En köttätande parasitfluga har återvänt till USA efter 60 år. Det amerikanska jordbruksdepartementet (USDA) bekräftade denna vecka förekomsten av New World screwworm hos en kalv i södra Texas.

New World screwworm utgör ett stort hot mot boskap. Genom att släppa ut steriliserade flugor kan man slå ut en lokal population av insekterna. USA har för närvarande begränsad kapacitet att producera de steriliserade flugor som krävs för sådana insatser. USDA utvärderar nu alternativ för att utöka produktionen. Bekräftelsen markerar den första upptäckten i landet sedan 1960-talet.
