Proceedings of the National Academy of Sciences of the United States of America, Vol. 101, No. 20 (May 18, 2004), pp. 7526-7529 (4 pages) Transgenic crops producing insecticidal toxins from Bacillus ...

Pyramid transgenic crops that express two Bacillus thuringiensis (Bt) toxins hold great potential for reducing insect damage and slowing the evolution of resistance to the toxins. Here, we analyzed a ...

Evolution of resistance in pests can reduce the effectiveness of insecticidal proteins from Bacillus thuringiensis (Bt) produced by transgenic crops. We analyzed results of 77 studies from five ...

Cornell University entomologist Anthony Shelton finds when engineered crops containing just one Bt toxin grow near modified plants with two toxins, insects may more rapidly develop resistance to all ...

Scientists are now able to insert the genes of Bacillus thuringiensis, or Bt, into farmers' crops in order to prevent a hostile takeover by pests. But what happens when the pests become resistant?

Crops genetically modified with the bacterium Bt (Bacillus thuringiensis) produce proteins that kill pest insects. Steady exposure has prompted concern that pests will develop resistance to these ...

Critics often raise concern that genetically engineered crops might harm the environment or people who eat them. But now a new study finds that farmers who plant Bt corn reduce crop damage and ...

Farmers in dozens of countries have embraced crops genetically engineered to produce proteins from Bacillus thuringiensis (Bt) bacteria that kill some key pests yet are safe for people and wildlife.

Corn rootworms, pests responsible for billions of dollars in yearly crop losses, are evolving resistance that weakens even the latest biotechnology controls, according to a new study published in the ...
