Steppe tolstun endangered species of grasshoppers

In the Black Sea steppe zone, among toots and grasses, there is a steppe steppe. It is a rare species of grasshoppers that is endangered. Large massive insects before the beginning of the 20th century. met in the south of Russia and Ukraine, in the foothills of the Caucasus. The economic activities of people and plowing virgin steppes led to widespread extinction of the species. Surviving individuals live in pristine protected areas of the steppe, the number of such places is constantly decreasing. Tolstun steppe fell into the European Red List and the Red Book of Russia.

Description of the species

Tolstun steppe or multi-hump-headed (Bradyporusmultituberculatus) representative of a family of true grasshoppers from the order of the Orthoptera. The endemic species of the Black Sea has become an extremely rare inhabitant of the steppe fauna. The body of insects is of unusual round shape, the length of the male is 50-80 mm, the female is 40-60 mm. The length of the saber-like ovipositor of the female is 14-22 mm. The upper part of the body of the grasshopper is bronze-black, the yellow-brown spots merge on the abdomen into two longitudinal bands. There are individuals with spotted and one-color body color.

Legs are walking, on the shins are large spines and powerful spurs. The head is spherical, the eyes are well developed. Oral apparatus of gnawing type. Antennae long, setiform, situated below the eyes. The large pronotum has two keels along the sides and four longitudinal convex ribs at the top. The insect has no wings, rudimentary elytra are hidden under the pronotum. The Orthoptera detachment is characterized by a considerable thickening of the hips of the hind legs. The bald man has weak limbs, he can not make jumps for a long distance.

Interesting fact. Small elytra perform the function of an audible apparatus – with their help the grasshoppers produce chirping sounds. It is noteworthy that Bradyporusmultituberculatus females also have a stridulatory apparatus, although in other species it is found exclusively in males.

In the photo it can be seen that the body of the steppe thick man is securely protected by strong covers with tubercles. This feature was the reason for the appearance of the name “multi-humpbacked globules”, which was given to the insect by the Russian naturalist Grigory Fisher von Waldheim.

Studies conducted in the second half of the XIX century, speak of the spread to the Voronezh region in the north, to the Caucasus in the south and the Volga to the east. After 100 years, the range has decreased noticeably, in many places insects have died out. The habitat of the steppe thick man in the Rostov region, Nevinnomyssk (Stavropol), the Krasnodar Territory and Kabardino-Balkaria has been confirmed. Grasshoppers settle among motley grass and sod-cereal vegetation.

Insects prefer areas with rugged terrain, where ravines alternate with flat areas. They settle in a dense thicket of herbs and bushes, they enter the floodplain meadows. Males divide the territory among themselves, the neighboring sections are located at a distance of 30-50 cm from each other. From dusk until late at night, climbing on branches of a bush or a tall grass, they loudly chirk. Insects do not like heat, activity is manifested in the morning and evening hours.

Imago and their offspring herbivores, in the diet cereals and legumes, sage, plantain, dandelion, buckwheat. Tolstuny do not hunt, but replenish the stores of protein, eating soft tissues of dead grasshoppers.

Reproduction

The period of mating is in June. In sharkheaded grasshoppers, the number of males and females is approximately the same. The males are attracted by the sound of chattering. Pairing insects occurs several times. Two weeks after fertilization, the female proceeds to laying. With its saber-like ovipositor, it makes holes in the soil or turf. Eggs are deposited in portions of 6-8 pieces. Winged-wingers differ incomplete transformation, they do not have a pupa stage.

Mating of tolstones

The total fecundity of the female is 50-70 eggs. In natural conditions for the development of the embryo is characterized by diapause for 3 years, in conditions of captivity – 5 years. The larva appears in May to become an adult insect. She needs 5 moults. In the middle of June, the imago and larvae of the last age are neighbors.

Information. A long diapause explains the periodic increase in the population of multi-hooligan tolstuns.

Security measures

In the XIX century. Steppe steppes flourished throughout the steppe and forest-steppe zone of Russia and Ukraine. Active economic activity has led to a critical reduction, and in some cases, to the complete destruction of the grasshopper population. Among the limiting factors:

  • development and plowing of virgin lands;
  • widespread haymaking;
  • grazing;
  • use in the fields of insecticides.

The extinction of the species required the adoption of strict protective measures. Grasshopper Bradyporusmultituberculatus is listed in the Red Book of Russia and several regions – Rostov, Stavropol, Voronezh. It belongs to the I category – the threat of extinction. The insect is protected in Ukraine, entered on the European Red List.

In 2014, in the Kabardino-Balkaria Republic, a mass appearance of the Tolstoy was recorded. It is seen on the Tersky Range, where the landscape and turf-cereal vegetation create optimal conditions for the existence of the species. Dryness of the climate and mountainous terrain have become natural limits of economic activity. The find makes it possible to re-qualify the steppe steppe from the category in III – a species common in a restricted area.

As protection measures for the preservation of the relic species, it is necessary to organize islets of virgin lands with mixed grass. Natural natural areas will become a haven for endangered insects. In such areas it is necessary to prohibit grass mowing, cutting of shrubs, grazing. In nearby fields, the use of insecticides is limited.

Sinanthropic insects: cockroaches, ants, bugs are uninvited guests in a human dwelling. Assortment of funds from household pests regularly updated with new names. One of the most effective modern drugs is Get from cockroaches, as well as other flying and creeping insects. Insecticide is used in the professional disinsection of premises. Its composition is safe for humans and warm-blooded animals. The special technology of using chlorpyrifos microcapsules allows to completely destroy a colony of domestic insects.

Structure of the preparation

The active substance of the preparation is 5% chlorpyrifos. This is an insecticide belonging to the class of organophosphorus compounds. It has been used to fight insects for about 20 years. During this time the substance proved itself as a reliable means of a wide spectrum of action. The compound retains the poisonous effect for a long time. In the company Get products a unique technology is applied – the active insecticide is placed in polymer capsules. Chlorpyrifos is located under the shell of a capsule of microscopic size.

Nano capsule with insecticide

Information. In the Get vial, there are billions of nano capsules with an insecticide.

The microcapsules are in an aqueous medium, the stabilizers make the composition homogeneous. Chlorpyrifos belongs to the second class of danger for humans, the use of an insecticide under the polymer coating reduces the level of toxicity for humans.

Mechanism of action

Insecticide is able to penetrate into the body of red and black cockroaches in three ways:

  • through the respiratory organs;
  • together with eaten food;
  • through the covers of the body.

The preparation in the form of an aqueous solution of the suspension is applied to various surfaces. Upon contact with them, the insect clings to the feet of hundreds of invisible capsules with a toxic substance. Upon contact with water, the granules are activated. After a while, chlorpyrifos begins to leak onto the surface of the shell. During this period the cockroaches manage to bring the insecticide into their nest and infect the relatives.

Microcapsules on the legs of cockroaches

Getting into the body of an insect, the compound causes tremors, spasm and paralysis. They refuse all life support systems and death occurs. The use of capsules provides a prolonged action of the Get agent. The period of its activity is up to 180 days. The drug is effective in combating a large number of domestic pests:
