Pests Are Adapting To GM Crops In Unexpected Ways
2012-06-21 05:12:02

Brett Smith for redOrbit.com Modern science is no match for Mother Nature when it comes to agriculture, a new research paper has revealed. The report, published in the Proceedings of the National Academy of Sciences by a team of scientists, showed that pests are adapting faster than expected to the genetically modified (GM) crops that have been altered to repel them. Many GM crops were originally created to reduce the amount of pesticides used to repel the insects and larvae that...

More Acreage Needed To Slow Pest Resistance To Biotech Corn

To slow resistance of western corn rootworm beetles to genetically protected crops, much larger 'refuge' acreages of conventional crops have to be planted, 2 experts warn in a paper published in the Journal of Economic Ecology Genetically modified crops that produce insect-killing proteins from the bacterium Bacillus thuringiensis (Bt) have reduced reliance on insecticide sprays since 1996. These proteins are lethal to some devastating crop pests, but do not harm most other creatures...

New University of Illinois sweet corn research shows that higher yield and profitability are possible with greater plant populations of certain hybrids. Although it's a common practice to study plant populations in field corn, U of I associate professor of crop sciences and USDA-ARS ecologist Marty Williams, said almost no research exists for determining the number of plants needed to optimize yield in processing sweet corn, which accounts for most of the U.S. sweet corn acreage. "The...

An article in the forthcoming issue of the Journal of Integrated Pest Management (JIPM) refutes claims by Greenpeace Germany that the western bean cutworm (WBC), Striacosta albicosta (Smith), is "a new plant pest" that was "caused by genetically engineered corn." The Greenpeace Germany report, which was written by author Christoph Then of Testbiotech, offers a "surprisingly simplistic conclusion" regarding the spread of western bean cutworm over the last decade, according to the JIPM authors....

A slight change in molecular structure introduced by genetic engineering gives crop-protecting proteins called Bt toxins a new edge in overcoming resistance of certain pests, a UA-led team of researchers reports in Nature Biotechnology One of the most successful strategies in pest control is to endow crop plants with genes from the bacterium Bacillus thuringiensis, or Bt for short, which code for proteins that kill pests attempting to eat them. But insect pests are evolving resistance...

Tropical maize is a valuable genetic resource that can help scientists identify the specific genes controlling daylight response. Tropical maize proves to be a valuable genetic resource, containing genetics not found in USA Corn Belt maize. Most tropical maize varieties respond to the long summer day lengths that occur in U.S. growing regions by flowering late. This delayed flowering response results in poor yields, effectively trapping the useful genes and hindering their incorporation into...

Key finding has the potential to improve corn yields worldwide Smut fungi are agents of disease responsible for significant crop losses worldwide.  Principal Investigator, Dr. Thomas Smith and Research Associate Member, Dr. Dilip Shah at The Donald Danforth Plant Science Center collaborated on a project to develop a variety of corn that is highly resistant to corn smut caused by the fungus, Ustilago maydis. The results of this research are published in the recent article, "Transgenic...
