Myiasis is an animal or human disease caused by parasitic dipterous fly larvae feeding on the host's necrotic or living tissue. Colloquialisms for Myiasis include fly-strike and fly-blown. A parasite is an organism that lives in or on the living tissue of a host organism at the expense of it. ...
Suborders Archidiptera Eudiptera Brachycera Diptera are insects in which the hind wings are reduced to halteres. ...
Zumpt describes myiasis as "the infestation of live human and vertebrate animals with dipterous larvae, which at least for a period, feed on the host's dead or living tissue, liquid body substances, or ingested food."
Classifications Two different classifications of myiasis can be adopted: - The classical classification describes the myiasis by the infected area of the host. For example : dermal, sub-dermal, cutaneous, nasopharyngeal, ocular, intestinal/enteric or urogenital.
- Another classification is based on the relationship between the host and the parasite and provides insight into the biology of the fly species causing the myiasis and its likely effect. Thus the myiasis is described as either obligatory, facultative or accidental.
Flies responsible for Myiasis There are three main fly families causing economically important myiasis in livestock and also, occasionally, in humans: Suborders Archidiptera Eudiptera Brachycera Diptera are insects in which the hind wings are reduced to halteres. ...
The adult flies are not parasitic, however when they lay their eggs in open wounds and these hatch into their larval stage (a.k.a. maggots or grubs), the larvae feed on live and/or necrotic tissue causing myiasis to develop. Oestridea Categories: Animal stubs | Flies ...
Subfamilies Calliphorinae Chrysomyiinae The Blowflies are members of the family Calliphoridae of flies (Diptera). ...
Subfamilies Miltogramminae Sarcophaginae Fleshflies, family Sarcophagidae, are insects that are often mistaken for common houseflies, although they are somewhat larger in size. ...
Larvae are the plural of larva, juvenile form of animals with indirect development. ...

Control Methods - Prevention and Treatment The first control method is preventive and aims to eradicate the adult flies before they can cause any damage and is called vector control. The second control method is the treatment once the infestation is present, and concerns the infected animals (or humans). Traditionally in medicine, a vector is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another. ...
Prevention The principal control method of adult populations of myiasis inducing flies involves insecticide applications in the environment where the target livestock is kept. organophosphorus or organochlorine compounds may be used, usually in a spraying formulation. One alternative prevention methods is the SIT (Sterile Insect Technique) where a significant number of artificially reared sterilized (usually through irradiation) male flies are introduced. The male flies compete with wild bred males for females in order to copulate and thus cause females to lay batches of unfertilised eggs which can't develop into the larval stage.

El Salvador successfully demonstrated the sterile insect technique eliminating the malaria causing mosquito, from a region for a period of time. ...
Another prevention method involves removing the environment most favourable to the flies. One example of this is the crutching of sheep, which involves the removal of skin folds between the rear legs, which is a favourable evironment for the larvae. Crutching is the act of removing the skin folds from between the rear legs of a sheep. ...
Treatment This applies once an infection is underway. First the larvae must be eliminated through pressure around the lesion and the use of forceps. Secondly the wound must be cleaned and disinfected. Further control is necessary to avoid further reinfection.
It is also possible to treat livestock with the use of slow release boluses containing ivermectin which can provide long term protection against the larvae development. Ivermectin sold under brand names Stromectol® in the US and Mectizan® in Canada. ...
Sheep may be dipped, which involves drenching the sheep in insecticide to prevent the growth of the larvae. To dip a flag that is being carried means to lower it by turning it forward from an upright position to 45° or horizontal. ...
Use of Myiasitic maggots in Medicine Through the ages maggots have been used in medicine in order to clean out necrotic wounds. Companies exist which produce sterile maggots which may be used to clean wounds and promote healing. (to be finished... ) See drugs, medication, and pharmacology for substances that are used to treat patients. ...
