The general bio-characteristics of flies
<p>There are many species of flies. Broadly they can be divided into bloodsucking and nonbloodsucking types, and the mouth parts for each are appropriately adapted. The role of the non-blood sucking flies in disease is mechanical transmission, since their feeding habits bring them in intimate contact with all sorts of flit. Bacterial, viral, protozoam, and helminthic agents of diseases are known to be mechanically transferred by non-biting flies. Although the blood sucking flies also act as mechanical vectors of diseases, they are far more important as intermediate hosts in the transfer of such human diseases as leishmaniasis, trypanosomiasis, onchocerciasis and loa loa.</p><p><b>General Morphology</b><br>Flies have general morphology of insects. They have only one pair of wings, the second pair being rudimentary knobs called halters. For this reason, the mesothorax (middle section) is enlarged, and the prothorax and metathorax are rudimentary rings which unite the head and abdomen to the thorax. The position, venation and markings of the wings are important in species identification, Flies possess three pairs of jointed legs that end in hooked claws or in hairy pads which may secrete a sticky substance. The head possesses a pair of large, compound eyes that may or may not meet in the mid-line and a pair of sensory antennae which are jointed in different ways depending upon the species. The mouth parts of the bloodsucking flies are highly developed; skin penetration is effected through saw-like or file-like modifications of the mandible or maxilla. In the female, the terminal segment of the abdomen contains the ovipositors.</p><p><b>Maggots</b><br>Flies complete their life cycle by complex metamorphosis through four stages: Ovum, larva, pupa, and adult. Most flies procreate through the production of ova; a few species are viviparous. Although non-blood sucking flies generally spread diseases only by mechanical means, man can become infected directly by fly larva, known as maggots. Myiasis is the term used for this condition. Various tissues or organs may be involved, including the skin and wounds, the intestine, the urinary tract, nasal atria, ears and eyes. Adult flies may deposit their ova directly into wounds or necrotic tissue, or man may become infected by handling soil, filth, or excreta contaminated with fly ova. The worm-like larvae which hatch are equipped with chewing mouth parts with which they can feed on organic material or human tissues.</p><p>The adult flies most commonly concerned in myiasis belong either to the Muscidae (house fly) or the Oestridae (bot fly) families. Myasis resulting from infection of ova from muscid flies, which includes the common domestic house fly, is considered accidental in man, since the larvae usually develop in decaying organic material. In contrast, the larvae of the bot fly are obligate parasites of the intestinal tract of other tissues or mammals, including man. In this sense, they must be considered true parasites.</p><p>I am Funom Theophilus Makama. I advertise through writing.

I am sick and tired.?
Life is a fing joke. I am not going to kill myself, but do you people see how f-ed up everything is. People campaigning to make a difference in our life but they suck the knob of injustice? Propaganda? Slavery(credit or actual slavery through other debt). Sugar coated society we live in America. and I just licked the first layer.
Good question.
Hope you find the answer.
turn down the suck knob tron!
