The adult flies most commonly concerned in myiasis belong either to the Muscidae (house fly) or the Oestridae (bot fly) families. Because the larvae develop in decaying organic material, Myasis resulting from flies, which contains the domestic home fly, is considered accidental in man. By comparison, this bot fly’s creatures are parasites of the intestinal tract of mammals or tissues, including man. In this way, they need to be considered parasites that were true.
Flies have general morphology of pests. They have 1 set of wings, the next set being rudimentary knobs called halters. Venation, the position and markers of the wings are important in species identification, Flies have three pairs of jointed legs that end in pads which may secrete a sticky substance or in claws. The mind possesses a set of compound eyes that might or might not meet from the mid-line and a pair of antennae that are jointed in various ways depending upon the species. The mouth parts of this flies are highly improved; skin penetration is effected through saw-like or file-like alterations of the mandible or maxilla. In the female, the terminal segment of the abdomen includes the ovipositors.
Flies complete their life cycle through four phases: Ovum, larva, pupa, and adult by metamorphosis. Flies procreate through the creation of ova; some species are viviparous. Man can get infected directly by fly larva, known as maggots, even though sucking flies spread diseases just by mechanical methods. Myiasis is the expression. Numerous tissues or organs may be involved, including the skin and wounds, the intestine, the urinary tract atria, ears and eyes. Their ova may be deposited by flies directly into necrotic tissue or wounds, or man may become infected by handling soil, filth, or excreta. Are equipped with chewing mouth parts with which they can feed on tissues or organic material.

There exist species of flies. Them can divide into nonbloodsucking and bloodsucking kinds, and the mouth parts for every are accommodated. Because they are brought by their feeding habits in intimate contact with all kinds of flit the non-blood sucking flies in disease plays the part of mechanical transmission. We are aware that viral, protozoam, and helminthic representatives of diseases are known to be mechanically transferred by flies. Despite the act as mechanical vectors of diseases of the blood sucking flies human ailments like trypanosomiasis, leishmaniasis, onchocerciasis and loa loa these health care vectors of diseases are regarded as intermediate hosts from the transport of the disease.
