In 2015, Oxitec developed GM-diamondback moths which produce non-viable female larvae to control populations able to develop resistance to insecticides. The GM-insects were initially placed in cages for field trials. Earlier, the moth was the first crop pest to evolve resistance to DDT [27] and eventually became resistant to 45 other ...
Core says that crops that are not fortified through genetic modification often have to be sprayed with more pesticides, in order to ensure a more fruitful yield — otherwise, bugs and diseases ...
Delta endotoxins (δ-endotoxins) are a family of pore-forming toxins produced by Bacillus thuringiensis species of bacteria. They are useful for their insecticidal action and are the primary toxin produced by the genetically modified (GM) Bt maize/corn and other GM crops.
This has led to their use as insecticides, and more recently to genetically modified crops using Bt genes, such as Bt corn. [4] Many crystal-producing Bt strains, though, do not have insecticidal properties. [5] The subspecies israelensis is commonly used for control of mosquitoes [6] and of fungus gnats. [7]
The U.S. GM cotton crop was 4.0 million hectares, the second largest area in the world, followed by China with 3.9 million hectares and Pakistan with 2.6 million hectares. [6] By 2014, 96% of cotton grown in the United States was genetically modified [7] and 95% of cotton grown in India was GM. [8] India is the largest producer of cotton, and ...
GM crops have been the source of international trade disputes and tensions within food-exporting nations over whether introduction of genetically modified crops would endanger exports to other countries. [434] In Canada in 2010, flax exports to Europe were rejected when traces of an experimental GM flax were found in shipments. [435]
Other GM crops grown in 2014 include Alfalfa (862 000 ha), sugar beet (494 000 ha) and papaya (7 475 ha). In Bangladesh a genetically modified eggplant was grown commercially for the first time on 12 ha. [6] The majority of GM crops have been modified to be resistant to selected herbicides, usually a glyphosate or glufosinate based one.
Genetically modified maize is a genetically modified crop. Specific maize strains have been genetically engineered to express agriculturally-desirable traits, including resistance to pests and to herbicides. Maize strains with both traits are now in use in multiple countries.
