Parasitic fly (Cochliomyia hominivorax) whose larvae burrow into living flesh of mammals, causing myiasis; a recurring livestock threat across the Americas.
No evidence-backed relationships are recorded.
University of Kentucky and USDA researchers tracked 21 major hydrocarbon peaks and found mating reshapes screwworm flies' chemical coat, most in females. Fly behavior was not tested, so its value for monitoring and control is still a hypothesis.
Reality
Three livestock associations say ICE operations kept workers home and delayed thousands of cattle shipments, costing millions of dollars in lost revenue. Feed yards holding returned cattle pay first, and beef prices rise only if the absences last.
Reality
USDA's screwworm response now takes its placement orders from habitat and weather models built by its own livestock insects lab in Kerrville, Texas. The agency did not report how accurately those models forecast.
Reality
The screwworm closure is being unwound while more than 40 cases sit inside Texas and New Mexico. Economists say the relief is not in the price; it is in the discretion Washington now holds.
Reality
Sonora logged its first screwworm case days before the Douglas crossing reopens to Mexican cattle. The staged caps return roughly a fifth of pre-ban volume in the opening week.
Reality
The Aug. 24 reopening at Douglas caps Mexican cattle volumes far below the pre-ban flow, and any expansion depends on a clean run at a single crossing.
Reality
The New World screwworm's first US crossing in 60 years shut the border to cattle movements. The sterile-fly plant that is supposed to fix it does not open until April 2027.
Reality
One vector incursion froze cattle movement, then pet transport. Thousands of Texas shelter animals are stuck in place, and shelter directors say euthanasia is the release valve.
