Millions of species of insects that live today on earth play a vital role in the ecosystem of our planet. Although most of them are safe, some may deliver a person a lot of trouble, and some can be toxic and even deadly. From habitual ants and flies to more exotic beetles – offer you a list of the 25 most dangerous insects in the world.
Termites do not pose a direct threat to humans, they play an important role for the environment, moreover, in some cultures they are even used for food. But at the same time, termite babies can inflict enormous damage to the infrastructure, sometimes making houses completely unfit for housing.
Lice are wingless parasites that feed on particles of skin, blood and other secretions of the human body. Most often, the carriers of these insects are people. In nature, there are about fifteen different types of lice. Like termites, lice do not always carry a direct threat to human health, but they can be carriers of diseases.
3. Blackfoot Mite
Every year black-footed mite infects thousands of people with Lyme disease, which begins with a rash around a bite reminiscent of a bull’s eye. Early symptoms of this disease include headache and fever. With the further development of the disease, the victim 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 the tick.
4. Nomadic ants
The first creation on our list, which is dangerous in the literal meaning of this word, is wandering ants, known for their predatory aggression. Unlike other kinds of ants, stray people do not build their own permanent anthills. Instead, they create colonies that migrate from one place to another. These predators constantly move during the day, hunting for insects and small vertebrates. In fact, the entire united colony can kill in one day more than half a million insects and small animals.
Most wasps do not carry particular direct danger, but certain species, such as the German wasp of North America, are large and can be incredibly aggressive. If they feel 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.
6. The Black Widow
Although the stinger of a female black widow spider can be very dangerous for a person due to the released at the bite of neurotoxins, if the right time to provide the necessary medical care, the consequences of the bite will be limited only by some pain. Unfortunately, isolated cases of death from a black widow’s bite still met.
7. Hairy caterpillar Moles-coquette
Caterpillars Moly-coquette Megalopyge opercularis look cute and fluffy, but do not be deceived by their cartoonish appearance: they are extremely poisonous.
Usually people believe that the hairs themselves are burning, but in reality the poison is released through thorns hidden in this “wool”. Spines are extremely fragile and remain in the skin after a touch. The poison causes burning around the affected area, headache, dizziness, vomiting, severe abdominal pain, lymph node damage and sometimes stopping breathing.
Cockroach is known as a carrier of many diseases that are dangerous to humans. The main danger of living together with cockroaches is that they get into the toilet bowls, garbage cans and other places of bacteria accumulation, as a consequence – are their carriers. Cockroaches can be the cause of many diseases: from worms and dysentery to tuberculosis and typhus. Cockroaches can tolerate fungi, unicellular organisms, bacteria and viruses. And here is a funny 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 people and are the cause of insomnia, vomiting, nausea and other health problems.
10. Bed bugs
A person does not feel the bite itself, because the bug’s saliva contains an anesthetic. If the bug from the first time could not get close to the blood capillary, it can bite a person several times. At the site of the bite bite, itching starts, and a blister may also appear. Occasionally, people experience a severe allergic reaction to a bug bite. Fortunately, 70 percent of people do not feel practically no consequences from them.
Bedbugs are domestic insects and do not belong to the group of carriers of infectious diseases, but in their bodies they can persistently keep pathogens that transmit infections through the blood, for example, viral hepatitis B, as well as plague, tularemia, and Q fever. The greatest harm to people they deliver with their bites, taking away from a person a normal rest and sleep, which can subsequently negatively affect the moral health and performance.
11. The Human Gadfly
Human gadflies have larvae that can transmit life-threatening parasites to humans. Also known as torsalo, human ovids are usually transmitted by mosquitoes. When the mosquito carrying the larva of the human gadfly lands on the skin, the larva enters the body of the carrier. After a few days, it grows under the skin and can cause a serious infection if you do not immediately treat the bite site.
12. The centipede
The centipede (Scutigera coleoptrata) is an insect that is also called a flycatcher, appeared presumably in the Mediterranean. Although other sources say about Mexico. The centipede has become very common all over the world. Although the appearance of such insects is unattractive, they generally perform useful work, since they eat other insect pests and even spiders. True, with entomophobia (fear of insects) such an argument does not help. Usually people kill them because of an unpleasant appearance, although in some southern countries the centipedes are even protected.
The flytrap is a predator, they inject the victim with poison and then kill it. Often the flycatchers settle in apartments, without causing any harm to food or furniture. They adore moisture, often centipedes can be found in cellars, under baths, 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 a person, although it can be compared with a small bee sting. For some, this may 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 that an allergic reaction to the poison of an insect is possible, but this still happens very rarely.
13. The Black Scorpion
Let the scorpions do not belong to the insects, as they belong to the detachment of arthropods from the class of arachnids, but we still brought them to this list, especially as black scorpions are the most dangerous species of scorpions. Most of them live in South Africa, especially often they can be found in deserts. Black scorpions differ from other species with their thick tails and thin paws. Black scorpions sting, injecting their victim with poison, which can cause pain, cause paralysis and even the death of a person.
14. The Predator
Another bloodsucker is a predator, he is Assassin bug, he is also 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. The predator is responsible for the transfer of Chagas disease, this beetle parasite often infects people living in poor rural areas.
15. The bullet ant
Paraponera clavata is a species of large tropical ants from the genus Paraponera Smith and the subfamily Paraponerinae (Formicidae), which have a strong sting. This ant is called 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 pulsation and relentless pain within 24 hours after a bite. In some local Indian 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). During the study of the chemical composition of the poison, a paralyzing neurotoxin (peptide), called ponerotoxin, was isolated from it.
16. The Brazilian Traveling 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 Records of 2010, this type of spider was named the most poisonous spider in the world.
The poison of spiders of this genus contains a powerful neurotoxin, known as PhTx3. In deadly concentration, this neurotoxin causes loss of muscle control and breathing problems, leading to paralysis and eventually suffocation. The bite of moderate soreness, the poison causes instant infection of the lymphatic system, getting into the bloodstream in 85% of cases leads to heart failure. Patients feel a stiff rigor mortis during life, men sometimes have priapism. There is an antidote, equally used with antibiotics, but because of the seriousness of the damage to the body’s poison detoxification procedure is actually equal to the chance of surviving the victim.
17. The malarial mosquito
Malarial mosquitoes, or anopheles, are a genus of Diptera insects, many species are carriers of human parasites – malarial plasmodia. The mosquito is infected with a malarial plasmodium from a person – a patient or a carrier. The malarial plasmodium passes through the mosquito cycle of sexual reproduction. An infected mosquito becomes a source of infection for a person 4-10 days after infection and is such for 16-45 days. Mosquitoes are carriers of other types of plasmodia that cause malaria in animals.
18. Rat fleas
Rat fleas are one of the most dangerous types of fleas (Pulicidae), a carrier of plague. They are parasites of rats (Rattus, Nesokia) and gerbils (Gerbillinae). They are the carriers of the plague rod (Yersinia pestis) and Rickettsia typhi, as well as the intermediate hosts of parasitic worms of rat Hymenolepis diminuta rat and mouse Hymenolepis nana. Diseases can be transmitted from one generation to another through the eggs.
19. African honey bee
African bees (also known as bee-killers) are descendants of bees brought from Africa to Brazil in the 1950s when they try to improve honey production in this country. Some African uterus began to interbreed with local European bees. The resulting hybrids moved north and are still found in Southern California.
African bees look the same and in most cases behave like European bees that currently live in the United States. They can be detected only by DNA analysis. Their stings also do not differ from the sting of a common bee. One very important difference between the two species is the protective behavior of African bees, which manifests itself when protecting their nest. In some attacks in South America, African bees killed livestock and people. By this behavior the AMP deserved the nickname “bee-killer”.
In addition, this type of bee is known for behaving like an invader. Their swarms attack the hives of an ordinary honey bee, invading them and setting up their queen. They attack with large colonies and are ready to destroy anyone who encroaches on their uterus.
Despite the fact that the flea is usually not perceived as dangerous, fleas transmit numerous diseases between animals and humans. Throughout history, they have contributed to the spread of many diseases, such as bubonic plague.
21. Fire ants
Fire ants are several related ants from the group of 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 under this name there is an invasive red fire ant that has spread all over the world. There are cases of human stinging by an ant with severe consequences, anaphylactic shock, up to a fatal outcome.
22. Brown hermit spider
The second spider in our list, a brown hermit, does not release neurotoxins, like a black widow. His bite destroys the tissue and can cause damage, the healing of which will take months.
The bite very often goes unnoticed, but in most cases the sensations are similar to the sensations when the needle is pricked. Then within 2-8 hours the pain makes itself felt. Further, the situation develops depending on the amount of poison that has got into the blood. The poison of the brown hermit-spider is a hemolytic action, and therefore causes necrosis and destruction of tissues. Bite for young children, elderly and sick people can be fatal.
23. The ants of the Siaafu
Siafu (Dorylus) – these nomadic ants mostly live in East and Central Africa, but are also found in tropical Asia. Insects live in colonies, which can number up to 20 million individuals, all of them blind. Traveling their own they do with the help of pheromones. The colony does not have a permanent place of residence, wandering from place to place. During the movement to feed the larvae, insects attack all invertebrates.
Among these ants is a special group – soldiers. They can sting for what 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 can be closed for as long as 4 days. Usually after a Siafu bite, the consequences are minimal, it is not even necessary to call a doctor. True, it is believed that young and old people are particularly 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 protecting their colony, which a person can accidentally attack.
24. Giant Asian Bumblebee
Many of us have seen bumblebees – they seem rather small, and there is no special reason to be afraid of them. And now imagine a bumblebee that grew 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 – 7,5 centimeters. The sting length of such insects can be up to 6 mm, but with such a bite no bee or wasp can be compared, bumblebees can also sting repeatedly. Such dangerous insects in Europe or the US can not be found, but traveling through East Asia and the mountains of Japan, you can meet with them. To understand the consequences of a bite, it is enough to listen to eyewitnesses. They compare the sensations from the sting of a bumblebee with a hot nail driven into the leg.
The poison of the sting has 8 different joints that cause discomfort, damaging the 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 deaths due to a poison of mandorotoxin, which can be dangerous, getting deep enough into the body. It is estimated that about 70 people die each year from such bites. It is curious, but the sting is not the main tool for hunting bumblebees – they are crushed by their large jaws with their enemies.
25. The tsetse fly
The tsetse fly lives in tropical and subtropical Africa, having chosen the Kalahari and Sahara deserts. Flies are carriers of trypanosomiasis, which lead to the disease of animals and humans by sleeping sickness. Tsetse anatomically very similar to their usual relatives – they can be distinguished by the proboscis on the front of the head and the special manner of the addition of wings. It is the proboscis that makes it possible to extract the main food – the blood of African wild mammals. On this continent there are 21 species of such flies, which in length can reach from 9 to 14 mm.
It is not necessary to consider flies as such harmless for the person, after all they really kill people, doing it quite often. It is believed that in Africa up to 500 thousand people are infected with sleeping sickness, carried by this insect. The disease disrupts the endocrine and cardiac system. Then the nervous system is affected, causing confusion in consciousness and sleep disturbance. Fatigue is replaced by hyperactivity.
The last major epidemic was recorded in Uganda in 2008, in general the disease belongs to the list of neglected in WHO. However, in one Uganda for the past 6 years from sleeping sickness 200 thousand people died. It is believed that this disease is largely responsible for the deterioration of the economic situation in Africa. It is curious that flies attack any warm object, even a car, but they do not attack a zebra, considering it only as the flickering of bands. Tsetse flies, moreover, saved Africa from soil erosion and overgrazing caused by cattle.
The man came up with different methods of fighting these insects. In the 1930s, all wild pigs were destroyed on the west coast, but this only produced a result of 20 years. Now they are fighting by shooting wild animals, cutting down bushes and treating males with radiation to prevent them from multiplying.
