Summer is a long-awaited time for rest and vacations. The summer season is also characterized by frequent occurrences of midges, bugs, spiders, flies and many other insects. This is one of the negative moments of summer. Wasps are no exception. The characteristic period of their activity is from July to September. The wasp sting is quite painful, there are cases when it is even dangerous.

If you were stung by a wasp?

The poison is contained in the sting and jaws of the insect. Acute pain, burning sensation is often a characteristic sensation during a bite. But not all of these insects can sting.

Only female wasps have a sting. It has a smooth structure and therefore does not remain in the skin when bitten. Accordingly, the wasp has the ability to make many bites and sting a large number of times and not die. You can't say that about a bee. She stings only once, losing the sting.

Then she dies. The wasp is a hunter. It feeds on various insects. He also does not disdain carrion (eats meat, fish, rotten food). As a result, in the summer, garbage cans and garbage cans attract a large number of these insects. Accordingly, the wasp is a carrier of all kinds of bacteria. Wasp people sting defensively. The consequences of a bite and the body's reactions are varied.
The most classic development for the affected area is redness and slight swelling. In more complex cases, allergic manifestations of various degrees occur. In any case, it is necessary to take measures that reduce the development of poison in the body.

Options for the consequences of wasp bites

People are individual and therefore everyone has their own reaction to wasp venom toxins. And therefore, reactions to a bite can be different. An important role is played by:

• the site of the wasp bite (skin, eye area, mouth, larynx);
• individual susceptibility of the human body to poison.

A wasp sting is an unpleasant event that affects everyone differently. At the initial stage of the bite, this is a sharp pain, similar to the pain of getting a burn. After a short period of time, the pain is replaced by a small swelling with redness at the site of the bite. Symptoms disappear within a short period of time after the bite. People who are allergic to wasp venom toxins have different reactions.

Range of symptoms

• unstable pulse (fast or slow);
• severe swelling of the bite site (especially the area of ​​the eyes, mouth, mouth, larynx). The tumor spreads to a large area of ​​tissue, and in some cases to organs;
• wheezing, breathing quickened, breathing hard;
• dizziness;
• loss of consciousness;
• nausea, vomiting;
• the bite site itches (itching can spread beyond the wound);

The swelling that occurs after an insect bite can tell a lot about the development of toxins in the body. If the body successfully fights the poison, then the swollen part of the damaged surface takes up a small area around the bite and dissolves after 2-3 hours. If the edema becomes large over time, this is the first sign of an allergy to a wasp sting.
Wasps often sting children. The reasons are different. This is the curiosity of children for striped insects, the frequent use of sweets that children love. Babies are much more sensitive to a wasp bite than adults. Doctors recommend that parents go to medical institutions after a wasp sting.

Especially if there are allergic reactions to a wasp sting. Remember! Timely medical attention can prevent the consequences of an insect bite and the consequences will be minor. The question of the danger of a wasp sting for pregnant women remains very important. Medical sources say that a wasp sting does not have a negative effect on the fetus that a pregnant mother is carrying. the same as for any person. But the question remains about the increased sensitivity of the pregnant woman's body to wasp stings. In such cases, the main rule is to avoid contact with insects.

First aid

If you are bitten by a wasp, leave this place. When a wasp bites, it secretes a special enzyme that summons other relatives. It is enough to brush away the insect with your hand or any other means at hand. It is not advisable to put pressure on the insect. You can't do this. This will only enhance the release of the enzyme.

Wasp bite help

It is worth being careful when providing assistance with a wasp sting. A quick reaction to a bite, correctly defined symptoms and clear actions on them will help to quickly relieve pain and swelling and, as a result, will lead to a quick recovery. Otherwise, timely medical assistance is provided.

Helping people with increased allergic reactions

Allergy sufferers, while on vacation, should always be ready to meet insects and know the consequences that their bites will bring them. Should be able to do basic methods of rendering assistance. If you are allergic to a wasp sting, be on the lookout. In the literal sense, every allergy sufferer should carry a first aid kit with a characteristic set of drugs.

The basis of such a first-aid kit should be antiallergic (antihistamines) drugs. People with asthma should have an inhaler with them. After all, its timely use excludes the occurrence of asthma attacks. Those suffering from heart disease and concomitant diseases should have drugs of the heart group with them. A tourniquet is also a must in the medicine cabinet. If a leg or arm is affected, a tourniquet will much more effectively act as a stopper for harmful toxins than a tight bandage. Allergy sufferers should clearly know the symptoms of an allergy. After a bite, you need to see a doctor urgently. After all, medical care is always of better quality than self-medication.

When should I go to the hospital?

There are times when a wasp or swarm bites two or more times. In such cases, you need to urgently contact a medical facility. There is a generally accepted opinion that after three bites (for children, two or more bites), a toxic reaction of the whole body can begin. If a wasp has bitten on the face, behind the ear, swelling of the entire face occurs. A bite in the larynx, on the lip and on the tongue is very dangerous.
The consequences are dire. The larynx swells, the tumor goes beyond the local character. This often leads to suffocation. And therefore, the reaction to this type of symptoms should be immediate. If the skin itches, itches, a rash has formed, these are also the first symptoms that you should pay attention to and contact the appropriate specialists.

classmates

Since childhood I am afraid of wasps, bees and this whole family. Mom says. they bit me in my childhood, and now I am quite an adult aunt, I run from them with a squeal. Involuntarily. And “brush off” is not mine. Although I was also told in childhood that the wasps would flock even more. I know that you can't push, but no. if there is a possibility - I crush to death, literally grind to shreds ... Once I was once bitten by a wasp, then I scratched this place for three days, everything swelled

My child reacts very painfully even to mosquito bites, everything swells up, and this summer we were bitten by a wasp, the hand was swollen and very painful, smeared with soda, panthenol helped a little, but still had to go to the doctor, so now we always carry a first-aid kit with us with antihistamines, bee stings for allergy sufferers are really very dangerous

People treat wasps with caution and dislike, expecting a sudden attack and bite. In fact, predatory insects are not so aggressive. If they are not provoked with sudden movements, then they calmly fly away on their own business. Neighborhood with wasps can benefit gardeners. One female catches 20-30 pests per day - flies, caterpillars, beetles, butterflies. Small insects serve as food for the larvae. In nature, the benefits and harms of wasps balance each other. Stinging insects are part of the food chain; if this link is removed, an ecological disaster will occur. Is the peaceful coexistence of humans and wasps possible?

Description and lifestyle

Wasps, along with their closest relatives, bees and bumblebees, belong to the order of Hymenoptera. Numerous insect species share a common body structure. Their chest and abdomen are connected by a thin stalk-like waist. Adults have two pairs of membranous wings. Large eyes are complex in structure, allowing you to see in several directions. Powerful jaws are adapted for gnawing fruit peels, removing bark from branches, tearing prey. The body is covered with many hairs. The movable antennae are the organ of smell and help to determine the size of the honeycomb during the construction of the nest.

Information. The narrow waist allows the wasps to fold in half and sting the enemy from any angle. This quality helps to cope with a large enemy.

Among the stinging insects, there are solitary and social wasps. Only a part of the species has the usual yellow-black color. For example, the chitinous shell of a lustrous wasp shimmers with a blue, purple and green metallic sheen. German females are densely covered with red hairs and have patterns on the abdomen. The size of the adult wasp is from 5 to 100 mm. Insects differ not only in size and color, but also in behavior patterns.

Adult wasps, regardless of the species, eat plant foods. They prefer to collect nectar, drink juice from soft, rotten fruits. Protein food is necessary for growing larvae and uterus. To get food, adults have to hunt. The benefits of the wasp, a polyphagous predator, in insect control.

Information. The pompilid road wasps are able to cope with the poisonous tarantula. With a quick blow, they paralyze the spider and drag it into the hole to feed the larva.

Females of solitary wasps make nests in the ground or plant stems. They leave their offspring food in the form of paralyzed insects. Public wasps live in colonies. The family is ruled by the uterus, which lays eggs. Worker wasps help care for larvae and build multi-tiered nests. In the fall, the dwelling becomes empty, only fertilized young queens survive the winter.

Striped vultures

Scolias are primitive solitary wasps that help to exterminate the larvae of lamellar beetles. The sizes of the insects are from 10 to 100 mm, the wingspan is 60-100 mm. The body color is black, bright yellow or red spots stand out on the abdomen. The membranous wings with a purple sheen. Females lay an egg on the larva of the beetle, bronze, rhinoceros beetle. Scolia does not kill the victim, but immobilizes. The larva that emerged from the egg begins to feed on the least important organs. This natural instinct keeps food fresh for a long time.

The closest relative of scolia is typhia. It is smaller in size (5-12 mm), the body is evenly colored black. The female lays eggs on the larvae of pests - bread beetles. Thick-legged typhias live in Russia. This species has a reddish-brown limb. The entire body is covered with white hairs. Females dig a passage to a depth of 10 cm in order to paralyze the June beetle and lay an egg. After a few hours, the beetle larva is able to move, but its existence will not last long.

Information. The wasp Larra acts in a similar way, only she leaves her offspring to feed on bears.

Striped paper wasps do not catch pests in the ground, but on the surface and in the air. Their favorite prey is flies. They do not avoid caterpillars, bedbugs, leaf rollers, mosquitoes, aphids.

Wasps and flowers

What else is the use of wasps? Pollination is essential for plants to produce good crops. About 20% of crops can be wind-pollinated or self-pollinated. Others need helpers to transfer pollen. Traditionally, it is believed that bees do this. But the wasps do the same. Adults eat plant foods. They love nectar, so they fly from one flower to another. Pollen clings to the legs and body, covered with hairs, and falls on other flowers. The radius of flight of bees is limited by the location of the apiary, and their striped relatives settle anywhere. Wasps play a subtle but significant role in pollination.

Why don't people like wasps?

If the benefits of striped insects are not always noticeable, then people feel the harm from them in full. It manifests itself not only in bites, but also in eaten fruits and berries.

Spoiled harvest

After pollination of plants, insects claim fruit. They prefer soft, sweet fruits. A large swarm can damage a large number of apples, pears, plums, raspberries. The grapes are especially affected. Wasps with strong mandibles easily gnaw through the skin and drink juice. Damaged berries impair the presentation of the bunches.

Various methods are used to combat insects:

• hang bait;
• destroy nests;
• treat grapes with chemicals;
• wrap the bunches in special bags.

Bee exterminators

The greatest harm from wasps is experienced by beekeepers. Predators are attracted by the aroma of sweet honey. They sneak into the hive and eat the supplies prepared by the bees. Lack of food weakens the brood. In addition, a battle ensues between bees and wasps, in which many honey plants perish. A strong family is able to fight off the invaders of paper wasps, and a weak one may not cope.

An attack on the apiary of the largest representatives of the wasp family - hornets - is critical. The striped giants are much larger than the bees. They easily tear apart prey, grabbing on the fly. A hive with honey and insects becomes an ideal food base for them.

Another enemy of beekeepers is a philanthropist or a bee wolf. It is a solitary wasp with a small size of 10-17 mm. She paralyzes her victim with a sting under the chin. This place is not protected by chitin and the poison quickly enters the main nerve node. Nectar is very harmful to philanthropy's offspring. He carefully crumples the killed victim with his paws, squeezing out the contents of the abdomen. The nectar is eaten by an adult, the body of the bee is given to the larvae.

Wasp sting - painful and dangerous

Insects use two types of self-defense. The first is a deterrent color. She signals to birds and reptiles about the poisonousness of wasps. As an active defense, they use a sting located at the end of the abdomen. Over the years of evolution, the ovipositor of females has evolved into a solid tube. The smooth organ does not get stuck in the skin, so the insect is capable of inflicting many bites. The sting is associated with a poison-producing gland. The chemical composition of the toxic substance differs depending on the genus of wasps. In case of danger, the insect releases a special enzyme that calls on the rest of the family for help. Having disturbed one individual, you can face the attack of the whole swarm.

Information. Insects with highly toxic venom include the Asian hornets. Their sting kills several people every year. Not fatal, but extremely unpleasant is the attack of road wasps. Their bite is in second place in terms of pain, second only to tropical ants.

After a bite, the following symptoms may appear:

• burning and itching;
• redness and swelling;
• headache;
• increased heart rate.

Attention. A bite in the neck area is extremely dangerous, it causes suffocation. People who are allergic to wasp venom can experience anaphylactic shock. They need to be taken to the hospital.

A stung person should be given first aid. The bite site is treated with an antiseptic - hydrogen peroxide, alcohol tincture. A cold compress is used to relieve pain and swelling.

How to kill stinging insects

No matter how great the benefits of wasps in nature, in some cases people have to go to extreme measures and destroy dangerous neighbors. To reduce the number of insects, special traps are used. These are homemade or commercial containers with sweet bait. Individuals that have flown into them cannot get out. You can get rid of the nest with the help of modern insecticidal preparations. Aerosol products - Dr. Klaus, Mosquitoll. Dichlorvos allow you to quickly and effectively destroy stinging insects. An effective way is to burn the nest. But using it under the roof of a house or on a tree will not work.

Everything that is created by nature has its own purpose. The beneficial insects of wasps should not be underestimated. Without these tireless hunters, the cities would have to fend off hordes of flies. In gardens, predators destroy harmful insects, allowing less use of chemicals.

Many do not even think about how dangerous bedbugs are for humans, except for the appearance of unpleasant painful bites implied by their presence. But in fact, painful bites are far from the only problem that bedbugs can carry to a person.

Unfortunately, few ordinary people know what insects of the bedbug family are, why their bites are dangerous and whether bedbugs themselves are dangerous. In view of this, we propose to consider in as much detail as possible what kind of insects are bugs and what dangers they are fraught with.

Harmful insect bug - an accurate description of the species

It is believed that bed bugs are representatives of the most common suborder of blood-sucking insects, attributed by biologists to the order of Hemiptera. Speaking about what the appearance of bed bugs is, we note that these harmful insects can reach the order of 3, 5 mm in length. Moreover, the size of an adult bug directly depends on age.

The development of a simple bed bug usually occurs through the so-called incomplete cycle of rebirth (or transformation). Namely: the female lays an egg, from which after a while a larva appears, which, in turn, gradually matures, turning into a large mature individual.

It should be said that, not being considered a source of infection, the bug is still capable, for a sufficiently long time period, to preserve pathogens of various diseases in its own body. Pathogens that may well, under certain circumstances, be transmitted to humans through blood. Such diseases, in particular, include:

• The viral etiology of hepatitis B.
• Tularemia.
• Plague.
• Q fever and others.

Of course, in medicine, extremely rare cases of the occurrence of dangerous infectious diseases that develop after a bite of a house bug are described, as well as in extremely rare cases, after a mosquito bite, malaria occurs. However, it is simply unacceptable not to know these facts.

Note that bed bugs with a prolonged lack of food (severe hunger) may well attack a person even during the day, although these cases are quite rare. Bed bugs do not have anything that closely resembles a nest, as, for example, ants do. Nevertheless, bugs still tend to organize some gatherings of individuals in places that are safe for them, always close to the main food source.

Such places of accumulation of adult bugs can be easily detected by the presence of dark spots of excrement belonging to insects, which are always found simultaneously with eggs and skins of larvae after molting. At the same time, bed bugs take root equally easily in any residential or warehouse space. And this absolutely does not depend on the cleanliness of the owners.

Despite the fact that it has not been reliably proven, the ability of bedbugs to tolerate disease, doctors do not exclude the possibility of transmission by bedbugs of microorganisms that cause brucellosis, smallpox, tuberculosis or typhoid fever. Some scientists working on bedbug problems are convinced that the dark feces of bedbugs, in turn, can contain the so-called Burnet's rickettsia (a family of bacteria that can cause typhus or spotted fever).

The greatest harm from bug bites

As we have already said, bedbugs deliver their greatest harm to humans by inflicting bites, thereby depriving us of normal rest. But, in some cases, numerous bedbug bites can lead to the development of a severe skin rash, a powerful allergic reaction and become a severe psycho-traumatic factor.

When attacked, bedbugs rarely bite a person only once. As a rule, the bug constantly moves along the human skin, leaving behind a whole "track" or "chain" of bites. At the same time, the distance between adjacent bites can be quite large, and can reach only a few millimeters, thereby forming extensive spilled spots on the skin. It is believed that with a strong infection of a dwelling with bedbugs, more than five hundred itching and swelling bites per night are possible.

Wasps: benefits and harms - which outweighs

Wasp - benefit and harm to humans

Wasps are a very common insect that humans associate with painful bites. At the same time, these insects may well bring not only harm, but also some benefit to human dwelling.

The main types of wasps:

Judging by the name, it is easy to determine that the representatives of the first group prefer to live independently. As for social wasps, they build nests for a large colony, which at the same time reproduces quite quickly. An impressive population of corresponding insects may well cause significant harm to humans. First of all, this concerns the high risk of attack. The fact is that wasps, in fact, regard any approach to their nest as an attack, to which they immediately respond with their aggressive actions.

Breeding features

To begin with, it should be understood that the entire swarm of presented insects lives for only one season. The next year, a new population appears. Before studying the wasp benefits and harms, it is necessary to study the main features of their existence, reproduction and vital activity. In the spring season, females are engaged in the manufacture of cells, in which eggs are subsequently laid. If we talk about single wasps, then the hatched larvae are able to develop independently. They live in outbuildings, warehouses and summer cottages. After the offspring has grown, they go to free bread.

Public wasps that live in families have their own uterus. It is she who is responsible for the construction of the nest. After infertile females are born, they are also involved in this process. The entire period of development from egg to adult lasts for one month. This information is as interesting as the wasp benefits and harms, which attracts the attention of the average citizen.

At the beginning of the development of the larvae, the uterus feeds them with pre-prepared sugary substances. In the future, the diet of future individuals expands due to the use of insects carefully chewed by females. Do not forget that the larvae may well consume certain foods found in the kitchen of a human dwelling. This is one of the main dangers of the creatures presented. In the most suitable conditions for existence, the number of one swarm of corresponding insects may well reach 1000 individuals.

Wasp benefit and harm

On the other hand, the positive moment described above continues exactly as long as the presented predator does not settle in the apiary in its own nest. Immediately after that, they are automatically reclassified as pests. The fact is that bees become the main delicacy for them.

Studying the wasp benefits and harms, it is necessary to understand that these creatures during the period of their short existence are still engaged in pollination of various plants. It would seem that this factor is positive. Nevertheless, the proximity of a wasp to a person is all undesirable early on. Many people who have previously encountered the corresponding problem will confirm this statement. First of all, the danger lies in the fact that wasps are very aggressive against those people and animals that even involuntarily approach their home. In this case, it is quite possible to become a victim of numerous bites, which in the future lead to the development of an allergic reaction and rather serious diseases.

The bites of the described insects themselves are very painful, as many members of society know about. In the event that their nest has formed very close to the living quarters, then people cannot escape the attack. It is better to immediately deal with this dwelling or seek help from qualified specialists. It is especially important to do this if small children live in the house. Due to the undeveloped immune system, they are primarily susceptible to the manifestation of the most serious manifestation of an allergic reaction. Their body may well face full-fledged poisoning.

Why wasps are needed - their role and functions in nature

Unlike their closest relatives, bees, wasps have not won love and respect from humans. They are not suppliers of honey, they make painful bites, and some even cause death of people. Therefore, the question involuntarily arises, why are wasps needed and whether there is any benefit from them in nature.

Exterminators of small insects

Adults feed on nectar, extract from fruits. But the larvae need constant replenishment of protein. To do this, wasps hunt other insects, including flies, mosquitoes, spiders, aphids, garden pests.

A fly is the easiest prey for a wasp

The flexible structure of the body, powerful jaws, a sting equipped with poison - all these things nature generously endowed the "minke whales" with for a reason. Thanks to this arsenal, they can sting the enemy from almost any angle. They cope with small weak opponents with the help of mandibles, crushing the skull or chitinous cover into small pieces. Wasps apply a sting to stronger insects, which, unlike bees, after an attack, they easily extract. Depending on the species, the composition of the poison is different and can either simply paralyze the victim, or provoke its death.

Scientists, answering the question of what wasps are for, say that without them a person would simply be horrified by the number of insects that exist in nature. First of all, this applies to flies, midges, beetles and spiders.

Garden helpers

Wasps play a significant role in nature, destroying garden pests. For example, Larra, a single burrowing wasp, helps in the destruction of a dangerous pest - a bear. She is absolutely indifferent to other insects and animals.

Despite the fact that the wasp is inferior in size to the bear, it easily deals with it

Larra hunts in a very peculiar and virtuoso manner. The insect drives the pest out of the ground and, through the sting, injects its poison into it. The wasp lays its egg in a paralyzed victim. Medvedka acts as an incubator for the development of offspring. While the larva is developing, the donor remains alive, supplying the young individual with all the necessary nutrients. After the last molt, the bear dies. Much attention is paid to breeding and attracting Larry's wasps to garden plots in the United States. For this, special studies are carried out to identify with what plants a useful wasp can be lured.

But slender insects help fight not only with bears. Giant scoli, in addition to pollination of flowers, regulate the number of bronzes, beetles, rhinoceros beetles. Like the wasp Larra, scolia lays eggs in its prey.

Tiny wasps Spilomena troglodytes destroy thrips. Other species with amazing diligence catch caterpillars of moths, leaf rollers, leaf beetles, bugs, cicadas, weevils, horseflies.

Adult wasps spend a lot of time on flowers

We must not forget that the functions of a wasp in nature are also in the pollination of plants and flowers, which is important for their development and reproduction.

Wasps in medicine

The venom of Brazilian wasps is unique in its composition. As a result of many years of research, it was revealed that the venom of the mentioned wasps is capable of destroying cancer cells without affecting healthy tissues. The reason for this phenomenal action lies in the special structure of the protein, which, interacting with the fats of cancer cells, converts them into a liquid substance.

It is already reliably known that the venom of the Brazilian wasp has been shown to be effective against cancer of the prostate, bladder and blood.

Now scientists are working in laboratories to create a synthetic analogue of a unique protein. It is possible that in a few years mankind will receive a universal cure for cancer.

Wasps - protectors of weak insects

Without knowing it, wasps indirectly protect other insects. Hunting abilities, aggressive disposition, deadly sting force other representatives of the fauna to refrain from contact with the striped predator. Weaker individuals took note of this attitude towards wasps and "borrowed their colorful outfit."

Perhaps no insect has as many imitators as wasps. The striped color helps to protect themselves from birds and predators for hoverflies, beetles, butterflies and many other harmless creatures.

The benefits and role of wasps in nature should not be underestimated. Urban individuals regulate the number of flies, carrying millions of dangerous bacteria on their paws. In household plots, they help get rid of garden pests without resorting to the use of chemicals. A wasp attacks a person only when it feels an outgoing threat. If you do not panic at the sight of her, do not wave your arms vigorously and do not try to kill her, a bright insect will fly by and do no harm.

Wasp venom: is it good for the human body and how it works

The composition of the wasp venom is close enough to the bee venom. In addition, many bitten people cannot even say unequivocally whether a wasp stung them, or a bee - the effects of the poison on the affected tissues are so similar.

Today, scientists have managed to study the composition of both bee and wasp poisons well enough. At the same time, an important distinctive feature was established: the wasp venom is somewhat more allergenic and often leads to complications in the form of various manifestations of dangerous allergic reactions (for example, Quincke's edema, anaphylactic shock). However, one should not think that from this point of view, bee venom is harmless - it is also “a lot” for it, just with a little less probability.

Partly for this reason, "condemnation" is not generally known as a traditional medicine method. Despite the fact that bee sting is a fairly common and widely known procedure.

On a note

Among experts, there is an opinion that the notorious apitherapy and the benefits of bee venom are nothing more than a marketing ploy by beekeepers who need to sell their surplus products. No serious research has confirmed, for example, the benefits of bee sting, as well as the healing properties of other methods of apitherapy.

With a high probability, the benefits of propolis, wax moth, royal jelly and bee venom are nothing more than a placebo effect, and these beekeeping products became widespread precisely because of their availability: they can be obtained in apiaries in almost any quantity.

But it is extremely difficult to get wasp poison, because no one bred them on purpose, and you need to climb into the nest of wild wasps for the drug. And this is another explanation why, despite the similarity of the compositions, the poisons of these closely related insects differ so much in popularity in folk medicine.

As a result, even physicians and toxicologists cannot always say unambiguously today whether wasp poison is useful for humans. It does contain stimulating and tonic components, substances that stimulate metabolism, but it is not rational to isolate them from the poison - there are many much safer analogues of both natural and synthetic origin on the market today.

But due to the large number of harmful and allergenic components, it can be very dangerous to use unprepared wasp poison for treatment.

The composition of wasp venom and the effect of its components on the human body

In the overwhelming majority of cases, wasps use their sting primarily for self-defense, and only in rare cases - to kill larger and too aggressive prey. Therefore, as a rule, the main purpose of a wasp bite is to cause severe pain in the victim and scare them away.

The composition of wasp venom includes a set of substances that have a strong effect on nerve endings and cause a rapid immune response in the body. Among the main components, the following components can be distinguished:

In hornets, the venom also contains specific mastoparan toxins, which have a powerful destructive effect on cells.

“I had one time that a hornet stung. I'm used to bee stings in the apiary, they don't bother me at all, I boldly catch and crush philanthropists. But the hornet scored so much that it already darkened in his eyes. Well, I had all the evidence closed. I just reached the trailer and lay down to lie down. The pain was hellish, my heart was already grabbing, I just thought to put something cold on my hand. It smashed it great, to the very shoulder, it itched a lot. A neighbor in the apiary offered to take me to the hospital, but nothing happened. The next day, only the itching remained, and then gradually the swelling began to subside. "

Mikhail, Semipalatinsk

Consequences of the action of wasp poison on the human body

Now let's see how the wasp venom works, so to speak, at the macro level, that is, what symptoms arise in this case.

At the time of the sting, the effect of the poison injected under the skin causes sharp pain, and almost immediately leads to the appearance of a slight pale edema at the site of the bite. After a few minutes, the bite swells more, may turn red, become hard, and a sensation of severe itching appears on the skin in its area. At this time, the first symptoms of allergies may appear - hives, fever, shortness of breath, headache, confusion.

The most severe consequence of a wasp sting is anaphylactic shock - an extreme degree of allergic reaction. It occurs rarely and only in people who are hypersensitive to the venoms of hymenoptera insects. But it is precisely because of anaphylactic shock that the number of deaths from bites of wasps and hornets is so high. Such a reaction develops very quickly, literally within a few minutes after the bite, and sometimes the victim does not even have time to be taken to the hospital.

By and large, the benefits of wasp venom, even if there is one, are completely covered by the risk of a dangerous allergic reaction (especially when you consider that with each next bite, the body's sensitivity to the poison may increase).

“People are regularly brought to our hospital and attacked by huge hornets. There are many beekeeping farms in the area, and hornets actively inhabit all the surrounding forests, as they constantly fight with bees. Usually, after a bite, the patient develops a severe allergy, limited to swelling and rashes on the skin, fever and pain in the head may appear. But sometimes there are severe cases, with hemorrhages, laryngeal edema and anaphylaxis. Last year, for example, there were two deaths, and a 12-year-old girl died in one. "

Naomi Kurosaki, Saito

But after special processing in the laboratory, wasp poison can become much safer and more useful.

The use of wasp venom in medicine

It is for allergy sufferers, in whom wasp bites lead to serious consequences, that special vaccines are prepared on the basis of wasp poison. They reduce the titer of histamine and some toxins, but retain the initial amount of specific components by which the human immune system can identify the poison.

Before the warm season of the year, when it is likely to be stung, the patient is vaccinated to develop a normal immune response to the bite. As a result, after an accidental meeting with a wasp, the reaction to a sting in humans will be much less pronounced and not so life-threatening.

Wasp poison can also be useful due to the actual toxins that make up it. So, for example, in Barcelona, ​​a long time ago, the development of a method for combating cancer tumors, based on the defeat of cancer cells by the biological components of wasp poison, has begun.

Scientists are trying to combine toxin molecules with transport protein molecules that will carry poison directly to cancer cells without affecting healthy ones. In mice, such a drug has already proven its effectiveness, and work is currently underway to study its effect on human tissue.

The most poisonous wasps in the world

Although all wasps are poisonous, the strength of the poison and the effects of the bites differ from one type of wasp to another. In different representatives of the suborder, the ratio of the components of the poison can vary greatly, and many of them have unique components in the venom that have a specific effect on the victim.

So, for example, the most painful bite of the roadworms of the genus Pepsis. Most members of this genus specialize in harvesting tarantulas for their larvae. Their bite is considered one of the most painful insects in the world, and in its strength is second only to the bite of the South American ant Paraponera clavata.

The bite of a huge hornet (Vespa Mandarinia) that lives in Southeast Asia and Japan, according to statistics, is the most dangerous among representatives of wasps. Annually, about 40 people die from the attacks of these insects in Japan alone, and the number of victims in the entire habitat of these hornets exceeds a hundred.

The composition of the venom of a huge hornet differs little from the composition of the venom of the European hornet, but in one bite the insect introduces a much larger dose of toxins into the human body. In addition, when attacking, the hornet can make several stings at once with a small interval, which often leads to further hemorrhages and extensive edema. We can say that the huge hornet is the most poisonous wasp in the world.

But scoliosis wasps, despite their truly gigantic size, sting rather weakly. Their venom is designed to paralyze prey, and not scare away the enemy, and therefore entomologists boldly catch these large black wasps with their bare hands.

And in conclusion, we note once again: it is still not worth expecting that the wasp's poison will be useful for the body. In case of an accidental sting, this, of course, could be a little consolation, but you should not specifically catch wasps and apply them to the body, because even the possible positive effects of a bite will be overridden by severe pain, unpleasant swelling and the risk of developing a dangerous allergic reaction.

On a note:

The bites themselves can cause various diseases and disorders, not to mention the fact that these little vampires can deprive you of proper sleep and rest!

In order to live and reproduce, bed bugs, like all living things, need good nutrition.
And as you know, house bugs feed mainly on human blood, and with their bites they can turn life into a real nightmare, and not only at night, depriving full sleep and rest, but also in the daytime, since the bite sites often itch, itch, thereby causing tense nervous state.

Feedback from our readers:

“Like all newlyweds, having got married, we decided to live separately. My wife and I looked at the apartment and rented it. And not cheap! And there are bugs! The wife, out of inexperience, thought cockroaches. In general, we often did not get enough sleep, became nervous, irritable, trifled over each other, almost got divorced! As soon as we changed housing, our life got better))) It's good that they didn't bring this abomination to the new apartment with us, and then sit around and guess where the bugs come from in the house ... "

Denis, Khabarovsk

On a note:

If you feel the bug bites, then this is most likely its larva, since it does not have enough of the enzyme that is responsible for the painlessness of the bites.

Bed bug bite photo

The photo clearly shows how the bug bit. The thing is that one bug bites several times during one feeding, thereby leaving a peculiar line of bites on the skin. Having bitten once, the insect moves a short distance and bites again and so on until it is full. This nature of the bites suggests that it was the bed bug that bit it. On average, one bloodsucker is capable of leaving 5 to 7 bites on the victim's body.

People who are susceptible to allergic reactions, such a neighborhood can threaten such consequences as: constantly itchy blisters, which, when healed, can leave ugly scars on the body. Also, if you scratch the bites, then a secondary infection can join the wounds, causing severe pustular inflammation on the skin, requiring special treatment in the future. This is especially true for young children who simply cannot stand it!

If a person has increased individual sensitivity, then the allergic reaction can turn from a common rash into a headache with nausea, fever and swollen lymph nodes.

In general, bed bugs significantly reduce the quality of life, bringing a lot of trouble and trouble with their presence, especially biting children!

What is the danger of bedbugs for children?

For children, the danger of bed bugs lies primarily in the fact that, due to the immaturity of the skin, the itching turns out to be especially painful and unbearable, and if an allergic reaction also begins, then it usually becomes protracted and difficult to treat. This is due to the fact that the child's immune system is still being formed.

It is known that multiple bites over time can cause iron deficiency anemia in children. Therefore, if you suspect blood-sucking bugs at home, immediately start fighting them, especially since today there are many means for this!

Do bed bugs carry diseases

In addition to all of the above, there is an assumption that bedbugs are capable of transmitting various infectious diseases. First of all, this concerns the immunodeficiency virus.

Scientists have carried out research on this subject and it has been experimentally proved that the viral particles of this disease can accumulate in bedbugs in the digestive tract. However, the immunodeficiency virus itself does not multiply in the body of the bug and does not even stay for a long time and is excreted along with the insect's feces.

In addition to the immunodeficiency virus, bedbugs are capable of carrying pathogens and many other infectious diseases in their bodies. First of all, these are:

• Tularemia
• Leprosy
• Typhus
• Q fever
• Relapsing fever
• Filariasis
• Leishmaniasis
• Syphilis
• Tuberculosis
• Yellow fever
• Hepatitis B

Being carriers of such serious diseases, for the entire time of research, scientists have also not identified a single case of transmission of infection from one person to another when bitten by these insects.

It is interesting:

The tropics are home to insects known as triatomaceous bugs, which have the ability to transmit Chagas disease, which is caused by the simplest species of trypanosomes. In the early stages, the disease almost does not give itself away. Many do not even know that they are sick. And only in 30% of the population, the causative agent of this disease causes serious health problems. The bed bug can also carry the disease without having the ability to transmit infection.

How bed bugs affect the psychological state of a person

The consequence of constant lack of sleep is not only depletion of the nervous system: in this case, a person becomes irritable and aggressive, but in addition to everything, the body's defenses are reduced, which provokes frequent illnesses and even the development of a nervous tic.
