ARS USDA - SEPT 2010 - Rooting Out Rootworm Resistance
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 virgifera virgifera (Coleoptera: Chrysomelidae).

URBANA – Organic foods have gone from being specialty items in health food stores to lining the shelves of mainstream supermarkets. Sales of organic products have climbed from $3.6 billion to $24.4 billion in the past 10 years alone, but many consumers don’t know what makes a food organic and whether the label is worth paying for, said a University of Illinois Extension nutrition and wellness educator.

By Rady Ananda Food Freedom Nature herself may be the best opponent of genetically modified crops and pesticides. Not only plants , but insects are also developing resistance. The Western rootworm beetle – one of the most serious threats to corn – has developed resistance to Monsanto’s Bt-corn, and entire crops are being lost.

AGPROFESSIONAL 05/08/11 Iowa reports first in-field resistance to Bt corn Home > Newsroom > Iowa reports first in-field resistance to Bt corn Colleen Scherer, Managing Editor, Ag Professional | August 5, 2011 ShareThis resize text The first documented case of in-field resistance to Bt corn targeting rootworms has been confirmed recently in Iowa. Aaron Gassman, Iowa State University entomologist, and other researchers had received multiple reports of high damage to Bt corn in northeastern Iowa. The group collected adults and eggs from the area.
A team of researchers at Iowa State University (ISU) recently confirmed western corn rootworms in northwestern Iowa are developing resistance to the natural pesticide in Bt corn, raising questions about the effectiveness of the genetically engineered corn.
