متن کاملCorn Rootworm Resistance to BT-Corn Reported
Cornell University by seed industry legal restrictions placed on public scientists, limiting both laboratory and field research from the mid-1990s until 2010. Widespread and organized objections by corn entomologists from major agricultural universities in 2010, convinced the seed companies to loosen the legal restrictions limiting research by public scientists involving GMO crops. As a result,...
متن کاملSynthetic feeding stimulants enhance insecticide activity against western corn rootworm larvae, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae)
The western corn rootworm, Diabrotica virgifera virgifera LeConte, continues to be a significant pest of corn (Zea mays L.) in the United States. Because of recent changes in their distribution (now in Europe; Kiss et al. 2005) the impact of this pest is growing. While a variety of management tools are still available for growers, some of the current options including crop rotation (Gray et al....
متن کاملGenetic Differentiation of Western Corn Rootworm Populations (Coleoptera: Chrysomelidae) Relative to Insecticide Resistance
As the single most important pest of field corn, Zea mays L., throughout most of the Corn Belt, the western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), has undergone repeated selection for resistance to a variety of insecticides that persist widely among Nebraska populations. In this study, we used 11 microsatellite markers to genotype two populations with...
متن کاملOn-Farm Corn Rootworm Trials
Introduction There are several methods to manage corn rootworms, including crop rotation, rootworm insecticides, and corn rootworm (CRW) transgenic traits. The use of CRW transgenic traits in corn hybrids has allowed farmers to manage CRW without using soil-applied insecticides. However, rootworm populations resistant to the transgenic traits have been confirmed in Iowa, leading some farmers to...
