The method of disinsection of livestock buildings, which includes processing of livestock buildings by method of directional atomising with insecticidal composition which consists of fipronil, phenol-free coal-bearing kreoline and acetone. All components are taken at a specific ratio. And during processing of livestock buildings the insecticidal composition is used as 0.005-0.2% aqueous emulsions in an amount of at least 50 ml/m 2 for processing non-absorbing surfaces — glass, tile, metal, painted surfaces, and at least 100 ml/m 2 for processing absorbing surfaces — wood, brick, plaster.

EFFECT: invention enables to develop an effective method of disinsection of livestock buildings at extending the range of action on pests.

The invention relates to the field of disinfection of livestock buildings and can be used in the field of veterinary science and animal husbandry.

Insects are widely distributed in nature. In agriculture they play an important role. A significant number of them lives near animals. There is evidence that attacks a large number of insects (mosquitoes, flies, cows reduce milk production up to 30%, and the young are not gaining weight[1, 2, 3].

The damage caused by insects, is composed mostly of veterinary and economic indicators is that they are parasites and vectors of the causative agents of many infectious and parasitic diseases [4].

The need of combating arthropods requires the development and introduction into production of new, modern means of pest control [5, 6]. Today to combat the insects studied and recommended a large number of insecticides of different preparative forms based on synthetic pyrethroids (permethrin, deltamethrin, cypermethrin, fenvalerate), neonicotinoids (Imidacloprid, thiamethoxam, acetamiprid) and others, for example, «Aqua-VIR», «Arsenal», «Bazan», «Biorin», «Delicated», «INTA-VIR», «FAS», «Fumitoks» [5; 6; 7; 8; 9]. However, the repeated use of the same drugs leads to sustainable development the particular insects to them [10; 11].

Creolin bisphenolic coal has a strong disinfectant, antiseptic, and antiparasitic action. It is used in psoroptes animals for therapeutic and preventive purposes. Used for preventive and emergency disinfection, disinsection, desecuritize, desinvasion livestock and poultry premises, equipment, inventory, equipment, animal care, refills descobriu and desbrieres. For processing infected and festering wounds, cuts, creases hoof, and is also used for the treatment of burns, grapes, purulent conjunctivitis, eczema parasitic origin.

Known insecticide and acaricide product (RF patent 2150829, 2000, terminated), which includes creolin and the active substance is a synthetic PYRETHROID (or a mixture of pyrethroids). The drug is intended for treatment of plants or animals against ectoparasites. Also known acaricidal preparation Creakin-Leptonic containing the active ingredient cypermethrin and creolin (RF patent 2105549, 1998).

However, prolonged use of drugs with kraainem, active beginning in which are pyrethroids, against insects cause of resistance in their populations [12], which requires to increase the rates of consumption of drugs and the number of treatments [13, 14]. Therefore, the use is the use of pesticides from other groups with different mechanism of action perspective.

High insecticidal activity at low concentrations, the minimum consumption rate, long residual action and other features characteristic of the substance fipronil» group phenylpyrazoles [15].

On the basis of fipronil known stuff means «Given» (patent of the Russian Federation 2181243, 2002), «Insecta-plus» (patent of the Russian Federation 2340181, 2007), insecticide and acaricide solution and concentrate insecticide and acaricide composition (patent of the Russian Federation 2384065, 2007), a drug for the treatment and prevention of arachnocampa mammalian animals (RF patent 2348398, 2007) and the method of treatment and prevention of arachno-Antimonov and animal medicine for the treatment and prevention of arachno-Antimonov mammalian animals (RF patent 2329797, 2007; RF patent 2329796, 2007). In the above-mentioned tools and methods we have not found any composition containing fipronil and creolin.

The aim of the present invention to provide an effective method of disinfection in livestock buildings in expanding the range of actions on harmful insects, including resistant to PYRETHROID tools.

The invention, in particular the method of disinfection of livestock buildings, is solved due to the fact that in the method of disinfection of livestock buildings capable of handling livestock premises directional method is ecocaildego spraying insecticidal composition, according to the invention as insecticidal composition use composition containing the solvent acetone as a base with a weak insecticidal properties, creolin bisphenolic coal, as an active substance that is effective against resistant to pyrethroids insects fipronil, in the following ratio, wt.%:

Creolin bisphenolic coal — 90,

Fipronil is an insecticide from the group of phenylpyrazoles contact and stomach action with long lasting effect. The substance is registered on the territory of the Russian Federation. It is a white, odourless powder.

Creolin bisphenolic coal has insecticidal, antiseptic, antiparasitic action. Is a mixture of coal oil, rosin, sodium Ichthyol, neonols and water. In appearance it is an oily liquid, transparent in a thin layer, with the smell kamenopoulou oil, dark brown to black-brown color. With water forms a stable emulsion with petty-white or milky gray. Produced on the territory of the Russian Federation.

According to the invention, in the processing of livestock buildings take into account the type of the workpiece and is used in acticity composition in the form of 0.005-0.2%of the current water emulsions in amounts not less than 50 ml/m 2 for processing non-absorbent surfaces (glass, tile, metal, painted surfaces and not less than 100 ml/m 2 for processing absorbent surfaces (wood, brick, stucco).

The technical result of the invention to provide an efficient method of pest control in livestock buildings in expanding the range of actions on harmful insects, including resistant to PYRETHROID tools.

The invention is carried out by the following examples.

Example 1. The preparation of the insecticidal composition

Weigh the required amount of fipronil and with constant stirring (for example, using a magnetic stirrer) was dissolved in acetone. Then connect the estimated volumes of creolin and dissolved in acetone of fipronil, continuing to stir. The mixture is poured into plastic 1-2 l carboys. The components and their ratios are presented in table 1:

To determine the residual insecticidal action means on the surfaces of the contacting insects spend the first 7 days after treatments test objects daily, and later with an interval of 6-7 days. For the experiments used flies 3-5 days of age.

From the data presented in table 4, it is seen that the composition for insecticidal action on surfaces is not inferior to the famous high-performance products. Residual insecticidal activity on his glass and wooden test objects at the level of 60-100% (depending on dose action the existing substances) remained 10-12 weeks.

Example 5. A study of the effectiveness of the proposed method of disinfection of livestock buildings

Production tests we conducted in FSUE ochos Tyumen region. Processed internal walls, Windows and entrance gates pigpen water emulsion tools using the sprayer Oleo-Mac. This took into account the type of the processed surfaces: absorbent (wood, plaster, etc. or non-absorbent (glass, metal, tiles etc), effective dosages which can vary considerably according to literature data [18] and our own studies [19]. Use the same dosages for different types of surfaces can lead to irrational consumption of the drug, so in a production environment, we used the concentration of the claimed composition CK99,5calculated on the basis of laboratory experiments for two types of surfaces: absorbent and non-absorbent.

Example 2: DM99,5for glass surfaces was 0,026 mg A.I/100 cm 2 (the upper limit 0,041), which corresponds to 0,0052% (upper limit 0,0082%) water emulsion. For convenience of preparation of working emulsions in the production conditions, these values were rounded up to 0,005-0,01%. SD99,5for wooden surfaces was 0,882 mg A.I/100 cm 2 (the upper limit 1,946), which corresponds to 0,088%(upper limit of € 0.195%) water emulsion. For convenience of preparation of working emulsions in the production conditions, these values were rounded to 0.1-0.2%.

Thus, in the production were tested 0,005-0,010% water emulsion of funds on non-absorbent surfaces (glass, painted walls, metal surfaces) and 0.1 to 0.2% emulsion of water — absorbent surfaces (brick, wood, stucco) with primary processing of non-absorbent surfaces in order to save the drug.

For counting the number of flies spent fishing during the day on sticky sheets of size 10×50 cm, located in 8 accounting spots of the room, and counted the average number of individuals per 1 m 2 surface. The number of adult insects accounted for three days prior to disinfection before and after full recovery of their number in the premises. The effectiveness of disinfection expressed in absolute numbers and in percentage. The residual effect was considered effective as long as the number of insects was reduced by 70% or more.

The number of insects in the room before treatment was 6.2 thousand individuals/m 2 after disinsection decreased to 0.56 tycooly/M. Thus, the insecticidal effectiveness of the proposed structure in production environments was 91%. Residual insecticidal activity was maintained for 14 days. Full restoration of the number of the items insects observed on the 20th day after the treatment. Thus, the problem is solved.

SUBSTANCE: device is designed so that air is sucked through the inlet opening by means of propulsion of an axial fan and is passed through the device for containing a chemical agent that contains the active ingredient for pest control, for formation of air containing this active ingredient. The air is discharged through the outlet opening for dispersing the active ingredient into the surrounding atmosphere. An inlet opening located in front of the fan, opens in its axial direction. The outlet opening located behind the fan, opens in its radial direction. An annular wall is provided surrounding the fan, and a flow channel for air providing connection between the outlet section of the fan and the outlet opening to convert air coming from an axial fan in its axial direction, into the air, moving in its radial direction.

EFFECT: air cooling device for pest control is proposed, which is preferably used as portable on the user’s body part and is highly effective in combating insect pests.

SUBSTANCE: invention relates to agriculture, in particular to biological methods of plant protection. The method to control insect pests, mainly with thrips, in vineyards with snouted mites lies in use of complexes consisting of several native and introduced species of mites (phytoseyide, ameroseyide and aceoseyide) of different trophic orientation. The complexes are produced consistently in several stages. The complex with dominated specialised snouted mites is produced in the period before flowering, and a complex of non-specialised snouted mites species — during the growth of berries.

EFFECT: invention improves the efficiency of control of insect pests of grapes, and increase the production of high quality environmentally friendly products due to expanding the spectrum of action of snouted mites and increasing the number of trophic links in ampelocoenosis.

SUBSTANCE: invention relates to the field of applied entomology, it can be used in biological research and in planning organisational and medical measures to protect humans and animals from bloodsucking mosquitoes. The device comprises an independent source of electron supply placed in the housing 1, as well as a microphone 5 with an amplifier 6, a heating system consisting of a board with heating elements 3. A gauze screen 4 is placed over the heating elements, which is saturated with attractant, such as meat juice. Control devices and the connectors for hooking up power cable and outlet are mounted on the housing with the ability to connect to the data link. A metal plate 7 with a threaded hole for mounting the unit to a tripod is placed on the housing 1.

EFFECT: invention makes enables to monitor on-line the degree of activity and aggressiveness of mosquitoes in nature or in hard-to-reach places, for example, insects in the basements of houses without direct contact with a human.

FIELD: plant protection.

SUBSTANCE: invention provides insecticide S,S’-[2-(dimethylamino)trimetylene] dibenzothiosulfonate (Bankol, Bensulban, Vicbenone, Rubane) in the form of white crystalline powder highly efficient against lepidoptera and coleoptera agricultural pests from lepidoptera and coleoptera families, in particular against Colorado beetle in potato crops. In order to obtain wettable insecticidal powders based on S,S’-[2-(dimethylamino)trimetylene] dibenzothiosulfonate and containing filling material, dispersant, and sticking agent, all components are mixed in water-soluble ketone medium at 55 to 80 о С, after which solvent is gradually distilled away. Foe example, following components are used, wt parts: S,S’-[2-(dimethylamino)trimetylene] dibenzothiosulfonate 50, carbon white 50, surfactant based on α-olefin fraction C12-C14 8-10, sodium ligninsulfonate (sticking agent) 1-25, and water-soluble ketone 50-100.

EFFECT: simplified preparation technology, reduced power and material consumption, and improved quality of insecticide due to uniform distribution thereof on carrier surface.
