New World Screwworm Parasite Spreads in US: Smell May Help

A dangerous parasite, the New World screwworm, is spreading in the US, prompting urgent research into its attractants. Scientists are focusing on foul-smelling chemical signals that lure this flesh-eating fly, which lays eggs in open wounds. Current traps are ineffective, attracting related species instead, making detection challenging. Identifying the preferred odors of this parasite could enhance detection and control methods, ensuring better protection for livestock and wildlife.
