RECENT RESEARCH ON THE WESTERN CORN ROOTWORM Western corn rootworm ( Diabrotica virgifera virgifera LeConte) population dynamics
1 The western corn rootworm Diabrotica virgifera virgifera LeConte is a major insect pest of field maize, Zea mays L. Larvae can cause substantial injury by feeding on maize roots. Larval feeding may destroy individual roots or root nodes, and reduce plant growth, stability, and yield. Costs associated with managing corn rootworms in continuous maize are annually one of the largest expenditures...
متن کاملAdaptation and invasiveness of western corn rootworm: intensifying research on a worsening pest.
The western corn rootworm, Diabrotica virgifera virgifera LeConte, is an established insect pest of maize (Zea mays L.) in North America. The rotation of maize with another crop, principally soybeans, Glycine max (L.), was the primary management strategy utilized by North American producers and remained highly effective until the mid-1990s. In 1995, widespread and severe root injury occurred in...
متن کاملPossibilities for biological control of the western corn rootworm, Diabrotica virgifera virgifera LeConte, in Central Europe
The western corn rootworm, Diabrotica virgifera virgifera, was introduced to Europe from North America in the early 1990s. It spread rapidly from its site of introduction in Serbia and is now found over some 400,000 ha of southeastern Europe. The prospects for its classical biological control by introduction of natural enemies, including pathogens, nematodes and insects, from its area of origin...
متن کاملEvaluation of Cuphea as a rotation crop for control of western corn rootworm (Coleoptera: Chrysomelidae).
The ability to prevent significant root feeding damage to corn, Zea mays L., by the western corn rootworm, Diabrotica virgifera virgifera LeConte, by crop rotation with soybean, Glycine max (L.) Merr., has been lost in portions of the Corn Belt because this pest has adapted to laying eggs in soybean fields. Cuphea spp. has been proposed as a new broadleaf crop that may provide an undesirable ha...
متن کاملRECENT RESEARCH ON THE WESTERN CORN ROOTWORM Behaviour and ecology of the western corn rootworm ( Diabrotica virgifera virgifera LeConte)
1 The western corn rootworm (WCR) is a historic pest with a legacy of resistance and behavioural plasticity. Its behaviour and nutritional ecology are important to rootworm management. The success of the most effective and environmentally benign rootworm management method, annual crop rotation, was based on an understanding of rootworm behaviour and host – plant relationships. Enthusiastic adop...
