Description

Technical Field

[0001] The present invention relates to a crawling pest attractant, a method for attracting crawling pests, and a crawling pest trap. More specifically, the present invention relates to a crawling pest attractant for attracting crawling pests such as mites, a method for attracting crawling pests, and a crawling pest trap.

Background Art

[0002] In recent years, in a living environment with increased airtightness, the problem is that mites are likely to breed. Since mites are considered the main cause of atopic dermatitis, asthma, allergic diseases, etc., the general public desires means and methods for reliably and safely controlling mites.

[0003] For controlling mites, there is a method of using chemicals such as insecticides and repellents. However, this method does not actively reduce the number of mites, and there is a problem that the dead bodies of mites remain. In addition, since people sensitive to chemicals are concerned about the effects of the chemicals, there is a demand for means and methods that can control mites easily without using chemicals as much as possible.

[0004] Therefore, in controlling mites, a type of product (mite sheet) that attracts and captures mites instead of killing or repelling them has been developed. In such a mite sheet, the attractant is important because it affects the capture performance.

[0005] Regarding attractants, it is known that a mite attracting composition containing one or more compounds selected from linear fatty acids having 4 to 18 carbon atoms as an active ingredient exhibits a mite attracting effect (see, for example, Patent Document 1).

[0006] Also, a mite attractant containing a linear fatty acid having 6 to 18 carbon atoms and at least one of a fermented food or a microorganism that ferments food is known (see, for example, Patent Document 2).

Embodiments for Carrying Out the Invention

[0028] Hereinafter, the crawling pest attractant, the crawling pest attracting method, and the crawling pest trap of the present invention will be described in detail. However, the present invention is not intended to be limited to the configurations described in the embodiments described below.

[0029] [Crawling pest attractant] One embodiment of the present invention is a crawling pest attractant containing a fatty acid having 5 to 18 carbon atoms and a plant component and / or an animal component.

[0030] The fatty acid used in the crawling pest attractant of the present invention is a fatty acid having 5 to 18 carbon atoms. When the fatty acid is used alone, it has a certain attracting effect on crawling pests such as mites. However, by combining it with the plant component and / or the animal component described below, a synergistically better attracting effect can be achieved.

[0031] Although the fatty acids having 5 to 18 carbon atoms are not particularly limited, in terms of shape, either straight-chain fatty acids or fatty acids having a branched chain may be used, and in terms of molecular structure, either saturated fatty acids or unsaturated fatty acids may be used. For example, as straight-chain saturated fatty acids, valeric acid (5 carbon atoms), caproic acid (6 carbon atoms), enanthic acid (7 carbon atoms), caprylic acid (8 carbon atoms), pelargonic acid (9 carbon atoms), capric acid (10 carbon atoms), lauric acid (12 carbon atoms), myristic acid (14 carbon atoms), pentadecanoic acid (15 carbon atoms), palmitic acid (16 carbon atoms), margaric acid (17 carbon atoms), and stearic acid (18 carbon atoms) can be mentioned. As saturated fatty acids having a branched chain, octylic acid (8 carbon atoms), isostearic acid (18 carbon atoms), etc. can be mentioned.

[0052] The crawling pest attracting method of the present invention is implemented by appropriately installing the crawling pest attractant at any place where crawling pests such as mites are desired to be attracted as described above. From the viewpoints of usability and capture of the attracted crawling pests such as mites, it is preferable that the crawling pest attracting method of the present invention is implemented by installing a mite capturing device or a crawling pest capturing device such as a cockroach capturing device containing the crawling pest attractant at any place where crawling pests such as mites are desired to be attracted.

[0053] [Crawling Pest Capturing Device] One embodiment of the present invention is a crawling pest capturing device including a crawling pest attractant containing a fatty acid having 5 to 18 carbon atoms and a plant component and / or an animal component, and an adhesive capturing part.

[0054] The crawling pest attractant in the present invention is as described in the above "Crawling Pest Attractant".

[0055] The crawling pest trap only needs to have at least a crawling pest attractant and an adhesive capture part with adhesiveness on its surface, and there are no particular restrictions on the arrangement of the crawling pest attractant and the adhesive capture part in the crawling pest trap. Examples will be described below. For example, in the crawling pest trap, the crawling pest attractant and the adhesive capture part can be arranged to be in contact with each other. Further, a composite can be formed by combining the crawling pest attractant and a base material, and in the crawling pest trap, the composite can be arranged to be in contact with the adhesive capture part (that is, at least one of the crawling pest attractant and the base material is in contact with the adhesive capture part). Also, in the crawling pest trap, the crawling pest attractant and / or the composite can be mixed and arranged with a part or the whole of the adhesive capture part. Alternatively, in the crawling pest trap, the crawling pest attractant and / or the composite can be arranged near the adhesive capture part without contacting the adhesive capture part. Furthermore, in the crawling pest trap, the crawling pest attractant and the adhesive capture part can be arranged in a part of the crawling pest trap, at multiple locations, or throughout the whole.

[0056] The base material is not particularly limited as long as it can hold the crawling pest attractant. For example, synthetic resins such as polyethylene, polypropylene, nylon, polyvinyl chloride, polyvinylidene chloride, and polyester, natural resins, and mixed resins thereof, synthetic fibers, natural fibers, and mixed fibers thereof, and base materials mainly made of metals such as glass, aluminum, stainless steel, and zinc are exemplified. Also, the form of the base material is not restricted, but a solid form is preferred. Sheet-like base materials (paper, woven fabric, non-woven fabric, leather, fiber, film, plastic plate, etc.) that allow coating, spraying, impregnation, accommodation, and coating of the crawling pest attractant, container-like and bag-like base materials that can accommodate the crawling pest attractant, and solid (powder, granule, etc.) base materials that can be mixed with the crawling pest attractant are exemplified. In this way, the above composite is obtained according to a conventionally known method. The content of the crawling pest attractant in the composite is not restricted as long as the effects of the present invention can be obtained.

[0057] As the adhesive trapping part, as long as a substance having adhesiveness is used, it is not particularly limited, but general-purpose ones such as rubber-based adhesives, acrylic-based adhesives, silicone-based adhesives, protein-based adhesives, and polysaccharide-based adhesives can be used. These adhesives can be any of solvent-based adhesives, emulsion-based adhesives, and hot-melt adhesives. For example, as the rubber-based adhesive, natural rubber-based adhesives, styrene-butadiene rubber-based adhesives, recycled rubber-based adhesives, polyisobutylene-butylene rubber-based adhesives, polybutene-based adhesives, and block copolymer-based adhesives can be mentioned. These adhesives can be used alone, respectively, but may also be combined in two or more kinds. By adhering or applying these adhesives to papers such as cardboard and corrugated cardboard, resin sheets such as PE, PP, PET, and PVC, and metal plates, etc., the adhesive trapping part can be constituted.

[0058] The crawling pest trap can be obtained by arranging the above-mentioned crawling pest attractant and the above-mentioned adhesive trapping part as described above. For example, by arranging the crawling pest attractant and the adhesive trapping part so that they are in contact with each other, and accommodating this in a sheet-like fiber base material, a crawling pest trap can be obtained.

[0059] The place for installing the crawling pest trap of the present invention, etc. is not particularly limited, but examples include rooms such as the entrance, kitchen, washbasin, bedroom, and living room, and inside storage furniture such as closets, chests of drawers, food storage cabinets, clothing cases, and doll cases.

Examples

[0060] Hereinafter, examples related to the crawling pest attractant, crawling pest attracting method, and crawling pest trap of the present invention will be shown. However, the present invention is not limited to these examples.

[0061] 〔Pest attraction test with the crawling pest attractant〕 1 mg of the solid creeping pest attractant with the compositions of Examples 1 to 13, Comparative Examples 1 to 5, and Reference Example 1 described in Table 1 and Table 2 (talc was used as the excipient, and the numerical values in the table are in mass %) was placed on a filter paper (1×1 cm), which was then pasted in the center of an adhesive tape (5×5 cm). This was placed on a woolen cloth (10×20 cm) on which Dermatophagoides farinae or Cheyletiella yasguri was released. After 48 hours, the number of mites captured on the adhesive tape was counted under a stereomicroscope.

[0062] The results are shown in Table 1 and Table 2. For the adhesive tape with the filter paper on which the solid creeping pest attractants of Examples 1 to 13 were placed, a clearly synergistic increase in the number of captured mites was observed, and the excellent mite attracting effect of the creeping pest attractant of the present invention was confirmed. For example, for the Dermatophagoides farinae in Comparative Example 1 containing only linoleic acid as the fatty acid, Hi the number of captured mites was 13, and for the Dermatophagoides farinae in Comparative Example 3 containing only rice bran as the plant powder, Hi the number of captured mites was 15. However, for the Dermatophagoides farinae in Example 1 containing linoleic acid and rice bran, Hi the number of captured mites was 36, and more Dermatophagoides farinae Hi could be captured than the total of the two Comparative Examples containing only single components. Furthermore, in Examples 11 to 13 containing plant powder and animal powder, a further increase in the number of captured mites was confirmed compared to Examples 1 to 10 containing plant powder or animal powder.
