GM, insect resistant Bt cotton and 11 billion sterile moths destroy pink bollworm from the US and Mexico

Southwestern United States and Northern Mexico coordinated a program in which they included releases of billions of sterile pink bollworm moths from airplanes and planting of cotton engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis (Bt). An analysis of computer simulations and 21 [years] of field data from Arizona demonstrate that the transgenic Bt cotton and sterile insect releases interacted synergistically to reduce the pest’s population size.

In Arizona, the program started in 2006 and decreased the pest’s estimated statewide population size from over 2 billion in 2005 to zero in 2013. The removal of this pest saved farmers in the United States $192 million from 2014 to 2019.
