Corn 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 کاملBt Corn Rootworm Protected Corn: Performance and Resistance Management
Although field corn pest management has remained largely dependent on restricted-use, broad-spectrum insecticides (organophosphates, carbamates and pyrethroids) for corn rootworm control, this situation is changing rapidly with the 2003–2004 market entry of highly selective tactics, including genetically modified Bt rootworm corn hybrids and nicotinoid insecticidal seed treatments labeled for c...
متن کاملGenetic Markers for Western Corn Rootworm Resistance to Bt Toxin
Western corn rootworm (WCR) is a major maize (Zea mays L.) pest leading to annual economic losses of more than 1 billion dollars in the United States. Transgenic maize expressing insecticidal toxins derived from the bacterium Bacillus thuringiensis (Bt) are widely used for the management of WCR. However, cultivation of Bt-expressing maize places intense selection pressure on pest populations to...
متن کاملField-Evolved Resistance to Bt Maize by Western Corn Rootworm
BACKGROUND Crops engineered to produce insecticidal toxins derived from the bacterium Bacillus thuringiensis (Bt) are planted on millions of hectares annually, reducing the use of conventional insecticides and suppressing pests. However, the evolution of resistance could cut short these benefits. A primary pest targeted by Bt maize in the United States is the western corn rootworm Diabrotica vi...
متن کاملINSECTICIDE RESISTANCE AND RESISTANCE MANAGEMENT Using a Generational Time-Step Model to Simulate Dynamics of Adaptation to Transgenic Corn and Crop Rotation by Western Corn Rootworm (Coleoptera: Chrysomelidae)
We expanded a simulation model of the population dynamics and genetics of the western corn rootworm for a landscape of corn, soybean, and other crops to study the simultaneous development of resistance to both crop rotation and transgenic corn. Transgenic corn effective against corn rootwormwas recently approved in 2003 andmay be a very effective new technology for control ofwesterncorn rootwor...
