What good is it for mosquitoes to eat human blood?

The reason why mosquitoes love to bite some people may be because the substances contained in these people's bodies can improve the mosquito's fecundity when they are sucked by mosquitoes.

According to the French journal Science and Life, only female mosquitoes bite because they have to suck blood every three or four days to get the protein needed to make eggs. Therefore, in the long process of evolution, female mosquitoes have a special ability to select bites and know which people or animals have rich blood cholesterol and vitamin B.

There is an anticoagulant enzyme in mosquitoes, so the blood sucked by mosquitoes will not coagulate. Mosquitoes suck blood for reproductive needs, so mosquitoes will not die after sucking blood, except to kill it.

In fact, it is only the female mosquito that sucks blood, and it is the male that does not suck blood. The purpose of blood sucking is to replenish protein.

Female mosquitoes: generally suck the blood of humans or animals, and occasionally suck the juice of plants, once mated, they only suck the blood of humans or animals, this is because like the expectant mother, the female mosquito has a large energy demand during the egg-laying period, but can not open her mouth like a pregnant woman, so they specialize in sucking blood to meet the high demand for energy (but not all species of female mosquitoes will suck blood, like there is a pest called rice mosquito in agriculture, which is to suck the juice of rice).

Male mosquitoes: 1 sucks the sap from the inside of the plant.

Dew condensed on plants, stagnant water on the road, etc.

Suck the nectar. The physiological reason why male mosquitoes do not suck blood: the six mouth needles of male mosquitoes, because they are relatively degenerate, have short and weak jaws, so there is no way to pierce the animal's **, and naturally they can't suck blood.

After the mosquito sucks human blood, its stomach changes from bright red to milky white after sucking blood, and then it flies to a place with silver wide water to lay eggs.

Most of the mosquitoes that live outdoors are male. Male mosquitoes do not suck blood, they live by sucking nectar and grass juice, so they generally live outdoors. Most of the mosquitoes that move in the room are females. Female and male mosquitoes at first glance.

When you look closely, you will find that the tentacles on the heads of female mosquitoes are very short, and the tentacles on the heads of male mosquitoes are longer. If you cut open a pregnant mosquito with a swollen belly, you can see a milky white grain in the stomach under a magnifying glass.

colored eggs, that's the secret of its blood-sucking. It turns out that although the female mosquito also sucks nectar and grass dew, it must be sharp and shiny, and it must be bright and bright to suck blood, and the pure egg in the abdomen can mature. The female mosquito can suck the blood hard, even if the stomach is bulging, it still bites people tightly.

Don't let go. After the female mosquito has sucked the blood, she hides in a dark and damp corner where there is no wind, and lies there, without eating or moving, digesting the blood and allowing the eggs in her stomach to develop. After about two days, the blood is completely digested, the eggs have matured, and its belly has changed from bright red to milky white after the blood has been sucked, at which point it flies to a place where there is water to lay eggs.

When a female mosquito bites another healthy person, she will spit out saliva containing anti-hemomimetic agents to avoid blood clotting, but if you suck more blood and the anticoagulation does not work, then the mosquito will be miserable, and the blood will coagulate in the stomach.

edges, can not be digested.

Because female mosquitoes lay eggs by drinking blood, male mosquitoes do not drink blood, but mosquitoes that have drunk blood will definitely die, and the blood will coagulate.

Haha, ordinary mosquitoes can suck blood. But I also know a mosquito that eats and does things.

To put it simply, mosquitoes usually do not suck blood, because they do not suck blood, and they can also sustain life on other foods. However, after the mother mosquito is pregnant, she must have more nutrients to allow the embryo to grow. Therefore, at this time, mosquitoes must bite people or animals to replenish their own nutrition.

So, mosquitoes suck blood for the need to reproduce their offspring.

In order to reproduce offspring, bear mosquitoes do not suck human blood. They suck the sap of the tree.

My grandfather told me a legend. Legend has it that the ancestor of the mosquito was a large mosquito as big as a cow. It's grass-eating.

It is said that as long as you drink its blood, you can live forever. So, people worked together to arrest him. With a buzzing scream, people sliced open its belly with knives, and there was no blood in it that they longed for.

Only a swarm of small mosquitoes flew out. After that, the big mosquito died, and only a swarm of bloodthirsty little mosquitoes frantically retaliated.

Mosquitoes are also male and female, and their diet is nectar and plant juice. The mouthparts of male mosquitoes are degraded, and female mosquitoes need to bite animals to suck blood to promote the maturation of internal eggs before breeding.

Because survive! Just like people have to eat, they also need to replenish energy.

Mosquitoes are very annoying, and the most annoying thing in this world is mosquitoes.

The question is like: Why are you eating? If you figure this out, your problem is solved.

Like, mosquitoes can't eat steamed buns or something.
