Since 1996, crop plants genetically modified to produce bacterial proteins that are toxic to certain insects, yet safe for people, have been planted on more than 200 million hectares worldwide. The ...

In 2016, farmers worldwide planted more than 240 million acres (98 million hectares) of genetically modified corn, cotton and soybeans that produce insect-killing proteins from the bacterium Bacillus ...

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 ...

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 ...

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.

The current jumble of terms about insects and weeds that are resistant to pesticides has fostered confusion among scientists. To address this, entomologists have updated definitions for 50 key terms ...

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 ...

As Washington residents weigh the pros and cons of labeling genetically engineered foods, one question on many minds is whether current GE crops have helped or harmed the environment. A panel of ...

ST. PAUL, Minn. — While European corn borer once caused substantial yield losses and economic damage for corn growers across the United States, the pest has not been a major cause of concern since Bt ...

Widespread planting of corn hybrids designed to combat corn rootworm, the crop's most damaging pest in the Corn Belt, is reducing both the technology's effectiveness and some farmers' profits. The ...

Pest resistance to genetically engineered crops Bt crops is evolving faster now than before, researchers show in the most comprehensive study to date. But as expected from evolutionary theory, ...
