	~~The~~ ''~~'tsetse fly''' is a large biting fly belonging to the genus ''[[~~Glossina]]'' ~~in the family [[Glossinidae~~]]~~. These flies are found in tropical Africa and are known for their role in transmitting the parasites that cause [[African trypanosomiasis]], or sleeping sickness, in humans and [[nagana]] in animals.~~		[[File:Glossina-morsitans.jpg\|''Glossina morsitans''\|thumb\|right]]

	~~== Description ==~~		Tsetse flies are large biting flies that inhabit much of tropical Africa. They belong to the genus ''[[Glossina]]'' in the family [[Glossinidae]]. Tsetse flies are known for their role as vectors of the [[trypanosomiasis]] parasites, which cause [[sleeping sickness]] in humans and [[nagana]] in animals.

	Tsetse flies are robust ~~flies~~ with a ~~length of 6 to 14 mm~~. They have a ~~characteristic~~ proboscis, which is ~~a long, forward-projecting structure~~ used for ~~feeding on~~ the ~~blood~~ of ~~vertebrate~~ hosts. The ~~wings~~ of tsetse flies ~~are held in~~ a ~~scissor-like position~~ over the ~~abdomen when at rest~~. The ~~flies are distinguished by~~ a hatchet~~-shaped~~ cell in the wing, ~~known~~ as the ~~"hatchet cell"~~.		== Morphology ==

			Tsetse flies are robust insects with a characteristic morphology that distinguishes them from other flies. They have a long proboscis, which is used for piercing the skin of their hosts to feed on blood.

			[[File:tsetse_head-proboscis.jpeg\|Tsetse fly head and proboscis\|thumb\|left]]

			The head of the tsetse fly is equipped with large, forward-facing eyes and a pair of antennae. The proboscis is a prominent feature, adapted for blood-feeding.

			[[File:tsetse_foldedWings.jpeg\|Tsetse fly with folded wings\|thumb\|right]]

			Tsetse flies have a unique wing structure. When at rest, their wings fold completely one over the other, which is a distinctive feature of the genus ''Glossina''.

			[[File:tsetse_hatchetCell.jpeg\|Hatchet cell in tsetse fly wing\|thumb\|left]]

			The wings also have a characteristic "hatchet cell," a cell in the wing that is shaped like a hatchet, which is used as a key identification feature.

			[[File:tsetse_aristaHairs_labeled.jpeg\|Arista hairs on tsetse fly\|thumb\|right]]

			The antennae of tsetse flies have a distinctive structure with arista hairs, which are sensory organs that help the fly detect its environment.

	== Life Cycle ==		== Life Cycle ==

	Tsetse flies ~~undergo~~ a unique reproductive ~~process among~~ insects~~. Female~~ tsetse flies give birth to live ~~larvae~~, which ~~are deposited in the soil. The larvae quickly burrow~~ and ~~pupate, emerging as adult flies after several weeks. This viviparous reproduction~~ is ~~supported~~ by specialized milk glands ~~in the female fly~~.		Tsetse flies have a unique reproductive biology. Unlike most insects, tsetse flies give birth to live young. The female tsetse fly produces a single larva at a time, which develops internally and is nourished by specialized milk glands.

	~~== Habitat and Distribution ==~~		[[File:G ndulas_de_la_leche_de_Glossina_.gif\|Milk glands of ''Glossina''\|thumb\|left]]

	~~Tsetse flies inhabit a variety of environments across sub-Saharan Africa, including savannas, woodlands~~, ~~and riverine areas. Their distribution~~ is ~~closely linked to~~ the ~~presence of suitable hosts~~ and ~~environmental conditions that support their life cycle~~.		The milk glands provide nutrients to the developing larva, which is then deposited in the soil where it pupates and eventually emerges as an adult fly.

	== ~~Disease Transmission~~ ==		== Medical Importance ==

	Tsetse flies are ~~vectors for~~ the ~~[[Trypanosoma]] parasites, which cause~~ sleeping sickness in humans and nagana in animals. ~~The disease is transmitted when an infected fly bites~~ a ~~host, injecting the parasites into the bloodstream. Control of tsetse populations is crucial~~ in ~~managing the spread of these diseases~~.		Tsetse flies are of significant medical importance due to their role in transmitting trypanosomes, the causative agents of sleeping sickness in humans and nagana in animals. These diseases have a profound impact on human health and agriculture in affected regions.

	== Control Measures ==		== Control Measures ==

	Efforts to control tsetse fly populations include the use of insecticide-treated traps ~~and targets~~, sterile insect ~~technique~~, and habitat modification~~. These methods aim to reduce the population of flies and interrupt the transmission cycle of the trypanosome parasites~~.		Efforts to control tsetse fly populations and reduce the incidence of trypanosomiasis include the use of insecticide-treated targets and traps, sterile insect techniques, and habitat modification.

'''Tsetse fly''' (''Glossina'') is a large, brown, biting fly that serves as both a host and vector for the trypanosome parasites. It is native to Africa and is the primary vector of [[African trypanosomiasis]], also known as sleeping sickness in humans and nagana in animals.

== Biology ==
Tsetse flies include 23 species that are all native to Africa. They are obligate parasites that live by feeding on the blood of vertebrate animals. Tsetse flies are distinguished from other Diptera by unique adaptations, including a forward-projecting proboscis, and the fusion of the male and female genitalia during mating.

== Life cycle ==
The life cycle of the tsetse fly consists of the following stages: egg, three larval stages, a pupal stage, and the adult stage. The entire life cycle is completed in 20 to 30 days.

== Disease transmission ==
Tsetse flies are vectors for the trypanosomes that cause [[Human African trypanosomiasis]] and [[Animal trypanosomiasis]]. The flies receive the trypanosome parasites by biting an infected human or animal, and can then transmit the disease when they bite another host.

== Control ==
Control of tsetse flies and the diseases they carry is a major public health issue in Africa. Methods include trapping, pesticide application, and sterile insect technique.
