworm, Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae)
Yearly rotation of corn with another crop interrupts the life cycle of the western corn rootworm beetle (Diabrotica virgifera virgifera, Coleoptera: Chrysomelidae), but behavioral resistance to crop rotation is a major problem. Resistant adult females exhibit reduced fidelity to corn due to …

The role of digestive proteases in the rotation-resistant phenotype of the western corn rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae)
… pest was successfully controlled by annual crop rotation, alternating maize with a non-host plant like soybean. However, massive adoption of maize-soybean rotation in east-central Illinois selected for a WCR phenotype that circumvents crop rotation by laying eggs outside of maize fields. This …

Evaluating the effect of foliar insecticides on suspected Bt-resistant western corn rootworms in rotated soybean
… substantial yield loss. Historically, crop rotation was a successful management strategy because oviposition occurred predominantly in cornfields. However, beginning in 1995, crop rotation failed to adequately manage larval injury to first-year corn in east central Illinois and northwestern …

Gut physiology and host-microbe interactions of the rotation-resistant variant of the western corn rootworm (Diabrotica virgifera virgifera LeConte) (Coleoptera: Chrysomelidae)
… fidelity to cornfields. Annual crop rotation between corn and soybean (Glycine max) has been the main strategy for controlling the WCR in the eastern Corn Belt; WCR larvae emerging in rotated soybean fields cannot survive. However, this method selected for a “rotation-resistant” (RR) …
