Venom is associated with being harmful, but red imported fire ants are using their venom for its medicinal benefits by sharing the toxic substance with their nestmates, according to a study published in the Journal of Insect Physiology. Agricultural Research Service (ARS) scientists from the agency's Biological Control of Pests Research Unit and Southern Insect Management Research Unit in Stoneville, Mississippi, discovered a new way that fire ants use their venom to prevent diseases in their colonies.

ARS researchers use biocontrol methods to manage fire ant populations.

Fire ants cause significant harm not only to humans, but to the food we grow? Imported fire ants have invaded about 350 million acres in the U.S., and they cause approximately $8 billion in economic damages per year.

Learn more about what’s happening with this invasive species that has spread throughout the southern U.S., and what ARS is doing about it, as the Office of Communications launches a week-long fire ant campaign (June 22-28, 2024). ARS will feature videos, articles, and interviews with our scientists who are leading the fight against these tiny invaders.

ARS scientists are using a unique receptor interference technology that they have developed to target fire ants. The technology is environmentally friendly and can also be directed at other existing or emerging invasive pests to provide timely, cost-efficient pest control.
