Mosquito larva. Distinctive features, life cycle and stages of development. What is the name and what does the mosquito larva eat What does the mosquito larva eat in fresh water

The mosquito larva is the second stage of insect development after the egg. This is an important period in the life of a bloodsucker, because there is an accumulation of nutrients for adults. Despite their small size, they play an important role in nature.

Appearance of the larva and structure

Answering the question of what a mosquito larva looks like, one can describe a small worm, the body length of which usually does not exceed 1 cm. there are 2 black eyes.

The color of the larvae depends on. In the well-known squeaker, they are brown, and in the malarial, they are green.

At the end of the body of the larva there is a long process, obliquely located in relation to the abdomen. This is a breathing tube, at the end of which there are 2 tiny holes: vital oxygen enters the body through them.

If you approach the reservoir where the mosquito larvae live, and sharply move your hand above the surface of the water, then they will abruptly break away and rush deep into to hide from potential danger. To do this, they are helped by the so-called swimming hairs. They are collected in bundles and attached to the body of the worm. The largest of them is located on the tail segment, playing the role of a kind of motor and rudder, setting the pace for swimming and the direction of movement in the water.

The entire life of a mosquito in the larval stage lasts an average of 3-4 weeks. Its exact duration depends not only on the species, but also on the conditions. environment primarily water temperature. During this time, intermediate molts occur: the insect sheds the body cover - the exoskeleton, so that it can increase in size.

Mosquito larvae are characterized by intensive growth: when they first hatch from the egg, their length does not exceed only 1 mm and they are almost invisible to the naked eye. By the end of the stage, the body is stretched up to 1 cm. The body weight increases even faster: according to biologists, its difference from the original can be up to 500 times. When the development of the larva ends, it transforms into a pupa with a more complex structure.

How is her life going?

In all species of mosquitoes, of which there are about 3,500, the larvae live in the water, where the female lays her eggs. For the birth of offspring, she can choose:

• fresh water, most often calm and with stagnant water; small size and depth up to 1.5 m;
• sewers;
• puddles that do not dry out for a long time;
• pits filled with water;
• barrels and tubs.

The structure of the larvae different types may differ significantly, and this determines the features of their behavior. But for the majority, due to the presence of a breathing tube on the tail, there is a need to be in a position upside down near the surface of the water. So they expose holes for oxygen. Only an approaching danger can force them to go deep into their native reservoir, however, after a maximum of 15 minutes, the worms will again hang at the surface. But there are also mosquito larvae living at the bottom of reservoirs - for example, a ringing mosquito.

The life of the larva is also interesting. She, unlike her brothers, does not have a breathing tube at the end of her belly, but there are holes located along the edge of her body.

The necessary conditions

Varieties of mosquitoes are very different from each other: some prefer the hot and humid climate of the tropics, while others feel good near the Arctic Circle. Some for the development of their larvae choose water bodies that are well warmed up by the direct rays of the sun, while the rest are looking for shady ponds. In general, scientists call the range of 10–35 °C the acceptable temperature for development, but the optimum ranges from 25 to 30 °C: in such conditions, growth is faster.

What danger awaits the larvae?

Observations have shown that most of the larvae die, and only some of them manage to turn into a pupa. The cause of death can be bad weather conditions (for example, low water temperatures or natural disasters). But such losses are more than compensated by the high fecundity of these blood-sucking insects, so there is no need to talk about a decrease in their population.

Often these small worms are eaten: mosquito larvae are the main food for other inhabitants of the reservoir: fish and amphibians. In front of these enemies, they are not protected in any way.

Another threat lies in the unfavorable ecological situation. If the reservoir is contaminated with oil products, then a thin film forms on the surface of the water. It blocks the larvae's access to air, without which they die after 15 minutes, and also clogs the holes in the breathing tube.

Nutrition

With what ? Their diet includes microscopic organisms such as unicellular algae, as well as organic plant debris that decomposes in the water. To find suitable food, the larva filters the water. On average, its volume in 24 hours is 1 liter, which is an impressive figure for such a small creature.

bloodworm

Motyl - as the larva of a mosquito from the Chironomidae family (they are also called twitchers and bells) and Tendipedidae is called - perhaps the most significant in human life. These creatures are used as bait in fishing, with which you can get a rich catch, so they are actively sold in specialized stores. The bell mosquito larva is well known in the aquarium trade and among people who keep exotic reptiles at home: it is the right food for their pets.

Bloodworms are sold fresh and frozen. Individuals are sorted by size depending on the size of the fish for which the bait is intended.

These larvae prefer to live at the bottom of reservoirs densely overgrown with vegetation. They are benthic organisms - spending their lives in silt. This is where they find their food. But, like all species, they need oxygen, so they periodically float to the surface.

The bloodworm is a larva of the Polypedilum vanderplanki mosquito with an enviable survival rate. Scientists conducted an original experiment in collaboration with the space organization, when these creatures were carried out in outer space (being outside the ISS) longer than a year. After returning, 80% of the larvae were alive. Therefore, bloodworms are rightfully called the most complex organism, known to science, which survives drying.

Bloodworms are characterized by a red color, which they acquire due to the content of hemoglobin. Their way of life is also curious: with the help of a substance secreted by the salivary glands, they glue a kind of house in the form of a tube out of silt. It serves as a shelter for them, so the larva sticks out of it only the front part, which finds food.

The life and development of mosquito larvae is quite interesting. They are beneficial, performing the function of a living water filter and being fish food, which is actively used by humans. Also, the larvae play the role of an indicator of the purity of water bodies: if it is polluted, then their population dies.

The mosquito goes through three more developmental stages before becoming a pesky adult insect. The larva (in Latin larva) is the second of them, after the egg and before the pupa. Almost everyone who has ever approached stagnant water in summer has an idea of ​​what a mosquito larva looks like: deep puddles, lakes, backwaters, ponds. It is worth touching the surface, and a flock of worms flees to the depths, folding their bodies into figure eights.

The appearance of the larva and the structure of its body

Larva (larva) looks like a thin worm, about 1 cm long. If you carefully examine it, you can see with the naked eye a thickened thoracic region, consisting of approximately identical segments of the abdomen, head with a pair of black eyes and a breathing tube. Its deviation from the axis of the body is striking, making the tail look like a forked fin. The tube has two holes through which the future mosquito receives oxygen.

A small increase allows you to see the tufts of swimming hairs located throughout the body. Particularly long tufts are located on the thoracic segment and tail, providing a high speed of movement in the water and the ability to change direction. The characteristic "eight" swimming allows you to quickly sink to the depth and rise to the surface, as soon as the threat has passed.

The conditions for the development of mosquito larvae affect the duration of the period, which ranges from three to five weeks for different species, and the frequency of molting. A newborn larva, having hatched from an egg, has a length of no more than a millimeter, by the time the larval stage ends, the dimensions can be 11 millimeters, and the mass increases by 500 times! The exoskeleton is not capable of growth, so the future insect molts four times.

Mosquito larva: how is her life going?

The female mosquito chooses a reservoir for laying eggs according to a variety of parameters. Required:

• fresh water with a minimum of suspended particles;
• the presence of bioplankton in the water - the main food of the mosquito larva;
• lack of strong currents and whirlpools;
• depth from 1 to 1.5 meters, which guarantees warming of the water to the very bottom and reduces the risk of drying out.

Marshes, deep puddles or water holes, sewers, backwaters and shallow lakes, as well as garden barrels and rainwater tanks, usually become a home for the larvae. Most of the time, mosquito kids spend upside down at the very surface of the water, putting a breathing tube on the surface. With rare exceptions, such as a ringing mosquito living at the bottom of a reservoir, the larvae can go to a depth of a maximum of a quarter of an hour.

What do mosquito larvae eat? Unicellular algae and protozoa microorganisms, as well as decay products of plant organic matter. The larva receives food by filtering water, and per day passes a liter of liquid through itself - a solid volume for a creature of this size.

Bloodworm - a larva that goes fishing

A small percentage of larvae will be able to live four weeks of the larval stage and become a pupa. They die from temperature changes and drying up of water bodies, some become food for fish and amphibians, some will be caught for later use in fishing and in home aquariums. Turning into fish food (bloodworm) is the fate of a significant number of insects at the larval or pupal stage.

Bloodworms - worm-like larvae of the twitching mosquito and the ringing mosquito (lat. Tendipedidae and Chironomidae), remain the most popular bait for catching fish, as well as an excellent food for most aquarium fish, which does not benefit the population of mosquitoes of these families. However, other families have their own characteristics. The survival rate of mosquito larvae in wild nature and near civilization is almost the same.

The life cycle of this well-known insect originates in water (from a puddle to a lake), most of all in time having the form of a mosquito larva. Forest representatives of these insects lay their eggs in places where water accumulates, such as hollow trees. After a little time (from 2 to 5 days), a mosquito larva hatches from the egg.

In appearance, the emerging larva is very similar to a small worm. Its growth and development takes place directly in the water, where there is enough food and optimum temperature. The larva changes several times before turning into a pupa. After some time, a fully mature mosquito appears.

mosquito larvae various kinds differ not only in appearance, but also in a number of other features. Depending on how the larva is located in the water, its variety can be determined. In addition, each species of these insects has its own temperature conditions for development. It can be both ponds and ditches illuminated and heated by the sun, and reservoirs located in the shade. To fully develop, mosquito larvae need a temperature of 10 to 35 °C.

This species is also known as the pisk mosquito. It can be found everywhere. Pisk mosquito - blood-sucking insect, although only females are such. For them, this is a natural process necessary for breeding offspring. Males feed exclusively on plant juices. This species is also known as a carrier of dangerous diseases (infections, meningitis, etc.).

Peeper mosquito larvae are born in such water bodies as sewers, stagnant water of basements and cellars, treatment pits, etc. They develop well even in deep darkness and under high temperature conditions.

For breathing, this species uses a siphon located on the eighth segment of the abdomen. If the larva is under water, it closes with a special valve. For movement, the larva of the Pisk mosquito uses the caudal fin, which is located on the last (ninth) segment of the abdomen and consists of the smallest bristles.

Malaria mosquito larvae

This type of mosquito is considered the most dangerous, as it is able to endure very difficult conditions in treatment. diseases. This species lays its eggs in clear waters with moderate vegetation. They are well suited to places with a low degree of alkalinity and water bodies where filamentous algae grow - they serve as a refuge, and often food for larvae during the entire development period.

The larva of the malarial mosquito hangs at the very surface of the water in a horizontal position, since this species does not have a pronounced breathing tube at the tail end. Peculiar breathing holes are located in them almost at the very end of the abdomen. The entire surface of the body of the malarial mosquito larva is covered with bristles that grow with it and gradually change color from black to green or reddish. The food for the larvae are small organisms that live in the water. They catch them with their mouth brushes and direct them into the mouth opening.

Stinging mosquito larvae

Mosquito larvae of this species differ from others in the presence of hair tufts on the siphon, located at its very base. Adults have spiracular bristles, dark spots located on the wings and white rings on the legs. This species lives in areas close to the forest zone.

The place of birth and development of the larvae of the stinging mosquito is water bodies, small in volume and size, which are formed temporarily after heavy rains both in the city and in the countryside.

Swamp mosquito larvae

This species is also known as the meadow. It is not a blood-sucking species, feeding on exclusively food plant origin(nectar). They cannot be found in cities, as swamp mosquitoes live in meadows flooded with water, in a forest zone where there is a lot of moss, or in other damp places near water. By external signs, they are similar to the centipede mosquito, differing from them in the venation of the wings. They can be seen most often at dusk, slowly flying in the air.

The female meadow mosquito lays its eggs directly in water, in damp soil or in damp moss. Being in these places, the hatched larva feeds on the remains of decomposed algae and plants. Some, however, are able to manifest themselves as predators. They build silk tubes, breathe air, for which they often pierce the roots of aquatic plants to obtain oxygen.

Mosquito centipede larvae

This large species of grayish mosquito is not a bloodsucker. Their food is dew and plant nectar. This species has neither a stinger nor a piercing proboscis. The habitat of the centipede mosquito is an area with a high level of humidity: thickets near shallow water bodies, swamps and thickets of forests near the lake.

The female weevil mosquito lays elongated eggs by hopping above the ground and poking its abdomen into the soil. The hatched larvae grow and develop in plant roots, rotting tree bark, or on the surface of silt. Appearance they resemble worms with a large head, in which an asterisk is at the end of the body - this is a well-developed oral gnawing apparatus.

Mosquito larvae of this species cause great harm to humans when they destroy crops. Their favorite food, apart from algae, is young crop seedlings with soft, succulent roots.

This small mosquito, the most numerous in appearance, is distributed on all continents except snowy Antarctica. It lives in shady forest areas and in the tundra. Activity begins in mid-April and continues until severe cold. This happens because female biting mosquitoes lay their eggs in late autumn, and with the first warm days, countless larvae can be seen in the puddles. To start development, they need a temperature just above 5 ° C. This type of mosquito is very dangerous, as it is a carrier of serious diseases, such as the Zika virus and yellow fever.

The characteristic features of the biter mosquito are clearly visible stripes of white on the limbs and on the body. Female biters feed on blood, after which they lay eggs. To do this, they do not have to be satisfied at all, a small amount is enough to give offspring. That is why this species is so numerous.

The laid eggs have a yellowish tint, but during the day they darken, turn brown. The hatched larvae of the biting mosquito grow and develop in the aquatic environment. They hang upside down in the water. They breathe oxygen, so they cannot be at depth all the time. They feed on dead tissue particles, microorganisms and algae. The larva becomes a chrysalis and rises to the water surface, where it lives for about 2 days before the mosquito appears.

Mosquitoes need water to grow. The female lays her eggs in it. A suitable place for this can be not only a pond or lake, but also a ditch, puddle, barrel or other non-drying container. In the forest, females look for suitable places in hollow trees or other natural depressions where water collects. Soon a mosquito larva hatches from the egg.

Mosquito life cycle

Before being born, offspring go through several stages of development. One clutch of eggs can reach several hundred pieces. The hatched mosquito larva looks like a small worm. It grows rapidly if it is fed enough and the environmental conditions are suitable for its development. During this time, there are several links. At the last change of the shell, the larvae turn into pupae. Outwardly, they differ in the presence of a "belly". Despite the seeming clumsiness, the chrysalis is more mobile and can move faster in the water column.

When the time comes, its shell at the top bursts, a fully formed mosquito emerges from the gap. The exit process takes place at the surface of the water. Young mosquitoes easily move to land, where they seek refuge among vegetation and wait for the moment to begin adulthood.

Body structure and development

The larvae of different species of mosquitoes differ in appearance, but they can also be identified by other characteristic features. Some have adapted to breathe atmospheric air. On the body they have breathing tubes that they expose above the water. For such a life, they occupy a vertical position and only in case of danger hide in the depths.

In order to be able to receive a portion of oxygen, the larva must take one position or another in relation to the plane of the water. According to the location method, the species affiliation is determined. In this way, the larvae of the malaria mosquito can be easily identified. It hangs near the surface horizontally. The larva of the twitching mosquito breathes oxygen dissolved in water. She absorbs it all over her body.

During development, the body increases in size, the internal structure of the body becomes more complicated. When hatching from an egg, the size of the larva is about 1 mm. At the transition to the pupal stage, they reach a size of 8-10 mm. The dimensions increase up to ten times, and the volume up to 500 times.

There are four stages of growing up. On each of them there is an intermediate molt. The mosquito larva sheds its exoskeleton to be able to get bigger. At the last stage, it turns into a chrysalis with a more complex organization. internal organs and systems.

Habitat

Different types of mosquitoes have their own temperature regimes of development. Some like well-lit and sun-warmed ponds, while others prefer to stay in the shade. Temperature regimes in different climatic zones differ markedly. It is believed that larvae can develop between 10 and 35 °C.

The optimum temperature is 25-30°C. Mosquitoes use large reservoirs for laying eggs less frequently. In such conditions, there are many enemies for the larvae. Almost all types of fish are happy to eat them at different stages of development.

Mosquito larvae die in oil-contaminated water. A thin oily film on the surface prevents them from breathing. However, some species survive in such conditions, having adapted to breathe oxygen dissolved in water.

Peculiarities

The larva of the malarial mosquito does not have a pronounced respiratory tube at the tail end. On one of the segments of the body, she has holes. To touch them to the surface of the water and get a portion of oxygen, the larva takes a horizontal position. These peculiar spiracles are located on the penultimate segment of the abdomen.

Red mosquito larva. It's the hemoglobin dissolved in her body that gives it that shade. This feature makes it possible to maintain a supply of oxygen in the body. This allows you to stay for a long time in your shelter, buried in the silt at the bottom of the reservoir.

To feed themselves, the larva, on average, filters up to a liter of water per day. She filters it, looking for particles with nutrients. Microorganisms caught at the same time also serve as food for them.

bloodworm

Ringing mosquitoes (twitchers) differ from their relatives by the absence of a proboscis. They don't bite. Their oral apparatus is not developed. There are differences in the stage of development of the larva. She adapted to life in the silt.

The bell mosquito larva has a red color, a dark head and is well known to fishermen as a bloodworm. This living creature loves not only the fish of natural reservoirs, but also the aquarium. There is a large one and a smaller one. Size does not depend on environmental conditions and good nutrition. These are the larvae of different subspecies of ringing mosquitoes.

Bloodworm equips narrow passages-tubes at the bottom of the reservoir. It builds them from particles of silt, sticking them together with the secretions of its salivary glands. There are species that make moves in the leaves and stems of underwater plants, boring into them suitable depths. At rest, the larvae protrude from their shelter and actively feed. Their diet includes both plant plankton and small aquatic animals: daphnia, rotifers, cyclops. In times of danger, the bloodworm hides in its shelter.

Unlike other mosquito larvae, this species has adapted to live even in low oxygen environments. It does not rise to the surface of the water to breathe. Even turning into a chrysalis, the bloodworm floats up only to turn into an adult mosquito.

Summer is coming soon, which means that every person will meet with insects that he has long "loved" - mosquitoes. They get us from the very early childhood and do not give rest even in old age. A kind of myths have even appeared in humans about these bloodsuckers (for example, that mosquitoes can “recognize” the composition of human blood and therefore bite mainly those who have “young” blood), but how much do we know about them?

Mosquito as a biological species

The mosquito is distinguished from other insects primarily by its oblong (up to 15 mm) and at the same time thin body. Disproportionately long legs (there are six of them), which end in two claws, support a wide chest and an abdomen divided into 10 segments. Narrow wings reach as much as 3 cm in span. These insects are dominated by brown, yellow and gray colors in color, but you can meet others, for example, green, red. Mosquitoes have a very light long body

The receptors and organs of smell of the mosquito are located on long antennae, which are divided into 15 parts. With the help of these "sensors" mosquitoes track down their "prey", and the nutrition of males differs from the diet of females.

This is due to the fact that females lay eggs, from which mosquito larvae subsequently appear; for the full development of the "fetus" it is necessary a large number of protein food, which is blood - a person or an animal. The male does not need protein, he has enough flower nectar or plant juice. In this regard, the oral apparatus of males is underdeveloped, it cannot “gnaw through” the skin and drink blood.

Mosquitoes do not know how to squeak, as is commonly believed. A peculiar sound occurs during the flight of an insect, when the frequency of movement of the wings is approximately a thousand times per second.

The mosquito has very powerful jaws.

Life cycle

There are four stages in the life cycle of a mosquito. First, the female lays 30–150 eggs in the water; this happens every 2-3 days. The emerging larva lives in a reservoir and feeds on various microorganisms. They have special breathing tubes for breathing. During this stage, the larva molts four times, then turns into a pupa, in which it develops over the next five days. In the cocoon, the larva gradually changes its color, acquiring the color familiar to its species. When the pupa opens, the insect is already mature; this stage is called imago. Mosquitoes live on average up to 3 weeks.

Mosquito larvae live in water

Mosquitoes live advantageously near water bodies, which they need to breed offspring. But they settle in any humid hot places, including apartments.

Mosquitoes can be found in every corner of the globe, with the exception of the south and north poles and the cold territories adjacent to them.

In the city, the male and female mate, after which the female obtains protein food and then lays eggs. Outside the city, males gather in a large swarm and wait for females there, after which mating occurs, and the female goes in search of a "protein donor". After the eggs are laid, the breeding cycle is repeated.
Mosquitoes mate quite often (after laying eggs, the female is ready for new offspring)

The role of mosquitoes in the biological chain

Every organism is part of a biological chain; and creatures like mosquitoes are no exception. They feed on other insects, animals and birds: frogs, newts, salamanders, dragonflies, spiders, the bats, chameleons, water bugs, lizards, swifts and hedgehogs.

Mosquitoes have a very light body, so they don't cause the web to sway when they hit it. Spiders only become aware of their prey when they crawl out of their hiding place.

Since mosquito larvae develop in water, they become food for the inhabitants of reservoirs: fish, swimming beetles, crustaceans, water striders.
Mosquito larvae must be included in the diet of mosquito

Types of mosquitoes

There are about three thousand different species of mosquitoes in the world, among which there are those that carry deadly diseases (for example, malaria).

Common mosquito (peeper)

Piskun is very annoying

This type of bloodsucking insect is found everywhere and is particularly importunate. Adult individuals reach a length of only 8 mm, but at the same time, quite calmly for themselves, they can tolerate quite serious diseases (meningitis, infectious eczema, and others).

Long-legged

Weevils feed only on plant sap.

Long-legs live in areas with high humidity and a lot of vegetation: in swamps, reservoirs, in forest thickets near the lake. This is a large species (the body length of an adult reaches 8 cm in length), which is why it is often confused with dangerous to humans. The centipede feeds exclusively on plant sap, it is safe for both humans and animals. True, agricultural land and forest plantings suffer greatly from it.

The larvae of the centipede are very voracious, eating everything tasty from plant foods both in water and on land.

pachyderm

These mosquitoes can be called clean, because they not only do not bite a person, but do not even carry any infections on their paws, as flies do. It is believed that the meeting of a mosquito and an allergic person will not cause any reaction in a person.

My friends, who are allergic to literally everything that can be, calmly endure clouds of these mosquitoes in the warm season.
Tolstopodka is very similar to a fly or an ant uterus

This type of mosquito looks very similar to the queen ant; small birds (for example, sparrows) like to feast on them. For nature, pachyderms are very important, because they produce humus well.

Friends said that they saw these “flies” many times in greenhouses, and they found them by flying sparrows. Such an invasion of insects and birds continued for several days, after which the mosquitoes disappeared.

An adult very strongly resembles a moth of a faded gray-brown color. What distinguishes them from beautiful butterflies is that they have villi on their wings, not scales. The caddisfly can be called a lover of cleanliness, since it lives near those streams, ponds, lakes and swamps, where it is clean. If the reservoir is littered (by a person or simply heavily overgrown), they cannot be found there.
Caddisflies live only near clean water bodies.

If you catch a caddisfly, you can feel bad smell, which, most likely, the insect is protected from birds.

hallmark of these insects is that during their adult life (1–2 weeks) they do not feed on anything, therefore they are absolutely harmless to humans.

Taiga

The monument to the taiga mosquito stands in the city of Noyabrsk (Yamalo-Nenets District)

The taiga mosquito differs from its relatives in the pain after a bite. The Nenets say that cold and frost are much easier to bear than the consequences of the "hunt" of these insects in the warm season.

The taiga mosquito has a very long trunk, which is slightly more than half the length of the body, and quite powerful paws.

Mosquito-twitch (or bell)

Twitchers are very beautiful and absolutely safe for people.

Another harmless mosquito whose lifespan is only 2-5 days. It lives in thickets of reeds, on the banks of rivers and swamps. A distinctive feature is the yellow-green color and very long limbs. The antennae on the head are covered with fairly long villi. Twitchers feed exclusively on plants, therefore they do not cause any inconvenience to humans and animals, even when they fly in whole swarms nearby.

Culex is a large genus of mosquitoes

Culex is a large genus of insects with over 1200 species. Adult individuals reach a length of 10 mm, differ in the characteristic shape of the oral apparatus - a case. Сulex are carriers of dangerous diseases (filariasis, encephalitis, malaria and others).

Malaria mosquito carries deadly disease

This mosquito got its name because of the causative agent of a dangerous disease carried by it - the malarial Plasmodium. It is quite difficult to distinguish such a dangerous insect from an ordinary one, but knowledgeable people are guided by the following structural features:

• the hind limbs of the malarial mosquito are longer than those of the common mosquito;
• antennae the same length as the sting;

Mosquito bite - what is the danger

The female bloodsucking mosquito has sharp jaws, with which it gnaws a hole in the skin of a person or animal, while spraying saliva with a substance that prevents blood clotting into the body of the victim. It is this component of saliva that causes allergic reaction in the form of itching, redness of the skin and swelling. Then she plunges her proboscis into the wound and sucks out the "red liquid".

The female may bite several times until she receives the amount of blood and protein she needs, after which she goes in search of a moist place where she can lay her eggs. Unfortunately, mosquitoes do not die like bees, but, on the contrary, multiply after being bitten.
The female is ready for fertilization immediately after she lays her eggs.

Mosquitoes are not very picky and bite everyone: sick and healthy, so an infection from one organism through the proboscis of an insect can be transmitted to another organism and infect it. True, there is one important condition for infection - the causative agent of the disease must develop in the body of the bloodsucker, and not just get there. The following diseases are predominantly transmitted:

• malaria;
• yellow fever;
• encephalitis;
• meningitis;
• Lyme disease;
• filariasis;

Fortunately, HIV and AIDS are not transmitted through the bite of this insect.

In Russia, mosquitoes extremely transmit infectious diseases from one person or animal to another, but the “special component” of their saliva can cause an allergic reaction, which can turn into a dangerous angioedema (if not stopped in time).

I heard several times that people died after numerous mosquito bites because they were not provided with medical assistance in time.

Video: what is the danger of a mosquito bite

There is no need to be afraid of the warm season because of some unpleasant insects: you already know what these or those mosquitoes look like, which ones are really dangerous for humans, what consequences their bite can lead to, and you can, having studied a little more literature , provide first aid if necessary. No bloodsuckers should spoil either you or your loved ones a well-deserved rest.
