Do mosquitoes have eyes? Why drink human blood? Not eating food?

Yes, male mosquitoes are vegetarian.

Mosquito profile:

Mosquitoes belong to the order Diptera, family Culicidae, and are insects with complete metamorphosis. There are 350 known species of mosquitoes in my country, but there are more than 10 species that are important in transmitting diseases and disturbing people by sucking blood. Anopheles, Culex, and Aedes can respectively transmit infectious diseases such as malaria, dengue fever, filariasis, and Japanese encephalitis. Mosquitoes grow and develop in four stages: egg, larva, pupa, and adult. Mosquitoes live in water, and adults live on land.

The main harmful species of mosquitoes:

Culex quinquefasciatus is commonly known as Aedes mosquitoes. Medium size, black body with white spots in between, a white vertical stripe in the middle of the midback, white rings on the hind metatarsal joints, and all white distal segments. Adult mosquitoes mostly suck the blood of humans and animals during the day, and they mostly inhabit bamboo forests, woods, or grass in front of and behind houses. They are also commonly found in construction sheds, and sometimes rest in dark corners indoors.

Culex mosquitoes are commonly known as house mosquitoes. Medium size, light brown, back and legs dark brown, there is a gray horizontal band at the base of the back of the abdominal segment, which protrudes in an arc backward, forming a half-moon shape. Adult mosquitoes are addicted to sucking human blood, as well as the blood of poultry and livestock. They inhabit human houses and livestock houses, as well as in grass and shrubs near their habitats.

The Aedes albopictus mosquito is larger and gray-black or dark black in color. The female mosquito has 4 white rings on its tentacles, 2 white spots on the front edge veins of the wings, and a narrow terminal white ring on the running joints of the hind legs. Adult mosquitoes live semi-wild. During the day, they mostly live in outdoor shrubbery or in cattle pens and livestock houses. They enter human and livestock houses after dusk and like to suck the blood of cattle and pigs, as well as human blood.

Mosquitoes that harm humans:

Although mosquitoes are small, people are afraid of them and hate them. What is this?

First of all, let’s talk about the origin of mosquitoes: Female mosquito eggs are laid in water, and after a day or two they hatch into larvae, called larvae. The larvae molt four times and turn into pupae. The pupae continue to live in the water for two days before emerging into adult mosquitoes. It only takes about 10 to 12 days to complete the development of one generation, and can reproduce seven or eight generations a year. Mosquitoes rely on blood to survive and reproduce. Male and female mosquitoes have different feeding habits. Male mosquitoes eat "vegetarian" and specialize in plant nectar, fruits, Feeds on the sap in stems and leaves. Female mosquitoes occasionally taste plant juices, but once they mate, they must feed on blood. Because it can only develop its ovaries after sucking blood. Therefore, only female mosquitoes bite human blood.

There are many whorls of sensory hairs distributed on the mosquito's pair of tentacles and three pairs of steps, and each sensory hair is densely arranged with round or circular pores. In the dark night, mosquitoes can use this sensor to sense the carbon dioxide emitted by the human body in the air, respond within a thousandth of a second, and fly to the blood-sucking target accurately and quickly. Before sucking blood, mosquitoes inject saliva containing anticoagulants under the skin to mix with the blood, turning the blood into thin plasma that will not clot. Then they expel the undigested old blood and suck fresh blood. If a person is bitten by 10,000 mosquitoes at the same time, they can suck all the blood from the human body.

The main harm caused by mosquitoes is the spread of diseases. According to research, there are more than 80 types of diseases spread by mosquitoes. No insect on earth is more harmful to humans than mosquitoes.

There are more than 2,000 kinds of mosquitoes in the world, and there are about 140 kinds in my country. Mosquitoes that can transmit diseases can be divided into three categories: one is called Anopheles mosquitoes, commonly known as Anopheles mosquitoes, which mainly spread malaria. The other type is Culex mosquitoes, which mainly spread filariasis and Japanese encephalitis. The third type is called Aedes mosquitoes, which have black and white markings on their bodies, also called Aedes mosquitoes. They mainly spread Japanese encephalitis and dengue fever.

Eradicating mosquitoes is an effective way to prevent and reduce diseases. Everyone takes action to clean up rivers, garbage and other places where mosquitoes tend to breed. Modern technology also has electric mosquito-repellent coils and other mosquito-killing products and appliances. In the future, we should invent a new generation of mosquito-killing devices to eliminate mosquitoes and prevent mosquitoes from spreading diseases and harming humans.

Female Mosquitoes:

Mosquitoes are ubiquitous and can be found anywhere in the world. There are more than 2500 species of them. It’s a safe bet that you’ve encountered at least one species of mosquito somewhere.

No one likes mosquitoes. But unfortunately she may decide to "like" you. she? Yes, it's her.

Did you know that only female mosquitoes bite humans? However, it is true. This is not because she is unfriendly, but because she needs blood to reproduce.

Do you know how female mosquitoes choose who to bite? She is very selective and picks her victims carefully. First, she uses sensors on her two antennae and three pairs of legs to find bites, and uses these sensors to detect your body's humidity, heat, and chemicals in your sweat. If she is not interested in you, she will leave you and find someone more interesting. Next time you get stung, remember that you were specially chosen.

If a mosquito likes you, she will land gently on your flesh and prick your skin with the tip of her beak. What is the tip of the beak? This is a mouth that grows just below the mosquito's eyes. It consists of 6 sharp instruments called stylets. She inserts all 6 needles into your skin. If it hits a blood vessel, she'll have a full meal within 1 minute. It all happens so quickly and so silently that you might not realize anything is happening.

Why do mosquito bites make it itchy? The itch is not caused directly by the bite. It comes from mosquito saliva. The mosquito relies on this saliva to mix with your blood so that the blood does not clot when it is sucked into the tip of its beak. When you feel itchy, she has flown away.

What happens next? Mosquitoes get tired after a heavy meal. All she needed was somewhere to rest. With your blood heavy on her, she pecks a spot on a leaf or a wall or a stone to quietly lay her eggs. One drop of blood can reproduce hundreds of eggs.

Where is her spouse now? Their relationship has ended, and the male mosquito no longer hangs around the female mosquito. They mate before the female mosquito bites you. After that, the female mosquito can live for 1 to 2 months. During this time she lays eggs 4 to 5 times.

All mosquitoes, male and female, spend their early development stages in or near water. In fact, although mosquito eggs can survive for up to five years on dry land waiting for water, they will not hatch without water. It’s no wonder why there are so many mosquitoes after heavy rain.

But why did nature bother to create mosquitoes? Is it just to annoy us? This is probably not the main reason. Male mosquitoes live on nectar, and some scientists believe they pollinate flowers as they fly from flower to flower. Of course, mosquitoes have to breed and unfortunately get you and me involved. Like it or not, mosquitoes are here to stay.

Ovulating women are the favorites of mosquitoes:

As we all know, mosquitoes rely on scent to find prey and mates. A unique pheromone emitted by female mosquitoes can attract male mosquitoes from a kilometer away. However, few people know that ovulating women are also highly attracted to mosquitoes.

Mosquitoes are interested in ovulating women not because their blood is sweet, but because of the nearly saturated fat in their blood. In addition to being particularly fond of ovulating women, mosquitoes also show great interest in people of both genders who have high blood cholesterol levels.

Mosquitoes like to hunt in swamps at dusk, because such temperature and humidity are the most ideal conditions for their species to breed. According to research by German scientists, mosquitoes can smell the scent of prey from a kilometer away, especially women during the ovulation period who are most "cared for" by mosquitoes. This shows that what mosquitoes love most is blood full of fat, rather than the "sweet" blood (blood with high glucose content) that people have always thought. The research results of American entomologist Jerry Butler published in a German magazine also showed that people with higher blood cholesterol levels are also the most attracted to mosquitoes. Unfortunately, scientists are still unable to explain how mosquitoes sniff out cholesterol levels in the human body.

In addition, during the research process, scientists also found that it is this type of people who are particularly good at attracting mosquitoes who often have allergic reactions to mosquito bites, which means that they have been bitten by mosquitoes. The area is often congested or itchy.

However, scientists have not yet developed a new set of effective measures to combat mosquito infestation, so their advice can only be to advise you not to go naked and to take some mosquito repellent to prevent this incessant pestering. "Vampire".

To avoid mosquitoes in the home environment, you should do the following:

1. Check the pots, pots, floor drains, sewers, flower pots, etc. in the home where there is water accumulation and have lids. If you can, change the water frequently. Prevent water accumulation in floor drains, sewers, etc., and spray insecticide frequently to prevent mosquitoes from living.

2. The water of aquatic plants at home should be changed regularly.

3. Be careful to close the screen windows and screen doors, and do not leave the door wide open to allow mosquitoes to drive in.

4. Do not litter cans, mineral water bottles, egg shells and other garbage that is prone to water accumulation. It is best to use lidded trash cans.

5. If you are on a business trip or away from home for a long time, cover the toilet lid and drain the water in the sink and pool to prevent mosquitoes from laying eggs.

Three major factors why mosquitoes bite you:

First, the carbon dioxide exhaled from the respiratory tract is the source of odor for mosquitoes. Mosquitoes use this to find people and then bite them.

The second is heat. Fat people are more likely to be bitten by mosquitoes. Dark clothes absorb heat and attract mosquitoes.

The third is excrement. Mosquitoes love to bite people with rough pores and sweat a lot. Generally, men are more attracted to mosquitoes than women, young people are more attractive than old people, and healthy people are more attractive than sick people because there are more secretions on the skin surface. Children have a strong metabolism and are favored by mosquitoes. In addition, when women have their period, their secretions change, which attracts more mosquitoes. After you sweat during exercise, you will be more attracted to mosquitoes. Therefore, experts suggest that it is best to take a shower quickly after exercise. The less you sweat, the less mosquito bites you will get.

Four tips for preventing mosquitoes in summer:

1. It is best to use less soap when taking a bath in summer. Generally speaking, mosquitoes like to eat flower nectar. Therefore, the probability of being bitten by mosquitoes will increase after using perfumes, cosmetics, facial creams and other items with floral scent. However, not all fragrances will attract mosquitoes. For example, the cologne commonly used by men has a sandalwood scent, which can actually repel mosquitoes.

2. Eat more vegetables. Some vegetables contain odors that mosquitoes don't like, such as vegetables containing carotene and spicy vegetables such as garlic. After people eat them, mosquitoes will stay away from you.

3. Wear light-colored clothes. Aedes mosquitoes (also called Aedes mosquitoes) like to stay on black clothes.

4. Try to wear socks. Many girls like to wear shoes barefoot, but they don't know that after wearing socks, mosquitoes feel that the humidity of human skin is reduced and the volatiles on the skin surface are reduced, which will reduce bites.

Mosquitoes love to bite blondes:

Some mosquito experts pointed out that mosquitoes, like many men, prefer blondes. Once you are bitten by mosquitoes, do not try to move them away, as doing so will only stimulate their appetite.

Spielman, an expert on mosquitoes and mosquito infectious diseases, said that people with blond hair and red hair are particularly attracted to mosquitoes simply because they always stand out from the crowd.

Spielman said: "Mosquitoes are easily attracted to things with strong contrast. If there is a group of people picnicking in the shade in the countryside, one of them has long blond hair and wears bright clothes, and the others are all dark-colored. Colored hair, you also know who attracts the most attention.

“There are always some people who are more likely to be bitten by mosquitoes, and the related reasons are not yet clear. However, many studies have shown that it may be related to skin temperature, color contrast, lactic acid, etc. ”
