Description
argasids are carriers of many diseases, the most dangerous and widespread of which are considered a form of spirochetes and Central Asian tick spirochetosis.In addition, they can carry on yourself:
- Taiga encephalitis.
- Tularemia.
- typhus fever.
noteworthy that the disease that carries the adult, can be transferred to the larvae by inheritance.This applies mainly to infectious or parasitic diseases, penetrating directly into the egg.It is for this reason that the population of ticks is often a serious threat to the stability of the epidemiological situation.Creating so-called tank serious viruses that may arise unexpectedly almost anywhere in the world.
structure
order to take timely first aid to the bite, everyone should know how to look township mite, whose structure allows to distinguish it from the majority of blood-sucking insects.The body of the tick longitudinal or oval shape resembles an egg.Proboscis is located on the ventral side, while the dorsal shield is completely absent.Cover the trunk In argasids chitin and malogorbkovy.
gender identify individuals without specialized knowledge and appropriate tools is rather difficult, because the sexual dimorphism is very weak.In addition, the variety has received from nature the characteristic welt extending along the edges of the body and creating a visual edge on it.
Power
tick township can eat the blood of any vertebrate, regardless of age and individual characteristics.At the same time required for complete filling of the stomach, ranging from 3 minutes to an hour, it all depends on the temperature conditions in which the bite.During his stay on the body of a tick can consume the amount of blood 12 times larger than its own weight.
Always keep in mind that if you have had a tick is found on the body, you can become a direct carrier of serious diseases.Scientists found out that it was mites belonging to the family argasovye can infect you tick typhus, and the causative agent of the disease is transmitted in several ways, and transstadial transovarial.
Reproduction
bisexual reproduction enables stable reproduction that has a significant impact on the speed with which developing township tick.The cycle of development includes a gradual transformation.First of all eggs produced from the larva, which by repeated rebirths in the nymphal stage is transformed into a full-fledged argasids.
female lays eggs immediately after finishing drinking the blood.At the same time tries to choose for them the most quiet place.On average, their number at a time not more than a hundred, but for each year of her life she can lay a thousand eggs, from each of which grow in the future the new tick in need of food.
larvae
leaving a food source, mites begin to mate.Because eggs are put down tick settlement, during the month begin to emerge fully formed larvae which immediately start looking for a first food sources.Later, it was the first blood they consume, serve as a major impetus for the further development into a complete individual.At this stage of the tick size is less than 2 mm, and in color is dominated by beige or light brown.
In that case, if the temperature at the time when they will find a food source, will remain favorable, the standard development cycle is about a year, under unfavorable conditions, it can grow up to two years.The mass of the body for several days increases more than 20 times.The body is covered with small spikes tick undergoing molt as they grow older.
Later fully developed mite can not eat up to 10 years without experiencing much discomfort from forced starvation.In general, the time required to spend mite to go through all the stages of development, up to a quarter of a century.
main types and characteristics of ticks
In order to distinguish argasids from others and on time to apply the most appropriate treatment, not be amiss to know what are the other representatives of ticks, the highest prevalence among whom were:
- argasids -prefer to live indoors, the role of which perform a variety of cracks, holes and caves, as well as accommodation.
- Gamasid mites - tiny eyeless mites, which do not exceed 5 mm.The most common parasites on birds and small mammals, which is transmitted to man through a variety of different viral pathogens.
- Tiroglifi - most often found in the home.The main places that are suitable for their reproduction - is a variety of food stocks, in particular the various cereals and flour.The main problem that occurs in humans, eat food contaminated with these mites - is necrosis of the intestine.Furthermore, entering into direct contact with human skin, these mites leave on it, in most cases, rash and irritation.Some individuals may even take root in the human body or animals, causing constant discomfort.
periods of life
Village tick life cycle which in most cases is short, ranging from a few months to several years, it is a real threat, because under favorable conditions, life expectancy increased to 20-25 years.
completely being formed into an adult mite township change lumpy leather cover, but the thorns on it are completely absent.The limbs 8, the genital opening located between the first and second pair of legs on the lower torso.At the same time it represents a female gap and males hole covered with a special shield.
Bite
ticks on human or animal body is a temporary ectoparasite.In place of direct bite is usually observed the formation of a small dark red nodule with highly visible edging pale color.If time does not take action to remove the tick, then knot grows and is transformed into a papule with a characteristic hemorrhagic bleeding, the diameter of which is typically less than 8 mm.
mite settlement, making bite irritating effect on the tissue of the body, resulting in the site of the bite there is severe itching, which is the main stimulus for rapid access to medical care for most patients.
