Scientific Name : Musca domestica
Family : Muscidae
Tamil Name : Ee
Description : The whole body is covered with hair-like projections. The females are slightly larger than the males, and have a much larger space between their red compound eyes. Like other Dipteran (meaning “two-winged”), houseflies have only one pair of wings; the hind pair is reduced to small halters that aid in flight stability.
Distribution and status: This common fly originated on the steppes of central Asia, but now occurs on all inhabited continents, in all climates from tropical to temperate, and in a variety of environments ranging from rural to urban. It is commonly associated with animal feces, but has adapted well to feeding on garbage, so it is abundant almost anywhere people live.
Life cycle: Each female fly can lay approximately 9,000 eggs in a lifetime, in several batches of about 75 to 150. The eggs are white and are about 1.2 mm in length. Within a day, larvae hatch from the eggs; they live and feed on (usually dead and decaying) organic material, such as garbage, carrion or feces. They are pale-whitish, 3–9 mm long, thinner at the mouth end, and have no legs. Some 36 hours after having emerged from the pupa, the female is receptive for mating.
Role in the environment: In colder climates, houseflies survive only with humans. They have a tendency to aggregate and are difficult to dispose of. They are capable of carrying over 100 pathogens, such as those causing typhoid, cholera, salmonellosis, bacillary dysentery, tuberculosis, anthrax, ophthalmia, and parasitic worms. Some strains have become immune to most common insecticides. The more commonly used control measures for house flies are sanitation, use of traps, and insecticides, but in some instances integrated fly control has been implemented. The use of biological control in fly management is still at a relatively early stage.
