The structure of the flour tick on the stage of a semi-natural individual

Brief certificate

• The tick of the flour is an animal with a size of 0.32-0.67 mm. Still, able to adapt to any conditions and temperatures. It survives even with radioactive irradiation.
• Decomposes not only cereals, but also flour, flax and sunflower seeds. This is its main food. In addition, in the "diet" dried fruits, crushed cereals, flour products and meat products. Do not be broat and padal.
• The main habitat, from where a flour tick appears, large columns of grain and flour - barns, warehouses. They fall there with rodents bringing ticks on their wool in the granaries. We are entered by the wind together with dust, in water, on our clothes and shoes, if there was contact with infected products, flour.
• Remains of unlocked forage, straw, cattle pens, rotting sweeping in the forests - all this favorable environment for the development of flour ticks.
• If the tick is entered into habitat familiar to it (temperature 21 ° C - 27 ° C with minimal humidity of 65%), it starts to multiply intensively. His population can be so numerous that infected culture (flour, grain) comes in motion.

For your information. The destructive parameters for the "thermo-loving" tick is the temperature below -5 ° C or above + 55 ° C, humidity: 15% and below (or above 80%).

Life cycle

Stages of life cycle:

• egg;
• larva;
• nymph;
• adult special (imago).

Eggs of oval shape of 0.1 mm in size in the body of females are launched a couple of days, after which it postponed them. After 4 days, the larva appears. It does not look like an adult person. Size - 0.12 mm. In total, 120-150 eggs is postponed for the life cycle.

Turning to the nymphs stage, the person has underdeveloped species, the oral organ is missing. Such a state can reach long, up to the onset of favorable development conditions. After that, the development is activated, the larva becomes imago. If it is comfortable, then in a week you can observe a semi-cold clus. Female larger male. The sizes of the body in it - 0.32-0.66 mm. While the male is only 0.3 - 0.43 m. By producing fertilization, it dies. Life period of females - 2-3 months.

If the habitat of the flour tick is in granaries, in barns, you need:

• Drop the room temperature to -4 ° C and below. Grain constantly turn, organize drafts. Homemade cereals take out on the frost or put in the refrigeration chamber.
• On large areas, carry out irrigation of products insecticidal and acaricidal drugs of a fumigation and contact method for disinfection: "Fostoxin", "Fosthek", "Children-EX" and others.

Preventive work on the prevention of tick penetration is reduced to the following:

• capacities for the transportation of flour and grain are clean;
• before backing up raw materials, the barn should be disinfected by treating lime, then dry well, ventilate;
• rubbish, scattered grain or flour immediately assemble and burn;
• during the storage of grain, maintain the required microclimate parameters by organizing periodic ventilation;
• the territory near the granaries, the barn, the mucolous workshop should be clean, without trash can, dumps of branches;
• prevention of grain condition is needed: temperature, humidity, presence of chitinic scales;
• take measures not allowing bird penetration into rooms with grain,

Homemade flour reserves to buy in small portions as needed, periodically view. If a malievable "live" mass is seen, such a product is destroyed.

• On kitchen shelves should be dry and warm.
• Products brought from the store are shrinking into a clean dried hermetically closing container. At the same time, you do not need to shove the reserves brought from the store to stored residues.
• Combating measures can be rejugating. Bay leaf, garlic clove or stainless steel spoon, laid on a closed capacity to products, scare the flour tick.
• It is necessary to monitor the cleanliness, control the presence of rodents. If they are detected, they can take pictures.
• It is forbidden to use expired products for food.
• Conduct wet cleaning of premises and surfaces with a weak bit of bite (on 2 parts of the water add 1 part of the fluid).
• Suspicious products to withstand at temperatures above + 50 degrees. Cereals, seeds, groan grain in the oven.
• Fighting a flour tick will be more efficient if you store dry animal feed and food in different places.

Along with flies and other pests, plants can cause significant damage to vegetable cultures. It is dangerous for planting and larvae of ticks in a garden, declared on the leaves or stalks of plants and literally emitting them to flesh.

Pest ticks usually have a piercing rotter. The most common in our latitudes are fruit and worst pings - with their photo and the description you can read on this page. We also tell me about measures to combat strawberry ticks, how to get rid of sputum ticks and other pests of plants.

Pest web tick: insect photo and how to get rid of a spider tick

The web tick is the pest relating to the sucking group. These insects make great harm to cucumbers in greenhouses and small-sized film shelters.

Look at the photo of the web tick: the body of the insect is greenish-yellow, has an oval shape. Winter females are mostly orange-red. Winter ticks under lumps of soil or in plant residues. Harbor plants tick begins to apply in spring with dry and warm weather. The maximum activity of the tick falls on the second half of July (in a protected ground) or for July-August (when cultivating cultures in open soil). For the growing season, the web tick is able to give up to 10 generations.

This pest is very voracious. Ticks live on the underside of the leaves, tired by their fine cobwebs. Damaged leaves of vegetable crops are covered with light dots, over time they become completely spotted, and then yellow and dry. On plants affected by a bypass tick, usually fall flowers and wounds, and with severe damage the plant can die. If the weather is hot and dry, spider ticks can damage the plants of the open soil.

Before fighting with a spider tick, you need to carry out preventive measures. To do this, it should be processed with an infusion of onions or garlic husks, which are prepared as follows: 200 g of husk or green mass of onions or garlic insist for 4-5 days in 10 liters of water. To protect the pumpkin crops from the spider tick in the fall, all plant residues should be destroyed and deeply populate the soil on the garden plot.

Strawberry tick, combating measures and pest photos

Strawberry tick, damaging strawberry leaves, is a very fine insect (0.2-0.3 mm) light yellow. It is possible to consider it only with a magnifying glass.

The photo of the strawberry tick, presented above, are made with a multiple increase.

Early spring ticks settle on growing young leaves and puts eggs. After 15 days, larvae are born that feed on, sucking juices of young leaves. The leaves begin to shrore, acquire a yellowish-oily shade, and with a large number of ticks even dry. The bushes strawberries lag behind in growth, berry ticks become small.

Plants affected by the strawberry tick reduce the yield of more than half. Strawberry ticks are particularly quickly multiplied in wet weather.

If seedlings of strawberries were purchased in the store, it is necessary to carry out thermal disinfection of the planting material. For this, the entire seedlings for 15 minutes it is necessary to dip in the water with a temperature of 45 ° C. Also, the spread of this pest is hampered by a rarefied planting of plants, at which the distance between the rows should be 60-70 cm, and the distance between the plants in the row is 30-35 cm.

With a strong reproduction of the strawberry tick, a two-time spraying of the landings of the decoction of tomatoes tops is recommended. It is prepared from the plants dried since the autumn. For this, 1 kg of tops are poured 10 liters of warm water, insist 3-4 hours, then boil 2-3 hours. The finished decoction is filtered and diluted with water, increasing the volume by 2 times. It is recommended to add 40 g of household soap to the tool. A finished preparation spray strawberries.

Carbofos can be applied from chemicals: 100 g per 10 liters of water, the temperature of the solution should be 30 ° C. Spraying is recommended immediately after the last collection of berries.

To combat strawberry tick treatment, it is also possible to carry out the infusion of dandelion. For its preparation, it is necessary to grind 700-800 g of fresh leaves, pour 10 liters of warm water, insist 3-4 hours, sculpting 2-3 times, then strain and immediately treat strawberries.

If the strawberries are largely damaged by the strawberry tick, after the last harvest collection and carbophos processing of the plant must be rigged. It should be done no later than the first decade of August, so that the bushes managed to form a good crown of the leaves before winter and were able to turn normally.

Garlic mite and the fight against insect pest

Garlic tick (aceraiya) amazes the plants of the family of Lily, feeding with juice of leaves. Wintering acera in bulbs. Plant shoots that were infected with this insect pest are strongly deformed, lagging behind in growth, jerked with a loop and become whitish shade.

The bulbs should carefully examine the lesion with garlic tick. If the infected bulb falls into the storage, where the temperature and humidity are not regulated, the insect begins to actively multiply. If the warehouse is increased humidity, the harness of the tick increases significantly.

When landing onions and garlic, vegetables should be carefully examined for damage to pest. Sick bulbs should be rebeling and destroyed. It should be removed only in dry weather, then you need to warm the bulbs at a temperature of 35-40 s for 5-8 days.

Plant residues, as well as patients and pest affected by the pest need to be destroyed. After harvesting, the area is drunk, adding a small amount of ash and haired lime into the soil.

Before laying plants, the family of lyrable them are shrinking with dry chalk at the rate of 20 g per 1 kg of vegetables.

Root (onion) tick and how to get rid of the bulb root tick

The root (onion) tick is mainly damaging the bulbs during storage, but can cause damage and young plants. Nasomkomi penetrates the bulbs and feeds on his scales, causing dip. If the bulbs are badly damaged by the tick, they begin to dry out.

The body of a bulky root tick of brown color, an oval shape with a length of about 1 mm. The propagation of the tick contributes to the relative humidity of the air above 60% and the air temperature is 25-28 ° C.

The larvae of the root (onion) tick outwardly looks like adult individuals, but unlike them have 3 pairs of paws.

Adults are preserved on plant residues and in the soil where the pest is entered together with infected landing material.

In order to get rid of the bulbous root tick and in order to prevent 1.5-2 months before the disembarkation, dry layer should be carried out at a temperature of 40 ° C for 16 hours or at 35 ° C for 5 days. When pest detected in storage facilities, it should be disinfected with sulfur gas or como gray. In addition, the soil should be regularly loosen, observe the crop rotation and use only a healthy planting material.

The appearance on the leaves of the garden strawberries of brown necrotic spots, wrinkles and a yellowish shade speaks about the presence of PhyTonemus Pallidus - strawberry tick. This is a dangerous pest of culture. It is able to inflict the berry of great harm and dramatically reduce its yield. To prevent this, you need to get acquainted with how to deal with the strawberry tick.

About pest

The danger representing the strawberry tick is incommensurable with its microscope. This is an exceptionally small pest, which is impossible to see the unarmed look.

He postponing his offspring on young, not yet blossomed leaves of the plant. The larvae ripen very quickly - for 15-20 days. The same period is needed for the final ripening and transformation into an adult tick.

The abilities of the meager pest are large enough. In the spring it strikes overwhelming plants, and at the end of August - the kidney of the future harvest. The most likelihood of harm arises age-related plantations.

Pests are distinguished by big fertility. During the summer period, they are excreted from five to seven generations. If the struggle with the strawberry tick is not conducted, their number increases 100-150 times. In August, there is a reproduction peak, in October they are becoming much less. With a decrease in temperature to + 10 ° C, the tick hides in the folds of the leaves for wintering.

It is necessary to carry out the processing of plantations from the tick after harvesting. This will make it possible to prevent the harmful impact of the pest on young spring shoots.

Causes of appearance

The mass lesion of the strawberry sites is caused in most cases inexperienced gardeners. The lack of elementary knowledge of compliance with the rules of crop rotation, plant care leads to deplorable results. Among the main factors contributing to the appearance of a pest should be noted:

• the presence of dampness, coolness and shaded places;
• lack of timely elimination of weeds;
• increased humidity;
• violation of the permissible density of plantations;
• abundant spread of mustache;
• the immediate proximity of the arrangement of old berry plantations;
• poor-quality planting material.

And the landing material itself often becomes the reason for the appearance of a tick on the plot. In the future, it extends through the tools, as well as through the mustache. Does not tolerate direct sunlight, but loves humidity and heat. This explains their localization in young, not yet deployed leaves. The appearance on mature leaves, mustaches and berries themselves are not excluded.

Signs of appearance

Determine that the strawberry tick began on the site, it is possible by plants. Bushes becomes much smaller compared to the past season. The full size of the leaves is observed only in some plants. In addition to a sharp decrease in the crop, the following symptoms of the lesion by tick are noted:

• wrinkled sheet plates;
• weakly developed rosettes of bushes;
• yellow leaves;
• the presence of a white plaque on the back of the sheet;
• underdeveloped and dried berries, leaves, flowers.

Damaged strawberries can give at first full berries, but gradually the plant begins to fall behind in growth. Sick leaves twisted and disappear. Flowers and already formed berries dry out. This leads to the extinction of bushes in the summer and autumn period, as well as to massive freezing in the winter.

Methods of struggle

Chemical method

The use of chemical preparations in most cases guarantees a successful way to pest. For example, good results are achieved if the prophylactic goal is to spray strawberries in the fall of carbofos.

This is a pesticide with moderate toxicity. It is widely used against all sort of pests, successfully fights with the strawberry tick.

To achieve the desired result, the spraying of the plantation should be carried out immediately after the preparation of the working mixture, taking into account the instructions in which it is recommended:

• produce processing into mad and dry weather;
• use morning or evening hours for work;
• perform spraying at a temperature not lower than + 18 ° C;
• do not process bushes during flowering period;
• the drug is applied on both sides of the leaves.

Over the season, you need to perform 2 spraying.

No less efficient use of sulfur colloid. A good result is achieved subject to the temperature of the temperature regime (from + 20 ° C to + 30 ° C). The importance of this requirement is explained by the fact that below + 20 ° C does not act on the pest, and above 30 ° C - the risk of leaves burns.

The drugs are considered to be fairly effective, distinguished by low toxicity, and Marolax, the main disadvantage of which is in the multi-rise processing.

The strawberry tick on the strawberry is not destroyed completely even when processing with chemicals, which is explained by the localization of the pest in inaccessible places. For use on personal plantations, such drugs from the strawberry tick, like Fufanon, Kemifos, Aktellik, are still recommended.

The chemical method requires great caution and is used in the case of the mass spread of the tick. Harvesting is possible only a month after the use of chemicals.

Biological method

During bulk flowering, the berries uses tick - Neoseiulus Cucumeris (Neosayulus Cubmeris). The method is good because it is possible to apply it even in the period of ripening strawberries and harvest. The greatest efficiency is achieved if the tick is produced after complete mowing of bushes and the appearance of young leaves.

Among the non-aggressive drugs are very popular at the gardeners use phytodeterm due to low toxicity. In addition, there is no possibility of accumulating funds in the soil and plants. Used with success in open soil and greenhouses.

Thermal method

Strawberry treatment in the fall is suitable for seedlings, which causes suspicion about the presence of strawberry and strawberry pests. Young bushes are immersed first in hot (+ 40-50 ° C), then in cold (+ 15-18 ° C) water. A procedure is carried out in the second decade of August, when new beds are laid.

Spring treatment of hot water. After careful cleaning of the plantation, the bushes of plants are poured with water heated to 70 ° C. After drying, they must be rich and dip.

Folk ways

Some gardeners are recommended to fight ticks using a film. When the harvest is assembled, the strawberries are covered with a polyethylene film, under which the temperature is created above 50 ° C. Pests die, and the leaves and mustache are removed under the root. After that, it should be a garden.

No less effective spraying with fus husks, garlic. Cooking infusion: 150-200 g of garlic or bows crushing, pour 10 liters of water. To withstand 10 hours, strain and spray plants.

Similarly, treatment is carried out with an infusion of dandelion leaves.

It should be remembered that it is necessary to start fighting the strawberry ticks before planting a new seedlings into the ground. In the future, constant processing are needed in the form of spraying, cutting leaves, removal of patients, loosening, feeding.

The web tick is an animal that belongs to the type of arthropod, the class of the spider, the subclass of the tick, the supercount of acariform ticks, the detachment of thrombidiform ticks, the Tetranychoidea. This article describes the Battle Tick Family (they are true web ticks) (Lat. Tetranychidae).

The first reliable information about the web ticks appeared in the XVI-XVII centuries, and their scientific description made by Karl Linnem, known from the XVIII century. Females, larvae and nymphs of most types of tetranofee are isolated by a web. With her, they protect their offspring, protect themselves from predators, blowing winds, fluctuations in temperatures, high humidity and dust. A web also helps them settle on the territory remote from the place of birth.

Weather tick - description and photo. What does a web tick look like?

Colenetic ticks are tiny herbivorous arthropods ranging from 0.2 to 1 mm. They are well developed by sexual dimorphism: males are much less females, and their body has a more elongated form.

Adults have a solid structure, without segmentation. Their body is only conditionally divided into sections, and the traces of the former dismemberment are preserved in the arrangement of Hett (bristles). The varied in the form of the silent goes with correct transverse rows: dark, bladder, shoulder, spinal, lumbays, sacrings and tailings. The bristles of web ticks can be needle, cetheless or leaf shape. They perform the touch function.

The body of the web ticks is covered with a thin structured cuticle, which can be compacted: in this case, it forms shields. Covers often form tubercles, folds or points. The color of the body ticks can be pale or greenish-yellow with dark spots (translucent internal organs) on the dorsal side. Known views with bright scarlet pigmentation. Closer to winter adult females become orange or red. Battle tick larvae - holders of 6 legs and bodies of yellow-green painting. Namif and adult spider-shaped 8 legs.

Thin legs of the spider-shaped ends with a complex claw fixture, with which the ticks cling to the leaves. On the abdominal side of the ticks there is a sexual apparatus. In females, it is represented by concave, covered with cuticular fold. The males have a copulatory organ located on the back of the body.

The rice apparatus of a piercing-sucking type. The mouth of the web ticks, the helicers, are adapted for piercing the peel of plants and suction juice. The main segments Helizer have grown, and they are two modified segments in the form of retractable stallers. The pawless iron of the tongs is located on the head side inside the intersecting short segment of the pedipalp. Tetraniowd has two pairs of simple red eyes reacting to the short-wave part of the spectrum. They are located on the second from the head conventional body segment. Stigma (holes) Fucks open at the founding Helizer.

What do the web ticks eat?

Cellite ticks are powered by vegetable cellular juice. Their salivary glands allocate an enzyme that destroys the chloroplasts of plant cells. Most often, animals will settle on deciduous trees or herbs, but there are also fans of coniferous flora. Some types of spider ticks (polyphagi) can eat hundreds of different plants, others (oligophages) have a limited set of preferred plants, and monophages are encountered, drinking juice only one representative of the plant flora. Particularly suffer from mass reproduction of cute cotton ticks, soda, bumbish, ornamental plants of open soil, greenhouses and indoor crops.

Where is the web tick in nature live?

Cellite ticks live everywhere, with the exception of Antarctica. More than 100 species of these animals were found in Russia. The boundaries of the habitat of the Tetraniowe family is limited only by an average annual temperature of 4.5 ° C. With outbreaks of breeding and shortage of power, migrates migrate in search of fresh leaves of plants. At the same time, they accumulate at the edges of the leaves, forming mechanical tangles with rapidly moving individuals. In open places in the settlement, the wind helps them.

As a rule, the web ticks love dry and warm weather. With increasing humidity, they are experiencing depression. Arthropods are not able to remove excess water coming with food, as a result of which physiological starvation occurs and intensive reproduction is stopped.

Reproduction and development of web ticks

The fertility of the tick depends on the climate, the time of year, from the food value of the plant on which they were, from the age of females and many others. Especially active web ticks multiply in dry weather at temperatures above 25 ° C. In tropical latitudes and greenhouses, their reproduction occurs continuously during the year. These spidensome can give up to 20 generations for 12 months. In a moderate climate, the offspring of the web ticks appears once a year, with a favorable weather, this number increases.

Fertilization in pawless ticks is not like the remaining acariform species: it is internal and passes without laying spermators (capsules filled with seed liquid). There is also a virgin development (without the participation of genital cells of the male). Only males with a single (haploid) set of chromosomes come out of non-advocked eggs.

The cycle of development of web ticks consists of the following phases:

1. Egg

The egg tick is a circular, translucent, with a diameter of 1 mm. On average, a day of females are postponed by 7 eggs with a stalk to attach them to a sheet or a web. In the summer in a temperate climate, they put eggs on the lower surface of the leaves, and the future of the offspring in the cracks of the bark or in the fallen leaves hide for the winter. Thus, at the stage of eggs, the web mites can well worry the winter.

1. Hemisphere-like larva

The larva of the web tick is like a lifestyle on an adult person, but in contrast to 6 legs.

1. Protonimfa

It is somewhat more larvae, with 4 pairs of legs and colorful characteristic.

1. Deuteronimfa

This stage is traced only in females. The males are the same Nymph Study.

1. Adult tickLichwood (Necknowledge)

Necknowledge is a phenomenon in which the achievement of half-produce and ending ontogenesis occurs in the early stages of development, for example, at the stage of the larvae.

Adult cobwebs are 10-20 days after the egg appearance. At all stages, except the larger, they have 8 legs.

Life expectancy of a paustic tick

In the warm period of the year, web ticks live from 2 to 4 weeks. The life expectancy of females wintering in the range reaches several months.

How to winter cobwebs?

With the beginning of a leaf fall and a decrease in the duration of the daylight to 16 hours, many fertilized females of the web ticks go into the soil and winter there, falling into the range. The range is a way to experience an unfavorable period with ticks and insects. At this time, animals slow down all the processes of vital activity. They are almost not moving, consume 5.2 times less oxygen and do not eat anything. Since they spend little energy, substances stored by them in the middle intestine epitheliums spend very slowly. During the range, the animal body acquires resistance to temperature differences, excess and disadvantage of moisture, to the effects of poisons.

With a light day until 14 o'clock, only winter female ticks are developing. In winter, they can carry a decrease in temperatures up to -28 degrees Celsius. Wintering types of spider mites are dying at a temperature of -9 ° C, while summer females die already at 0 °. In the spring, when the air temperature reaches + 12 + 14 ° C, the females of the pawless ticks come out, settled on the bottom of the leaves of the plants, soaring their web and lay eggs. The first spring generations are developing at weaning plants - nettle, swan, plantain, etc. By the middle of the summer, the web ticks move to cultivated plants and continue to develop on them.

Types of web ticks, titles and photos

Below is a description of some varieties of web ticks.

• - Widely distributed and extremely multi-dimensional appearance. He lives at all continents, except Antarctica. It is powered by hundreds of sterns, grassy and rustic plants. Not noticed only on coniferous trees. The ordinary web tick is the pest of berries, grapes, bone, fruit, grain, legumes, ornamental and indoor crops. Sowing intensively in July-August. The size of the cage tick depends on how much it eats food. Females reach length from 0.4 to 0.6 mm, males - from 0.3 to 0.45 mm. On the body of the tick, containing the first pair of legs, there are 2 pairs of simple eyes.

Adults are greenish-gray ticks, dark green or yellow, with a convex top and flat bottom surface of the body. They populate the lower part of the sheet plates, covering them with a thick layer of the cobwebs. We live ordinary web ticks with colonies. The female under favorable conditions for three weeks there is more than 100 greenish-transparent eggs of spherical shape. For the year, animals can leave 8 to 18 generations. By time, the mongles of the eggs of the pawkin tick become pearls. Tick \u200b\u200blarvae transparent, light green or greenish brown shades with two dark spots on the sides. Three weeks young goes away from the egg to an adult individual, during this time new generations appear, which are superimposed on each other. In the colony at the same time there are ordinary web ticks at all stages of development: eggs, larvae, nymphs, hawk females and males.

In the second half of summer, in conditions of moderate climate in the colonies, fertilized females preparing for wintering appear. They acquire orange-red, cease to eat and go into the soil or under the detached bark, leaving the trail from the web on the way. They are inhabited by tightly in tight groups, in sheet puff and soil. In the southern areas, ordinary web ticks multiply constantly and do not fall into hibernation, bringing up to 20 generations per year.

The ordinary web tick is especially harmful to cotton, soy, cucumbers, but getting from him and other gardening, garden and melting cultures. He loves apple trees, currants, strawberries, gooseberries and all bone. On the leaves of cotton, crimson-red spots are formed, they are abundantly covered with a web, and over time, the leaves completely change the color and fall. The bud buds are also falling out, which significantly reduces the crop of cotton. Such a picture in Central Asia is called "Canals", Urgamchak, and in the Transcaucasia, refer to "Chor".

• Atlantic web tick (lat. TetRanychus Atlanticus) The structure is close to ordinary and lives in Russia, Bulgaria, Turkey, Yugoslavia, USA, Japan. Damages cotton, clover, alfalfa, strawberries, apple tree, pear. His adults are distinguished by yellow-green body. The pest is settled on shoots, fruits, branches, on the upper and lower parts of the leaf of palm trees, citrus. Atlantic web ticks tolerant to high humidity can multiply and develop in such conditions. Their length varies from 0.3 to 0, 45 mm.
• Loves to live on many indoor plants. This is a frequent guest on callahs, balsamines, lemons, cycroes, roses, passic and orchids. Purple and scarlet females are larger than red males, their length reaches 0.5 mm. The size of males is 0.3 mm. Animals do not tolerate moisture and prefer heat.

The pending eggs of red sputum ticks are reddish, shiny, attached to the sheet or web. As they develop, they are muttered, through translucent shells begin to see the red dots - the eyes of the embryo. Before the molting eggs become opalovoid. Of these, the six-legged larvae hatch. First, they feed, and then freeze in the form of chrysalides, from which Nymph I - Protonimf hatred. It also feeds and then frozen in the form of nymphrisalides I. With a molten from her, Nymph II - deuteronimf is coming out. After the power period, it goes to nymphrisalide II, from which an adult female or male leaves.

• - The usual inhabitant of Germany and Austria. It is also found in other European countries and the Middle East. Detected in Tajikistan, Kazakhstan, Uzbekistan, Russia (in Primorsky Krai), Moldova, Romania, Czech Republic, Slovakia, Poland, Bulgaria, Italy, Spain, Portugal, France, Sweden, Switzerland, Japan, Kitai, Korea, Ukraine, etc.

Hawthorn tick lives on roses: plum, ally, hawthorn, rowan, apricot, Irge, apple tree, etc. The leaves of fruit trees are first covered with yellow spots, and then fall. Fruits on damaged shoots grow smaller than usual. Harvest losses can reach 40%, especially in dry years.

The females of this type of dark-red ticks with white legs and white ratosome, their length is 0.5-0.6 mm. The lifespan of females is about 3 weeks, during which the animals are laying up to 100 eggs on the surface of the leaves, covering them with a web. They winter under the bark of trees.

• Fiscal web tinger (lat. Oligonychus afrasiaticus) Prefers heat and dryness, therefore it lives in the tropical regions of our planet: in North Africa, Iran and Saudi Arabia. It feeds on the juice of melons, eggplants, palm trees, various cereals. From May to September, he lives on palm trees, mud and garden crops, for during this period their fruits are very juicy. During the rest of the time the palm tight breeds and feeds on cereals (on Bermuda grass, sugar cane, sorghum).

Pale-green females reach a length of 0.3 mm. In favorable conditions, animals give up to 10-12 generations per year. In the summer of females live 2-3 weeks, in winter - several months.

• Turkestan cobweb tick (lat.Tetranychus. turkestani.) - Wide polyphag, damages a variety of plants of both open and closed soil. A typical habitat of this paw-tick is Uzbekistan. But pest was found in 25 other countries on 207 types of feed plants. The Turkestan web tick is found in Japan, North America, in Europe, in the Caucasus, Middle East, Central Asia, Russia. Most often, he settles on such plants like: Abutilon (cannotte) of the theofora, cuffs ordinary, acacia, cotton, sunflower, alfalfa, ruptum ordinary, field basin, swan, melon, sowing cucumber, watermelon, nut pumpkin, russian, ip, Hop ordinary, Iva Belaya, reed, plum, gear, clover, eggplant, corn, grapes, elm.

Complete top and bottom Egg-shaped tick body 0.3-0.6 mm long, colorless and covered with soft cuticle. Greenish color appears in the Turkestan Custom Tick because it eats the cell juice of plants with chlorophyll. Spots on his body are translucent residues of digestible foods through the covers.

Winter females have red. The cold period of the year is carried out under fallen leaves, withstanding the temperature of -25 ° C, but dilded at -29 ° C. In the summer of females of Turkestan spider ticks live on average 30 days, as much as possible - up to 80 days. They postpone 3-20 eggs per day, and in total, they are obtained at least 400. From fertilized eggs, both males and females appear, from parthenogenetic - only males.

• - Cosmopolitan, which dwells everywhere. Attacks more than 200 economically important plants for humans, including various cereals, onions, garlic, asparagus, strawberries, cucumbers, spices, clover and other legumes. Sens the pest and on the room plants. Purpose only with leaves, which are covered with yellow spots, and prematurely fall out. Mass reproduction of these solo-likes is possible in dry and hot weather. Petrobia Multi-digretic are carriers of a barley tobacco mosaic virus. The virus also infects wheat.

The tick is a red-brown or black body with a length of 0.5 mm with yellow legs, the front of which is much longer than the rest. During the growing season, he brings up to 3 generations of MELO. In the fall, the female puts on the soil of the eggs that will winter.

What plants do not like a web tick?

Symptoms of a spider tick on plants

The web tick is harmful to the plant, piercing the cells of the parenchymal photosynthesising fabric and damaging chloroplasts. The reaction to such an invasion of plants may differ slightly. Signs of defeat by a bypass tick look like this:

Where does the cobweb tick on the plants come from?

The female of the pawless tick and the eggs pending the winter in the soil and under the bark of trees. In the spring, they populate nearby suitable weeds, and later cultural plants.

The web tick is an animal, which means it has the ability to actively move. Even if he behaves a sedentary lifestyle, sooner or later the food ends at its old place, and it is started in search of a new place of residence. Ceborate ticks travel on their webs with wind, slowly quarreled for minor distances.

How does the cobweb tick appear in the apartment? On indoor and greenhouse plants we enter the pest with new seedlings, soil, with things. Cellite ticks can get to the apartment and independently: through open windows of windows, descending from the upper floors or closely arranged trees.

Prevention of the web tick

If we comply with some precautions, you can prevent the appearance of a pest. Nevertheless, home plants are much easier to protect the tick from the attack, in the open soil it is harder.

When buying new plant species, they need to hold them some time separately (in quarantine), traced for their safety.

Window sills, tables, shelves and kashpo, which come into contact or are in close proximity to the bedroom plants, you need to wipe with alcohol or another disinfectant.

Soil mixture for planting crops must be disinfected. It can be shedding it several times with boiling water, rolling in the oven, disappear on the stove or water bath.

It is necessary to maintain high air humidity. To implement this task, you can purchase aurator or constantly spray plants from the spray gun.

In the garden and gardens you need to remove all weeds, pump the soil in the fall, removing the remains of cultures, and comply with other rules of agrotechnology.

In the greenhouse you need to establish a climatic mode in which pests do not live: humidity 80-90%, temperature up to 25 degrees.

As prophylaxis, plants can be processed by acaricidal drugs, as well as planting a number of flowers on which web ticks will never be treated.

Is the web tick for a person dangerous?

This spider-like brings only indirect harm to man. It does not bite it, does not infect diseases, but destroys plants planted to them. At the same time, crouchs can reach catastrophic sizes. Cellite ticks contribute to the resettlement of the spore of the gray rot, viruses, affecting the flora, thereby inflicting an additional damage to harvest.

How to deal with a paustic tick on indoor and garden plants?

You can get rid of the spider tick in different ways. Below are the effective options for the destruction of this pest.

Destruction of a paustic tick mechanical way

If one plant is hit, you need to isolate it from others or remove only damaged organs. At the initial stage of infection, it is possible to manually remove the web ticks from the leaves or wash them off with soapy water. Pliers do not like excessive water, which means to get rid of them will help water procedures and increase humidity level up to 80-90%. For this, the plant needs to be dipped in warm water or well spray from the pulverizer, not forgetting about the bottom side of the leaves, and put for 2-3 days in a transparent plastic bag, securing it over the pot from the earth.

Biological means from a web tick

• The use of natural enemies, which are afraid of spider ticks

In addition to the phytosayuseulyus paouth ticks, amblyseuses are destroyed (Lat. Amblyseius), Methaseyulus Western (lat. (Metaseiulus occidentalis), ladybugs (lat. Coccinellidae), etc.

• Biological preparations

Today, active drugs have been the greatest popularity to combat a spider tick, produced using strains and bodies of Bacillus Thuringiensis bacteria. They are safe for humans, plants, warm-blooded animals, birds and useful insects. Domestic drugs manufactured on the basis of this soil bacterium are called Entobakterin, dendrobacillin, biothel, phytodeterm, batchibacillin. Foreign analogues - Triphodermin, Bicol and others. By the way, these funds also help in combating various caterpillars who eat plant leaves.

Folk remedies for the fight with the paw

Fruit plants should not be treated with chemicals. If, during this period, they are repulsed by a web tick, you can apply effective folk remedies that are easy to make at home:

1. 2-4% solution of economic or green soap.
2. infusion of some plants - garlic, red pepper, onions, horseradish, daisies of medicinal, alder gray, dandelion of medicinal, black, black, tobacco, sorrel horse, cyclameman, orange peel, potato tops and others.

Below are several recipes:

• Recipe for vegetable informs of garlic or bow

Half a teaspoon of chopped garlic or a complete spoonful of a finely chopped onion pour a glass of boiling water, close and withstand the day. To bring a pawite tick with room colors, this infusion needs to be sprayed or wash the plant several times.

• Infusion of Gorky Pepper

100 grams of pepper pods to cut and boil in the 1st liter of water for an hour. Close and hold the day. Profilge and clog in bottles with tightly prolonged traffic jams. For the processing of indoor or garden plants from the spider tongs, 8 grams of the branch, liter of water and 4 g of the cooler household soap are mixed. This mixture spray or misses the affected plants.

• Tobacco decoction

200 grams of tobacco or mackets are poured with 5 liters of cold water and withstand during the day. Then they boil 2 hours and filter. The infusion is diluted with water in the ratio of 1: 1 and add to it 50 g. Of the economic soap in the calculation of 5 liters of fluid. This solution needs to be treated with indoor plants from a pawite tick.

• Infusion of potato tops

For 4 hours, insist 250 g of tops in 1 liter of water. A plant infected with a spider tick must be sprayed with this decoction.

Most of their braves in composition are similar to chemical preparations and are not harmless to human health. During their use, you need to take all precautions to avoid poisoning and allergies.

Chemical preparations from a paustic tick

It is possible to save the garden from the spider tick using a group of chemicals called acaricides, although other class pesticides also have a wide range of action and help to cure plants.

We give examples of some well-known means.

• Nitrafen - The drug with the smell of carbolic acid. It consists of alkylphenols produced from the resin. It helps to remove the web ticks and their eggs. Also destroys Tlya, ticks, worms, shield, leaflet, etc. Currently, the agent is rarely used, as it is able to remain in the soil for a long time.
• Carbofos. (Malation) - thick light brown liquid with a sharp smell, well soluble in water. Refers to insekto-acaricidal pesticides. Kills larvae and adult web ticks. To get rid of eggs, it is necessary to produce several treatments in a row. The drug also treats plants from Tli, medalers, weevils, garden moths, whiteflinking, etc. At the moment, the drug is ousted by more efficient and safe pyrethroids, nononicotinoids and diazine. Carbofos is toxic for bees, bumblebees, OS and other useful insects-pollinators.
• Akardan - Delivered against all stages of the paw-tick. It consists of 2 active substances - caravan and Celtan.
• Antio - Phosphorian drug. Protects plants within 12-15 days.
• Apollo- Acaricide, killing eggs and larvae. Safe for people and insects.
• Benzophosphate - Substance of contact action. It is used to combat paouth ticks on garden and garden crops. Guards plants from pests up to the month.
• Tedion. - Specific acaricide, effective against tick larvae.

Agrotechnical measures to combat a web tick

• Deep plowing

To destroy the wintering stages of the web tick, deep plowing fields are carried out. In the gardens they jump up the land next to the fruit bushes, on the beds, near berry shrubs. This technique contributes to the activation of predatory insects - stafilinide, grip, and others that can be closed in the soil and destroy their victims there (ticks, including). The positive impact of plowing on the limitation of malicious species is also in the fact that the paustic ticks located in the surface layer of the soil will die from low temperatures in winter (-29 ° C).

• Disinfection of soil

To get rid of the spider tick in greenhouses and greenhouses, in the spring, the soil is disinfection with chlorine lime or sulfur checkers.

• Distance between Grokes

If last year there were cases of plant infection in open soil, it is desirable to leave a considerable distance between the beds: it is more convenient to fight the paw-tick in one place, not allowing the spread of the pest.

• Crop rotation

• Landing stable varieties

Currently, all cultures have varieties and hybrids, tolerant or resistant to individual pests.

• Weeding

In the workplace open soil, you need to remove all weeds, so that there are no place to multiply in the early spring females of the pawn ticks.

• Thoughtful fertilization

On the soils, where nitrogen prevails over potassium and phosphorus, the number of sputum ticks increases 3 times. Conversely, if phosphoric-potassium fertilizers prevail, then the pest reproduction rate is limited.

How to get rid of the web tongs by physical methods

The physical methods of combating a spider tick are based on the destructive effects of high or low temperatures on the pest: in the fall, the soil in the greenhouse is closed with a film, fed under her hoses and drink hot steam. Also, plants are treated with ultraviolet lamps: the radiation is adversely acting on a paw-tick and helps to withdraw it.

• Of the eggs of most types of ticks, including web, there is a larva with six legs, but soon it turns into the octopus nymph. Adult spider-shaped also has 8 legs.
• Unlike the true spider tick, the false web tick (lat. Tenuipalpidae) does not break the cobwebs. Its dimensions are 0.25-0.3 mm, so it is difficult to see it with a naked eye. If his colony has become noticeable, it means that the defeat has reached catastrophic sizes.
• Scientists have discovered the types of tetrannyhoid ticks (from the Tetranychoidea's supersaturation), among which the males were not discovered. They only have females and parthenogenesis, female individuals are born. It means that the assumption that the males appear exclusively from non-advocked eggs is incorrectly.
• Usually, the springs of the males are frozen waiting for the hatching of the female and immediately begin kopulation with them. Sometimes with the appearance of a new male representative, males fight among themselves. At the same time, they take an aggressive posture: the forelimbs raise high up and push the robust styles. They put on the enemy, trying to prick it with styles or bristles of the front legs, at the ends of which drops of liquid are distinguished.
