1. The purpose of biting
The mosquitoes that bite people are all female mosquitoes, and the male mosquitoes only drink dew, and the purpose of female mosquitoes biting people is because mosquitoes cannot produce certain proteins for reproduction on their own, and these proteins can be obtained from the blood pressure of mammals, so mosquitoes will come to bite people, and of course they will bite other mammals. After the mosquito sucks up the blood, it will find a place to break down the blood and use the swimming protein to produce egg cells, this process takes about 3-4 days, and then the mosquito may go to lay eggs, or continue to suck blood until the demand is satisfied.
2. Envy of finding a way to find someone
Mosquitoes can also delicately find people in the dark and suck blood, how does this work? The reason is that the eyes of mosquitoes are different from our humans, the eyes of mosquitoes are compound eyes, accounting for 3 4 of the head, they can see a wide range of things, and at night, mosquitoes can also see the infrared radiation of the human body, and mosquitoes are delicate in this way to find the position of the lower mouth. Mosquitoes do not look for targets through their eyes at first, and the olfactory organ of words is also very powerful, which can smell the smell of body fluids emitted by prey, so that mosquitoes can find the general direction of their prey, and the smell of sweat emitted by the human body can attract mosquitoes within a range of tens of meters.
3. Blood sucking method
The process of mosquito bites is also not simple, it is not directly poked into the mouth like a needle, the process is very complicated. In order to avoid being detected, mosquitoes will inject a small amount of anesthetic into the ** before the mouth, and then in order to facilitate the puncture**, they will inject formic acid into the **, and wait until the straw enters the blood vessels, in order to prevent blood clotting, the anticoagulant component will be injected into the blood, and then the mosquito can start sucking blood. Among them, formic acid can cause itching in the human body, while anticoagulants can cause allergic reactions, that is, redness and swelling.
