The insects are exposed to the toxin proteins in transgenic crops throughout the feeding cycle and season, and as a result, the insect populations are under continuous selection pressure. As the toxins are expressed in all parts of the plant, there is a serious threat of rapid development of resistance in insect pests. Toxin production […]

The People’s Republic of China was the first country to commercialize transgenic crops in the early 1990s, with the introduction of a virus resistant tobacco, followed by virus resistant tomato. In 1994, the USA followed when the Calgene Company got the first approval to commercialize a genetically modified tomato ‘Flavr Saver TM’, the delayed ripening […]
Genetic Control of Insect Pests | Pest Management
Article shared by :
Genetic control strategies involve alterations of a targeted pest’s ability to reproduce or the insertion of some deleterious character into a pest population. Genetic control is a form of biological control of pest species which exploits the insect’s mate-seeking expertise to introduce genetic abnormalities (typically, but not necessarily, dominant lethal mutations) into the eggs of […]
