Lifetime mosquito goes through the following stages: egg, larva, pupa, imago.It is known that only the females bite and drink human blood.This comes just after mating.The blood is digested and simultaneously the process of egg maturation.When the time comes, the female begins to lay eggs.The venue for this could be even a small puddle, a groove or a pit filled with water.Mosquitoes find a place, focusing on the humidity.Egg laying occurs in the following ways:
1. Each egg separately, one by one.
2. "Party" - the eggs are glued together.
For once, the female lays about one hundred and twenty - one hundred and fifty eggs.Lifespan mosquitoes at this stage depends on water temperature.Also plays a significant role and safety of the selected location.In general, the average of eggs ranges from forty hours to eight days.Upon completion of this stage, the larvae appear quite moving, the body which consists of the head, chest, abdomen, and the size of about two millimeters.Supply for the larvae are organisms that live in the water, plants and so on.To the naked eye to detect larvae very easily.They usually hang out on the water surface.
Over the lifespan of the mosquito (in the larval stage), he molts four times, and after the last molt turns into a pupa.The body resembles a comma and consists of a massive cephalothorax and abdomen tapered hem.Pupa long enough may be under water in motion, and more protected from external influences.By the end of this stage, it changes color to almost black.
Lifetime mosquito at this stage is governed by a very complex process, which occurs as a result of an adult, ready to fly, the mosquito imago.The protective cover on the back of the pupa breaks, and through the crack head is released first, followed by the chest and in the end - the limbs and wings.A few minutes after the "birth" of a mosquito arrives on the greens, growing near a pond.Males always appear before the females.They gather in a place in the breeding swarms, as if waiting for their future, "brides" to continue the cycle of the birth of new species.Bloodsucking instinct wakes up in fertile females.When she is hungry, you can smell the scent of humans and animals at a distance of three kilometers.For one mosquito bite can suck the blood more than its own weight.Life expectancy-female mosquito is two to three weeks, and sometimes - and about 120 days (under favorable conditions).Males live much less.
During the warm season has time to grow three or four generations of mosquitoes, and in the southern latitudes - twice.
Recently, scientists have come to the conclusion that the poor conditions of the environment and the deterioration of the environment is not affected by how, and how many live mosquitoes on their ability to reproduce.On the contrary, these insects are perfectly adapted and changed its key signs of life.For example, a mosquito may well live and breed in dirty water.
