No. Unlike most other fly species, the screw worm flies only lay their eggs in wounds on living hosts. They do not breed in dead carcasses, manure, rotting vegetation.
LuckyP, from what I remember from ag class in the mid 60s, the larvae of a screw worm fly and a blow fly were indistinguishable except under a microscope.

Still breeding and releasing them in um...our country too.
[H2]The United States and Mexico Agree to Fight the Screwworm Together[/H2]
By 1963, researchers discovered that screwworm flies could fly distances of up to 180 miles. This meant that none of the southwestern states could be free of screwworms until the pests were eradicated in Mexico. In 1965, following an outbreak in the Southwest, Mexican and U.S. livestock producers signed a declaration asking for the establishment of a joint program for the eradication of the screwworm from the states on either side of the Mexico-U.S. border.
[H2]The United States Officially Declared Free of Screwworms[/H2]
The United States was declared officially free of indigenous screwworms in 1966. By that year the Mission facility was producing up to 150 million sterile flies per week. U.S. livestock was still vulnerable to reinfestation from screwworms migrating from areas in Mexico that had not been eradicated.
[H2]The Barrier Zone Between the United States and Mexico[/H2]
Once the United States was free of self-sustaining screwworm populations, a barrier zone was established between Mexico and the United States by releasing sterile male flies in northern Mexico, primarily in the border areas. Releasing the flies deterred the buildup of the natural screwworm population along the Mexico and United States border.
