GM Crops Increase Biodiversity

Widespread adoption of Bt cotton and insecticide decrease promotes biocontrol services

Over the past 16 years, vast plantings of transgenic crops producing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) have helped to control several major insect pests1, 2, 3, 4, 5 and reduce the need for insecticide sprays1, 5, 6.

Because broad-spectrum insecticides kill arthropod natural enemies that provide biological control of pests, the decrease in use of insecticide sprays associated with Bt crops could enhance biocontrol services7, 8, 9, 10, 11, 12.
