Why do mosquitoes feed on insects? What kind of people do you like to bite? Which plants can repel mosquitoes?

Mosquitoes belong to the family Diptera, Insecta. There are about 3000 species in the world. It is a small flying insect with piercing and sucking mouthparts. Usually females feed on blood, while males feed on plant juices. So do you know why mosquitoes suck blood? What kind of people do you like to bite? Which plants can repel mosquitoes?

Why do mosquitoes suck blood?

Because after mating, if the female mosquito does not suck blood, the egg cannot mature. After mating, the female mosquito flies to the surface to lay eggs every time she sucks blood. After several times of laying eggs, the female mosquito will die. Some female mosquitoes can survive the winter indoors. Most male mosquitoes also die soon after mating with females.

What kind of people do mosquitoes like to bite

1. Mosquitoes like people with well-developed sweat glands and high body temperature.

People who like to sweat have increased acidity in the blood, and the sweat excreted makes the body surface lactic acid higher, which is attractive to mosquitoes. In addition, there is a heating body in the mosquito's antennae, which is very sensitive to temperature. As long as there is a slight temperature difference, you can immediately detect that the sweating human body dissipates heat quickly and will also attract mosquitoes.

2. Mosquitoes like people who are tired or breathe faster.

Mosquitoes find their prey by smell. Carbon dioxide has a strong attraction to mosquitoes. Mosquitoes have carbon dioxide receptors on their small tentacles, which can sense substances such as carbon dioxide and lactic acid. The carbon dioxide emitted by a person's breath can be detected by mosquitoes at a distance of 15 meters.

After engaging in sports or manual labor, people's breathing will speed up, at this time the exhaled carbon dioxide is relatively large, and the carbon dioxide gas will form a moist and warm airstream about 1 meter above the head, to which mosquitoes are more sensitive. Will smell and come. By the same token, people with large vital capacity or faster breathing rhythm exhale more carbon dioxide, and mosquitoes come in groups when they smell it.

Mosquitoes like people who wear dark clothes.

Because black is the preferred target for mosquitoes, such as Aedes albopictus (also known as flower mosquitoes), they prefer to park on black clothes. Followed by blue, red, green and so on, mosquitoes do not like people who wear white clothes. In the same way, mosquitoes like to bite people with darker skin or reddish skin.

4. Mosquitoes like people with fast metabolism

Generally speaking, men attract mosquitoes more than women, young people than old people, and healthy people than sick people, because there are more secretions on the surface of the skin. Women in the period, secretions change, but also more attractive mosquitoes. Mosquitoes have "food tropism". This is not because people think that some people have delicate skin and sweet blood to attract mosquitoes. The main reason is that some smells on their bodies attract mosquitoes.

5. Mosquitoes like pregnant women

Pregnant women are particularly easy to attract mosquitoes. Pregnant women are particularly attracted to mosquitoes, and they are twice as likely to be bitten by mosquitoes as other women, according to a US medical study.
