Mosquitoes can lock on to you from 50 meters away, how do mosquitoes sense humans?

Mosquitoes can lock on to you from up to 50 meters away, and mosquitoes rely on their eye systems to sense humans.

Mosquitoes are the only very annoying animals in nature, this is because mosquitoes eat in a completely different way from other animals, although male mosquitoes can survive only by the branches and leaves of trees, but female mosquitoes need to rely on human blood to maintain their growth and development, and because of the different body structure, mosquitoes bite human beings and blood vessels, we do not have a very obvious feeling, until the mosquito flies away will feel the itch on it, At this time, we are only left with troubles, but we cannot let the mosquitoes go away from us.

Studies in medical reports have shown that mosquitoes may carry a variety of viruses, and the viruses will penetrate their own ** through mosquito bites and reach the inside of the body, resulting in a series of serious diseases. In more severe cases, it can directly lead to the death of the human body, and the virus is contagious, which means that you may have been infected with the virus before you know it. You don't need to be too nervous, because this kind of mosquito is not available in China for the time being, only in remote African areas, mosquito bites may make people sick, but you can't take it lightly, you still need to carry out active mosquito repellent methods to keep mosquitoes away from you.

Mosquitoes have a very developed line of sight, and can see the blood that attracts them from a long distance, and perceive which part of the human body has more blood content according to the bristles on their body. When the location is determined, the mosquito will pierce its mouthparts directly into the body** and will release an enzyme that makes the body feel no pain. So that's why a lot of people who are easy to attract mosquitoes will have a lot of bags on them, and no matter how much mosquito repellent they use, they will not be indifferent.

Mosquitoes like to bite on blood type O.

There is also a case of carbon dioxide.

Where the concentration is too high, it is also a gathering place for mosquitoes.

Carbon dioxide emitted by humans. People who emit more carbon dioxide have a strong feeding habit for mosquitoes, and the antennae of mosquitoes can sense the information of the human body in the air.

Mosquitoes rely on the carbon dioxide produced when we humans breathe to determine our location.

One pair of tentacles and three pairs of feet of mosquitoes. These areas are dotted with a number of whorls of sensory hairs, each densely arranged with round or oval pores. In the dark, mosquitoes use this sensor to sense the carbon dioxide emitted by people in the air, and quickly respond to the circular rubber of living things.

Mosquitoes are small flying insects with stinging and sucking mouthparts. Multicellular organisms with slender bodies and feet, usually females feed on blood, while males feed on plant sap and prefer to inhabit hidden, dark and poorly ventilated places, and are found on all continents except Antarctica.

On one pair of tentacles and three pairs of feet, there are many whorls of sensory hairs, each of which is densely arranged with round or oval pores. In the dark, mosquitoes can use this sensor to sense the carbon dioxide emitted by the human body in the air, and respond within one hundredth of a second, so that they can fly to the blood-sucking object with agility. <

On one pair of tentacles and three pairs of feet, there are many whorls of sensory hairs, and each sensory hair is densely arranged with round or oval pores. In the dark, mosquitoes can sense the carbon dioxide emitted by the human body in the air with this sensor, and respond within 1 percent of a second, so that they can fly to the blood-sucking target correctly and agilely.

You can light mosquito coils, put toilet water, bring mosquito repellent bracelets, spray insecticides, and hang mosquito nets.

We have to learn to avoid mosquitoes, mosquitoes have a soft spot for people who sweat a lot and have a fast metabolism, so we should try to keep the body dry, mosquitoes have darkening, so we should choose some bright-colored clothes to reduce the chance of being stared.

Mosquitoes do not rely on their eyesight to find their blood-sucking targets, because mosquitoes can still suck blood in the dark. They rely on smelling carbon dioxide exhaled by people and animals, which is much more effective than seeing a blood-sucking object. However, if you rely only on carbon dioxide, mosquitoes should fly all the way to the mouth of the person, or concentrate near the mouth and nose, why do they turn to ** after getting close to the human body?

An article published in Cell a while ago gave an explanation.

Carbon dioxide receptors on mosquitoes' jaw whiskers = are also very sensitive to the smell of **, which explains that even in the absence of carbon dioxide, mosquitoes like smelly socks, torn clothes, bed sheets, etc.

Mosquitoes live by sucking the blood of other animals, and this creature appeared 40 million to 60 million years ago, when humans did not even have a hair, and mosquitoes sucked the blood of various animals. After tens of millions of long years, humans finally appeared, and the mosquitoes that were very adaptable sucked the blood of animals as well as human blood. Since then, the number of human beings has increased, and it has spread to all corners of the earth, and human blood has become one of the staple foods of mosquitoes.

1.The CO2 you exhale, changes the CO2 concentration of the environment, and it takes off.

2.Find the approximate location (your room or something) based on the CO2 concentration, just feel your body temperature (one says infrared), and then find you.
