Genetic Basis Of Pest Resistance To Biotech Cotton Discovered
2014-05-20 12:45:36

By Daniel Stolte, University of Arizona A newly discovered genetic mechanism underlying insect resistance to genetically engineered cotton has global implications for pest management An international team led by scientists at the University of Arizona and the U.S. Department of Agriculture has discovered what happens on a molecular basis in insects that evolved resistance to genetically engineered cotton plants. Their findings, reported in the May 19 issue of the journal PLOS ONE, shed...

Study Finds Market Forces Influence The Value Of Bat-provided Services
2014-02-04 10:21:10

University of Tennessee at Knoxville Services provided by Mother Nature, such as pest control from insect-eating bats, are affected by market forces like most anything else in the economy, a University of Tennessee, Knoxville, study finds. The study's results have implications for biodiversity conservation efforts. Researchers from UT and the University of Arizona, Tucson, studied how forces such as volatile market conditions and technological substitutes affect the value of pest...

Genetically Modified Bt Crops Do Not Affect Non-Targeted Insects And Nematode Worms
2014-02-03 09:16:55

Brett Smith for redOrbit.com - Your Universe Online Some crops have been genetically modified to produce toxins from the bacterium Bacillus thuringiensis (Bt) that protect them from insect pests. These modified crops have raised concerns that they may have unintended consequences for other organisms. Two new studies have found that these crops have little or no effect on non-targeted insects and nematode worms. In one of the studies, published in the February 2014 issue of...

Corn Pest Decline Could Save Farmers Money
2013-12-19 12:41:36

Penn State Populations of European corn borer (ECB), a major corn crop pest , have declined significantly in the eastern United States, according to Penn State researchers. The decline suggests that the use of genetically modified, ECB-resistant corn hybrids -- an expensive, yet effective, solution that has been widely adopted by farmers -- may now be unnecessary in some areas. "ECB, which was introduced to North America from Europe in the 1900s, used to be the most important pest of...

Corn that contains proteins that protect it from insect damage has been grown in the U.S. since the mid-1990s. Known as Bt corn, because the proteins are derived from a bacterium called Bacillus thuringiensis, these plants have been widely grown by farmers. While Bt corn has been highly effective against the European corn borer, it has been less so against the western corn rootworm, which has been documented to show resistance to the Bt proteins. In a new article in the Journal of...

Reportbuyer.com just published a new market research report: Survey of Bio-pesticide Industry in China. London (PRWEB) October 24, 2013 Bio-pesticides are certain types of pesticides derived from such natural materials as animals, plants, bacteria, and certain minerals. For example, canola oil and baking soda have pesticidal applications and are considered bio-pesticides. With people’s rising awareness of environmental protection and food safety, more and more attention has been paid to...

Researchers at The University of Texas at Dallas (UTD), led by Dr. Lee Bulla, have demonstrated for the first time the selective cytotoxicity of Bacillus thuringiensis subsp. israelensis Cry4B toxin is mediated by BT-R3. The Cry toxins produced by Bacillus thuringiensis exert their insecticidal activity by binding with high-affinity to their cognate cadherin receptors located on the surface of epithelial cells that line the midgut of susceptible insects. In the case of Anopheles gambiae,...

A benign crystal protein, produced naturally by bacteria and used as an organic pesticide, could be a safe, inexpensive treatment for parasitic worms in humans and provide effective relief to over a billion people around the world. Researchers from the University of California, San Diego, La Jolla, CA, report on this potentially promising solution in a study published ahead of print in the journal Applied and Environmental Microbiology. Hookworms, and other intestinal parasites known as...

Gypsy Moth is staging a comeback. The BugBarrier Tree Band® helps slow the spread. Victor, NY (PRWEB) June 20, 2013 Gypsy Moths are making a comeback with a vengeance. This is causing municipalities to take drastic measures. Counties in Maryland, Virginia, Ohio, Wisconsin, Illinois, Pennsylvania, West Virginia, Washington, and Oregon have begun aerial spraying trees with Bacillus Thuringiensis in an effort to control the spread of these destructive pests. To help increase the...

Evolution Fights Back Bioengineered Crops
2013-06-11 09:04:31

April Flowers for redOrbit.com - Your Universe Online Since 1996, farmers across the globe have planted more than a billion acres of genetically modified corn and cotton that have been engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis, or Bt for short. Organic farmers used Bt proteins in sprays for decades to kill a number of devastating pests because the proteins are considered environmentally friendly and harmless to humans. Some scientists, however,...
