cochliomyia hominivorax larvae

Screwworm control and eradication in the southern United States of America. 637 pp. Campaigns against the flies continue in Mexico, Nicaragua, Costa Rica, Panama, and Jamaica with financial assistance from the United States Department of Agriculture, which tries to push back the parasite beyond the narrow and easily controlled Isthmus of Panama. The patient recovered satisfactorily after treatment with ivermectin and amoxicillin. … Cochliomyia hominovorax is the primary screwworm fly in the New World. The screwworm was not eradicated from the rest of the United States until 1983 because of ongoing incursions of flies from Mexico (Novy 1991). Screwworms can infest all types of mammals and other warm-blooded animals, including livestock, wildlife, pets and even humans, although they are rarely found in birds. 1948. Sterile Insect Technique: Principles and Practice in Area-wide Integrated Pest Management. This species’ larvae are renowned for eating and infesting the flesh of living organisms, primarily warm-blooded animals such as cattle and other livestock. It is present in the New World tropics. Because females only mate once, any fly that mated with a sterile male will be unable to produce offspring which results in the eventual elimination of the fly. Is a pet or other animal exhibiting signs of screwworms? A Key deer (Odocoileus virginianus clavium) killed by primary screwworm, Cochliomyia hominivorax (Coquerel), with other blow fly adults visiting the carcass. Such wounds can be as small as a tick bite. Taboada O. The larvae were sent to the Connecticut Agricultural Experiment Station and were identified as the New World screwworm. McAlpine JF. While the maggots of many fly species eat dead flesh, and may occasionally infest an old and putrid wound, screw-worm maggots are unusual because they attack healthy tissue. 1987). Hall MJR. Screwworms, Cochliomyia hominivorax Coquerel (Diptera: Calliphoridae), cause myiasis in cattle, wildlife and humans. Although considered eradicated throughout most of North America, active infestations still occur in Jamaica, Cuba, and across South America. Screw-worm females lay 250–500 eggs in the exposed flesh of warm-blooded animals, including humans, such as in wounds and the navels of newborn animals. 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). Introduction. This infection apparently was … Screwworm flies as agents of wound myiasis. Infestation of a live vertebrate animal by a maggot is technically called myiasis. 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). Photograph by Heather Stockdale Walden, University of Florida. World Animal Review: Special issue: New World screwworm response to an emergency. Primary screwworm infestations begin when an adult female fly deposits eggs in an existing wound on an animal. They will assist animal owners in the treatment of infested animals and remove flies from the vicinity. Area-wide Control of Insect Pests: From Research to Field Implementation. We present a case of myiasis caused by the New World screwworm fly (Cochliomyia hominivorax) in a pin site of a chronic nonhealed wound 12 years after the intervention. Keywords: Myiasis, Cochliomyia hominivorax, Ivermectin, Diptera Accepted on March 18, 2020 Introduction Myiasis is a parasitosis, which is determined by the invasion of certain fly larvae of the order Diptera in human tissues or from tissues of other vertebrates such as sheep and goats [1]. From the Greek kochlias (snail with a spiral shell) + myia (fly) and the Latin hominis (man) + vorax (consuming), Cochliomyia hominivorax, or the New World screw-worm fly (formerly Callitroga (Greek kallos, (beautiful), + trogein, (to gnaw), americana), was first described by French entomologist Charles Coquerel in 1858. These non-screwworm blow flies may lay eggs in the same wound and thus one may see other types of blow fly adults and their larvae on the animals, particularly as the animal’s health declines. Typical insecticide suppression of the primary screwworm is not as effective as with other insect pests. This insect has been eradicated from the United States, Mexico and most of the Central America, using sterile insect technology. Williams RE, Hall RD, Broce AB, Scholl PJ (Eds.). Outside of the United States, introductions or re-introductions, followed by eradication, have occurred in Aruba, Australia, Curacao, Libya, Mexico, and Panama (Welch 2016). 1936. Cochliomyia hominivorax, the New World screw-worm fly, or screw-worm for short, is a species of parasitic fly that is well known for the way in which its larvae (maggots) eat the living tissue of warm-blooded animals. The New World screwworm fly, Cochliomyia hominivorax, is an obligate ectoparasite and will infest almost all warm-blooded livestock, wildlife and humans; it is unable to breed in carrion.These bluish to bluish-green flies have three prominent longitudinal black stripes on the thorax. Due to the wide success of this program and in cooperation with our southern neighbors, the primary screwworm has been eradicated from North America down to a zone south of the Panama Canal. For a detailed distribution map please refer to the CABI Screwworm Datasheet. Human cases are not common but may be seen in regions where livestock is tended. A control program is managed cooperatively between the governments of the United States and … Larvae (Figure 2) found in an animal wound can reach 17 mm in length (2/3 of an inch). USDA Miscellaneous Publication No. 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). World Animal Review: Special issue: New World screwworm response to an emergency. The larvae hatch and burrow into the surrounding tissue as they feed. The most important insect pest of livestock in the Americas, it was established in 1988 for the first … Wounds that are not treated can become life threatening in 7 to 14 days. After removal, infestations often are treated topically with a pesticide to kill any larvae that may not have been removed and to reduce the likelihood of reinfestation. Cochliomyia hominivorax Biology. 175 pp. 2009. The pupae reach the adult stage about seven days later. Because pets can become infested, it is important that owners watch any wounds that do not heal properly. Most significant among the latter group is the New World screwworm, Cochliomyia hominivorax (Coquerel). 1991. In ideal environmental conditions, primary screwworms can complete their life cycle in 24 days (Laake et al. Any suspected or discovered case of larvae in a live host must be reported to the Florida Department of Agriculture and Consumer Services. C. hominivorax is a dipteran of the Calliphoridae order and it had its biology first described by Coquerel, (1858) [12]. The following information was provided by FDACS on 04 Oct. 2016: Residents who have warm-blooded animals (dogs, cats, livestock, horses, birds, etc.) Vreysen MJB, Robinson AS, Hendrichs J. The larvae should be removed with forceps and the wound cleaned. 2007). 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). Samantha Gibbs, U.S. Such pigmentation is unique to this species among those encountered in wound myiasis and is a major character for identification keys. Also, larvae are laid in multiple batches, with mature flies attracted back by a scent given off by maturing larvae. Historical Management and Eradication Novy JE. This article aimed to report a case of myiasis caused by Cochliomyia hominivorax in the palate of a patient with primary progressive aphasia, which was successfully treated through mechanical removal of larvae plus administration of ivermectin. Fish and Wildlife Service. 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. There are five species of Cochliomyia but only one species of screw-worm fly in the genus; there is also a single Old World species in a different genus (Chrysomya bezziana). Email a photo to AgVeterinarians@FreshFromFlorida.com and FDACS veterinarians will review the photo and respond to you. Figure 3. Although con… Wild and captive-raised deer also can be affected. Human infestation is rare but can be fatal because larvae penetrate deep tissue.

This page was last edited on 9 July 2020, at 11:51. 1977). It is exceedingly important to report any infestations to Florida Department of Agriculture and Consumer Services. The United States officially eradicated the screw-worm in 1982 using the sterile insect technique. Elsevier, London, UK. 1987). Livestock Entomology. Cochliomyia hominivorax is endemic to the Western Hemisphere and occurs in tropical, … Note the dark stripes across the backline (thorax) of the fly behind the head. There are five species of Cochliomyia but only one species of screw-worm fly in the genus; there is also a single Old World species in a different genus (Chrysomya bezziana). Dissection of internal darkened breathing tubes (trachea) from the larva of a primary screwworm, Cochliomyia hominivorax (Coquerel). . This feature is used to differentiate primary screwworm larvae from secondary screwworm larvae. All individuals headed north from Key Largo with warm-blooded animals are required to stop at the animal inspection facility that has been established to prevent the spread of the infestation. The early stages of an infestation are difficult to detect (Figure 4). Samantha Gibbs, U.S. 789 pp. In conventional treatments of myiasis, chemo-synthetic insecticides have been employed directly on larvae present in the wounds. Fish and Wildlife Service. The mass rearing of the screwworm fly, Cochliomyia hominivorax (Diptera: Calliphoridae), for programs that integrate the Sterile Insect Technique in the Americas is part of one of the largest insect mass rearing programs in the world. The primary screwworm is not capable of overwintering in areas that experience low temperatures or extended dry periods. Their larvae infest warm-blooded vertebrates and feed on host’s tissues, resulting in severe industry losses. 2. The primary screwworm can quickly devastate flocks or herds and, in the past, has cost the U.S. livestock industry billions of dollars. Cochliomyia hominivorax was historically found throughout the southern United States, Central America, and the northern countries of South America. In addition, mucous membranes and antlers that are shedding velvet are potential sites of infection. Adult primary screwworms, like all blow flies, do not bite animals. An agricultural emergency has been declared for Monroe County. Medical and Veterinary Entomology (2nd ed.). 2007. Medical Entomology. 631. Figure 5. Today, screwworm has been eradicated in the United States, Mexico, Central America, and several Caribbean islands. Cochliomyia hominivorax and Lucilia cuprina are major pests of livestock.

Female screw-worm flies mate four to five days after hatching. Most 787 pp. Their damage is done through the feeding of the larvae on the wounds of living animals. Larvae. Management of the Current Outbreak Screwworms are endemic to the Western Hemisphere and pose a serious threat to livestock, wildlife, pets, and humans (Williams et al. 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. Laake EW, Cushing EC, Parish HE. These eggs hatch, and the larvae feed on the healthy tissue, causing the wound to enlarge. 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. The center stripe begins partway down the Their activity can draw in more adult flies, including those of other blow fly species, that can deposit more eggs. fly (Diptera). Should the wound be disturbed during this time, the larvae burrow or "screw" deeper into the flesh, thus the insect's name. After laying eggs on the skin surface, usually on the border of wounds, the eggs hatch and larvae penetrate in the tissue causing larger and deeper … Screwworms are endemic to the Western Hemisphere and pose a serious threat to livestock, wildlife, pets, and humans (Williams et al.

Oct: 08-17. The Latin name of this bug is Cochliomyia hominivorax. Interestingly, most screwworm females only mate once, making them an ideal candidate for the sterile insect technique described below. Several traps exist for monitoring primary screwworm adults; these are generally sticky traps baited with an attractant lure (swormlure-4) (Broce et al. As they are serious pests, considerable effort has been made to develop genomic resources and functional tools aiming to improve their management and control. 2016. The blow flies of North America, Thomas Say Foundation Publication vol. In the late 1950s, the USDA began implementing an eradication strategy based on releasing sterile male flies in the environment along with reducing infestations by continuous animal monitoring. The Cochliomyia hominivorax larvae have distinctly pigmented tracheal trunks. 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. Adults are roughly 2 to 3 times the size of a house fly. In total, 55 larvae were removed from the wound and identified as Cochliomyia hominivorax. This study reports a 49-year-old tracheostomized man undergoing chemotherapy treatment who was parasitized in the hospital in São Gonçalo, Rio de Janeiro, Brazil, by larvae of the screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) in the thoracic cavity. Cochliomyia hominivorax, or the Primary screwworm, is a parasitic species belonging to the Calliphoridae family of flies. Figure 2. The maggots are capable of causing severe tissue damage or even death to the host. Cochliomyia is commonly referred to as the New World screwworm flies, as distinct from Old World screwworm flies. In newborn mammals, it often infects the site of the healing umbilical cord. Adult flies will emerge from the pupae 7 to 10 days later and begin the cycle again. Healing was uneventful in the six cases presented, and no undesirable reactions were observed throughout the period of treatment.

A literature search was performed in Pubmed, Medline, Lilacs and Google Scholar, with 64 cases of myasis by C. hominivorax … 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. Female, dorsal view. About three to seven days after hatching, the larvae fall to the ground to pupate. James MT. The laboratory identified the larvae as those of the fly Cochliomyia hominivorax. Figure 1. 2007). Publishers. The sterile males, released in numbers far exceeding the normal population levels, competed with fertile males to mate with females. However, a 2016 outbreak occurred in Monroe County, Florida. Once larvae are fully formed, they drop to the ground where they pupate in the leaf litter or upper soil levels. Naval Medical School 1967. Images of Cochliomyia hominivorax and Cochliomyia macellaria eggs, larvae, and adult flies. 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.

Along with other control measures, the release of sterile insects, known as the sterile insect technique or SIT, was used successfully in eradication efforts in North America (Vyrsen et al. Larval primary screwworm, Cochliomyia hominivorax (Coquerel). The center stripe begins partway down the backside and appears shorter than the outer stripes. 1985. 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. It may involve species of fly whose larvae feed only on diseased and dead tissue or, more seriously, it may involve species that are obligate parasites and feed on the living tissues of their hosts. Canada Communication Group, Ottawa, Canada. The New World Screwworm fly (NWS), Cochliomyia hominivorax, is an ectoparasite of warm-blooded animals and a major pest of livestock in parts of South America and the Caribbean where it remains endemic. 4. Infestation of a live vertebrate animal by a maggot is technically called myiasis. Write "Please review this photo for screwworm" in the subject line. Oct: 18-27. The entire lifecycle is around 20 days. Infested animals should not be moved to ensure that flies are not moved to uninfested areas. U.S. Government Printing Office, Washington D.C. 395 pp. The flies that cause myiasis in man. 1987. Biology, of the primary screwworm fly. Small lesions on a Key deer (Odocoileus virginianus clavium) killed by primary screwworm, Cochliomyia hominivorax (Coquerel), with other blow fly adults visiting the carcass. Handout picture taken on June 9, 2010 of a scientist showing sterile screw-worm flies (Cochliomyia hominivorax) larvae, at a laboratory in Pacora, eastern Panama City. [1] The screw-worm was eradicated in Guatemala and Belize in 1994, El Salvador in 1995, and Honduras in 1996. The New World screwworm (NWS), Cochliomyia hominivorax, causes myiasis in man and warm‐blooded animals.It is a Neotropical species, and its former geographical distribution ranged from the southern U.S.A. to northern Argentina and throughout the Caribbean basin. As of October 04, 2016, the current primary screwworm outbreak is confined to Monroe County on Big Pine Key. This fly may easily be confused with the secondary screwworm, which also has three lines; however, all three lines begin at the same point behind the head on the secondary screwworm. In October of 2016, the USDA-APHIS (United States Department of Agriculture-Animal and Plant Health Inspection Service) confirmed the presence of primary screwworm in Key deer (Odocoileus virginianus clavium) on Big Pine Key in Florida. 631. 2005.

A wind oriented trap for screwworm flies. The larvae of both Cochliomyia macellaria and Cochliomyia hominivorax have a cylindrical body tapering anteriorly with 10 or more robust spines around the spiracular area, incomplete peritreme, an indistinct or absent button, and bands of small spines on each segment. Wounds that are not properly healing or that are draining excessively should be inspected for larvae. Journal of Economic Entomology 70: 413-416. USDA confirms New World screwworm cases in Big Pine Key, Screwworm eradication in North and Central America. A second screwworm species, the secondary screwworm, Cochliomyia macellaria (Fabricius) also is found in Florida; however, this species only infests dead animals or animals already harboring primary screwworm infestations (Byrd 1998). Cochliomyia hominivorax, the New World screw-worm fly, or screw-worm for short, is a species of parasitic fly that is well known for the way in which its larvae (maggots) eat the living tissue of warm-blooded animals. Your veterinarian will submit them to the USDA’s National Veterinary Services Laboratory for identification. The most mature larvae develop spines that protrude from the body and wrap around in a spiral, hence the name screwworm (Hall 1991). A single adult female can lay as many as 350 eggs, but not all eggs are deposited in a single wound. James, Maurice T. (1947) The Flies That Cause Myiasis in Man. It is present in the New World tropics. 1947. A reported case will not result in herd depopulation, but will allow animal health officials to take steps on your ranch to help you protect your herd. At this time, the outbreak in the Florida Keys is considered to be confined and under quarantine (FDACS 2016). In North and Central America it was eradicated using the Sterile Insect Technique (SIT). Therefore, appropriate treatment is necessary. A female can lay up to 3,000 eggs and fly up to 200 km (120 mi) during her life. Four species are 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). United States Department of Agriculture Miscellaneous Publication No. Cochliomyia hominivorax larvae can be identified by the presence of dark pigmentation of the dorsal tracheal trunks extending forward from the twelfth segment to the tenth or ninth.Other species have less marked pigmentation of the dorsal tracheal trunks. Photograph by Judy Gallagher. Larvae may not be apparent and a veterinarian should be consulted in such situations. Both species are in the subfamily Chrysomyinae of the family Calliphoridae of the order Diptera (true flies). We use secondary screwworms in our laboratory for preliminary experiments as a model for the primary screwworm, Cochliomyia hominivorax (Coquerel), which has been eradicated from the United States.
