Do you know how many species of insects live on our planet? From 2 to 4 million different types! Scientists have described about 625,000 species of insects, and there is little hope that all existing insect species will ever be described. No class of animals can even come close in terms of the number of species to insects.

If you try to estimate the absolute number of insects living on earth, then the figure will turn out to be so huge that the human mind cannot even imagine it! The only way that scientists can estimate the approximate number of insects living in the earth is to calculate their number in 1 square. m of wet soil. This number ranges from 500 to 2000.

Thus, in one acre of good soil, there should be about 4 million insects. Most of these insects are indistinguishable to the human eye. Many of them are simply microscopic in size. And only a few thousand species of insects bother a person enough to try to control them. If you think about it, you realize that a person is literally surrounded by insects, but does not suspect how many of them are around!

The vast majority of insects have two things in common: their body is divided into three parts and they usually have six legs, although there are exceptions to this rule.

What is an aphid?

Aphids (or, in other words, plant lice) are green and brownish insects no more than 6 mm in length. Aphids multiply so quickly that if they were not destroyed by natural enemies, they would have eaten almost all the plants on Earth! Aphids can be found on the leaves, stems, roots of all kinds of plants. These insects often cause significant damage to fruit trees, flowers, vegetables and crops. They have an unusually strong mouth or proboscis protruding from a tiny head. With this proboscis, the aphid pierces the surface of the leaf and sucks out its juices, after which the plant withers and, most likely, dies.

The most curious detail in the life of aphids is that the aphid's body secretes a sweet liquid called "honeydew", and ants like to drink this liquid. Ants capture aphids and take care of them like a farmer takes care of cows. Having dragged the aphids into their nest, the ants supply them with a sufficient amount of greenery and carefully protect them. When an ant wants to milk its "cow", it strokes the aphid's abdomen with its antennae, tiny drops of honeydew stand out on the edge of the abdomen. These drops are drunk by the ant. Man, on the other hand, has no particular reason to protect aphids, so he often destroys them by spraying them with chemicals.

What does a butterfly eat?

As you know, the life of a butterfly goes through several cycles. First the egg, then the caterpillar, then the chrysalis (which sleeps all winter), and finally the butterfly emerges from the chrysalis. There is one period in the life of a butterfly when it eats especially a lot. This is the time when she is a caterpillar. For some species of butterflies, the caterpillar stage is the only period of life when they eat anything at all. The caterpillar eats and grows in size until the skin bursts, which gives way to a new one, and so many times in a row, and after a few weeks the caterpillar becomes many times larger than at the beginning.

But in general, butterflies are quite adapted to eating: they have a head, chest, abdomen. Those butterflies that eat have a proboscis instead of a mouth, which is in a folded state between meals, like a clock spring. This proboscis can penetrate deep into the heart of a flower in order to suck out its nectar.

In moths, this proboscis can reach a length of 15–20 cm, so that it is able to penetrate large tubular flowers. Some of them have incisor-like teeth at the end of their proboscis, with which she can gnaw through the peel of fruits and drink their juice!

What do flies eat?

Due to their tiny size (1000 adult flies weigh 25–30 g), the common housefly does not need much food and will therefore find enough food for itself anywhere. House flies don't eat solid food because they have nothing to chew on. The mouth of a fly is adapted only for the absorption of liquid food. The role of the "language" is performed by a proboscis resembling an elephant's trunk. It is also divided in two at the end, and these channels act as tubes through which liquid food is sucked.

The common belief that house flies bite before a thunderstorm is incorrect. It's just that in these cases, house flies are confused with other types of flies, such as desert flies or dung flies. These flies are blood-sucking, they bite people. But, if house flies don't bite, then why are they considered so dangerous to humans? The fact is that the paws with pads and the body of the flies are covered with protruding hairs, and sticky mucus envelops their tongue. This means that dust and dirt constantly stick to the fly. And since house flies look for food everywhere, including garbage and sewage, there may be bacteria in the dirt and dust that stick to the fly, causing various diseases, which switch to our food when a fly lands on it, and together with food enter the human body.

How are flies born?

Everyone knows that flies are carriers of infection. The fly is born and spends most of its life near garbage and other places favorable for the development of bacteria. In fact, this damp, decaying matter is the most optimal breeding ground for flies. Here the female lays white eggs (about 1.2 mm in size), from which thin, worm-like, legless larvae emerge. This is the "feeding" stage of the fly's life. Five or six days later, the skin of the larva thickens and turns brownish and the fly's life enters a resting stage: the larva becomes a chrysalis.

After another 5–6 days, an adult fly emerges from the pupal shell. The size of this fly does not change in the future: large flies do not grow out of small ones. Another 10 days later, the fly mates, and a little later the female lays 100 to 150 eggs! Not all types of flies breed like houseflies.

Some hatch eggs in themselves and give birth to live larvae, and some species lay eggs that are already in the pupal stage. Due to the fact that flies carry diseases, a person is constantly fighting them. It is best to kill flies in winter or in early spring. During this cold season, the flies hide in dark, warm corners and are very hungry all the time, so they are easy to catch and kill.

How many insects are on our earth

Insects are the most numerous group of organisms on Earth. In fact, there are about 8 million species of insects (what science knows today). It is estimated that there may be up to 30 million species of insects on the planet. Thousands of new species are discovered every year.

Approximately 80% of insect species are herbivorous, 15% are predators, 5% are bloodsuckers and corpse-eaters.

In total, there are supposedly 9.8 billion (10 ^ 18) billion insects on Earth. Insects are so numerous on Earth that for every person living on Earth, there are approximately 1.4 billion insects (!) This is 6 times more than fungi (1.5 million) and 36 times more than plants ( 250,000).

Behind these numbers lies a subtle reality: some species of insects are endangered. This could be disastrous, especially for agriculture.

Probably to some ears it will sound like a joke “Castrostrophic consequences for agriculture”, because farmers spend a huge amount of effort and insecticides on the fight against “harmful insects”, dreaming of the day when there will not be a single insect left on the earth.

No one realizes how important insects are in the food chain and in the balance of our ecosystems.

Here, for example, is the great Kalosoma (beetle), Calosoma sycophanta- a great pine lover: this beetle destroys up to 200-300 caterpillars in the summer, and also eats silkworm larvae and cocoons. He perfectly climbs trunks and thin branches, hunting for caterpillars. Unlike most ground beetles, it flies well. Voici, voilà.

In addition, insects are natural pollinators of plants. The day the insects are gone, farmers will realize the importance of insects. I'm willing to bet that the big phytosanitary companies have already planned to sell drones and robotic plants to replace insects.

Insects of the blood-sucking type feed mainly on human blood, therefore they are able to infect the human body with serious and very dangerous diseases and infections. What kinds of insects exist? What are the names? Consider in this article.

1. The basis of nutrition for female mosquitoes is the juice of some plants, as well as human blood (for their eggs), while male mosquitoes use only plant juice as food, so only females attack humans. The life time of a female mosquito is 43–47 days, depending on the ambient air temperature and the type of feeding of the insect, males live only 19 days. The habitat of an individual is damp territories and swampy areas.
2. With all this, female mosquitoes can bring great harm to a person - they can transmit diseases such as malaria, meningitis, yellow fever, Japanese encephalitis and many other varieties of diseases.

Fleas

The life span of a flea can reach several months. The habitat of the insect is considered to be carpets, baseboards, basements. As well as soft toys, where an individual can safely and comfortably breed and raise their offspring.

Fleas can transmit to humans many infectious and rather serious diseases: hepatitis, plague, brucellosis, encephalitis, anthrax and much more.

Lice

Major pests and carriers of harmful diseases

This detachment of insects easily harms both human habitation and health.

cockroaches. Fast insects originating from the order of cockroaches. The length of the body of an insect reaches a mark of 1.7 - 9.5 centimeters. Plant and animal residues, various garbage, and, in some cases, feces are considered the main food of an insect.

The color of cockroaches is mostly yellow-brown or black. The life of a cockroach is about 30 weeks, and some individuals are able to live for about one month. Basements, trash cans, human dwellings and dining rooms are considered the main habitat of cockroaches. Cockroaches cause the main damage to surrounding furniture, food, and book bindings.

Cockroaches are capable of spreading helminths, as well as various infectious diseases.

house ants

Small insects from the Hymenoptera family. They are active in everyday life and mostly live close to humans. The body length varies from 2 to 4 millimeters. House ants can eat anything that gets in their way, but most of all they like to use meat products, fish and sweets. The body color of ants is mainly yellow or brown. Individuals live only in large groups, sometimes the number of individuals in one such group reaches a million.

The lifespan of ants is represented by the following numbers: males about 20 days; and worker ants, as well as females - about two months; the queen female lives about 275 days. Habitat - human dwelling, trade enterprises and buildings of public and fast food. Ants cause the main harm to plants, products, and also carry a large number of microbes and bacteria.

Two-tailed

Insect type - arthropods, detachment - six-legged hidden jawed. Insect lifestyle predominantly secretive and nocturnal. The body length of the two-tail is 2-3 centimeters. Insect nutrition consists of microscopic insects, as well as living microscopic organisms. Body color red-brown. The life expectancy of an insect is one year, they mainly live inside damp rooms (kitchen, bath and other similar rooms). In humans, insects cause particular disdain and dislike only for their appearance, also the insect spoils the plants, surrounding furniture and can bite painfully.

Woodlouse

Woodlouse- This is an arthropod insect that comes from the order of isopods, and the suborder of crustaceans. The lifestyle is mostly hidden (insects prefer to hide under trees or stones) in damp areas. The total size of the insect is 20 millimeters. Lives approximately 9-12 months. The basis of nutrition are living and decaying plant species. The coloration is gray and the belly is white. Woodlice do not carry any particular harm to humans and do not tolerate any harmful infections.

Carpet kozheed

This beetle comes from the order Coleoptera, from the family of kozheedov. Lives mainly in rooms, houses and apartments, and in wild nature lives in hollows of trees or nests. The length of the body varies from 2.5 to 5.5 millimeters. Most often, the insect eats organic residues left after dust in the home.

Fur coat moth from the detachment lepidoptera butterflies . The length of the body varies from 5 to 8 millimeters. Leads a predominantly nocturnal lifestyle. Body color is golden brown. Lives mainly from 200 to 250 days. The fur coat moth lives in the nests of pigeons or in human apartments. This insect is capable of spoiling products made from materials such as wool, felt.

Clothes moth

Lepidoptera type insect presented in the form of a butterfly. The color of the insect is straw yellow. The length of the body is 5-9 millimeters. Life expectancy reaches an average of 8 to 10 days, in warehouse premises, as well as in ordinary apartments. Actively spoil things made of wool, fur, cotton. Destroy soft upholstery furniture, carpets, which causes great damage.

Midge

The midge is considered an insect that bites quite painfully, and also carries diseases such as leprosy, glanders, plague, tularemia and anthrax.

Harvest spiders

Small creatures from the spider family. The body length ranges from 2 to 10 millimeters, while the insect has very long legs, reaching up to 9 centimeters. The color of the body is grey-brown. They are active only at night. It loves to live inside dark and damp places, but in human habitation it lives in warm, dry places near windows. It eats small insects and flies, thereby bringing special help to people. They can live up to 12 months. In their body they contain poisonous substances, they use it only to kill their prey, which accidentally fell into the web. After the killing process, the spiders begin to eat their prey.

flies

Flies carry only one harm to humans: they can bite painfully, carry numerous bacteria, microorganisms, and dirt, which can often lead to the development of infectious diseases.

silverfish

A small creature that has no wings squad - bristletail. Body length varies from 0.8 to 1.9 centimeters. The color of the insect has a silver tint. Activity occurs only at night. They like to settle in places with high humidity (in most cases they can be found in baths, saunas, baths). They are omnivores. They do not cause serious harm or danger, and are also not able to transmit any infection to the person himself.
