I would like to say a few words about mosquitoes. They are very nasty insects. They parasites on all living beings: people, animals. In Russia, mosquitoes are relatively harmless, although there is a huge number of them in Russia. But, in southern countries, in the tropics, mosquitoes are very dangerous. Their bite can kill a person. Theу are malarial mosquitoes...  The disease that they carry is called malaria. The mosquitoes breed on a warm time..
