Open strange subspecies mosquito

Still Life with mosquitoes (photo quapan).

Parasitologists from the Institut Pasteur (France) discovered an unusual subspecies of mosquito.

In sub-Saharan Africa dies of malaria about 710 thousand people a year. The most dangerous form of the disease caused by a parasite called Plasmodium tropical (Plasmodium falciparum), carried mainly by mosquitoes of the complex of cryptic species of Anopheles gambiae. Mosquito larvae live in water, and adult insects are believed to spend b? Most of the time in buildings where relish human blood.

Sprays, nets and drugs have helped reduce malaria deaths in the last decade. But victory over the disease is still very far away.

Subspecies of A. gambiae, Goundry named after the village in Burkina Faso, where it was found, is probably one of the reasons why all attempts to eliminate malaria were not very successful. Unlike relatives, gaundri prefers to live "on the street" where he was not afraid of any sprays. In addition, the study showed that it is "more likely" other mosquito becomes a carrier of the parasite.

Head of the research group Ken Vernick suspects subspecies eluded scientists because of wrong approach to the collection of material. The majority of cases infected through bites received at home, so scientists and fixated on mosquitoes living in the buildings.

There is another reason: the hunt for mosquitoes in the open is extremely difficult. Artificial bait is ineffective, and people use for this purpose is prohibited. It is easier to collect the larvae than French researchers and engaged.

Specimens grown in the laboratory to adulthood, after exhaustive genetic analysis. 58% gaundri were carriers of the parasite.

Suspicions about the "external" mosquito first emerged in the 1970s, after the failure of the WHO malaria cost $ 6 million in the Nigerian region Garqi. Extensively used the most effective sprays and medicines, and to no avail.

The study is published in the journal Science.
