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 ...

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 ...

WEST LAFAYETTE, Ind. -- Corn farmers could learn a lesson from cotton producers: Planting crops genetically engineered to be insect-resistant works in the short run, but also could increase the number ...

I’ve finally worked my way around to the GMO question that I care about most: Are genetically modified crops boon or bane for the environment? The answer is big enough, and important enough, that it’s ...

Bacillus thuringiensis (Bt) is an insecticide with unusual properties that make it useful for pest control in certain situations. Bt is a naturally occurring bacterium common in soils throughout the ...

Pollen wafting from bioengineered corn to traditional varieties may be undermining the fight to keep pests from evolving resistance to pesticides, according to a new study. Farmers who plant Bt corn, ...

Planting genetically modified, pest-resistant corn can provide a halo effect — offering protection from insects to nearby corn plants that have not been engineered to kill bugs, scientists said ...

ITHACA, N.Y. -- Genetically modified crops containing two insecticidal proteins in a single plant efficiently kill insects. But when crops engineered with just one of those toxins grow nearby, insects ...

Steady exposure has prompted concern that pests will develop resistance to these proteins, making Bt plants ineffective. Cornell research shows that the combination of natural enemies, such as ...
