Shelby Jo Weidenkopf Daniel A. Grear Sarah Timbie 2026 <p>The New World screwworm (<i>Cochliomyia hominivorax</i>; NWS) is a parasitic blowfly that lays its eggs in open wounds of live, warm- blooded animals including livestock, wildlife, and potentially humans. The larvae consume living animal tissue, and if untreated, the infestation can lead to death. Although NWS was eradicated in the United States in 1966, it has been moving northward from its endemic range in South America during the past decade and could seriously threaten the health of U.S. wildlife populations, making detection, treatment, and surveillance of the disease far more difficult across this multi- sector disease system.<br>As the likelihood of NWS reintroduction to the United States increases, veterinarians, wildlife managers, and conservation specialists need to be informed and prepared to respond. The existing knowledge about NWS interactions with wildlife hosts is lacking, especially regarding North American species where the NWS has been eradicated for more than 50 years. To address this knowledge gap, we compiled an annotated bibliography that consolidates key information from the existing literature on NWS infestation in wild animals.</p> application/pdf 10.3133/ofr20261006 en U.S. Geological Survey Annotated bibliography of scientific research on new world screwworm (<i>Cochliomyia hominivorax</i>) myiasis in wildlife reports
