The researchers examined the effects of pollen from a genetically modified maize variant called “Bt corn” on bees. A gene from a soil bacterium had been inserted into the corn that enabled the ...

This new Bt gene, however, did not produce a "high dose" that killed 99.99 percent of all rootworms. Instead, it was what you'd call a "moderate dose," says Tabashnik. He says it's the worst ...

Although almost no genetically enhanced crops were used as recently as 1996, this year one-third of the nation's corn fields are expected to be planted in Bt-enhanced varieties. Bt-enhanced corn was ...

When Blair Hoerbert began farming more than 25 years ago, the notion of genetically engineered crops that could kill insect predators was something found only in the world of science fiction. Last … ...

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 ...

The genetically modified corn plants killed rootworms. "This is a very important discovery, because it shows we can find very efficacious proteins from non-Bt sources," says Tom Greene, a senior ...

Bt corn is corn that has been genetically modified so that it produces proteins from the bacterium Bacillus thuringiensis to control corn borers, corn rootworms and other major pests of corn. The ...

June 6, 2022 — The largest, highest quality analysis of data ever conducted reveals that genetically modified Bt corn has little impact on nontarget insects and other organisms, ...

Finally, Nielsen cautions farmers to be aware that grain buyers who limit or segregate their genetically modified corn grain purchases this fall will have quick test kits available for the detection ...

The genetically modified plants, Bt corn, have had an economic benefit of $6.9 billion during the past 14 years in the five Upper Midwest corn-producing states studied, the researchers concluded.

John Losey thought his Nature paper might attract some attention, but not the media "whirlwind" of "a good 60 calls" that disrupted his life for a few days. Losey, assistant professor of entomology at ...
