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 ...

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.

Since 1996, crop plants genetically modified to produce bacterial proteins that are toxic to certain insects, ... Field-Evolved Insect Resistance to Bt Crops: Definition, Theory, and Data. J.

Global status of insect resistance to Bt crops. ... Next-generation transgenic cotton: pyramiding RNAi and Bt counters insect resistance. Plant Biotechnol. J. 15, 1204–1213 (2017).

IRM strategies can do much to delay resistance to Bt plants. However, the most effective use of Bt crops will be as a component of overall IPM programs. For example, the use of Bt crops in ...

Tma12 binds to the chitin polymers that are a major component of insects’ exoskeletons. After isolating the gene that encodes Tma12, the authors created a transgenic cotton plant that expressed it.

There is evidence that plants and insects interact through sound, researchers at Tel Aviv University said on Tuesday, opening ...

(Beyond Pesticides, November 21, 2014) Researchers of a new study published on Monday find increased resistance in the fall armyworm to Bacillus thuringiensis (Bt)-incorporated genetically engineered ...

Right to Know (USRTK) explains in its coverage of a 2016 independent research study on the subject, “Crops engineered with Bt genes express specific proteins (known as Cry proteins) that make the ...

There are other cases — in the Chinese struggle with the cotton bollworm, for instance — where insect-resistant crops have not even led to a 25 percent drop in insecticides.

Protease inhibitors are a promising strategy for enhancing herbivore resistance in plants, which is crucial for addressing the significant yield losses in crops such as tea plants due to insect ...

To ease fears that widespread use of Bt crops will promote insect resistance, EPA already requires that crops deliver a high dose of Bt and that growers plant Bt-free refuges for insects.
