Mosquitoes

They come from vegetable storage, cellars, hollows and other winter shelters when the air temperature after sunset is significantly above zero. Females are blood-sucking mosquito, while the males feed on flower nectar. Most often, mosquitoes fly into barns, piggeries and stables. Here in the dark, sit dormant in the animal to drink his warm blood. Attacked by malarial mosquitoes and humans. If a mosquito suck blood of a malarial patient, he himself becomes infected with a parasite - the agent of malaria. But an infected mosquito do not immediately dangerous. Held quite a few days until the microscopic parasites from the stomach to penetrate into the bloodstream, and thence to the mosquito salivary glands. Only after this bite of the female mosquito can cause illness of another person. In summer, hot weather, mosquitoes can "instill" human malaria two weeks after he drank the blood of malaria patients, while the cool spring temperatures - not less than two decades and more. In any case, the bite of female mosquito shortly after departure from wintering more secure. Even those mosquitoes that were infected in the autumn to spring are secure, as the parasites they die in the winter. Meanwhile, in the spring and especially in May seen the greatest number of complaints of patients, malyarikov medical help. How can we explain this contradiction? Very simple. In the spring manifested disease, which before was in latent form, and therefore, the contamination occurred many months before - last fall or summer. In such a latent form, malaria can be quite a long time to strengthen the activities of the parasites that very often it happens in May. But here komariha suck blood. What next? Red blood in her stomach on the day was getting dark. Then bloated stomach starts to gradually decrease. The blood is digested, and at the same time, the rudiments of the testes in female reproductive organs are growing. They grow at the expense of those nutrients that were digested blood. Abdomen komarihi 4-5 days whitens already evolved from the testes. In the middle zone of our Union at the end of April komarihi begin to lay eggs. In cold spring clutch pushed into early May. From daytime shelters females emerge at night and are attracted to water. How did they find her? Mosquitoes are buried, distinguish dry and wet air. They fly to where the feeling damp. If the water is calm, the female sits na edge of a floating object or directly to water. Komarpha so easy that a free float?. Surface film of water only bend under it. Hairs and scales its legs are not wetted. First of all, the female begins to drink. And as it fills the stomach, lungs long balls slip out of the rear end of her abdomen. In small, rapidly heated pools of the first larvae are already in early May. In the south it happens, of course, much earlier. Newly hatched larvae are very small - about the number of millimeters in length. Distinguish the larva of the mosquito larvae Kusaka (aedes) or the distribution of bird malaria - a mosquito-Piskun (kuleks) - can be read. The first stick horizontally at the surface of water, the second and third - his head down. Do not think that the aedes mosquitoes are nothing dangerous. In the subtropical species of this genus is a carrier of the terrible yellow fever. Recently, these mosquitoes were suspected of spreading the dangerous disease meningitopodobpogo horses. Along with mosquito larvae in puddles warmed poked all sorts of other aquatic insects: predatory predaceous diving beetles, water bugs, crawling along the bottom of caddisfly larvae and dragonflies.
