the corn borer must have or generate heritable variation in resistance to the toxic protein. the resistance corn borers must survive better or reproduce more than nonresistant corn borers
The Bt gene produces a soil-inhabiting bacteria. This bacteria is known to be made into insecticides and kills insects that eat plants with the Bt genes.
To make Bt corn, a gene is taken from a bacterium called Bacillus thuringiensis. The gene produces a protein that kills corn borer larvae, so growers can use Bt corn as an alternative to spraying insecticides.
