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.
Farmers from several Midwest states began reporting root damage to corn that was specifically engineered with a toxin to kill the rootworm. Iowa State University entomologist Aaron Gassmann recently confirmed that the beetle, Diabrotica virgifera virgifera, has developed resistance to the Bt protein, Cry3Bb1.
Bacillus thuringiensis - Bt - is a bacterium that kills insects. Different proteins are engineered into cotton as well as corn plants.
