It's more true 丨 I haven't been bitten in the summer, eight bags in autumn, and mosquitoes in autumn are even more illusory.

Summer has passed, and the north has begun a staged cooling mode. Everyone has begun to relax mosquitoes and feels that there is no need to worry about mosquitoes when they are autumn, but in fact, many netizens said, "The whole summer has not been bitten. After being bite, he was bite. " Why is "autumn mosquito fierce as a tiger"? Is the mosquito bite really looking at the blood type? Take these six knowledge points to help you deal with mad mosquitoes after autumn.

1. "Mosquitoes in autumn are like a tiger"?

This makes sense. Mosquitoes are completely perverted insects, and their lives need to go through the stages of eggs, larvae, pupae, and adults. And their eggs and larvae are usually inseparable from the water environment, which means that the water condition in the environment is closely related to the growth and development of mosquitoes. In my country, China's climatic conditions, static water conditions, and types of mosquitoes will not be exactly the same. Therefore, the main periods of mosquitoes in various places will also be different. Taking the Guangxi area as an example, the mosquitoes in this place are mosquito, and September and November each year are the high -density periods of the high density of mosquito groups in Guangxi each year. Gao Feng, naturally dingling people will be more frequent. In addition, some mosquito insects can overwinter in the form of adults. They usually try their best to eat more blood before wintering to maintain the normal life activities in winter, so it will make people feel that their bite becomes more violent than usual. That is, "the mosquito in autumn is like a tiger."

Second, only female mosquitoes can bite people. Do not worry about male mosquitoes?

This is true. The mosquitoes we are discussed here usually refer to insects-insects of insects-winged eyes-long-hornya-mosquito family. There are many members of this department and are widely distributed worldwide. At present There are as many as 4,000 kinds of mosquito members recorded in my country. A considerable part of these mosquitoes are bloodthirsty creatures. Their female adults need to rely on the blood of people or other animals to obtain the necessary nutrients that maintain life activities and reproduction. They can cause great popularity such as malaria such as malaria in many areas (in tropical areas). Even if humans are bitten by female mosquitoes that do not carry pathogens, it is easy to produce discomfort such as itching, mass, dermatitis and other unsuitable infections. Therefore, female mosquitoes are really miserable. The male mosquito adults usually do not have a mouthful of piercing skin, so they can only suck nectar or other liquid quality, and they are not interested in blood. Therefore, the mosquitoes of the dongs are indeed female mosquitoes.

Third, shooting a winter mosquito is equivalent to destroying thousands of "mosquito second generations"?

It makes sense. The growth and development methods of different mosquito insects are different from the life cycle of life. Some mosquitoes (such as light -colored library mosquitoes) can exceed winter in the form of adults, that is, enter the stagnation period in adults (then the temperature and humidity in the coming year in the coming year in the coming year will be in the coming year. Wake up when it is suitable), mosquito individuals in this state are called overwintering mosquitoes. Related research literature shows that the number of individuals of wintering mosquitoes will directly affect the number of mosquito and population density in the following year, so the number of overwinter mosquitoes is important for reducing local mosquito damage and preventing and controlling infectious diseases that cannot be ignored. Therefore, killing a winter mosquito is equivalent to eliminating hundreds of thousands of first -year mosquitoes. This is also the main reason why many mosquito -raging severely disaster -stricken areas to organize large -scale spraying mosquitoes every autumn and winter seasons. Usually, humid and warm dark places in indoor and outdoor are the key targets of killing mosquitoes.

Fourth, mosquito bite people to see blood type?

From the overall macro perspective, this sentence is not necessarily established. There are a small amount of research literature that some specific types of mosquito insects will have a more obvious tendency for some types of blood, such as some types of Iraqi mosquitoes prefer O -type blood. However, it should be noted that the experimental design and sample selection range of these studies have certain limitations, and the types of mosquito are strictly controlled, the research area, and various environmental variables need to be strictly controlled. These specific tendency environment and biological mechanism discussions do not have sufficient universality. It is certain that changes in the physical condition of the regional environment, the type of mosquito, and the physical condition of the experimental individual will have a significant impact on the bite preferences of mosquitoes. In most areas, most of the raging mosquitoes are more than one, and the metabolism level and cleanliness of different people in the environment are different. In fact, the situation of these variables on the choice of mosquito choices is much higher than the difference between blood types. The effect of blood type will be revealed only under certain circumstances. Therefore, if you want to prevent mosquitoes, do a good job of personal cleaning, and choosing the right mosquito repellent supplies is the key. Ordinary people do not have to pay special attention to whether their blood types are recruited.

Fifth, people who love sweating are more likely to be bitten by mosquitoes?

It makes sense. Evergreen animals like humans will emit some unique flavors when they move in nature (the exhaled carbon dioxide and the smell of body surfaces, etc.), and female mosquitoes are mainly relying on their own tentacles when searching for bite targets (smell of smell (smell sense of smell Feels) to recognize the relative orientation of the source of qi. Therefore, many mosquito -like products also use this physiological characteristics of mosquitoes to play a role, such as the main action mechanism of chemicals such as Diethyltoluamide (DEET) such as mosquito. Strong dislikes to achieve the effect of avoidance). People who love sweating are usually relatively more obvious. In addition, the evaporation of sweat will leave a lot of odor signals in the air to capture mosquito, so it is naturally more likely to be regarded by female mosquitoes as the target of blood -sucking.

6. It is easier for mosquito to wear dark clothes?

It makes sense. Generally speaking, many insects (especially at night activity insects) have a certain degree of light, and different types of insects have their own preferred light wavelengths. It is reflected in macro. s color. According to relevant experiments, the attractiveness of black objects to mosquitoes is mostly in the middle, that is, it is not particularly preferred and will not be far away, and the color preferences of different types of mosquitoes are not exactly the same. However, usually black clothes under the scorching sun are easier to absorb and increase the temperature of the body surface than other colors, which will increase the evaporation of sweat and improve the spread of the dressing person's body taste. Therefore, wearing dark clothes is more likely to be bitten by mosquitoes in some cases.
