1. is a person with developed sweat glands and high body temperature.
People who like sweating, the acidity in the blood is enhanced, and the discharged sweat makes the lactic acid value on the body surface higher, which is attractive to mosquitoes. In addition, mosquitoes have a heated body in their antennae, which is very sensitive to temperature. As long as the temperature difference changes a little, it can be detected immediately. People who sweat lose heat quickly and attract mosquitoes.
2. People who are tired or breathing fast.
People will breathe faster after engaging in sports or manual labor. Some people have larger lung capacity or faster breathing rhythm. In this way, the exhaled carbon dioxide is relatively large, and the carbon dioxide will form an airflow at a height of about 1 m above the head. Mosquitoes are sensitive to this and will smell it.
3. People who like to wear dark clothes.
Mosquitoes don't sleep during the day and go out at night, mainly because they have the habit of dark. If they wear dark clothes, they will have a black shadow at night, and mosquitoes will chase them to darker places. The color of clothes, such as black, is the first choice for mosquitoes to attack, followed by yellow, blue purple, blue, red and green. Mosquitoes don't like to bite white. Similarly, mosquitoes like to bite people with dark skin or red skin.
4. People with fast metabolism.
So children are easily bitten by mosquitoes, while old people are just the opposite.
5. People with makeup.
In order to verify the allure of smell to mosquitoes, American scientists tested and analyzed more than 3,900 substances with olfactory instruments. It is found that hair gel, hand cream, facial cleanser and other cosmetics are very attractive to mosquitoes. Most cosmetics contain stearic acid (a fatty acid), so people who make up are more favored by mosquitoes.
Extended data:
Mosquitoes belong to Insecta Diptera, and there are about 3000 species in the world. It is a tiny flying insect with a piercing and sucking mouthparts. Usually females suck blood, while males suck the juice of plants. Blood-sucking female mosquitoes are intermediate hosts of pathogens such as dengue fever, malaria, yellow fever, filariasis and Japanese encephalitis. Mosquitoes are distributed on all continents except Antarctica. The most famous ones are Anopheles, Aedes and Culex.
The upper lip and mandible of mosquitoes show obvious gradient, and the closer to the tip, the higher the elastic modulus and hardness. This gradient distribution of mechanical properties is helpful to improve the ability of mosquito oral needle to penetrate the skin. The numerical simulation analysis shows that the main form of instability and failure of mosquito-repellent needle is the local instability and failure of the tip, and the mechanical properties of the local material at the tip play a decisive role in the critical pressure of instability. The gradual change of mosquito's mouth needle reflects this point well and is the result of natural optimization.
