USDA manages the production of the sterile flies. USAID was a major funding source for the UN Food and Agriculture Organization which did the monitoring.
I appreciate you citing the USAID funding but you seem to be trying to prove a point rather than get to the truth. Screwworm detection and prevention was not halted because of the USAID shutdown, USDA is actively working on it, one can see this by going to usda.gov and searching for "screwworm". I really appreciate ajmurmann's edit which acknowledges this.
> Among the GHS projects killed were some dedicated to *monitoring and containing avian flu and New World Screwworm in Central America, monitoring* avian flu outbreaks in Asia and improving the detection of new strains, and efforts to combat swine fever, according to a person familiar with the situation granted anonymity to speak frankly.
you might not have intended to mislead, but the cited source indicates that at least some were defined and thus halted, in partial contradiction to your line "Screwworm detection and prevention was not halted because of the USAID shutdown"
Everything I'm reading says it has been funded by USDA, and in fact funding has been significantly increased during 2025.
