Fly tzc - the carrier of a deadly disease

Every schoolboy knows the most dangerous fly. The fly tzc lives on the African continent. And for 150 years, the local population and animals have been frightened. In some areas, people abandon fertile plantations and go elsewhere. In these lands there is no more terrible bloodsucker than a fly tz. What is she so guilty of, if in fact does not allocate its own poison? The main reason for killing thousands of people is the dangerous parasites of trypanosome, which is carried by this insect.

How does the fly look like?

The usual appearance, almost like the most ordinary fly, still has its own distinctive features. On the head there is a long proboscis that allows females to bite the skin of people and animals and feed on blood. Wings are translucent, which fold up to a flat state when the fly is at rest. The insect has a gray abdomen from below and yellow on top, four longitudinal dark strips on the red chest. The adult fly tsh, the photo of which is presented above, during its life lays up to 10 larvae, which, falling to the ground, burrow and pupate for a few hours.

How does the infection occur?

The process of infection is unavoidable if the fly has at least once fed on the blood of carriers of trypanosomiasis (or "sleeping sickness"). According to scientists, wild antelopes and other mammals, in whose blood this parasite lives, are to blame for everything. And the animals themselves do not die from this disease. Sleepy illness does not appear immediately. At first the patient feels weakness, fatigue, changes in the central nervous system. A person is exhausted, often loses consciousness or falls into a deep fainting dream, his body becomes densified, development of meningoencephalitis occurs, as a result, death occurs. And not only the indigenous people die. Dozens of tourists after returning from Africa were infected with sleeping sickness.

For cattle, the fly tzc is no less dangerous. Death leads to animal disease - Nagana, which is also carried by these bloodthirsty insects. According to the sad statistics, 3 million cattle die every year from the tsetse fly bites.

Scientists are looking for an exit

The inhabitants of Africa and Australia, where this bloodsucker lives, are waiting for escape from danger. But to date, there is no cure for "sleeping sickness" or ways to destroy the tsetse fly. Trypanosomes behave very aggressively in the human body, they mutate and mutate, so it is impossible to kill all mutations with one medicine. Several parasites will be destroyed, and the rest will continue their vital activity.

Scientists pin great hopes on a new way of reducing the tsetse fly population . The fly mates with the male only once in a lifetime. Knowing this feature, scientists decided to release millions of sterilized males into nature. To do this, they are specially grown and irradiated with radiation. The female, once mated, will not allow another male to come to her, but she will not be able to produce her offspring. This method, according to experts, will relieve the carriers of the deadly disease. And after a few years the fly will disappear from the face of the planet.
