Scientists Study Odor Cues to Combat Northward-Spreading Screwworm Parasite
0
·6 viewsThe New World screwworm, a flesh-eating parasite, is expanding its range northward into the United States, raising urgent concern among researchers. The fly lays its eggs in open wounds, with larvae feeding on the living tissue of animals. Scientists are now investigating the specific foul-smelling chemical signals that attract this species, hoping to identify what draws it to hosts. A key challenge is that existing traps capture related fly species, making it hard to accurately detect the screwworm in particular. Better understanding of its odor preferences could lead to more targeted and effective detection and control strategies.
