Their activity can draw in more adult flies, including those of other blow fly species, that can deposit more eggs. In these countries, C. hominivorax has been controlled for several decades almost exclusively by insecticides, particularly organophosphate (OP)‐based compounds, whose target site is the enzyme acetylcholinesterase. Cochliomyia is a genus in the family Calliphoridae, known as blowflies, in the order Diptera. The screwworm was eradicated via the sterile insect release method in which flies sterilized by exposure to gamma radiation were liberated into the environment from aircraft. Due to its distribution and abundance, the secondary screwworm, Cochliomyia macellaria, is of particular importance in the United States. As of the publication of this document, the USDA is preparing to release sterilized male primary screwworms in the area of the current outbreak to eradicate the infestation. (1936). Influence of habitat, season, and attractant on adult behavior of the screwworm (Diptera: Calliphoridae) in a tropical dry zone in Costa Rica. are common predators of larvae that have exited wounds to pupate and have been observed pulling larvae from wounds (J Welch, unpublished data). Eradication of the flies is occurring in the affected area, and an animal quarantine and Animal Health Check Station is in effect for the area (see FDACS Proclamation for details). Clinical Infectious Diseases, 43(6):e57-e59. Wounds that are not properly healing or that are draining excessively should be inspected for larvae.

Adult screwworm, Cochliomyia hominivorax (Coquerel). The New World screwworm1 (NWS), Cochliomyia hominivorax (Coquerel), and the Old World screwworm1 (OWS), Chrysomya bezziana Villeneuve, are both obligate parasites of mammals, including humans, during their larval stages. Insects in the family Calliphoridae are generally referred to as blow flies or bottle flies. 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). Trop. The flies that cause myiasis in man. The otitis was due to numerous larvae of C. hominivorax. The spiracles with three slit-like openings are almost completely surrounded by heavily sclerotized peritremes, but which appear incomplete ventrally. Infestation generally occurs at the site of a recent, existing wound, such as a scrape, lesion or even tick feeding site, but also from castration, dehorning, branding, ear tagging, or shearing.

If you suspect screwworm (the presence of flesh-eating larvae is the surest sign), collect the larvae in alcohol and give them to your veterinarian immediately. Eggs are generally laid on or near the edges of wounds but may also be laid on or near host body orifices with purulent discharge. They are approximately 10.2 mm and 4.3 mm in length and width, respectively. Several traps exist for monitoring primary screwworm adults; these are generally sticky traps baited with an attractant lure (swormlure-4) (Broce et al. CABI is a registered EU trademark. 1948.

The adult primary screwworm, Cochliomyia hominivorax is a metallic blue fly with three stripes that run down the top (dorsal surface) of the fly just behind the head, and orange eyes (Figure 1). The current distribution of Cochliomyia hominivorax is primarily south of the Darién gap in southern Panama, including much of South America, and on a few Caribbean islands, notably Jamaica and Cuba (Welch 2016). The brood stock is taken to the adult fly colony (78°F [25.6°C], 70 percent RH), where 6 litres of pupae are placed in each adult-fly cage supplied with water, 1.6 litres of honey and 2.4 kg of honey-meat mixture.

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 ideal environmental conditions, primary screwworms can complete their life cycle in 24 days (Laake et al. Baumhover AH, 1963. Cochliomyia hominivorax, the New World screwworm, is indiscriminant in its choice of hosts, and cats will be infested by this fly.The female lays batches of eggs in rows on the edge of any small would in the skin, and after about one-half to one-day, the eggs hatch and the larvae crawl into the would site. Predation by spiders on ground-released screwworm flies, Cochliomyia hominivorax (Diptera: Calliphoridae) in a mountainous area of southern Mexico. Once larvae are fully formed, they drop to the ground where they pupate in the leaf litter or upper soil levels. A barrier zone is maintained in Panama using sterile flies and field operations to prevent immigration of C. hominivorax into eradicated areas.

Using sterile male flies, the primary screwworm was eradicated in Florida in 1960. The screwworm was not eradicated from the rest of the United States until 1983 because of ongoing incursions of flies from Mexico (Novy 1991).

Key deer are an endangered species that have been found only on the Florida Keys, and several have died or been euthanized due to the 2016 screwworm infestations (FDACS 2016). Prior to the 1950s and 60s, primary screwworms were a major economic burden to the production and treatment of livestock in the southwestern United States and Florida. Dear (1985) presents an explanation of the taxonomy and nomenclature of C. hominivorax and other members of the Chrysomyini. Studies on the Higher Diptera of 134 Medical and Veterinary Importance. The distribution of tsetse fly in Africa overlaps that of C. bezziana to a considerable extent (see Figure 5), and historically cattle are not maintained in areas infested by tsetse.

There are no data to suggest that natural enemies are important to the population dynamics of C. hominivorax. Eggs are laid in a parallel pattern in layers glued together to form a mass which gives them the appearance of a shingled roof. Other insects, birds, frogs, lizards and spiders feed on adult C. hominivorax.Welch (1993) describes the predation of ground-released sterile C. hominivorax flies by spiders. Impact on biodiversity is low, but may become more important in localized areas during conditions which promote the increase of C. hominivorax populations. These traps are often used to monitor for the flies to ensure that sterile insect programs are working to provide area-wide control of screwworms (Vreysen et al. C. hominivorax was distributed throughout the northern South America, Central America, Caribbean Islands, and the United States prior to the use of the sterile insect technique, after which it was eliminated from the U.S. and Mexico.
