Mosquitoes do have this "tendency to eat", it is not that people imagine that some people's skin is delicate, sweet blood to attract mosquitoes, the main reason is because of some of the breath on their bodies to attract mosquitoes. Generally speaking, the following kinds of people mosquitoes will be "fond of":

1. is a developed sweat glands, higher body temperature.

People like to sweat, blood acidity enhancement, the sweat makes the body surface lactic acid value is high, the mosquito attraction. In addition, the mosquito tentacles have a heat receptor, it is very sensitive to temperature, as long as there is a little temperature change, it can be immediately detected, sweating people muscle heat dissipation fast, but also on the mosquito attraction.

2. It is the people who are tired or have a faster breathing rate.

People engaged in sports or physical labor after breathing will be accelerated, some people have a larger lung capacity, or the breathing rhythm itself is faster. This exhaled relatively more carbon dioxide, carbon dioxide will be in the head about 1 meter or so to form a stream of air, mosquitoes are more sensitive to this, will smell.

3. Is like to wear dark-colored clothes.

The reason why mosquitoes day and night, mainly because it has the habit of darkness, if you wear dark clothes, at night will show a dark shadow, mosquitoes will be to the darker place to chase and go. Clothing colors such as black is the preferred object of the mosquito attack, followed by yellow, blue and purple, blue, red, green, etc., mosquitoes do not love to bite white. Similarly, mosquitoes love to bite people with darker skin color or reddish skin color.

4. is a fast metabolism.

Therefore, children are susceptible to mosquito bites, while the elderly are the opposite.

5. People who wear makeup.

In order to verify the lure of the smell of mosquitoes, American scientists used olfactory instruments to test and analyze more than 3900 kinds of substances. The results found that many types of hairspray, hand cream, face wash and other cosmetics are unusually seductive to mosquitoes. Most cosmetics contain stearic acid (a type of fatty acid), so people who wear makeup are more "favored" by mosquitoes.

Expanded:

The mosquito (mosquito), belonging to the insect order Diptera, family Mosquitidae, has about 3,000 species worldwide. It is a small, slender flying insect with a piercing-sucking mouthparts. Usually the female takes blood as food, while the male sucks the sap of plants. Blood-sucking female mosquitoes are intermediate hosts for other pathogens such as dengue fever, malaria, yellow fever, filariasis, and Japanese encephalitis. Mosquitoes are found on all continents except Antarctica. Among them, the genera Anopheles, Aedes and Culex are the most famous.

Mosquitoes show a clear gradient in both the upper lip and the lower jaw, and the closer to the tip, the higher the values of modulus of elasticity and hardness, and this gradient distribution of mechanical properties contributes to the ability of mosquito mouth needles to penetrate the skin. Numerical simulation analysis found that the mosquito mouth needle destabilization damage occurs mainly in the form of tip local destabilization damage, and the mechanical properties of the tip local material play a decisive role in the size of the critical pressure of destabilization. The gradient property exhibited by the mosquito mouth needle reflects this well and is a natural optimization result.
