Description

 The invention relates to means for catching and destroying cockroaches, in particular to cockroach traps using adhesive surfaces, and methods for their manufacture.

 A device for catching harmful insects is known, comprising a closed cavity with a base, a lid and entrances, provided with surface areas inside covered with a sticky substance, and a device for attaching a bait in the form of a needle fixed to a base on which a set of interchangeable nozzles is installed in series: for sticky substance , insulating rings, for bait - ferromone or stern bait. This device is quite inconvenient when used in everyday life, because when replacing a nozzle with an adhesive layer filled with fixed insects, a nozzle with a fresh adhesive layer should be dismantled and reassembled.

 Known adhesive trap for capturing insects, rodents, etc., in particular cockroaches, designed to be installed in the corners of the premises and consisting of a package with side openings containing an attractant - ferromone isolated from cockroach culture Blatella germanica, a layer of non-drying adhesive on the base, surrounded by the perimeter of a strip of "slippery" surface, having a coefficient of friction that is lower compared with the adhesive, and hindering the release of insects that are not sufficiently stuck in the adhesive layer.

 The closest is the glue trap device, comprising a housing with side openings, an insect trap made in the form of an adhesive surface from a layer of entomological glue and placed on the base of the housing, and an attractant source located on the insect trap. The invention provides for making holes of a certain configuration (in the form of an inverted triangle with fixed angles) and at a certain height of the side walls of the trap, preventing the possible departure of cockroaches that are stuck in the adhesive surface only with their forelimbs (since their hind limbs have significant force that allows them to release the forelimbs and , in principle, be saved). The nature of the attractant source used is not disclosed.

 A known method of manufacturing a trap for cockroaches, including placing on the base of the insect trap made laminated from superimposed layers of a substrate of a polymeric material — foamed urea resins, polyethylene, styrene, adhesive — entomological glue and a temporary protective coating that is removed when using the trap, as well as placing an attractant source on an insect trap after removing a temporary protective coating from it.

 In the known method, the adhesive can either be applied on a substrate in advance — a layer of polymer material — and duplicated by a temporary protective coating, or the adhesive may be contained in a tube and spread onto the substrate immediately before use. As necessary, the filled insect trap can be exchanged for another, fresh one. In a known manner receive traps reusable. However, when using such traps, which have a special configuration of the holes on the walls of the housing, in the gaseous and dusty rooms, the holes become dirty and the traps cease to act effectively.

 The technical result to which the invention is directed is the creation of effective and cheap traps of one-time action and the expansion of the range of attractive sources.

 To achieve the specified technical result in a known device containing a housing with side openings, an insect trap in the form of an adhesive surface from an entomological adhesive layer placed on the base of the body, and an attractant source located on the insect trap, the attractant source is a cardboard saturated with flavoring substances with the smell of pome seeds fruits and crustaceans or smoked fish products.

Preferably, the technical result is achieved if the adhesive surface is made of an entomological adhesive layer with a thickness of 50 - 230 μm, and the ratio of the mass of flavoring substances and the area of the insect trap is in the range 1: 60 - 75 mg / mm ² .

 To achieve the specified technical result in a known method, comprising placing on the base of an insect trap body laminated from superimposed layers of a substrate of a polymeric material, entomological adhesive and a temporary protective coating, and placing an attractant source on the insect trap after removing the temporary protective coating from it, a layer of entomological glue is made with a thickness of 50 - 230 μm, a polyethylene terephthalate film is used as the polymer substrate material the back side of which is pre-coated with acrylate glue and siliconized paper, while the attractant source is made of cardboard impregnated with a flavoring substance with the smells of pome fruits and crustaceans or smoked fish products, and the insect trap is fixed by glueing it on the base of the case after removing siliconized from the substrate paper.

 In FIG. 1 shows an assembled trap according to the invention, and FIG. 2 - disassembled (cardboard die cutting). Cardboard die cutting has a central part 1, which serves as the base of the trap, and two sides 2, the central part is designed to accommodate an insect trap 3 and an attractant source 4. On the sides 2 there is a slot 5 designed to fasten the sides 2 by means of the protrusions 6, and the slot 7 folding valves 8, ensuring the penetration of insects. The notches 9 are intended to facilitate the crawling of cockroaches inward. The dotted lines 10 indicate the fold lines along which the house is folded.

 Preparation of an attractant source is as follows. On cardboard plates measuring 35 x 22 x 2.75 mm, a solution of flavoring additives imitating the smell of pome fruits and crustaceans or smoked fish products in an amount of 200 - 250 mg is applied. To ensure the safety of the smell, the attractant source is sealed in a heat-sealable film prior to use. The effect of the attractant source is checked on a laboratory insect culture of cockroaches Blatella germanica in a pan of 1500 x 2000 x 200 mm in size, the upper edges of which are smeared with liquid paraffin. The attractant source is placed on an insect trap, both in the center and with an offset from the center. Flavor additives Quince (samples 1,2), Crab (samples 3,4) and their mixture (samples 5,6) are used as an attractant in the samples. The test results are shown in table 1 (table. 1 and 2 see at the end of the description). An insect trap with a cardboard plate without an attractant source was used as a base object.

 They experience the effect of the degree of attractance, defined as the ratio of the mass of the attractant used to the surface of the insect trap, on the number of trapped insects. A set of cardboard plates impregnated with a different amount of attractant is prepared and placed on an insect trap surface of 100 x 150 mm in size. The test results are shown in table 2.

 The thickness of the entomological adhesive layer varies in the range from 30 to 300 microns. The test results of insect traps with different thicknesses of the entomological adhesive layer carried out according to the above procedure are shown in FIG. 3. The graph of the dependence of the number of cockroaches caught in two days on the thickness of the layer of entomological glue shows that the optimum thickness is 50 - 230 microns.

 The insect trap operates as follows.

 The trap folded along the dashed lines and assembled in the shape of a house is placed in the places where cockroaches accumulate. Attracted by the smell of the attractant, insects crawl into the holes, fall into the trap on the sticky surface of the insect trap and are fixed. Filling the surface of the insect trap indicates the need to replace the trap. The design of the outer surface of the trap is made in the form of a toy house.

 To implement the method, an insect trap is made as follows: entomological glue in the form of a melt is pumped from the bath to the surface of a moving tape of a polyethylene terephthalate film, on the back of which a layer of acrylate glue coated with siliconized paper is preliminarily applied. The rollers are crimped to the required thickness of the entomological adhesive layer and duplicated with a temporary protective coating. The resulting film laminated insect trap is wound onto a roll. The roll is cut into cards. A layer of siliconized paper is removed from the obtained cards, and the card with the exposed adhesive side is glued to the marking of the base of the cardboard die cutting (Fig. 2). When using the trap, the temporary protective coating layer is removed, an attractant source extracted from the sealed package is placed on the insect trap, and the cardboard die-cut is folded in the form of a house along dashed lines 10, fixing the protrusions 6 into the slots 5 and unbending the valves 8 cut along the lines 7.

Example
On the surface of the tape of a polyethylene terephthalate film with a thickness of 24 μm (on the reverse side of which a layer of acrylate adhesive with a thickness of 80 μm pre-coated with siliconized paper with a thickness of 100 μm is preliminarily applied), moving at a speed of 10 m / min, the melt of entomological adhesive is pumped from the bath at a temperature of 150 ^o C . Then, the tape is compressed with a layer of entomological glue applied to a thickness of 200 microns and duplicated by a temporary protective coating - a layer of siliconized lavsan 100 microns thick. The resulting film laminated insect trap is wound into a roll, which is then cut into 150 x 100 μm cards. A layer of siliconized paper is removed from the obtained cards, and the card is glued with the adhesive side to the central part of the housing base.
