In the summer, the weather starts to get a little hotter and mosquitoes start to increase. Although it is a rural area, when it comes to mosquitoes, it is actually no less than the city. However, there may be more mountain mosquitoes here, and the city is mainly black-headed mosquitoes.

The mountain mosquito, which is what everyone calls the flower mosquito, is really called Aedes albopictus albopictus mosquito, also known as the spotted mosquito. This kind of mosquito is very powerful, and it is much more ferocious than the one in the city.

They mainly suck blood during the day, bite ferociously, and transmit dengue fever, known as the "Asian tiger mosquito". It breeds in natural stagnant water and small containers, such as jars, cans, canned food boxes, flower beds, bamboo tubes, tree cavities, lunch boxes, waste 1-day tires, bonsai, blocked rooftop ditches, etc.

The spotted mosquito bites and sucks blood at night and during the day. The spotted mosquito is not only vicious, but also good at flying. Generally, mosquitoes only fly tens to hundreds of meters, and the farthest is not more than 1-2 kilometers, but the spotted mosquito can fly 5-7 kilometers, and the speed is extremely fast, and it can also do "difficult actions" such as rolling back and forth, diving, sharp turns, sudden acceleration or deceleration at will.

So, in the countryside, mosquitoes are even more terrifying. In the past two days, there have been a lot more flying squirrels in front of and behind the house, all of which are aimed at mosquitoes.

"The mosquitoes here are so powerful, this bite is just a big bag, and it's very itchy." Zhou Furong was very depressed and slapped himself suddenly. However, the mosquito reacted very quickly, and it couldn't be photographed at all, but it hurt itself.

The others smiled, and they didn't know why, Zhou Furong was particularly annoyed by mosquitoes. Everyone sits together, and those mosquitoes always like to bite him.

"Who called your meat fragrant? We don't ding, what can we say? Chen Wu said with a smile.

"I've heard that it seems to have something to do with blood type, and they love one blood type or another." Li Quan said.

Professor Wen shook his head, he is an expert in this area, and naturally he has the most right to speak. He told everyone: "For a long time, there has been a debate about why some people are more likely to be bitten by mosquitoes. In fact, mosquitoes do not distinguish between blood types. However, as we perceive, mosquito bites do have a preference. Mosquitoes want to eat not blood, but sugary substances, and the reason why mosquitoes bite is just to improve their fecundity. ”

After Professor Wen finished speaking, Fu Shenglin continued: "The blood contains substances that make mosquito eggs mature, and if your blood is rich in cholesterol or vitamin B, female mosquitoes will like you more." The 'chemoreceptors' on its tentacles are the tools to find you. ”

Like sweating, the acidity in the blood is enhanced, and the sweat discharged makes the body surface lactate value high, which is attractive to mosquitoes. In addition, there is a heat receptor in the antennae of the mosquito, which is very sensitive to temperature, as long as there is a slight temperature difference, it can be immediately noticed, and the sweat enters the body to dissipate heat quickly, which will also have an attraction to mosquitoes.

Mosquitoes search for prey by smell. Carbon dioxide has a strong attraction to mosquitoes. Mosquitoes have carbon dioxide receptors on their small tentacles, which can sense carbon dioxide, lactic acid, and other substances. The carbon dioxide released in the exhaled breath can be detected by mosquitoes from a distance of 15 meters.

After engaging in sports or physical labor, the breathing will be accelerated, and the exhaled carbon dioxide will be relatively large, and the carbon dioxide gas will form a moist and warm air flow about 1 meter or so on the head, which mosquitoes are more sensitive to and will smell it. In the same way, those with a large lung capacity or a faster breathing rhythm also have more carbon dioxide in and out, and mosquitoes will swarm when they smell it.

In addition, because black is the first choice for mosquito attacks, such as Aedes mosquitoes, they prefer to stop on black clothes. The second is blue, red, green, etc., mosquitoes do not like to bite in white clothes. In the same way, mosquitoes love to bite darker or reddish skin. Professor Wen spoke.

After hearing this, Zhou Furong was stunned for a moment, and then said loudly: "I said, why are you so provoking mosquitoes today!" It turned out that it was all the clothes to blame. ”

Everyone saw that the guy was wearing black today, except for black pants, and a black vest on it.

"It's not all about clothes, it's about other aspects of you. You are fatter, so your sweat glands are well developed and you are prone to attracting mosquitoes. Fu Shenglin said with a smile.

"No, I've got to get some toilet water, or I won't be able to get through tonight." Zhou Furong hurriedly went to find the flower water. In the city, everybody uses that.

"Huh! Flower water repells mosquitoes to a certain extent, but it is not useful for mosquito bites. Moreover, the toilet water may still be effective against mosquitoes in the city, but it may be less effective against mountain mosquitoes. Professor Wen immediately spoke to Zhou Furong.

Professor Wen didn't deceive him by saying this, the flower water is mainly sold to the city, and it is aimed at the black-headed mosquitoes in the city, for these ferocious flower-headed mosquitoes, "What should I do?" Zhou Furong immediately glared.

"Simple! Use sliced garlic to repeatedly apply it for a few minutes at the mosquito bite, which has obvious pain-relieving itching and anti-inflammatory effects, even if the bite has become a big bag or is inflamed and ulcerated, you can use garlic to rub it, and it will be good soon. Of course, if you have sensitive skin, you should use it with caution. In addition, it will be much better to wash it with laundry detergent water. Chu Jiaqiang said with a smile.

Mosquito repellent, that's even easier. In the countryside, everyone uses some herbs to get rid of them.

"This mosquito is definitely male! So powerful! When Zhou Furong saw it, his hand stopped again, and he immediately slapped it hard.

"Then you are wrong again, male mosquitoes generally do not suck blood, only female sucks blood!" Fu Shenglin said to him.

The antennae of male mosquitoes are filamentous, and the antennal hairs are generally thicker than those of female mosquitoes. Their white spoon food is nectar and plant juice. The mouthparts of male mosquitoes are degenerated, and female mosquitoes need to bite animals to suck blood to promote the maturation of internal eggs before breeding.

"Why don't you just wear long sleeves? That won't bite you. Xu Bimei said to him.

Professor Wen shook his head and explained to everyone again: "It's not because there is an extra layer of cloth on the body, mosquitoes can't use mouth needles to suck blood. In fact, the mosquito's mouth needle is so sharp that it can penetrate even cowhide and thick jeans, and the clothes worn in summer are not "bite" at all. The main function of clothing is to mask the smell of skin secretions such as sweat, so that mosquitoes cannot track them. ”

Chu Jiaqiang went to the house, took out some herbal powder, smoked it with fire, and the faint fragrance of herbs came out. If you look closely, you will find that the mosquitoes began to fly towards the herbal smoke, and then staggered like drunk.

"What the hell did this come about? Much easier to use than mosquito coils. Everyone was amazed.
