What is it about?
Teamwork between farmers and scientists helped to eradicate the pink bollworm, one of the world’s most damaging crop pests, from the United States. A coordinated, multitactic program achieved this success a century after the pest invaded both countries. Tactics included releases of 11 billion sterile pink bollworm moths from airplanes and planting of genetically engineered cotton that produces insect-killing bacterial proteins.

Why is it important?
Eradicating the pink bollworm ended the damage this pest caused to cotton in the US and the insecticide sprays used to control it. This saved farmers $192 million from 2014 to 2019 and yielded environmental and health benefits. This exemplifies how science and teamwork can effectively combat invasive organisms.
