Flies do not live longer than 15 days in summer and 25 days in winter. House flies are carriers of numerous pathogenic bacteria.
House fly produces sticky substance which keeps the fly firmly attached to the ground it acts like glue after landing. Long exposure to freezing weather kills flies.
Some five days later an adult fly emerges from the pupa case.
In 16th- and 17th-century European vanitas paintings, flies sometimes occur as memento mori. Unhygienic rubbish tips are a prime fly-breeding site, but if garbage is covered by a layer of soil, preferably daily, this can be avoided. Search Introduction While some flies are beneficial to humans as parasites of insect pests or as scavengers and many others are important as plant pollinators, flies are also known to be carriers of such serious diseases as cholera, typhoid, and dysentery.
Some of these rank also among the deadly disease carriers see mosquito.
House flies undergo complete metamorphosis: More useful members of the order are the syrphus flies, which resemble bumblebees and wasps and destroy plant lice; drone flies, whose larvae live in foul water, eating decaying vegetable matter; and robber flies, which consume other insects. The pupal case is cylindrical with rounded ends, about 1.
Blow Flies — They have metallic blue green color bodies with size ranging from 6 mm — 14 mm.
The housefly is, however, thought to exhibit multiple mechanisms for sex determination, such as male heterogamy like most insects and mammalsfemale heterogamy like birdsand maternal control over offspring sex. The larva feed on decaying organic matters.
Human flies are pests because they easily reproduce and transmit numerous diseases. The adult housefly lives from two weeks to a month in the wild, or longer in benign laboratory conditions.
The larva is 12 segmented, white in color and about mm in length at birth. A "swat that fly" contest was held for children in Montreal in The Shandong attack killed ,; the occupying Japanese troops had been vaccinated in advance.
Unlike other insects, house fly has only one pair of membranous wings. The excrement of housefly has been found to contains microorganism, cyst and ova of intestinal parasites.
This could be exploited to combat ever-increasing amounts of waste. During cold weather the larvae-pupae stage may last for weeks or even months, with the adult fly emerging in warm weather. The complete life cycle from egg to adult may take days during summer.
It relies more upon its acute sense of smell to locate its food. Infected flies have been known to seek high temperatures that could suppress the growth of the fungus. Sticky fly papers hanging from the ceiling can also be effective.
In temperate regions, 12 generations may occur per year, and in the tropics and subtropics, more than The pupa stage lasts from days but in winter it may be prolonged. Oxidative DNA damage 8-hydroxydeoxyguanosine in houseflies was found in one study to increase with age and reduce life expectancy supporting the hypothesis that oxidative molecular damage is a causal factor in senescence aging.
This cuticular hydrocarbon is not released into the air and males sense it only on contact with females;  it has found use as in pest control, for luring males to fly traps. In place of the second pair of wings possessed by bees, dragonflies, and many other insects, true flies have club-shaped balancers halteres.
Flies do not live longer than 15 days in summer and 25 days in winter.House fly spits digestive juices on the food to decompose it before swallowing. House flies are carriers of numerous pathogenic bacteria. Gangrene, tuberculosis, dysentery, anthrax, plague and different types of poisoning are just some of diseases transmitted by flies.
The housefly's thorax features all of its limbs used for movement. Though flies appear to have only one pair of wings, closer inspection reveals the presence of tiny, secondary wings, called halters, located below the main pair.
House fly puparia, each with a hole from which a single wasp emerged after feeding on the pupa. Feeding occurs in the larval stage, and the wasp eventually emerges as an adult. Photograph by USDA. The housefly's thorax features all of its limbs used for movement.
Though flies appear to have only one pair of wings, closer inspection reveals the presence of tiny, secondary wings, called halters, located below the main pair. The order Diptera is divided into two suborders (although one suborder is non-monophyletic), with about families divided between them; the families contain an estimated one million named species, including the familiar housefly, horse-fly, crane fly, and hoverfly; although only aboutspecies have a species description published.
House fly is a potential vector of many diseases like typhoid, paratyphoid fever, diarrhea, dysenteries, cholera, gastroenteritis and amoebiasis. Habits of House fly. The habits of housefly make it suitable for the spread of disease. Distribution: The housefly occurs all over the world.Download
