Five to seven days after egg hatch (Matlock and Skoda 2009), mature larvae exit the wound and burrow a few centimeters into the ground to pupate (USDA-APHIS 2014a). 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. In its natural state it lives only on the living flesh of mammals and birds. Before its eradication from North and Central America, it caused devastating losses among livestock and wild animals. The New World screwworm, Cochliomyia hominivorax, was eradicated from North America through a multi-national program led by USDA. A single infestation can kill a small animal in a few days and a multiple infestation can lead to the death of a larger animal in as little as a week (Krafsur et al., 1987).The umbilicus of newborns is especially attractive to ovipositing females. As a result of a 45-year area-wide campaign, suppression and eradication have been achieved in the USA, Mexico, Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, The use of the sterile insect technique (SIT) in New World screwworm Cochliomyia hominivorax (Coquerel) eradication programmes has been successfully demonstrated. Currently, this species is known as the “New World Screwworm” due to its endemic occurrence in tropical, subtropical and temperate zones in … The New World screwworm, Cochliomyia hominivorax, is a primary parasite of warm-blooded animals. The results of these investigations were used to establish successful control plans, including the program to eradicate C. hominivorax in the United States, Me- 2004). Cochliomyia hominivorax Biology. The New World Screwworm (NWS, Cochliomyia hominivorax) is an obligate parasite of warm-blooded animals. 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. Cochliomyia hominivorax screwworm larva (left) (photo by J. Kucharski, USDA ARS) and adult (right) (photo by Guillermo Fadul, Screwworm Barrier Maintenance Program in Panama). C. hominivorax is a dipteran of the Calliphoridae order and it had its biology first described by Coquerel, (1858) [12]. 1), have been eradicated from the USA and now have a tenuous hold only in the Yucatan peninsula of Mexico, where control programmes based on massive release of sterile males have recently been initiated. 2. 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. Cochliomyia hominivorax and Dermatobia hominis, be-cause of their great impact on human and animal health on the economies of many countries (Phillips et al. The female lays up to 300 eggs in any break in the skin, and the resulting larvae (screwworms) burrow into surrounding living flesh. The outcomes of screw worm (Cochliomyia hominivorax; larval stages of which feed on the living flesh of their host (livestock)) eradication and control measures enacted in the USA (1957-59, 1962-66), Mexico (1972-91), Guatemala (1988-94), Belize (1988-94), El Salvador (1991-95), Honduras (1991-96), Nicaragua (1992-98), Costa Rica (1995-99), and Panama (1997-2000) are described. Screwworms, Cochliomyia hominivorax (Fig. Cochliomyia hominivorax is an obligate parasite whose larval stage must feed on the tissue of a living warm-blooded animal to complete the life cycle. 1987).
