Mosquitoes are common insects that can be found everywhere. But their appearance nearby immediately causes an unpleasant feeling, because the parasite bites strongly, and after the bite, a red spot remains, which itches a lot.
And this is not all the troubles that mosquitoes cause, they suck blood, use it for reproduction.
When bitten, dangerous infections can be introduced that can cause serious health complications. Such a small insect, but how many troubles it causes. And yet it is worth knowing the characteristics, features, including indicators of life expectancy.
General information
The mosquito is a miniature insect with a pair of transparent wings, six long legs and a proboscis, with which it is fed. The body consists of the cephalothorax, where the internal organs are concentrated. The elongated abdomen serves to concentrate the blood received by the insect from the victim's body.
Mosquitoes are truly unique creatures. They inhabit all over the globe. The only exceptions are the Antarctic latitudes, where the life of a mosquito becomes impossible due to too low temperatures of the surrounding space, the lack of conditions for food and reproduction of offspring. In total, researchers have registered about 3,000 individual species of mosquitoes.
Mosquitoes: annoying bloodsuckers
Mosquitoes ... These annoying insects are familiar to everyone, and communication with them gives pleasure only to one of the parties - the mosquito. They will get it both in the deep forest and in the "stone jungle" of the city; their characteristic high sensitivity is present due to the specific organs of smell - antennae, on which 72 receptors are located.
Thanks to them, this small creature is able to hear the smell of sweat for many kilometers. Mosquitoes are also able to see in the infrared spectrum, so you cannot hide from them even under a blanket at night. Publishing a nasty squeak, hordes of such insects ruthlessly attack a person in all corners of the planet (except perhaps Antarctica), who is forced to fight them day and night and look for various methods of protection.
and when will they finally expire? ”.
Mosquito feeding
What makes such insects drink the blood of other living beings? It is immediately worth noting that only females differ in bloodlust in this vast family. And even then this happens only with the onset of a period of active reproduction.
Males are not bloodsucking. They are nourished by flower nectar.
Females enjoy not only human blood. They do not hesitate to stick to any mammals. It has been proven that these insects often feed on the blood of birds and even reptiles.
As you can see, male and female mosquitoes have differences in terms of food choice. For females, blood is not only a source of precious life energy. It is also a storehouse of protein, which is an irreplaceable material for the reproduction of offspring.
According to some people, after drinking blood and laying the larvae in the water, the mosquito will certainly die. In reality, this only happens with starving females. Not finding food, they spend their last energy on creating masonry, deplete their own body, and then die.On the contrary, a well-fed female mosquito processes the blood of its victims into nutrients, which makes it possible for it to remain viable for a long time and lay 200-300 eggs every few days.
When the season starts
Reproduction of blood-sucking insects is observed all summer, but their maximum concentration occurs at the end of the hot season. In August, the daylight hours are shorter, and therefore mosquitoes quickly appear in the evening hours. In central Russia, this month is characterized by humidity and cool weather. It is difficult to find more suitable conditions for the existence of a mosquito.
It is interesting: mosquito insect.
In the Moscow region, the season of winged bloodsuckers falls on the second decade of July. During the day, mosquitoes go without food, hiding in parks and forests. They go hunting at nightfall. It is difficult to designate the time of disappearance of insects.
Much depends on the weather. Usually their number decreases closer to September. Winged insects disappear completely with the arrival of the first frost.
Blood is a favorite food
Blood for the mosquito is the main source of nutrition, supporting the latter with energy and nutrients. This is a kind of storehouse of protein - the building foundation for eggs. Moreover, only females drink human blood, they also feed on the blood of birds, reptiles and animals. It even happens that fish become victims of mosquitoes.
But the harmless males are quite satisfied with the flower nectar. An adult mosquito is able to treat itself to blood in a few hours more than 8 times, so 3-4 mosquitoes flying into the room and attacking their prey seem like a whole horde to a person. Making from 600 to 100 oscillations with their wings per second, they emit a subtle annoying squeak; in males it is much thinner than in females.
How long do mosquitoes live? It is believed that after being saturated with blood, the female mosquito dies; in fact, she "stretches her paws" after laying eggs, and even then in a state of hunger. A well-fed individual replenishes mosquito troops with 20-300 eggs every 2-3 days, leaving them in moist soil or water bodies and setting off after laying in search of daily bread.
Insect lifespan after a bite
The mouth apparatus of the mosquito is fundamentally different from the female, which has sharp canines for piercing the skin and sucking blood from a person or a warm-blooded animal.
Why do mosquitoes bite people?
Some species are capable of feeding on the blood of even fish, birds and amphibians. An unfertilized female, like males, eats exclusively plant foods.
Insects can lay eggs without blood. But in this case, immediately after oviposition, the female dies in one day, and less than half of the weak offspring survives.
Thus, if the source of protein food is in the immediate vicinity, the female will be able to regularly replenish the necessary reserves of expended energy and live her full life cycle after a human bite, that is, at least 4 months.
How do mosquitoes look for prey?
Where does the mosquito come from, or rather, how does it manage to find potential victims, being at considerable distances from them? This ability of a blood-sucking insect is due to the presence of antennae on the head, which play the role of a specific olfactory organ. More than 7 dozen receptors are concentrated here, which makes it possible to recognize the smell of mammals at kilometers distances.
If the female mosquito is a hundred meters away from the intended victim, she can navigate by the plume of carbon dioxide that occurs when the mammal breathes. In addition, these insects have learned to "see" objects in the infrared spectrum. It is for this reason that mosquitoes find their prey in pitch darkness without unnecessary problems.
And what about in winter?
Mosquitoes are most active in summer, especially if it was wet.In autumn, their number becomes noticeably smaller, and by winter they completely disappear from the field of view. Where do mosquitoes hibernate and how do they cope with this time of year?
In fact, you should not worry about little bloodsuckers, since they are able to winter calmly, and at every stage of their development. Eggs, pupae, larvae, and adults retain their full viability in the cold months. They equip themselves with nests in secluded places, which will not be penetrated by frost and freezing wind. These places are:
- hollows of trees;
- cavities under the bark;
- burrows of animals;
- dry caked grass;
- cracks in houses;
- places under stones.
And if you're lucky, mosquitoes in winter can settle in special conditions. These include places created by man, for example, basements, cellars, vegetable stores, outbuildings and, in fact, apartments and private houses. In the latter case, insects do not even break their habitual diet, continuing to feed on the blood of people and animals.
On a note! Some tropical species are able to survive the winter under the ice, and with the arrival of the warm season, they "thaw" and rise into the air in a multimillion blood-sucking cloud. For this reason, spring and summer are especially difficult seasons for the inhabitants of the tundra!
In temperate and northern climates, little vampires endure the winter in a state of diapause, or, in other words, hibernate. At this time, insects do not develop and do not reproduce, all physiological processes decrease, as well as the level of metabolism, morphogenetic processes are suspended.
Mosquito bite and how to protect yourself from it
To find a potential victim, a female mosquito uses several methods of orientation at once. It recognizes the heat emanating from the person, the carbon dioxide exhaled by him and the smell of sweat. This allows the insect to navigate with great accuracy even in the dark. In addition, it is believed that a mosquito that is crushed during a bite also releases substances that attract other insects of its kind.
they have no organs to suck. After the proboscis of a mosquito pierces the skin, blood begins to flow into it under the influence of its own pressure present in the vessels. If you do not use any medicines, itching and redness of the skin may appear for more than a day. In addition, in some cases, substances contained in mosquito saliva cause severe allergic reactions that require medical attention.
Why mosquitoes are dangerous
Many people perceive mosquitoes as annoying insects that bother and interfere with sleep or rest, but do not pose a serious danger. But in fact, mosquitoes are often carriers of infectious diseases, some of these diseases are deadly. The microorganisms that cause the disease can be contained in the saliva of the mosquito, which enters the human bloodstream at the site of the bite. These can be viruses or microscopic parasitic organisms.
We suggest you familiarize yourself with: Wasp sting. How to avoid? What to do?
According to official statistics, more than a million people die annually from diseases carried by mosquitoes. It is important to understand that this problem affects not only the regions that are primarily associated with diseases such as malaria or dengue fever - Africa and South America, but also other continents. Cases of transmission of various infections by mosquitoes are also noted in Russia.
Since the proboscis of a mosquito is in direct contact with blood, this insect can theoretically be a carrier of the human immunodeficiency virus. However, modern epidemiology estimates this possibility as extremely unlikely.
To avoid the spread of diseases, to make tourist resting places more comfortable or to prevent damage caused by mosquitoes to pets, the fight against these insects should be carried out simultaneously in several directions. First of all, you need to eliminate the places that are favorable for the breeding of mosquitoes.
In everyday life, the main way to combat mosquitoes is to eliminate them or scare them away. For this, both folk and modern means are used. It is known that mosquitoes do not tolerate the smell of certain plants and chemicals, which is what people use. To protect against mosquitoes, mosquito nets, canopies and other structures are used to prevent mosquitoes from entering the room.
During the bite, the mosquito injects an anticoagulant into the victim's tissue, which slows down blood clotting. There are certain categories of people who experience allergic reactions when exposed to this substance. Multiple bites of blood-sucking insects for such persons are mortal. The result is often blood intoxication with an anticoagulant and anaphylactic shock.
Blood-sucking mosquitoes are known to transmit serious diseases. Such insects transport on the proboscis not only all kinds of infections, but also microscopic parasites. All this often leads to the development of tropical fevers, encephalitis, malaria, and hepatitis in humans. For this reason, it is important to be careful when repelling mosquitoes with special repellents or odorous agents such as eucalyptus, peppermint or geranium.
Mosquito bites are deadly for some people who experience allergy attacks due to anticoagulant exposure. Intoxication and even anaphylactic shock - such a sad outcome can be contact between a mosquito and a person. Therefore, the question "how long do mosquitoes live in an apartment" for a person is of constant relevance.
By the way, in ancient times, the Chinese used these squeaky insects as a murder weapon. In a swampy area, they tied a naked victim to some tree and left it to be devoured by mosquitoes, which flocked in hungry hordes to profit from the prey. As a result of such a terrible torture, a person died from exsanguination or anaphylactic shock.
Everyone knows that mosquitoes, of which there are more than 3000 species in nature, are the first spread of infection; on their proboscis they carry parasites over long distances. They enter the circulatory system and cause encephalitis, hepatitis, tropical and yellow fever. So joking with such small, but very dangerous individuals is not worth it, you should protect yourself from bites by all sorts of effective means.
There is a popular belief that a mosquito dies after being bitten. In fact, this opinion is erroneous. An adult mosquito is able to "eat" about 8 times in a few hours, while feeling great. That is why, when 3-4 mosquitoes flew into the room, it seems to us that a whole horde of them has gathered.
So there is no connection between a bite and a mosquito's lifespan. From another point of view, there is still this connection. When a mosquito bites into our skin, it injects poison into our bloodstream, because of which we feel first a sharp pain, and then itching. And when we see a mosquito sitting and sucking our blood, what do we do? That's right, we slam it "in place". And naturally, we shorten the length of his life.
So, we can say with confidence that an insect after a bite lives from 2 seconds to 2 months.
All over the world, you can count up to 3 thousand species of mosquitoes. About 100 of them live in our country. It is worth noting that not all varieties bite. And only females hunt for human blood, while males prefer the nectar of flowers, plant leaves and can even taste bread. Females need blood to carry and lay eggs.
The unpleasant, so annoying squeak of mosquitoes produce due to the rapid flapping of their wings: they make up to 600 flaps in just one second. With the resulting sound, males attract females for mating. A visible swarm of insects, as a rule, consists of harmless males. The life of bloodsuckers is closely related to humans, although they can also bite animals and fish.
Often, chasing some of the most annoying mosquitoes with a rolled-up newspaper, you may notice that these dipterans prefer to sit on the ceiling. This is due to the fact that the warmest air in the room accumulates there, and insects feel most comfortable in it.
We suggest that you familiarize yourself with: How long do lice live outside a person's head: can nits live in pillows, how many days do they go without people - Hair
Contrary to the firmly dominant opinion, after a bite, the bloodsucker does not die and is quite capable of attacking more than a dozen times. How long mosquitoes live after a bite - worries not only the bitten themselves, with revenge awaiting their death. This is also important in order to know how to reduce the population of these Diptera in a certain area.
The female needs blood for the reproduction of offspring. She only bites during the mating season. On other days, like males, it feeds on nectar. After drinking blood, she lays eggs in a pond of stagnant water. Accordingly, draining such ponds and marshes in areas with a warm and humid climate can significantly reduce the population size.
In addition, both the many products offered by modern industry and the old methods can be used for individual warfare against mosquitoes. Various repellents, chemicals, repellents, etc. - all of them are able to cope with bloodsuckers. But you can also apply folk recipes based on knowledge of nature.
Short description
The mosquito belongs to the class of insects, the order Diptera, the family of blood-sucking mosquitoes. This creature has been living on the planet for over 145 million years. It is active in the warm season - at the end of spring, in summer. They are distinguished by a characteristic squeak, an unpleasant bite, which is accompanied by severe pain.
In nature, there is a huge variety of mosquito species, which differ in body structure, size, lifestyle, nature of the bite and other factors. But many of them prefer to feed on human and animal blood.
To understand what a mosquito looks like, it is worth considering its main features of its appearance:
- the insect has functioning wings, with the help of which it is able to fly over long distances. The span reaches 3 cm. Top covered with scales;
- three pairs of thin long legs, claws are located at the end, with the help of which they cling to the surface;
- his body is oblong;
- the parasite has a wide chest, an abdomen consisting of 10 segments, which is supported by long legs;
- on the surface of the head there are inconspicuous antennae and proboscis, with the help of which it pierces the skin, and then the wall of the blood vessel, making a bite and sucking out blood.
The piskun mosquito has a gray or brown body color. But there are species of insects that are orange, yellow, green, red. Some members of the family have lush brushes on the wings and legs.
Insects don't fly that fast. The mosquito's flight speed is 3.2 km / h. Wingless species are sometimes found.
Life cycle
From the moment the mosquito emerges, be it a female or a male, it has two main directives of life: eating and breeding. During the first few days after freeing themselves from the larval and pupal stage, a process that usually takes about 14 days, adult mosquitoes hope to mate.
However, males have to wait almost one day to achieve full development of their reproductive organs. They spend this huge time eating nectar, unlike their fellow tribesmen.
They don't use websites or bars to meet, male mosquitoes use a different method to find a mate.
To mate, they listen to the wing oscillation frequency, which is usually between 250 and 500 beats per minute.
Gender differences
Once the mosquitoes mate and the females are fertilized, the mosquito's life cycle is perpetuated. After mating, the male lives for three to five days unless killed or eaten. Females mate only once in their lives. They live much longer than the opposite sex.
The largest mosquito is found in China.
The lifespan of a female mosquito is highly dependent on the level of heat and moisture in the environment. She can live for a month or two in ideal conditions. All this time will lay eggs at night every three days.
They don't travel a lot. As a rule, no more than one and a half kilometers from the hatching site. The female produces up to 500 eggs before finally dying.
However, this entire life cycle is extremely dependent on the temperature of the water (the ideal water temperature for larvae is in the range of 23 to 26 degrees). The mosquito goes through each stage of its life very quickly, about four to fourteen days, under the right conditions.
Most mosquito species lay offspring in batches of 50 to 100, which float together on the surface of the water like a raft. They do this on water that collects in pits, ditches, even your dog's water cup.
However, some species lay them on moist, often flooded soil, awaiting the next rise in water. They can survive in winter, before spring or summer rains.
Insect eggs left on wet soil last a year until the ground is flooded again.
Where does the mosquito come from? Before becoming a mature, adult, an insect goes through several successive stages of development. To begin with, a female mosquito lays eggs in a humid environment. Most often, stagnant water is preferred. Soon, larvae form here. At this time, a young individual of a mosquito cannot be distinguished from a miniature reddish worm. The latter feeds on microorganisms that are contained in the water.
In a week, the mosquito larva transforms into a pupa, which grows special tubes for breathing atmospheric oxygen. In this state, the individual remains until it has wings. This takes several days. Having become a full-fledged dipteran mosquito, the insect goes free flight and immediately begins an active search for food.
About how and how long mosquitoes live, what conditions are most favorable for them, few people know. Their life begins with hatching from an egg laid by a female in some stagnant water. The first stage of the life cycle takes place in this reservoir. Being a larva (very similar to a small worm), the future mosquito passes through itself up to a liter of water per day.
We suggest that you familiarize yourself with: How to relieve itching from a mosquito bite in a child or adult
The next stage of development is the transformation of the larva into a pupa and the hatching from it of an adult capable of flight. Actually, this is how these little "vampires" appear. The lifespan of a mosquito depends on temperature, gender, and food abundance. It can vary from two weeks to several months.
Duration of existence in a house or apartment
Diptera insects are able to adapt to different conditions, although life expectancy is highest at optimal temperatures and humidity. The life span of a mosquito in a room (in brackets - values for a male):
- from +23 ° C - up to 43 days (up to 22);
- + 20 ... 23 ° C - up to 58 (29);
- + 15 ... 20 ° C - up to 114 (57);
- + 10 ... 15 ° C - up to 120 (60).
After copulation, the male lives no more than 5 days, and the female - up to 2 months, depending on how many degrees are in the apartment.If we proceed from the fact that indoors most often it is + 20 ... 25 ° C, females live 45-60 days, and males - 20-30.
In favorable conditions, the female will regularly fertilize and lay more and more new portions of eggs. Thus, there will always be a lot of mosquitoes in the house or apartment if you do not fight them. But this is true only on the condition that the room is residential, since the insect needs fresh blood to masonry. How long a mosquito lives in a house depends on the quality of food. If there is no access to blood, the female will die, having made 1-2 clutches, as her body will be depleted.
Mosquitoes feel especially at ease in dark and damp places. If the house has a bathroom, storage room or other suitable space, the masonry will be located there.
To reduce the number of itchy bloodsuckers indoors, you can use mosquito nets. In practice, they do not always give a pronounced effect, because dipterans enter the house not only through the window. They easily come through the door when people come in and out. You can fight both by store means and by folk methods. Some people think that mosquitoes are repelled by such grasses:
- basil;
- eucalyptus;
- tea tree;
- cedar;
- anise;
- geranium;
- lilac;
- lemon grass;
- marigold;
- elder.
If a mosquito survives into winter under natural conditions, it goes into diapause - a condition in which metabolism slows down. Indoors, the duration of the activity of the female is up to 1 year, since after the bite she does not die, but continues to mate and make clutches.
How long do mosquitoes live?
Convinced from the above, and from my own experience that the mosquito is ubiquitous, annoying and dangerous, I want to know exactly how long it will live. How long do mosquitoes live without blood? It depends on several factors:
- habitat;
- regularity of food;
- ambient temperature is the main survival condition.
At 25 ° C, a female mosquito will live up to 43 days, at 20 ° C, the period will increase to 58 days, 15 ° C - and the female's lifespan will be 114 days, 10 ° C - 119 days.
Males live in half. All this under the condition of a carefree existence, without the intervention of extraneous factors: death by the hand of a person, a cold summer, or a delicious dinner for a toad.
The annoying squeak of little pests spoils the pleasure of the long-awaited summer. The situation becomes especially unbearable in rural areas or just near woodlands. It becomes interesting: how long does the parasite live? The exact answer does not exist, because the life span of a pest depends on a number of factors.
- The sex of the insect. First of all, it is worth learning a simple fact: males live exactly half as much as females.
- Temperature. It is worth talking about this in more detail, because this information can help in confronting the squeaky enemy. So, the higher the air temperature, the less the insect will live. At a temperature of about 20 °, the female will live for about 42 days, and with a decrease to 10 °, the life span will increase to 115 days. In the case of a male, divide the number by two.
- Food. The parasite is afraid of both hunger and oversaturation. It is a myth that a mosquito dies immediately after being bitten by a person. One mosquito can bite a person up to 8 times in a couple of hours. By the way, only females feed on blood, males - exclusively on nectars.
According to scientists, the life span of such an insect is primarily influenced by temperature conditions.
The cooler mosquito habitats are, the longer they last. For example, at an air temperature of 25 degrees, a female can live a little over 40 days. With a cooling of the surrounding space to -10 degrees, this period increases to 115 days.
However, the male and female mosquitoes have different lifespans. Males, on average, die twice as fast. Why this is happening, the researchers have not yet been able to determine.However, if the mosquito has enough nutrients to survive, its lifespan is significantly increased.
Origin of the species and description
Photo: Mosquito centipede
Long-legged mosquitoes are known to mankind from chalk and tertiary amber deposits. The oldest evidence is Lebanese amber (Lower Cretaceous, about 130 million years old), the youngest specimen is found in Dominican amber, where it was found from the Miocene (Neogene period) from 15 to 40 million years. Representatives of more than 30 genera have been found in Baltic amber, some of which still exist.
Video: Mosquito centipede
Interesting fact: Tipulidae is one of the largest groups of mosquitoes, including more than 526 genera and subgenera. Most of the centipede mosquitoes have been described by entomologist Charles Alexander, a mosquito specialist, in over 1,000 scientific publications.
The phylogenetic position of the Tipulidae mosquito remains unclear. The classical view is that they are an early branch of Diptera - possibly with winter mosquitoes (Trichoceridae), a related group of all other Diptera - yielding to modern species. Taking into account the data of molecular studies, it is possible to compare the derived characters of the larvae, similar to those of the "higher" dipterans.
Pediciidae and Tipulidae are related groups, the limoniids are paraphyletic clades, and the Cylindrotominae seem to be a relict group, represented much better in the Tertiary. The Tipulidae mosquitoes may have originated from ancestors in the Upper Jurassic. The oldest specimens of long-legged mosquitoes were found in the Upper Jurassic limestones. In addition, representatives of the family were found in the Cretaceous of Brazil and Spain, and later in the Khabarovsk Territory. Also, the remains of insect species can be found in the Eocene limestones located near Verona.
Mosquitoes can survive
Low temperatures are not terrible for mosquitoes, because the latter are able to adapt well to their environment. Falling into suspended animation in winter, they are in a state of sleep until favorable conditions occur. That is, these insects are not going to die prematurely on their own, only external factors can shorten their life span.
Even their eggs are able to survive under a layer of snow. By the way, one of the varieties of mosquitoes living in the Himalayas is able to remain active even at 16 degrees below zero. Their main habitat is the tunnels and cracks in the body of the glacier. Therefore, it is rather difficult to determine how long mosquitoes live; the average life expectancy under favorable conditions for them is about 3 months.
What affects the lifespan of mosquitoes?
Although the life of a mosquito is short, it brings a lot of physical inconvenience to humans. How long does a mosquito live? What factors affect a mosquito's lifespan?
- The life span of a mosquito is directly dependent on air temperature. The cooler it is outside or in the house, the more tenacious the insect is. If the temperature is above 25 degrees, the mosquito lives less, if it is lower, it lives longer.
- Frequent feeding prolongs the life of the mosquito. Males must constantly be fed with flower nectar, and females - with blood. It has been noticed that mosquitoes have a shorter life in the forest. After all, females do not always manage to find tasty blood there.
- Natural disasters also shorten their life. Winds, hurricanes, abrupt climate changes, heat and drought, multi-day heavy rains halve the presence of mosquitoes on the ground.
- Males, according to scientists, live less than females. This is a fact that is difficult to prove. We can say a natural phenomenon.
Interesting Facts
To learn about these tiny "vampires" the following will be interesting:
- Mosquitoes are among the oldest insects that have ever inhabited the planet.Flying bloodsuckers have existed since the era of the dinosaurs.
- Mosquitoes have six paired legs. Each of them contains a suction cup, which provides the insect with the ability to hold on any planes.
- The largest mosquito in the world is the centipede. The presented insect can grow up to 6 cm or more. Unlike the well-known bloodsuckers, centipedes reproduce in wooded areas, leaving clutches in wet moss, from where the mosquito comes from.
- There is a unique variety of so-called "winter" mosquitoes. Representatives of the species are capable of being active exclusively at low ambient temperatures - about -5 degrees. In the event of warming, these mosquitoes die.
- Within a second, these insects make up to 500 movements of their wings. The result is the appearance of a characteristic squeak, by which we are familiar with such bloodsuckers.
- It is believed that female mosquitoes are more attracted to people who drank alcohol. This is probably due to the fact that alcohol causes an increase in body temperature, provokes the active release of carbon dioxide from the tissues.
- A mosquito can drink about 5 mg of blood at a time.
Can mosquitoes bring a person to death?
Given the lack of a sense of proportion with respect to blood in mosquitoes and the size of their population, it is a logical question whether mosquitoes will be able to suck all the blood. Scientists have seriously asked this question and compared some numbers. There is no clearly defined blood volume in the human body. This value can change both up and down.
As a basis, it was assumed that an adult of average build has about 5 liters of biological fluid. Calculations were made based on the fact that about 75 ml of blood falls on 1 kg of human body weight.
Mosquito bite
It is not possible to accurately calculate how many mosquitoes are needed to drink all the blood from a person, so theoretical data are taken as a basis. If the average bloodsucker drinks only 5 mg of blood at a time, then to kill a person it will take at least 1000 individuals, provided that each one completely fills its belly. It is difficult to face such a situation in real life.
A weak immune system can also bring death closer. It will give a vivid allergic reaction to anticoagulants injected by bloodsuckers, and will provoke edema, suffocation.
Also, in order to bring the human body to complete exsanguination, it is necessary to exclude any drinking and food. In ordinary life, this is not possible.
Thus, the answer to the question of whether mosquitoes can bite to death has only a conjectural answer based on generally accepted facts. But even one mosquito bite will be enough to bring a dangerous disease into the body. And it can already become the cause of death.
