about the most dangerous fly every schoolboy knows.CC Fly lives on the African continent.And now, 150 years is frightening the local population and animals.In some areas, people throw the fertile plantations and go to other places.In these lands is not terrible bloodsucker, fly than CC.What is she guilty, if in fact it does not emit its own venom?The main reason for the deaths of thousands of people - the dangerous parasite trypanosome that carry this insect.
How does a fly IC
Normal view, almost like a very ordinary flies, still has its distinctive features.On his head there is a long proboscis, which allows females to bite through the skin of people and animals and feed on blood.Translucent wings that fold up flat state when the fly alone.At the bottom of the insect gray abdomen, and on top - yellow, red on the chest are four longitudinal dark stripes.The adult fly IC, which is represented by the above photo, for his life lays up to 10 larvae, which, falling on the ground, burrow and pupate within a few hours.
How infection occurs
process of infection is inevitable if a fly IC at least once fed on the blood of carriers trypanosomiasis (or "sleeping sickness").According to scientists, to blame wild antelopes and other mammals that live in the blood of this parasite.And the animals themselves from this disease do not die.Sleeping sickness is not immediately.First, the patient feels weakness, fatigue, changes occur in the central nervous system.Man exhausted, often loses consciousness and falls into a deep sleep semiconscious, his body appearing seals, is the development of meningoencephalitis, resulting in death.And not only killed indigenous people.Dozens of tourists after returning from Africa is infected with sleeping sickness.
for cattle fly IC is no less dangerous.It causes the death of animal disease - a revolver, which also transferred to these bloodthirsty insects.On the sad statistics, from the bites of tsetse flies die each year 3 million head of cattle.
scientists looking for a way
inhabitants of Africa and Australia, is home to this bloodsucker, waiting for deliverance from danger.But to date there is no cure for the "sleeping sickness" or ways to destroy tsetse fly.Trypanosomes are very aggressive in the human body, they mutate and mutate, so it is impossible to kill all the mutations one drug.Destroyed several parasites, and the rest will continue their livelihoods.
scientists lay great hopes on a new way to reduce the population of the tsetse fly.Fly mates with a male only once in life.Knowing such a feature, the researchers decided to release into the wild, millions of sterilized males.To this end specially grown and their radiation is irradiated.The female, once paired, will not admit to himself another male, but also produce offspring would not be able.This method, according to experts, will eliminate the carriers of deadly diseases.And about a few years fly IC disappear from the face of the planet.
