Southeast Researchers Join USDA Screwworm Fight

Back in January, USDA launched its New World Screwworm Grand Challenge, a nationwide effort to accelerate new tools for detection, control, and eradication of the pest. Now, as New World screwworm cases in the United States have reached double digits, the agency is announcing where much of that funding will go.

USDA says 40 projects will receive a combined total of about $105 million through the initiative. The agency also notes that work is already underway on two additional USDA-funded projects that are part of the Grand Challenge.

While New World screwworm is often associated with cattle, recent U.S. cases have also involved sheep, goats, and a dog, highlighting the importance of rapid detection and response.

Several southeastern institutions are among those receiving support. The University of Florida is evaluating U.S.-made X-ray irradiators for sterilizing screwworm pupae, while another University of Florida project will study fly- and wound-associated microbiomes to develop new attractants for detection and monitoring. Auburn University received funding for work focused on sterile insect performance and risk forecasting.

The National Cattlemen's Beef Association is also receiving support to develop producer identification training modules and public relations resources related to New World screwworm.
