Nature fights back - bugs devour GM Monsanto corn with a vengeanceSubmitted by legalizeliberty on Fri, 06/22/2012 - 09:57
(NaturalNews) Corn genetically engineered by Monsanto to kill western corn rootworm is reportedly being devoured by those pests with a vengeance. Thanks to heavy reliance on the genetically modified (GM) crops, the tiny rootworm pest has overtaken fields, outsmarting the genetic engineering that was supposed to keep it away.
Nature fights back against GM corn
The GM corn, launched in 2003, is engineered to produce a protein, known as Cry3Bb1, derived from a bacterium known as Bacillus thuringiensis, or Bt. In theory, rootworms ingest Bt corn roots and the protein is fatal. However, recent reports indicate that pesticide-resistant rootworms are showing up weeks earlier and more voraciously than ever.
In a research paper published in the July/August/September 2012 issue of the journal GM Crops & Food, scientists reported that samples taken in 2010 indicated that rootworm populations had an eleven-fold survival rate on Cry3Bb1 maize than did control populations. The paper noted that resistant corn rootworm populations first identified in 2009 had three-fold survival rates on Cry3Bb1 maize at that time compared to other populations.
