USDA's Glow-in-the-Dark Flies Battle Mexican Screwworm Spread
The USDA is deploying glow-in-the-dark, sterile flies in Mexico and southern Texas to prevent the spread of parasitic screwworms, which threaten livestock. With recent infestations reported in Tamaulipas, the agency plans to create a 'buffer zone' near the U.S. border and boost sterile fly production efforts.
The U.S. Department of Agriculture is taking innovative measures to prevent the spread of New World screwworms by releasing glow-in-the-dark, sterile flies in Mexico and southern Texas. This strategic move aims to combat an increase in infestations that pose significant threats to livestock.
Recent reports revealed 20 screwworm infestations since late December in Tamaulipas, Mexico, prompting the USDA to establish a 'buffer zone' 50 miles into Texas. The agency plans to significantly increase the production of sterile flies, aiming to contain the pest and reduce its impact on the beef market.
To distinguish sterile flies from the harmful wild populations, fluorescent dye will be applied, allowing them to glow under UV light. The USDA's swift actions align with Mexico’s technical proposals, as both countries strive to protect their livestock industries from the dreaded screwworm.
