Night,"Buzz. "The mosquito sound is the most annoying, ghostly and relentlessly following you, planting you big and small red envelopes, but as soon as you wake up and turn on the light, it disappears.
Why are mosquitoes so arrogant? It turns out that its ancestors existed hundreds of millions of years ago, and the earliest Australopithecus was only 5 million years old.
It can be said that mosquitoes have accumulated more survival experience than we have ever eaten rice. So despite our best efforts, even with the help of genes, humans are still very passive in front of mosquitoes.
It's a season of sin for little ones. Parents who have little babies at home must find a way to help their babies do a good job of mosquito repellent. Because mosquito bites not only make babies itchy and unbearable, but also can transmit various diseases.
The resistance of young children is relatively weak, and it is easy to cause mosquito bag infection after scratching, and it may cause fever in children, so we must pay attention to it.
A few days ago, a friend's baby was bitten by a mosquito on the face of a big bag, and it looked funny and distressed:
The mosquito army began to wreak havoc; , pediatric surgeons reminded parents:Infants and young children are prone to more serious symptoms after being bitten by mosquitoes due to their delicate and low immunity.
In fact, mosquitoes existed for hundreds of millions of years before humans came into the world.
According to the discoveries of archaeologists, the ancestors of mosquitoes are inCambrianIt came into existence at the time of the Great Explosion of Life, in the form of flying (diptera) arthropods.
In the late Cretaceous period, the impact of meteorites and the vicious changes in the climate were as strong as dinosaurs were shattered, and the mosquitoes that I thought were annoying were not spared, but I never thought that they would survive and continue to evolve!
It has a very short lifespan, 3 to 10 days for males and 10 to 20 days for females.
Dialogue between male and female mosquitoes in just adults).
It's small, flickering, and weighs about 2 25mg, which is more than 40 times lighter than a grain of rice, and only weighs about 0 on one hind leg25mg。
It's a flying insect insideThe slowest flying animal, the flight speed is about 15 to 25 km, more than 10 times slower than a camel crawl.
If you can't fight mosquitoes, it's not that you haven't been single long enough! That's because mosquitoes have a lot of flying skills, can hover, suddenly accelerate and decelerate, and especially like to fly up and down.
Syllable. It can't escape the palm of my hand after all
It has six needles in its mouth, two of which are responsible for cutting the victim's **, two for propping up**, one for injecting anticoagulants, and one for sucking blood.
And it's not sucked as soon as it comes up, it needs some foreplay, first cut through the **surface, and then two needles open the two sides of the scratch:
Rub it for a while, find the location (I mean find the location of the blood vessel), push hard, prick the needle to release the anticoagulant, and then prick the needle to start sucking blood:
Greedy mosquitoes, in order to suck more blood, urinate to make room in the process of sucking blood:
After the mosquito has finished urinating, it will react: it turns out that a mosquito has bitten me!
After watching the process of mosquito bites, is it very infiltrating? There's something even more terrifying:
It is the largest killer in the worldMore than 72 people die each year50,000 people！Because mosquitoes are one of the main ways to transmit infectious diseases with high mortality rates, such as dengue fever, malaria, yellow fever, sleeping sickness, etc.
1.By Vision:For mosquitoes, if they are far away, they will not use their own vision, and only when they are close to the situation, they will use their own vision. According to research, mosquitoes are more sensitive to darker objects.
2.By the perception of temperature:Mosquitoes have a very powerful temperature sensing function, and the objects moving around them can be accurately analyzed: humidity, temperature and air temperature, and finally lock on to their own blood-sucking objects.
3.By your own sense of smell:Our human body secretes a lot of chemicals every day, and these substances will slowly turn into air currents and then emit out, and in the process of dissipation, they will be smelled by mosquitoes.
1. The baby sweats a lot
Compared with adults, babies have a more vigorous metabolism and are more likely to sweat. Mosquitoes' antennae have a strong sense of smell, and they are unusually sensitive to the smell of sweat.
After the child sweats, the mosquito will find the baby's body through the small molecules of sweat in the air, so the baby who loves to sweat is more susceptible to mosquito bites.
2. The baby has a milky fragrance
Many babies have a milk scent, which will attract the attention of mosquitoes, and if the body lotion or talcum powder that the mother usually uses for the baby has a fragrance, it is easy for mosquitoes to find the door along the smell.
Therefore, after bathing, mothers try not to use scented skin care products for their babies.
3. The baby lacks the ability to be prepared
The smaller the baby, the less sensitive, and sometimes the mosquito bites for a long time, and the child seems to have no feelings. When the bite has passed, a child reacts to the uncomfortable feeling.
Since a child does not do anything when it is attacked by a mosquito, mosquitoes are more likely to bully the child.
Therefore, compared with the sensitivity and defensiveness of **, mosquitoes prefer small babies.
1. Women who love makeup
Cholesterol and vitamins are two substances that are necessary for the survival of nasty insects such as mosquitoes and cannot be produced on their own.
Stearic acid (required for cholesterol synthesis) is found in most cosmetics, and the use of floral-scented cosmetics such as perfumes, hairsprays, and creams increases the chance of mosquito bites.
So women who love makeup have suffered, so how can they avoid it? One is to avoid using irritating cosmetics in places where there are more mosquitoes at night, and the other is to do a good job of mosquito prevention.
2. People who love to drink
Studies have shown that after drinking alcohol, people will undergo some changes in body odor and breathing, and the smell of alcohol emitted is particularly susceptible to mosquito bites.
Moreover, after drinking, the body's immunity decreases, and after being bitten by mosquitoes, it is easy to become infected due to insufficient resistance.
So if you like to drink more or have just finished drinking, try to go home and rest, and don't go to areas with more mosquitoes, after all, in addition to mosquitoes, the chance of danger after drinking is also quite high.
3. Pregnant women should pay special attention to mosquito prevention
Mosquitoes can accept and love any type of carbon dioxide. They can feel the scent of carbon dioxide even from a distance, and then they salivate and rush over ......
Pregnant women may exhale higher levels of carbon dioxide than the general population. Zika virus has been circulating in some tropical countries in the past two years, and expectant mothers should pay special attention to mosquito prevention.
If you're one of them, you need to be careful, because mosquitoes don't just cause itching and rednessIt may well cost you your life
In spring, the temperature generally rises slowly, and mosquitoes are insects of the class Diptera mosquitoes in the phylum ArthropodsPrefers warm and humid environments.
There are mainly four stages of eggs, larvae, pupa and finally adult mosquitoes, and there are mosquitoes in spring, because the temperature rises, and the surrounding environment is relatively humid to meet the needs of mosquitoes for growth and reproduction, resulting in a large number of mosquitoes.
The lifespan of mosquitoes is generally relatively short, mosquitoes are divided into female mosquitoes and male mosquitoes, generally female mosquitoes have a longer lifespan, about 3-100 days or so, and die after one to two months after mating.
The life span of male mosquitoes is shorter, about 10-20 days or so, and they will die after 7-10 days of mating, and mosquitoes can be divided into four stages, namely eggs, larvae, pupa, and adults; After becoming an adult, the female mosquito sucks blood to promote egg laying.
Spring is a thriving season, the earth is rejuvenated, everything begins to recover, especially after the Qingming Festival, mosquito activities are more frequent. MoreoverThis climate is suitable for breeding. If you pay attention, you will find that mosquitoes will multiply in places with sewage and rancid matter.
"Kill an overwintering mosquito and eliminate a second generation of mosquitoes. ”
If you want to have a comfortable summer, you must start to do a good job of mosquito control from the spring to protect the health of your family.
The weather is getting more and more people, and there are more "poisonous mosquitoes", whether it is indoors or outdoors, we must do a good job of mosquito prevention and mosquito repellent, and stay away from the spread of the virus!
In fact, in order to deal with mosquitoes, people also use many similar methods, such as mosquito nets, mosquito coils, electric mosquito liquid, and so on. But in this protracted "human-mosquito war", because the mosquitoes are so large and almost ubiquitous, humans always seem to be at a disadvantage.
Of course, mosquitoes are not without natural predators, such as bats, birds, fish, etc., will feed on mosquitoes, but because the number of mosquitoes is too much,And these animals don't just eat mosquitoes, so for mosquitoes, it's basically painless.
Scientists have tried a variety of methods to eradicate mosquitoes, but at present, there is almost no way for humans to completely eliminate mosquitoes. Mosquitoes are a typical representative of the "millennium of scourge"!
And even if we put aside whether we can completely eradicate mosquitoes, even if we can, we can't just wipe out a species. Scientists are also only hoping to eradicate the mosquitoes that can spread diseases on a large scale, not all mosquitoes.
Even if the mosquito seems to be useless, it must have a reason for its existence in the ecological chain, and perhaps it exists to control the animal population by spreading diseases.
But then again, although it is difficult to eradicate the "poisonous mosquitoes" around the world, the poisonous mosquitoes in our own homes must be eliminated, and no one wants to be in the same room with mosquitoes!
