Speaking of flower mosquitoes, I think of my childhood. At that time, in summer, my family would enjoy the cool in the yard. I don't remember when the famous flower mosquito spread. Later, people who were tortured by flower mosquitoes stopped going outside to enjoy the cool.
According to the data, the scientific name of the flower mosquito is Aedes albopictus, and there are black and white stripes on its body and limbs, so everyone calls it "flower mosquito". Moreover, this black and white pattern is somewhat similar to that of the tiger, so it also has a nickname "Asian tiger mosquito".
Compared with ordinary mosquitoes, flower mosquitoes are really poisonous. I don't think people who haven't been bitten by mosquitoes should exist. Being bitten by ordinary mosquitoes is actually not a big problem. Like my mosquito-attracting physique, I can hardly feel bitten by ordinary mosquitoes, but flower mosquitoes are not so kind. If you are bitten by a flower mosquito, you will get several bags at once, and it will be itchy and will not disappear for a while. I remember being bitten by a flower mosquito.
In order to better suck blood, flower mosquitoes will release some substances when they bite, such as thrombin and formic acid. As I said at the beginning, these substances are foreign bodies to the human body, just itchy bags on the human body, which are actually allergic reactions.
? Some people don't understand why flower mosquitoes can be so poisonous. There are several reasons. ：
First, the biting method is clever.
How do ordinary mosquitoes bite? Everyone should know that it is very greedy. If you don't slap it and pat it, they will keep sucking blood, so full that they can't fly. It's really amazing. I told you not to overeat.
Then mosquitoes will briefly enter the rest stage and slowly digest the sucked blood.
The biting mode of flower mosquitoes can be said to be an upgraded version of ordinary mosquitoes. The flower mosquito will "repeatedly bite", and it is still not easy to shoot it to death. Now do you understand why there are several bags after being bitten by a flower mosquito? It turned out to be a bite.
Why can flower mosquitoes be so active? Because they have a strong digestive ability, it is not a problem to digest while sucking blood.
And they are very smart, and they don't have enough to eat every time, so the flower mosquitoes basically have no rest when they move. They find someone to bite them during the day and at night.
No one doesn't hate such poisonous flower mosquitoes that don't rest and bite repeatedly.
Second, the body structure is ingenious.
Judging from the structure of the mouth, the flower mosquito, like many mosquitoes, can be described as exquisite. However, it has six "needles" in its mouth, each of which performs its own duties. Every time they bite us, these needles will do different things to ensure the smooth operation.
The left and right oral needles have no blood sucking effect, such as the hand brake of a car, which is used to fix the mosquito's body. How to fix it? Two needles cut the skin, so that the mosquito's body is fixed on our skin.
Then the flower mosquito embeds two needles in the middle of the mouth into the skin and looks for blood vessels everywhere. After finding the blood vessel, it sucks blood with the thickest oral needle.
Such a needle tube structure can complete the role of blood sucking very invisibly, and at the same time ensure its own safety.
Moreover, when biting, saliva and enzymes will be released, which can inhibit platelet coagulation, and mosquitoes can rest assured. Also, when cutting skin, flower mosquitoes will produce an anesthetic substance, so we won't feel pain.
At the same time, their mouths are idle and they secrete a lot of acidic substances, which is also the reason why they itch after being bitten. Because flower mosquitoes release more acidic substances than ordinary mosquitoes, they are not only red and swollen, but also extremely itchy. Severe cases may cause local or systemic dermatitis, which is easy to be infected by hand.
Third, carry the virus itself.
This is related to the environment that flower mosquitoes like. They generally like dirty and humid environment, naturally easy to carry viruses, easy to spread to humans through bites. According to a statistical data of American scientists, at that time, about 70% of the blood of flower mosquitoes was from mammals, about 20% from birds, and about 10% from rabbits.
Anyway, flower mosquitoes can suck as long as they meet blood. You can imagine how many viruses they carry in their bodies. Do you think it's horrible?
According to the statistics of relevant institutions, there are many viruses that can be transmitted by mosquito bites, such as Japanese encephalitis, yellow fever, Ross River fever, West Nile virus, dengue fever and so on.
Moreover, the spread range is wide and the spread speed is fast, resulting in a large number of patients and very serious harm.
Flower mosquitoes not only suck blood, but also bring such serious health risks, which is really hateful.
Do you know that?/You know what? The harm of flower mosquitoes is recognized in the world, and now there are flower mosquitoes all over the world. In 2008, the flower mosquito was awarded the title of "one of the most serious invasive species in the world 100".
? How did the flower mosquito get into China? ?
The origin of the flower mosquito is the tropical region of Southeast Asia. Since the 1960s, global trade has become more and more frequent. Flower mosquitoes take the opportunity to develop their own territory. First spread in Asia, the route is journey to the south.
In the 1980s, it invaded China. According to relevant research, the biggest reason why the flower mosquito can come to China is the frequent trade activities, which is equivalent to providing the flower mosquito with a means of transportation for long-distance navigation.
At the same time, a large number of invasions in Europe and America caused great damage. 1990 was first discovered in Africa, and 199 1 year overflowed.

Reliable anti-mosquito coup? ：
1, physical way, mosquito net
A direct and rude way, regardless of anything.
2. Mosquito repellent and insecticide.
This is the most scientific, but mosquito repellent usually lasts about 5 hours, and some people don't like the taste. As for pesticides, you can choose mosquito-repellent incense, put a plate at 2 o'clock before going to bed, then close the doors and windows, and open the window to breathe when sleeping.
Step 3 clean up mosquito larvae
Mosquito larvae generally live in water, so pay more attention to stagnant water, such as sinks, faucets, washing machines, bottles and cans. Clean up the accumulated water in time to eliminate mosquitoes from the source.
Step 4 wear light clothes
Scientific research shows that mosquitoes like dark colors, especially black, which attracts them very much.
Rumors about anti-mosquito tactics? ：
1, acoustic mosquito repellent software
Mosquito repellent applications cannot emit ultrasonic waves. Mosquito repellent is bullshit There is only one function, and that is power consumption.
2. Mosquito repellent
Experiments show that mosquitoes don't like this kind of plants, and geraniol, citronellol and other substances do have certain effects, but the effect is very small, which is equivalent to ineffectiveness.
Well, I think we have discussed all the problems. Is it comprehensive? Don't be careless about mosquito control. Usually, you have to install screens on the windows. You can use a little toilet water and mosquito repellent. Although it can't completely eradicate mosquitoes, it is definitely good for mosquito control.
