It is not for nothing that mosquitoes are considered the most dangerous creatures on our planet: they spread diseases and parasites that kill at least two million people around the world every year. So why haven't we gotten rid of them yet?
Science knows more than three thousand species of mosquitoes belonging to 38 genera. Most of them, however, do not feed on human blood, but on nectar. Exclusively females 6% of all mosquito species drink human blood and only half of them carry parasites.
However, the impact of these few species on humans is truly devastating. Mosquitoes can act as carriers of diseases that are dangerous to human health and life - pathogenic bacteria, viruses and parasites. Infected mosquitoes can safely transfer viruses and parasites from person to person. They are involved in the transmission of various types of diseases in more than 700 million people a year, mainly in Africa, South America, Central America, Mexico, Russia and most of Asia, with millions of deaths - at least two million people die annually from these diseases. and the incidence rate is many times higher than the officially registered one.
So isn't it easier to take and destroy all mosquito species that carry deadly diseases? It turns out not.
The fact is that the destruction of mosquitoes in nature will cause a huge negative effect. Mosquitoes feeding on flower nectar play an important role in pollination; they feed birds and bats, and fish and frogs feed on their larvae. The problem also lies in the fact that the niche occupied by mosquitoes will inevitably be occupied by other insects that are no less dangerous to human health. Moreover, it is mosquitoes that make tropical rain forests unsuitable for human life, which protects them from destruction.
Be that as it may, the complete destruction of mosquitoes is an almost impossible task, and most importantly, pointless.
