The class of insects is the most numerous and many-sided on our planet. Scientists have described just over 600 thousand species, but apparently the whole life of our civilization is not enough to study them all. According to rough estimates, the Earth is inhabited by two to four million species of insects. They are very different - microscopic and palm-sized, colorful and inconspicuous, beautiful and ugly for our eyes. But there are those with whom meeting may be the last for humans, because these creatures carry a great threat.
But there are those with whom meeting may be the last for humans, because these creatures carry a great threat.
Malaria mosquito, or anopheles (genus Anopheles)
This insect came in first place because it becomes an indirect cause of death of hundreds of thousands of people every year. Malaria is dangerous because it affects many vital organs of the person - the cardiovascular system, liver, brain, lungs, causes fever attacks and anemia.
By the way, a malaria mosquito is not a source of pathogens, but only transfers it from person to person. For example, if you grow this insect in the laboratory, it will be absolutely safe.
Malaria mosquitoes are similar to mosquitoes familiar to us, only they are larger and their legs are longer. The insect is distributed around the world, except for the coldest regions, where there are no living conditions for insects. The most serious foci of malaria are found in the hot, poor countries of Africa, the Americas and Asia. In fact, you can catch this disease almost everywhere. And the thing is that the malaria mosquito is a genus with about 400 species.
The death rate from malaria is enormous. In the 20th and even the beginning of the 21st centuries, up to half a billion people were infected with this disease every year, and more than a million died. Today, thanks to the intensified fight against malaria, mortality from it has dropped to 400 thousand per year. In 2015, Yuu Tu, a Chinese scientist, received the Nobel Prize for discovering a new cure for malaria.
Tsetse fly (genus Glossina)
Tsetse is not a species, but a whole genus of insects, numbering 23 species. She is rightfully considered the deadliest fly in the world, because it is dangerous for both humans and animals. Tsetse suffers from a disease called carotid (for humans) or Nagan (for animals). True, not all species of these flies are dangerous to humans, but it is better for animals not to meet them at all.
In fact, wild animals of Africa are the source of pathogens (trypanosomes), and flies are only its carriers.
Tsetse flies and sleeping sickness are the scourge of tropical regions of Africa. The black continent had a hard time - in vast territories it is difficult to live because of the hot sands of the desert, and the most fertile rainforests are infected with hordes of deadly flies.
At one time, they tried to fight them in a rather cruel way - they considered that having destroyed all wild animals, they would deprive the fly of tsetse food, and it would disappear. The beginning and middle of the twentieth century were marked by the genocide of African wild animals, during which some species were completely destroyed. The fly receded, but not for long.
Africa has now improved thanks to clearing the jungle, urbanization and surveillance. But even so, up to 7 thousand people die from the disease every year.
Symptoms of sleeping sickness are insomnia, fever, fever, headaches, swollen lymph nodes. The nervous and immune systems are affected, a person loses touch with reality. A further scenario for the development of the disease is convulsions, epileptic seizures, coma and death. Without treatment, almost all infected die.
Drugs for treatment are very toxic, so you can not get infected with it in any case. The main recommendation for the prevention of sleeping sickness is that you do not need to travel to Africa unless absolutely necessary.
Africanized Bee (Apis mellifera scutellata)
Once, Brazilian breeders in an attempt to develop a new species that brings a lot of honey and is more resistant to disease, crossed a European honey bee with African wild bees. Indeed, the fruits of their labors are strong, hardy, hard-working insects that can adapt to different climatic conditions. They can bring 2 times more honey than an ordinary bee, are excellent pollinators. But they took over from their African ancestors the evil traits of character - aggressiveness and irritability.
If a person or animal appears near the nest of a European bee, the insects will behave relatively peacefully, defending themselves only if the uninvited guest reaches into the hive. Having driven off the enemy, they calm down. Africanized bees consider sworn enemies of anyone who is within a radius of 5 meters from the hive - they can chase a victim for several kilometers, mercilessly stinging the fugitive until he falls dead. Salvation in the water does not help much - angry warriors can wait for a long time by the water. If the European bee calms down within an hour after the skirmish, then the African relative is excited for another eight hours.
Since the advent of the new species - the end of the 1960s - about 200 people have died, several thousand were injured, tens of thousands of domestic and wild animals have died.
The venom of an Africanized bee is more toxic than that of a regular bee, but their cohesion is especially dangerous - even a person who does not suffer from allergies dies from anaphylactic shock, receiving a hundred bites.
Human Skin Gadfly (Dermatobia hominis)
The method of breeding this large fly is not only dangerous to human health, but also causes extremely unpleasant emotions. Larvae of the gadfly feed on body tissues, causing purulent abscesses and bringing wild pain to their “cradle”. We can say that the victim was lucky if the gadfly larvae invaded under the skin of the abdomen, back, arms or legs. But they can also appear in the eyes (this often ends with a complete loss of vision), genitals, and mucous membranes of the mouth. There were times when a larva was found in the brain of an already dead person. This creature is more terrible than cinema zombies that feed on the brain, because it is real. Br-r!
The gadfly does not infect human larvae directly. First, he catches some blood-sucking insect (for example, a mosquito) and lays eggs on it. When the “messenger” sits on a person, the larvae feel warmth and crawl onto the new host, bite through their skin and set up an incubator for themselves.
The human gadfly lives in a number of countries in Central and South America. The person who has visited there needs to be especially careful about the red festering carbuncles that have appeared on the body - this is exactly what the larvae growing under the skin look like.
Japanese giant hornet (Vespa mandarinia japonica)
This endemic of the Japanese archipelago is recognized as the largest among all species of hornets - an unfriendly insect can grow up to 5 centimeters. It is so large that the Japanese call it the "sparrow fly."
Those who have been stung by the Japanese hornet at least once will forever remember these feelings - a hellish, incomparable pain. Even the bite of one such adversary can cause severe anaphylactic shock. And the attack of several hornets often ends in hemorrhages, tissue necrosis and death. This statement is not unfounded - in Japan, about forty people die every year from the bites of a giant hornet.
Lonomia (Lonomia obliqua)
Caterpillars of this butterfly are considered the most dangerous in the world, because they have the most toxic poison. The inhabitants of South America, where lonomia is found, are saved from imminent death only by a small amount of poison injected under the skin - only one thousandth of a snake dose.
However, a meeting with one caterpillar leads to severe burns, after which bruises, bruises and gangrene remain on the human body. Seeing the victim, you might think that someone beat him. There are cases when a person died from contact with several individuals.
Worst of all, the lonomies are great disguises. The butterfly looks like a yellow fallen leaf, and the accumulation of caterpillars can not be distinguished from grayish-green moss. A tired tourist leans against a mossy tree trunk - and that’s it.
Megalopygids (fam. Megalopygidae)
This is a family of butterflies that live in Mexico and the United States. Especially dangerous are their tracks. These fluffy pretty creatures have poisonous spikes hiding under their skin. The result of their injections is severe pain at the site of contact, pulmonary edema, headache, vomiting. The thorns of megalopigids are removed from the wound with adhesive tape - if you do not do it on time, the effect of the poison is exacerbated. Without medical attention, a meeting with several tracks can be fatal.
It is especially sad that they have an attractive appearance, as if beckoning: “we are so fluffy, stroke us!” Because of this, children who like to touch everything so often become victims of megalopygids. It is not easy for foreigners, who are embarrassed by their beauty. But locals call them "fire creatures" and bypass the tenth road.
Nomadic Ants (Eciton burchellii)
These strong insects, one and a half centimeters in size, fully justify their name. They are fearless, disciplined, strong and. absolutely blind. Possessing huge jaws, ants are able to gobble up any creature that is on their way in a matter of hours. Sick, slow and simply carelessly sleeping animals will inevitably be eaten.
Another reason for their name lies in the fact that soldier ants do not build nests. They stalk the deadly hordes of conquerors on the ground, stopping only briefly so that the female can lay eggs. As soon as new soldiers hatch from them, the convoy will continue its course.
In general, once in the Amazon, where these insects live, do not go to bed on the ground.
Paraponera or "ant-bullet" (Paraponera clavata)
In order to get acquainted with this ant, you need to talk about a person who subjected his body to the bites of more than 150 species of flying and creeping creatures. Justin Schmidt created a whole scale of pain, where each sting of an insect was rated from 1 to 4 points. The only one who received 4+ turned out to be a bullet ant. He was so named because the bite is comparable to a gunshot wound and rightfully takes first place among the most painful.
The bullet ant reaches a size of 2.5 centimeters and lives in the tropical forests of South America. Small colonies of a thousand individuals settle in nests that grow on trees.
The result of a bite of such an ant is convulsions and paralysis of a stung part of the body. After an attack of several individuals, a person can die either from pain shock or from an allergic reaction. The danger of this insect is reduced due to the fact that the bullet ant is quite peaceful in nature and will never attack without extreme need. If a stranger stares at the nest, the defenders will first try to scare him away with a hiss and an unpleasant smell, and only then they will attack.
Road Wasp (fam. Pompilidae)
They also ended up on the Schmidt scale, where they took an honorable second place. These dangerous "ladies" are found in Thailand and exceed the size of the Japanese hornet mentioned above - their length is more than five centimeters. Survivors of their bite say that this pain deprives the mind and resembles an electric shock. At first, the victim can only ride on the ground and yell violently. Pain can last up to three days, a severe allergic reaction, swelling. Allergy sufferers and people with a low pain threshold are at risk - for them, a meeting with road wasps can be fatal.
The roads of these "babies" are called because they most often attack people on the tracks, provoking an accident - a stung driver loses control of the pain. It is reassuring that meeting with them is rather rare, so there are not so many chances to become a victim of road wasps.
Strange, you can say by reading this collection. Why isn’t there dangerous creatures like encephalitis ticks, spiders, scorpions? Recall that all these species belong to the arachnid class, arthropod type, that is, they are not insects. Skolopendra also didn’t get into our top - for the same reason, because their class is called "Gubonogoda".
Interestingly, an insect alone is not capable of causing serious harm to humans. They become fatal in conjunction with other factors - diseases, allergies, or in the case of a large number of attacking individuals.
Brazilian wandering spider
Also known as Phoneutria, Brazilian wandering spiders are poisonous creatures that live in tropical South America and Central America. In the Guinness Book of World Records in 2010, this type of spider was called the most poisonous spider in the world.
Spider venom of this genus contains a powerful neurotoxin known as PhTx3. In lethal concentration, this neurotoxin causes loss of muscle control and breathing problems, leading to paralysis and ultimately suffocation. A bite of moderate pain, the poison causes an instant infection of the lymphatic system, getting into the circulatory system in 85% leads to heart failure. Patients feel wild rigor mortis during life, sometimes causes priapism in men. There is an antidote on a par with antibiotics, but because of the serious harm to the body with poison, the detoxification procedure is actually equal to the victim's chance of survival.
Termites do not pose a direct danger to humans, they play an important role for the environment, moreover, in some cultures they are even eaten. But at the same time, termite babies can cause enormous damage to infrastructure, sometimes making houses completely unsuitable for housing.
Lice are wingless parasites that feed on skin particles, blood and other secretions of the human body. Most often, people are carriers of these insects, and in nature there are approximately fifteen different types of lice. Despite the fact that, like termites, lice do not always pose a direct danger to human health, they can be carriers of diseases.
Each year, the black-footed tick infects thousands of people with Lyme disease, which begins with a rash around the bite that resembles a bull’s eye. Early symptoms of this disease include headache and fever. With the further development of the disease, the victim also begins to suffer from problems with the cardiovascular system. Few die from these bites, but the consequences can continue for many years after an unpleasant encounter with a tick.
The first creature on our list that is dangerous in the literal meaning of the word is roving ants, known for their predatory aggression. Unlike other species of ants, stray do not build their own permanent anthills. Instead, they create colonies that migrate from one place to another. These predators constantly move throughout the day, hunting insects and small vertebrates. In fact, an entire colony can kill more than half a million insects and small animals in one day.
Despite the fact that most wasps do not pose any particular direct danger, certain varieties of them, such as the German wasp of North America, are large and can be incredibly aggressive. If they feel a danger or notice an invasion of their territory, they can sting repeatedly and very painfully. They will tag their aggressors and in some cases pursue them.
Despite the fact that the sting of a Black Widow spider female can be very dangerous for humans due to neurotoxins released during a bite, if the necessary medical care is provided in time, the consequences of the bite will be limited to only some pain.Unfortunately, isolated deaths from a Black Widow bite did occur.
Despite the fact that these Megalopyge opercularis caterpillar tracks look cute and fluffy, do not be fooled by their cartoony appearance, because they are extremely poisonous.
Usually people believe that the hairs themselves are burning, but in reality the poison is released through the spikes hidden in this “coat”. The spikes are extremely brittle and remain in the skin after touching. The poison causes a burning sensation around the affected area, headache, dizziness, vomiting, sharp abdominal pain, damage to the lymph nodes and, sometimes, respiratory arrest.
One of the most famous bugs, the cockroach is known as a carrier of many diseases dangerous to humans. The main danger of living together with cockroaches is that they climb into the toilet bowls, garbage cans and other places where bacteria accumulate, and as a result, they are carriers. Cockroaches can be the cause of many diseases: from worms and dysentery to tuberculosis and typhoid. Cockroaches can carry fungi, unicellular organisms, bacteria and viruses. And here's a fun fact - they can live for months without food and water.
Parasitic worms are a type of eukaryotic parasite. Most parasitic worms are known to live in the digestive tract of humans and cause insomnia, vomiting, nausea, and many other health problems.
A person does not directly feel the bug bite itself, since the anesthetic is included in the saliva of the bug. If the bug could not get to the blood capillary the first time, it can bite a person several times. At the site of the bug bite, severe itching begins, and a blister may also appear. Occasionally, people experience a severe allergic reaction to a bug bite. Fortunately, 70 percent of people feel almost no consequences from them.
Bed bugs are household insects and do not belong to the group of carriers of infectious diseases, but in their body they can retain pathogens that transmit infections through the blood for a long time, they include: viral hepatitis B, pathogens of plague, tularemia, Q-fever can also persist. They deliver the greatest harm to people with their bites, taking away a person’s normal rest and sleep, which subsequently can adversely affect moral health and performance.
Human gadflies have larvae that can transmit life-threatening parasites to humans. Also known as torsalo, human gadflies are usually transmitted by mosquitoes. When a mosquito carrying the larva of a human gadfly lands on the skin, it larva enters the host organism. After several days, it grows under the skin and can cause a serious infection if the mosquito bite is not treated immediately.
Centipede (Scutigera coleoptrata). This insect, which is also called the flycatcher, appeared supposedly in the Mediterranean. Although other sources talk about Mexico. Centipede has become very common around the world. Although the appearance of such insects is unattractive, they generally perform useful work, as they eat other pests and even spiders. True, with entomophobia (fear of insects), such an argument will not help. People usually kill them because of their unpleasant appearance, although centipedes are even protected in some southern countries. A flycatcher is a predator, they inject poison into the victim and then kill it. Often flytraps settle in apartments without harming food or furniture. They love moisture, often centipedes can be found in basements, under bathtubs, in toilets. Flycatchers live from 3 to 7 years, newborns have only 4 pairs of legs, increasing them by one with each new molt. Usually, the bite of such an insect is not disturbing for humans, although it can be compared with a small bee sting. For some, this can even be painful, but usually it is limited to tears. Of course, centipedes are not insects that are responsible for thousands of deaths, but many of us will be surprised to learn that every year someone dies from these bites. The fact is that an allergic reaction to insect venom is possible, but this still happens extremely rarely.
Despite the fact that scorpions are not insects, since they belong to the order of arthropods from the class of arachnids, we still included them in this list, especially since black scorpions are among the most dangerous types of scorpions. Most of them live in South Africa, especially often they can be found in the desert. Black scorpions differ from other species in their thick tails and thin paws. Black scorpions sting, injecting poison to their victim, which can cause pain, paralysis and even death.
Another bloodsucker is the Predator, aka Assassin bug, aka Reduviidae. Their main diet consists of insects and their larvae, but some tropical species are not averse to drinking blood from small animals and even humans. A predator responsible for the transmission of Chagas disease, this parasitic beetle often infects people living in poor rural areas.
Paraponera clavata is a species of large tropical ants from the genus Paraponera Smith, and the subfamily Paraponerinae (Formicidae), which have a strong sting. Called an ant by a bullet for the reason that the victims of the bite compare it with a shot from a pistol.
A person bitten by such an ant can feel throbbing and relentless pain during the day after the bite. In some local Native American tribes (Satere-Mawe, Maue, Brazil), these ants are used in very painful rites of initiation of boys to adulthood (which leads to temporary paralysis and even blackening of stung fingers). In the course of studying the chemical composition of the poison, a paralyzing neurotoxin (peptide) called poneratoxin was isolated from it.
Malarial mosquitoes or anopheleses are a genus of diptera insects, many of which are carriers of human parasites - malarial plasmodia. A mosquito becomes infected with plasmodium malaria from a human patient or carrier. Plasmodium falciparum undergoes a sexual reproduction cycle in the mosquito. An infected mosquito becomes a source of infection for a person 4-10 days after infection and is such for 16-45 days. Mosquitoes serve as carriers of other types of plasmodia that cause malaria in animals.
Rat fleas are one of the most dangerous flea species (Pulicidae), a plague carrier. They are parasites of rats (Rattus, Nesokia) and gerbils (Gerbillinae). They are carriers of Plague bacillus (Yersinia pestis) and Rickettsia typhi, as well as intermediate hosts of parasitic worms of rat Hymenolepis diminuta tapeworm and mouse Hymenolepis nana tapeworm. Diseases can be transmitted from one generation to another through eggs.
African honey bee
African bees (also known as killer bees) are descendants of bees brought from Africa to Brazil in the 1950s in an attempt to improve honey production in this country. Some African queens began to interbreed with local European bees. The resulting hybrids have moved north and are still found in southern California.
African bees look the same, and in most cases behave like European bees, who currently reside in the United States. They can only be detected by DNA analysis. Their stings are also no different from ordinary bees. One very important difference between the two species is the protective behavior of African bees, which is manifested in the protection of their nests. In some attacks in South America, African bees killed livestock and people. The AMP earned the nickname “Killer Bees” by this behavior.
In addition, this type of bee is known for acting like an invader. Their swarms attack the hives of an ordinary honey bee, invading them and setting their queen. They attack in large colonies and are ready to destroy anyone who encroaches on their uterus.
These “pets” are ubiquitous, choosing warm rooms for living next to food and water. They feed on human products, and in the absence of those, they can eat paper and leather products. A red cockroach is dangerous in that, moving around different areas of residential premises, including garbage cans, sewers, etc., it carries many dangerous bacteria and helminth eggs on itself. Such a neighborhood threatens a person with the development of various diseases, including dysentery, meningitis, salmonella and others.
Refers to insects parasitizing on the body of humans and animals. Settled in living quarters to constantly be near the power source. Bedbugs attack people mainly at night, and during the day they hide in secluded places. The bite of this tiny insect, which is difficult to see, causes an unpleasant itch and can lead to allergies.
This type of flea poses a serious danger to humans. Parasitizing mainly on rats, they transmit plague bacillus, tularemia, encephalitis and other diseases from animal to animal. And rodents, in turn, easily spread the infection further, infecting a person. In rare cases, fleas bite pets and people. In addition to the pain and itching at the site of the bite, a person may experience a headache, fever and other unpleasant symptoms.
These small parasites that feed on human blood, depending on the location of the dislocation on the body, are of 2 types: head and body. Head lice are practically harmless, although cohabitation with them gives people considerable discomfort. Their bites cause irritation of the scalp, various infections can get through the wounds. Born louse is the main carrier of a deadly disease - epidemic typhus.
Red fire ant
The bite of these insects is similar in sensations to a burn from a fire, in connection with which they were given such a name. This species of ants, originally inhabiting only Brazil, was randomly brought to different parts of the planet, where it successfully adapted and adapted to life in new conditions. The poison of a red ant secreted by a bite can provoke an allergic reaction, even death.
These ants lead a nomadic lifestyle. They move from place to place with the whole big friendly family, the journey takes about 2 weeks. The ants make stops only for the female to lay eggs and new members of the community appear from the previously formed pupae. The habitat of nomadic ants is the African continent, countries of Asia and South America. The bite of such a nomad is deadly only to people prone to allergies. Another nuisance from these insects is that they sweep away everything in their path, including livestock.
These insects are common in southern Europe and Russia, in northern Africa and in China. They belong to gray meat flies, which are characterized by reproduction in the corpses of animals. It is this feature that poses a threat to domestic animals and humans, since a fly can put its larvae into a wound, cut or mucous membranes. Developing, the larvae begin to eat living tissue and human muscles. Moving inside the body, they cause pain, in the place where they are populated, there is a swelling and suppuration.
Another fly whose larvae develop in the human body. This species of flies is widespread on the African continent and in Saudi Arabia. The insect lays eggs on sand or on clothes soaked in urine or sweat, and the larvae patiently wait for their future carrier. Upon contact with human skin, they begin to actively screw into it, as a result of which tropical myiasis develops on the body. Thus, the larvae sit in the human body for up to 15 days, and then go out and go to pupate in the ground.
This shaggy caterpillar of a species of moth was recently called the caterpillar of Donald Trump, for its similarity to its hair. But the cute and fluffy look of this insect is misleading. The wool under which the body of the caterpillar is hidden consists of hairs with poisonous spikes. If a person decides to stroke a caterpillar, he risks getting a powerful toxic injection. When in contact with human skin, the thorns dig into it and break, and the poison causes a strong burning sensation. Particularly susceptible people may experience dizziness and vomiting. These insects are common in the United States, Mexico, and northern Central America.
This insect is a large parasite fly. Worldwide, there are more than 170 species of gadflies, of which only one will attack people - Dermatobia hominis, who lives in Central America. It is a common misconception that gadflies bite very painfully. In fact, they have neither mouth nor teeth, so this is simply physiologically impossible. The danger of these insects lies in their larvae, which at the initial stage develop only in the human or mammalian body. Once in the body, the larvae begin to actively eat flesh and muscles, causing myiasis.
A butterfly caterpillar from the peacock-eye family can be found in rainforests, orchards and village gardens in some Latin American countries. The body of the caterpillar is covered with poisonous spikes that easily pierce human skin. After contact with lonomia, a toxin enters the bloodstream, which reduces its coagulability. After a short period of time, a person develops internal bleeding, hemorrhage in organs, including in the brain, which can lead to death.
For the manner of biting into the area near the lips of this bug is called kissing. Triatomous bugs live in Central and South America. This blood-sucking insect is a carrier of dangerous parasites that cause Chagas disease. After a “kiss”, a person may experience the first symptoms of a disease: fever, headache, swollen lymph nodes, and others. After a few weeks, the disease goes into a chronic stage. At an early stage, it lends itself well to treatment, in the absence of medical care it can lead to the death of the patient.
Under this name, a small group of insects from the suborder of bellied bellies is combined. They are distributed throughout the globe, except Antarctica. Almost all wasps have a poisonous sting, which, unlike a bee sting, does not deteriorate after the first use. A person stung by a wasp will feel a sharp pain in the place where the sting penetrated. There is also redness and swelling. In people with allergies, the consequences of a bite can be more serious, even fatal.
These large flies live on all continents except Antarctica. Being blood-sucking, horseflies actively attack domestic animals and people. Insect saliva contains toxic substances and anticoagulants, so a person’s bite site does not heal for a long time, the wound can bleed. A horsefly bite causes burning pain and swelling, in some cases it can cause an acute allergic reaction. It has been scientifically proven that horseflies are carriers of dangerous diseases, including tularemia, tick-borne encephalitis, anthrax and others.
From the name it is clear what disease this insect spreads. The existing malaria vaccine is ineffective, about 500 thousand people die from this disease every year. Mosquitoes inhabit almost the entire globe, except for Antarctica. The most dangerous species in terms of the transmission of infectious diseases inhabit tropical territories.The largest number of infections is recorded in African countries, mainly children under 5 years old.
One of the most dangerous members of the ant family. In its arsenal is toxic poison, which cannot be compared with wasp or bee. These ants live in large families in the tropical forests of Central and South America. The bite of a bullet ant is considered the strongest on the Schmidt sting scale. A person may experience pain during the day. Edema also forms at the site of the bite, and a temporary numbness of the bitten limb is possible.
Belongs to the family of real wasps, being the largest representative of the hornet genus. It lives in Asian countries and in the eastern part of Russia. Hornets are extremely rarely attacked by people, only for self-defense. Extremely painful bite of this insect causes edema, redness, can provoke an allergic reaction, and, as a result, lead to death. Simultaneous bites of several individuals at once can kill even a healthy person who does not suffer from allergies.
Poison-soaked ant is ready to sting without warning. He will methodically bite his victim until he dies. Ants of this species live in North America. The power of their sting on the Schmidt scale is close to maximum. It is noteworthy that when an ant deals with its prey, in addition to toxic substances, its poison emits a special anxiety pheromone that alerts other members of the colony about the danger and encourages them to unite in the fight against the enemy. For a person, such an organized attack can be deadly. From a bite of only 1 individual, a person will experience severe pain, which can last up to 4 hours.
10 Triatom bugs
Triatomic bugs or kiss bugs - a subfamily of bugs, numbering 130 species. Widely distributed in the tropical regions of Central and South America, some species live in Asia, Africa and Australia. Most triatom bugs feed on plants, but there are also species that feed on the blood of large animals, including humans. People are usually bitten on the lips (hence the name). These insects are dangerous in that most of them are carriers of the causative agent of Chagas disease, from which about 12,500 people die each year.
Dorylus is a genus of nomadic ants that live in central and eastern Africa, as well as in tropical Asia. The body length of working ants is from 3 mm to 13 mm. The number of one colony can reach 20 million individuals. These unusual ants are constantly moving, from one temporary nest to another, hunting at the same time for all animals encountered in the way. In Africa, they are considered one of the most widespread and dangerous predators.
The seventh place in the ranking of the most dangerous insects is occupied by wasps - all stinging insects from the order Hymenoptera, not related to bees and ants. Currently, there are many different species, but they are all divided into single and social. Got on this list because of their sting ability. After a wasp sticks a sting into a person’s skin, it injects poison, which can cause an allergic reaction and lead to death.
Locusts are a species of insect common on all continents except Antarctica. Grow from 2 to 10 centimeters in length. Every day, one locust eats the amount of plant food equal to its own weight. They are able to gather in flocks numbering several billion individuals and destroy crops of crops in large areas, thereby indirectly contribute to the onset of hunger. Africa is particularly affected by locust invasions. The noise produced by the formed "flying cloud" whose area can reach up to 1 thousand km. sq. can be mistaken for thunder.
4 Tsetse fly
Tsetse fly is a genus of diptera insects, numbering 23 species. Almost all live in tropical and subtropical Africa. The length of their body is 9-14 mm. They feed on the blood of large animals, including human. The tsetse fly bite leaves a deep and painful wound that simultaneously causes a sensation of pain and itching. A small swelling occurs at the site of the bite. The Tsetse fly is also a carrier of trypanosomes, which cause deadly diseases such as sleeping sickness and Chagas disease. Today, about 25,000 people become infected with sleeping sickness each year.
3 Africanized Bees
An Africanized bee or “killer bee” is a hybrid of an African bee with different types of bees. It was introduced in Brazil in the 1950s and mistakenly released into the wild in 1957. It quickly spread throughout South and Central America. "Killer Bees" are extremely aggressive. According to statistics, more than two hundred people died from the bites of these bees, several thousand were seriously injured. They attack any animal that appears within a radius of 5 meters from their hive. They are also able to pursue offenders for half a kilometer, and sometimes further.
Fleas are wingless blood-sucking insects that parasitize on the body of animals, birds and humans. The length of their body, depending on the species, varies from 1 to 6 mm. Widely distributed on all continents (including Antarctica). They can jump up to 18 cm vertically and up to 33 cm horizontally. Fleas directly cause two diseases in a person - pulicosis and sarcopsylosis. In addition, these disgusting parasites are carriers of many dangerous infectious diseases. It was found that fleas are capable of transmitting about 25 different diseases. These insects can also be intermediate hosts of some parasitic worms, including some nematodes.
Apis mellifera scutellata
Artificially bred bee turned out to be one of the most dangerous insects. Scientists obtained this species by crossing African and some European species of bees. Because of the strength of the poison, aggressiveness and frequent attacks on people and pets, they are called killer bees. On their account is not one human life. They live in the USA, South America, Brazil, annually mastering new territories. A sting of 1 bee will not lead to death, but an attack by a group of killer bees will leave no chance of salvation.
What can be dangerous insects for humans?
Some species of bugs, ants, bees, flies, mosquitoes and other arthropods pose a threat to humans. All dangerous insects can be divided into two groups:
- Poisonous. These are all stinging and biting species that introduce toxic substances into the victim’s body.
- Carriers of infections. By themselves, such insects are safe, but they can infect humans with one of the deadly diseases.
Top of the most dangerous - aggressive, poisonous, carnivorous - insects on the planet
Many species of insects protect themselves with poison, parasitize animals, sting and bite people to get nutrients for further reproduction. However, only a few species pose a serious danger. A collision with them can be fatal. In the top 15 deadly creatures were insects with the strongest poison, eating living flesh or exhibiting extreme aggression during an attack. A detailed description and photos of the creatures included in this list can be seen below.
Lonomy Butterfly Caterpillar
One of the most poisonous caterpillars lives in South America. This is an unusually beautiful caterpillar of the lonomia butterfly. On the body of the caterpillar there are many villi containing terrible poison. Contact with it leads to the destruction of blood cells, impaired renal function. Because of the many hemorrhages, bruising appears on the skin. Touching several of these tracks causes death.
Anopheles - carriers of malarial plasmodia
These dipteran arthropods can infect people with malaria. They carry malarial plasmodia, which multiply and parasitize in the human body. Only female mosquitoes are bloodsucking. It is they who spread malaria among people.
Anopheles - one of the most famous insects in Africa. Annually, the infection is diagnosed in 500 million inhabitants of the continent, of which about 1 million die due to lack of timely medical care. This mosquito is found all over the world, it is not only in Antarctica, however, only those living in the tropics carry malaria.
Bulldog Ants (Black and Red)
The body of a bulldog ant is similar to a hornet, its length is about 4.5 mm. A distinctive feature are the jaws, which are 2 processes longer than 0.3 mm with notches on one side. Bulldog ants use them for protection.
In addition, black and red ants have a sting. Mortality from bites of bulldog ants is 3%. After the attack, the victims develop an allergic reaction in the form of arrhythmia, headache, lowering blood pressure, edema. In severe cases, anaphylactic shock occurs.
African bee - a hybrid of an African bee with European
These insects are called killer bees. The species was bred by humans when crossing European and African bees. There are no external distinctive features of killer bees, but it has been established that they are characterized by excessive aggressiveness.
Africanized bees attack animals and people, even if they do not feel threatened by them. One individual can sting the victim several times. The aggressors are attacking in a swarm. The victim develops an allergic reaction to a large amount of poison, often anaphylactic shock and death.
Tsetse - a carrier of sleeping sickness
Speaking of the world's dangerous insects, one cannot but mention the tsetse fly. This insect lives in Africa and infects humans with deadly sleeping sickness, or trypanosomiasis. Any warm-blooded animals and people can become tsetse fly victims. The fly has a long proboscis and attacks very quickly.
The infection is manifested by swelling of the lymph nodes and limbs. Then there is a breakdown of the cells of the immune system and disruption of the central nervous system. The patient constantly feels drowsiness and severe pain, indicating the destruction of internal organs.
Kissing bug - the carrier of Chagas disease
Bed bugs got their name due to the fact that they bite the victim in the lip area. They infect people with Chagas disease. Redness occurs at the site of the bite, then other symptoms appear:
- lowering blood pressure
- difficulty breathing.
After the acute phase, chronic develops. A typical sign of the disease is an increase in the size of the colon, esophagus and ventricles of the heart. About 10 thousand people die from this disease every year.
Gadfly: human skin, subcutaneous bovine, nasopharyngeal
The most dangerous insects are the gadflies known to many. This family includes 176 species. Larvae of human skin gadfly can harm a person. These flies live in Central and South America. Females lay eggs on human skin. When the larva leaves the egg, it gnaws at itself a small passage into the subdermal space of the epidermis and is there for two months.
The nasopharyngeal gadfly is considered one of the largest flies on the planet, this insect usually affects sheep. Viviparous females inject their larvae onto the mucous membranes of the nose, eyes and mouth of animals, and sometimes humans. Larvae grow and feed on the host tissues, they penetrate the pharynx, frontal sinuses and even the eyeballs, causing esterosis.
The gadfly family also includes the carnivorous fly larva, or bot fly. Different types of this insect parasitize in the body of horses, sheep and other animals. The victim swallows the eggs of the flies while eating food. The parasite feeds on the host organs, eating passages in them. For humans, the danger is larva man bot fly.
Moth coquette lives in North America. It has an attractive appearance and does not pose a threat to humans. However, the caterpillar of this moth is not so harmless. Her body is covered with long hairs. The larva looks like a beautiful fluffy lump that you want to pick up. However, it is impossible to touch the caterpillar, since thin spikes containing poison are located under the soft hairs. Once in the bloodstream, a toxic substance causes digestive upset, damage to the lymphatic system, and respiratory failure, which leads to the death of the victim.
Bug Beetles (Melo> Bug Beetle
Scallops are a family of poisonous insects that are extremely dangerous to humans. There are about 70 types of boils, all of them use viscous mucus to protect. When danger arises, the beetles do not bite the enemy, but release liquid through the pores on the body. This mucus contains a poisonous component - cantharidin, which, upon contact with the skin, corrodes it and causes blisters and abscesses. If cantharidin gets on damaged skin, the kidneys and urinary system are disturbed. Penetration of poison into the blood can cause human death.
All annihilating termites
Termites according to modern classification are part of the cockroach squad, which includes cockroaches. In the world there are about 3 thousand types of termites, most of which are not dangerous to humans. They eat cellulose fibers, are involved in the enrichment of the soil with nutrients. In some countries they are eaten.
However, some species are considered the most dangerous pests, the attack of these small (on average - 10 mm) “relatives” of cockroaches on household buildings of people leads to their complete destruction. Food for termites is not only the body and ceilings of the house, but also all furniture, interior items that contain cellulose.
These cockroach cousins avoids being outdoors and travels through tunnels from the ground and their own excrement. If the wooden frame of the structure does not come into contact with the ground, the risk of their attack will be significantly reduced.
Mosquitoes also belong to the most dangerous insects, most often the inhabitants of Africa suffer from their bites. The mosquito's body size does not exceed 25 mm; populations of these bloodsuckers live in tropical countries. A mosquito bite can cause death. Pests transmit infections such as leishmaniasis, pappatachi fever, bartonellosis, dengue fever, yellow fever, encephalitis and malaria.
Mosquitoes are the main carriers of plasmodium. Children under the age of 5 years and expectant mothers are especially hard-hit. After a bite, the patient develops anemia due to the destruction of red blood cells. When the infection reaches the vessels of the brain, the person dies.
Fire ants (born Fire ant) are several related ants from the group of species Solenopsis saevissima species-group of the genus Solenopsis, which have a strong sting and poison, whose action is similar to a burn from a flame (hence their name). More often, the invasive Red Fire Ant, spread throughout the world, appears under this name. There are known cases of stinging a person with one ant with grave consequences, anaphylactic shock, even fatal.
Brown hermit spider
The second spider on our list, Brown Hermit, does not release neurotoxins like the Black Widow. His bite destroys the tissue and can cause damage that takes months to heal.
A bite very often goes unnoticed, but in most cases, the sensations are similar to those with a needle prick. Then, within 2-8 hours, the pain makes itself felt. Further, the situation develops depending on the amount of poison that has entered the bloodstream. The venom of a brown hermit spider has a hemolytic effect, which means that it causes necrosis and tissue destruction.A bite for young children of the elderly and sick people can be fatal.
Siafu (Dorylus). These nomadic ants mainly live in East and Central Africa, but are also found already in tropical Asia. Insects live in colonies, which can number up to 20 million individuals, all of them blind. They make their travels with the help of pheromones. The colony does not have a permanent place of residence, roaming from place to place. During the movement to feed the larvae, insects attack all invertebrate animals. Among such ants there is a special group - soldiers. It is they who can sting, for which they use their hook-shaped jaws, and the size of such individuals reaches 13 mm. The jaws of the soldiers are so strong that in some places in Africa they are even used to fix the seams. The wound may be closed for as long as 4 days. Usually after a Siafu bite, the consequences are minimal, you do not even need to call a doctor. True, it is believed that young and old people are especially sensitive to the bites of such ants, there have been deaths from complications after contact. As a result, annually, according to statistics, from 20 to 50 people die from these insects. This is facilitated by their aggressiveness, especially when defending their colony, which a person can accidentally attack.
Giant asian bumblebee
Many of us have seen bumblebees, they seem rather small, and there is no particular reason to be afraid of them. Now imagine a bumblebee that has grown, as if on steroids, or just look at the Asian giant. These hornets are the largest in the world - their length can reach 5 cm, and the wingspan is 7.5 centimeters. The length of the sting of such insects can be up to 6 mm, but neither a bee nor a wasp can compare with such a bite, and bumblebees can also bite repeatedly. You can’t find such dangerous insects in Europe or the USA, but traveling around East Asia and the mountains of Japan, you can meet them. To understand the consequences of a bite, just listen to eyewitnesses. They compare the sensations of the sting of a bumblebee with a hot nail driven into a leg. The sting venom has 8 different compounds, which cause discomfort, damaging soft tissues and creating a smell that can attract new bumblebees to the victim. People who are allergic to bees can die from the reaction, but there are cases of death due to the poison of mandorotoxin, which can be dangerous if it gets deep enough into the body. It is estimated that around 70 people die from such bites every year. Curiously, the sting is not their main hunting tool - the bumblebees of their enemies are crushed by large jaws.
Lonomia is a caterpillar of the Lonomia butterfly living in South America. It looks bright and attractive. The body of the insect is covered on all sides with green villi, which help to disguise themselves among the foliage. These villi contain the most dangerous toxin, which instantly violates blood coagulation. Touching the caterpillar can cause cerebral hemorrhage, kidney pathology. And a person who stroked several individuals at once will face death.
This is the name of the butterfly caterpillars with the beautiful name Molly Coquette. They look pretty and fluffy, but don't be fooled. This insect is by no means as harmless as it might seem. Fragile spikes are hidden among the fluffy hairs. When touched, they break off and remain in the human body, causing severe pain, burning. After a while, symptoms such as dizziness, vomiting, sharp abdominal pain, and sometimes respiratory failure join in.
One of the most dangerous varieties of this type of insect. They do not build anthills, but roam entire colonies in search of prey. Stray ants are blind and attack, feeling blood. They can completely eat a person in less than a day.
The insect lives in Africa and is a carrier of sleeping sickness. After a bite of an infected fly, the activity of the endocrine and cardiac systems is disrupted. In Uganda, over 200 thousand people have died over the past 6 years after being defeated by this fly.
Outwardly, killer bees practically do not differ from ordinary honeybees, which attack only if necessary to protect the hive. African bees attack everything that moves. The bite of one of them is non-fatal. The attack of several individuals at once will cause a severe allergic reaction and can lead to death.
Many believe that the bite of the gadfly is not a greater danger than the defeat of an ordinary bee or wasp. However, some types of insects, when touched by a person, leave eggs on the body that mature and migrate under the skin, causing an inflammatory process.
In Europe, killer insects are rare. Especially you should be wary of meeting with the listed representatives of the living world for lovers of exotic countries.
