Mosquitoes, or real mosquitoes, or blood-sucking mosquitoes (Latin Culicidae) are a family of dipterous insects belonging to the group of long-nosed (Nematocera), the females of adults of which are in most cases a component of the nasal complex. Characteristic for this family of oral organs: the upper and lower lips are elongated and form a case in which are placed long thin needles (2 pairs of jaws); the males of the jaw are underdeveloped - they do not bite.

Movable larvae and pupae of mosquitoes live in standing ponds. Fossil mosquitoes are known from the Cretaceous period. In the modern world, there are more than 3000 species of mosquitoes belonging to 38 genera. In Russia, there are representatives of 100 species belonging to the genus of real mosquitoes (Culex), kusak (Aedes), Culiseta, malarial mosquitoes (Anopheles), Toxorhinchites, Uranotaenia, Orthopodomyia, Coquillettidia.

A mosquito-pussy, or an ordinary mosquito (Latin Culex pipiens) is a polytypic species (otherwise - a complex) of blood-sucking mosquitoes (Culicidae). Distributed universally and has a great epidemic significance. Most mosquitoes encountered are between 3 and 7 mm in size. Females feed on plant juices (to sustain life) and blood (for the development of eggs), mostly human, and the male feeds exclusively on plant juices. .

Female mosquitoes are carriers of various human diseases, for example, Japanese encephalitis, meningitis, as well as animals such as avian malaria. The forms of the nominative subspecies of the mosquito-sulcus Culex pipiens pipiens forma pipiens and Culex pipiens pipiens forma molestus are the main objects for research in the form of

Mite

Клещ - Чей это укус?

At the attack of the tick, the body reacts with a red stain at the site of the bite.

The insect can be on the victim for a long time and grow in size, feeding on its blood.

Mites (Latin Acari) - a subclass of arthropods from the class of arachnids (Arachnida). The most numerous group in the class: more than 54 thousand species have been described, including 144 fossils. Such a heyday of ticks was achieved due to the fact that in their historical development they acquired microscopically small sizes, which enabled them to master the upper layers of the soil, rich in decaying plant remains.

Fleas

Блохи - Чей это укус?

The bites of fleas can be confused with allergies or mosquito tricks, because similar red turges appear on the skin.

But, unlike mosquitoes, these insects bite rather painfully, the bites from them are itching much stronger.

At the site of the bite of the hornet, redness and swelling of the tissues develop, blisters may appear.

A person will feel a burning pain, even more acute than with a wasp sting. Since hornets are larger than their congeners, their poison is more toxic. It has histamine and acetylcholine.

Female and male are winged, working individuals are wingless. Antennae cranked, in females and working individuals 11-12-segmented, in males 12-13-segmented, in a number of species 4-, 6- or 10-segmented. The main antennal segment (skapus) is usually much longer than the rest. The posterior chest (epinotum) represents the first segment of the abdomen that merged with the hindquarter. The abdomen itself is attached to the epinotum by a stem formed by the first or second segments. Ants of some subfamilies (myrmicins, ponerins and others) have developed a sting. Wings with reduced venation.

Slepen

The horsefly looks like a big fleshy fly.

But, unlike her, it can be quite painful to bite a person and refresh oneself with his blood.

First, at the site of the bite, you can notice a small red spot more than 1 mm in diameter.

Then there is swelling and itching.

Numerous in the forest zone, steppes and deserts, but usually keep on the banks of rivers and lakes, where larvae of many species develop. In the world fauna, about 4,400 species are described, which combine about 200 genera; on the territory of the CIS countries about 200 species. Fossil flies have been known since the Oligocene.

Louse

Вошь - Чей это укус?

If you notice small red dots similar to mosquito bites, in places where hair grows thick, on the head, neck or behind the ears - you are bitten by head or pubic lice.

If such points are on the back, abdomen, arms and legs - it's the tricks of lingerie lice.

Bites are located a few centimeters apart, and at the site of the bite, you can see the puncture of the skin.

Lice are carriers of dangerous diseases, such as trench fever and typhus.

Вошь - Чей это укус?

Lice (Latin Anoplura) - suborder of small obligate ectoparasites, a squad of fluffy (Phthiraptera). Mouth organs of lice are adapted for piercing the skin of the host animal and sucking blood. Lice are highly specialized parasites, they live only on one or some related species of animals. This feature of lice in some cases makes it possible to find out the proximity of host hosts. Lice, for example, the human louse (Pediculus humanus), are carriers of such dangerous diseases as typhus and recurrent typhus. Distributed throughout the world.

Bug

Клоп - Чей это укус?

At first glance, bug bites are similar to traces from an attack of fleas, mosquitoes or allergies.

On the skin, you can see swelling, redness, itchy.

But the "work" of bedbugs can be distinguished by the characteristic chains-paths on the skin.

The bites are close together.

And bedbugs bite more than mosquitoes.

Multiple tracks on the body can be found in the morning - on the hunt bugs leave at night.

Клоп - Чей это укус?

Bedbugs (Latin Heteroptera) - a suborder of insects from the squad of Hemiptera, previously considered as an independent unit.

About 40 thousand species from more than 50 families. In the Far East of Russia there are about 800 species (for the former USSR more than 2000 species were indicated).

Клоп - Чей это укус?

The bed bug (Latin Cimex lectularius) is a type of bedbug, a common obligate synanthropic bloodsucking insect.

It is an ectoparasite of humans and warm-blooded animals - it feeds on their blood.

Etiology

The fright caused by some insects from the order of the Hymenoptera with the help of a sting produces a poisonous liquid that forms in the special glands (see Hymenopterygia).

Mosquito bites cause itching (see Kulicidosis), as well as flea bites (see Dermatophilia).

Parasitization of lice leads to itching, dermatitis and other pathological skin manifestations (see Pediculosis, Fthyriasis).

The reaction to bug bites can occur from itching to anaphylaxis (see Hemipterosis). Also, people are bitten by mosquitoes (see Flebotodermia), flies (see Tabanidosis), midges (see Simulodotoxicosis) and other dipterans. A person can also be bitten by thrips (see Tizanopterny dermatitis).

The bites of bloodsucking insects (and mites) can lead to infection with vector-borne diseases, such as malaria, leishmaniasis.

In addition to insects, centipedes can be bitten by centipedes (see Bites of the Millipedes), spiders (see Arachnidism, Latrodectism, Loxoscelism), scorpions (see Scorpionism), saltpaws, poisonous pincers (see also Bites of Arthropods ).

Clinical picture and symptoms

There are three types of reaction to bite. The usual reaction includes the area around the bite with redness, itching and pain. Large local reactions occur when the tumor area is more than 5 cm. Systemic reactions occur when symptoms of lesions are observed in areas of the body far from the bite.

The skin reaction to insect bites usually lasts from a few hours to several days. However, in some cases, a local reaction can last up to two years. These bites are sometimes misdiagnosed as benign or cancers.

Clinical manifestations with stings of stinging insects range from minimal pain and local erythema to life-threatening anaphylactic reactions. Local reactions can vary from papules or blisters at bite points to swelling of the entire limb. The clinical signs of anaphylactic reactions associated with sensitization to stinging insects are similar to manifestations of anaphylaxis caused by other causes. The patient may experience generalized urticaria, obstruction of the upper and to a lesser extent of the lower respiratory tract and circulatory collapse.

Allergic and toxic reaction

Allergic reactions occur differently: from local symptoms to shock with a fatal outcome. There are 4 types of general reactions:

    1) Lung common reactions: urticaria, itching, malaise, fear. 2) General reactions: symptoms of type 1 include shortness of breath, abdominal pain, nausea, dizziness, vomiting. 3) Severe form of general reactions: in addition to previous manifestations, asthma, dysphagia, hoarseness, incoherence of thoughts, fear joins. 4) Shock: In addition to the above symptoms, cyanosis, falling AD, collapse, involuntary defecation, loss of consciousness.

Toxic reactions develop with the simultaneous bite of a large number of insects. Symptoms appear after a few hours in the form of edema, headache, vomiting, diarrhea, fever, seizures, numbness, coma.

Simultaneous stinging and biting of a large number of insects, such as bees, can lead to death.

Death in severe cases occurs mainly due to asphyxia with subsequent vascular collapse.
