Bt cotton is resistant to pests, such as lepidopteron, dipterans and coleopterans. Is BT cotton also resistant to other pests as well?
The genes from Bacillus thuringiensis are pest-specific. This means that they are highly effective against a select group of pests but do not harm other insects. As a corollary, Bt cotton is not resistant to other pests. This is, in fact, an advantage from the perspective of maintaining biodiversity in the environment. Beneficial insects are saved from harm because farming of Bt cotton does not need the use of pesticides.
