The primary screwworm, Cochliomyia hominivorax (Coquerel) (Figure 1), also known as the New World screwworm, occurred in several areas of the southern United States before eradication efforts began in the 1950s (Krafsur et al. Monitoring adult populations of the screwworm (Diptera: Calliphoridae) with feeding stations baited with liver. Cochliomyia hominivorax (Coquerel) is endemic to the Western Hemisphere, with the exception of Chile., although it has been eradicated from significant parts of its range.

C. hominivorax adults are approximately 2-3 times the size of a house fly. Baumhover AH, 1963. The sterile males, released in numbers far exceeding the normal population levels, competed with fertile males to mate with females. Identification of the larvae is based largely on the presence or absence of internal breathing tubes and requires a trained entomology specialist for confirmation (Figure 3). Detailed descriptions of the life stages of C. hominivorax are presented in Laake et al. As long as populations of C. hominivorax exist in the Western Hemisphere, modern travel conveyances, especially aircraft, make the introduction of C. hominivorax continents away from the original source of infestation a real possibility. Although naturally occurring in relatively low numbers compared with other insect species, C. hominivorax has been introduced and spread into non-endemic and eradicated areas via movement of infested hosts, including humans. 789 pp. 2005. 1947.
