However, the present invention is not intended to be limited to the embodiments described below or the configurations described in the drawings.

<Poison baits for controlling myriapod pests>
The poison bait for controlling myriapod pests is a chemical solution containing the attracting ingredient, the fragrance for attracting myriapod pests of the present invention, an insect-controlling ingredient, a sugar as an ingestion-promoting ingredient, a polyhydric alcohol as a moisturizing ingredient, and water. is preferably included. The chemical solution is preferably held in a chemical solution holding body such as a gel-like body, a mat body, or a sheet body.

<Chemical solution>
[Perfume that attracts myriapod pests]
Centipedes eat a wide range of foods, from animal proteins to fruits and plant-derived substances such as tree sap, and there are various theories about their particular favorite foods. The inventors of the present invention conducted a detailed study on the attraction of centipedes and found that centipedes tend to be strongly attracted to certain types of food flavoring agents. Based on this new knowledge, as a result of containing a specific kind of food flavoring, an excellent attracting effect was recognized. Food flavors contained in the poison bait for controlling myriapod pests of the present invention include fresh milk oil, strawberry essence, acetoin, mango essence, bonito/tuna extract, camembert cheese flavor, apple oil, salted bonito extract, tuna extract, and banana. Essence, nori flavor, squid paste, and maple essence. These food flavors may be used alone, or may be used in combination. Furthermore, in the process of examining the attractability of centipedes by the present inventors, it became clear that when a surfactant is added to a poison bait for controlling myriapod pests, there is a tendency for centipede-feeding properties to decrease. rice field. Therefore, the myriapod pest-attracting flavoring agent of the present invention is preferably not used in combination with a surfactant, and preferably contains a water-soluble food flavoring that does not require the addition of a surfactant. Examples of such water-soluble food flavors include strawberry essence, acetoin, mango essence, bonito/tuna extract, camembert cheese flavor, bonito salted fish extract, tuna extract, banana essence, seaweed flavor, squid paste, and maple essence. be done. The content of the myriapod pest-attracting fragrance in the chemical solution is preferably 0.1 to 5% by weight. In the state of the poison bait for controlling myriapod pests in which the chemical solution is held in the chemical solution holder, the content of the myriapod pest-attracting fragrance is preferably 0.1 to 4.9% by weight. Within such a range, excellent attraction to myriapod pests can be exhibited. If the content of the fragrance that attracts myriapod pests in the poison bait for controlling myriapod pests is less than 0.1% by weight, the attraction of myriapod pests may be insufficient. On the other hand, if the content of the perfume that attracts myriapod pests in the poison bait for controlling myriapod pests exceeds 4.9% by weight, when the poison bait for controlling myriapod pests is installed in a closed space, etc., odors may be generated. may become excessively strong.

[Insect Control Ingredients]
The pest control component, which is one of the main components of the liquid chemical, is preferably a component effective in exterminating myriapod pests such as centipedes and millipedes. Such components include neonicotinoid insecticides and carbamate insecticides, and neonicotinoid insecticides are particularly preferred. Neonicotinoid insecticides include, for example, dinotefuran, acetamiprid, imidacloprid, clothianidin, thiacloprid, thiamethoxam, and nitenpyram, with dinotefuran being particularly preferred. Dinotefuran has optical isomers and geometric isomers based on an asymmetric carbon, and these are also included in pest control ingredients. Carbamate insecticides include propoxur, carbaryl, methomyl, and thiodicarb, and propoxur is particularly preferred. These neonicotinoid insecticides and carbamate insecticides may be used alone or in combination. The content of the pest control component in the chemical solution is preferably 0.1 to 1.0% by weight. Within such a range, the effect of the pest control component can be exhibited even when the chemical solution is retained by the chemical solution retainer. If the content of the pest control component in the liquid chemical is less than 0.1% by weight, the pest control component will be insufficient and the insecticidal effect will be insufficient. On the other hand, if the content of the pest-controlling component in the liquid chemical exceeds 1.0% by weight, the concentration of the pest-controlling component increases, making it difficult to properly prepare the liquid chemical.

[Food promoting ingredient]
The ingestion-promoting component, which is one of the main components of the drug solution, is preferably a saccharide. Examples of sugars include monosaccharides such as glucose and fructose, disaccharides such as sucrose, maltose, and trehalose, and refined sugars such as soft sugar, granulated sugar, and white sugar. preferable. These saccharides may be used singly or in combination. In addition to saccharides, sugar alcohols such as sorbitol and xylitol, and other sweeteners can be blended as food intake promoting ingredients. The content of the food intake promoting component in the drug solution is preferably 10 to 70% by weight. Within such a range, it is possible to exhibit excellent feeding properties against myriapod pests, and furthermore, since the ingestion-promoting component does not crystallize even at low temperatures, the poison bait for controlling myriapod pests can be preserved. Excellent in nature. If the content of the feeding-promoting component in the chemical solution is less than 10% by weight, the feedability of myriapod pests may be insufficient. On the other hand, if the content of the food intake promoting component in the drug solution exceeds 70% by weight, the food intake promoting component may crystallize in a low temperature environment.

[Moisturizing ingredient]
A moisturizing component, which is one of the main components of the chemical solution, is preferably a polyhydric alcohol. Examples of polyhydric alcohols include glycerin and glycols such as 1,3-butylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, diethylene glycol, triethylene glycol, hexylene glycol, and benzyl glycol. Glycerin is particularly preferred. These polyhydric alcohols may be used alone or in combination. The content of the moisturizing component in the chemical solution is preferably 10 to 40% by weight. If the content of the moisturizing component is within such a range, it is possible to prevent drying and deterioration after installation of the poison bait for controlling myriapod pests, and to maintain the attraction of the myriapod pest-attracting fragrance for a long period of time. . If the content of the moisturizing component in the chemical solution is less than 10% by weight, the poisonous bait for controlling myriapod insect pests may dry out and degrade early after installation, failing to maintain the attraction and feeding properties for centipedes. If the content of the moisturizing component in the chemical solution exceeds 40% by weight, the concentration of the moisturizing component increases, making it difficult to properly prepare the chemical solution.

[Other ingredients]
As long as it does not interfere with the effects of the present invention, the chemical solution may contain an antifungal agent, an antibacterial agent, a disinfectant, a bittering agent such as Vitrex, and a pH adjuster for molds and fungi. , a coloring agent, etc. may be added as appropriate. Antifungal agents, antibacterial agents, and fungicides include hinokitiol, 2-mercaptobenzothiazole, 2-(4-thiazolyl)benzimidazole, 5-chloro-2-methyl-4-isothiazolin-3-one, trifoline, 3 -methyl-4-isopropylphenol, ortho-phenylphenol and the like. In addition, as described above, when a surfactant is added to a poison bait for controlling myriapod pests, there is a tendency for the feeding ability of centipedes to decrease. Preferably, the poison bait does not contain a surfactant.

<Chemical solution holder>
As the chemical solution holder for holding the chemical solution containing the perfume that attracts myriapod pests of the present invention, there are a gel-like body obtained by gelling the chemical solution using a gelling agent, a mat body obtained by absorbing the chemical solution into a mat, and a sheet containing the chemical solution. A sheet body or the like that has been absorbed into the For example, when a gel-like body is used as the chemical solution holder, a gel-like poison bait for controlling myriapod pests can be formed. As a result, the poison bait for controlling myriapod pests is easy to handle, and can control myriapod pests without drying for a long period of time. Examples of gelling agents include water absorbent resins, xanthan gum, carrageenan, locust bean gum, and agar. Here, the present inventors have found that there is a difference in the feeding property depending on the type of gelling agent, and have investigated the feeding property against centipedes by focusing on the properties of the gel. It was found that there was a tendency for the ingestibility to decrease. Therefore, as the gelling agent, a water-absorbing resin having low stringiness is preferable. Examples of such water-absorbing resins include acrylic acid-based water-absorbing polymers such as acrylic acid polymer partial sodium salt cross-linked products capable of absorbing water of 100 times or more of their own weight. The drug solution and the gelling agent are preferably blended at a weight ratio of 20:1 to 70:1. If the compounding ratio of the liquid medicine and the gelling agent is within such a range, a granular poison bait with a hardness and a moisture content that are easily eaten by centipedes can be obtained, and a high control effect against centipedes can be obtained. When the compounding ratio of the chemical solution and the gelling agent is less than 20:1, that is, when the compounding ratio of the chemical solution to the gelling agent is less than 20:1, the attractiveness of the myriapod pest-attracting fragrance is sufficiently effective. There is a risk that it will not be able to effectively attract myriapod pests. If the compounding ratio of the chemical solution and the gelling agent is greater than 70:1, that is, if the compounding ratio of the chemical solution to the gelling agent is increased beyond 70:1, the viscosity of the poison bait for controlling myriapod pests becomes excessively small. This may result in inconvenience in handling.

The mat body is a fibrous carrier made of fibrous material. The sheet body is a mesh-like fiber sheet, a woven fabric, a nonwoven fabric, a knitted fabric, or the like made of a fiber material. Examples of fiber materials include natural fibers such as pulp, linter, cotton, hemp, wool, and silk, semi-synthetic fibers such as rayon, polyester (polyethylene terephthalate, polybutylene terephthalate, etc.), nylon, acrylic, vinylon, polyethylene, and polypropylene. , aramid, and synthetic fibers such as polyphenylene sulfide. When a mat body or a sheet body is used as a chemical solution holder, it is not always necessary to uniformly dissolve the fragrance that attracts myriapod pests in the chemical solution. By impregnating the chemical solution holder, it is possible to exhibit attraction to myriapod pests. Therefore, a poison bait for controlling myriapod pests can be relatively easily prepared by using a food flavor with low water solubility as the flavor attracting myriapod pests without adding a surfactant to the chemical solution.

EXAMPLES Examples relating to centipede attractability and ingestion using a poison bait for controlling myriapod pests containing the myriapod pest-attracting fragrance of the present invention will be described below. In addition, although "g" is shown as the unit of weight in the following examples, it is possible to scale up at any scale. That is, the unit "g" can be read as "parts by weight".

A drug solution was prepared by mixing 0.02 g of an isothiazoline-based antibacterial agent and 0.002 g of Vitrex as other components with purified water to make 100 g. Further, 4 g of the chemical solution was dispensed and held in a pulp mat (12 mm×6.3 mm×15 mm in thickness) to obtain a poison bait for controlling myriapod pests of Example 2.

[Example 3]
1 g of fresh milk oil and 1 g of apple oil, which are the myriapod pest-attracting fragrances of the present invention, as attracting ingredients, 0.3 g of dinotefuran as an insect-controlling ingredient, 20 g of brown sugar as an ingestion-promoting ingredient, 20 g of glycerin as a moisturizing ingredient, and others. A chemical solution was prepared by mixing 0.02 g of an isothiazoline-based antibacterial agent and 0.002 g of Vitrex as components of (1) with purified water to make 100 g. Further, 4 g of the chemical solution was dispensed and held in a pulp mat (12 mm×6.3 mm×15 mm in thickness) to obtain a poison bait for controlling myriapod pests of Example 3.

One test insect (Tobizumukade) was released into a plastic case (width 21 cm, length 37 cm, height 28 cm) poured with gypsum, and after acclimatization, the poison bait for controlling myriapod pests of Example 1 (gel-like Body) 2 g, the poison bait for controlling myriapod pests (mat body) of Example 2, and the poison bait for controlling myriapod pests (mat body) of Example 3 were placed in plastic cases, respectively, and the behavior of the Tobismukade was observed. As a result of observation, all of the poison bait agents for controlling myriapod insect pests of Examples 1 to 3 exhibited excellent attraction, feeding and lethal effects on centipedes.

Attraction confirmation tests were conducted on various food flavors, and food flavors with high attraction to centipedes were selected. In the attraction confirmation test, one test insect (Tobisomukkade) was released into a plastic case (width 21 cm, length 37 cm, height 28 cm) poured with gypsum, and after acclimatization, a petri dish containing 2 g of a food flavoring sample was placed. (3.8 cm in diameter, 1 cm in height, six small holes with a diameter of 2 mm were opened in the lid) were placed in a plastic case, and the behavior of Tobizumukade was observed for 1 hour. Three plastic cases were prepared for each sample, and the average number of contact times of Tobismukade with the petri dish was determined. FIG. 1 is a graph showing the average number of times of exposure of Tobismukade to food flavors. FIG. 1 also shows the average contact frequency (2.9 times) of Tobizumukade with a petri dish containing 2 g of tap water as a control.

As a result of the attraction confirmation test, food flavors with an average number of contact times of 5 or more were selected as food flavors with high attraction to centipedes. Specifically, fresh milk oil, strawberry essence, acetoin, mango essence, bonito / tuna extract, camembert cheese flavor, apple oil, bonito salted fish extract, tuna extract, banana essence, nori flavor shown above the dashed line in FIG. , squid paste, and maple essence were found to have excellent attractiveness with an average number of contacts of 5 or more.

[Examples 4 to 10, Comparative Examples 1 to 2, Reference Example 1]
According to Example 1, poison baits (gels) for controlling myriapod insect pests were prepared with the various compositions shown in Table 1, and an ingestibility confirmation test was carried out.

In the feeding confirmation test, one test insect (Tobisomukkade) was released into a plastic case (width 21 cm, length 37 cm, height 28 cm) filled with gypsum. Each gel of Examples 4 to 10 was presented near the head of a stationary centipede, the number of times of ingestion was recorded, and the ingestion rate (%) was determined by the following formula. Similar tests were conducted on the gel-like materials of Comparative Examples 1 and 2 and Reference Example 1. Table 1 shows the test results.
Feeding rate (%) = Ce/Cd x 100
Cd: number of presentations of gel-like body Ce: number of times of ingestion

As a result of the ingestibility confirmation test, the poison baits for controlling myriapod pests of Examples 4 to 10 containing the myriapod pest-attracting flavor having the characteristic configuration of the present invention as an attracting component contained a plurality of types of food flavors. In each of Examples 4 to 6, 8 to 10, and Example 7 containing only one type of food flavoring, the ingestion rate was 41% or more, and by being attracted by the myriapod pest-attracting flavoring, excellent It was confirmed that it is edible. In addition, the myriapod pests of Examples 4 to 9 containing the myriapod pest-attracting fragrance in the preferred content range of 0.1 to 4.9% by weight of the myriapod pest-attracting fragrance defined in the present invention. Among the control poison baits, Example 4, which has the lowest content of the food intake promoting component, has the lowest food intake rate, and Example 9, which has the highest food intake promoting component content, has the highest food intake rate. Therefore, it was confirmed that the higher the content of the food intake promoting component, the more the food intake of the poison bait for controlling myriapod insect pests. Example 10 shows a value (acetoin 0.04% by weight, bonito/tuna extract 0 .04% by weight) to contain myriapod pest-attracting fragrances. In Example 10, it was confirmed that the ingestion rate was lower than the poison bait for controlling myriapod pests of Example 6, which had the same composition other than the content of the myriapod pest-attracting fragrance. In addition, the poison baits for controlling myriapod pests of Examples 4 to 10 were agglomerates of gel-like granules. Examples 4, 6, 7, 9, and 10, in which the blending ratio of to and gelling agent was 50:1, had moderate hardness and were easy to handle. Example 8, in which the compounding ratio of the chemical solution and the gelling agent was 70:1, had a slightly lower viscosity than the others, but had sufficient handleability. As described above, the poison baits for controlling myriapod pests of Examples 4 to 10, which contain the myriapod pest-attracting fragrance having the characteristic structure of the present invention, are excellent in attractability, ingestibility, and handleability. It was confirmed that it is suitable for controlling myriapod pests.

On the other hand, the poison bait for controlling myriapod pests of Comparative Example 1, which did not contain the perfume for attracting myriapod pests as an attracting component, was the poison bait for controlling myriapod pests of Example 6, which had the same composition other than the attracting component. It was confirmed that the food intake rate decreased compared to the drug. The poison bait for controlling myriapod pests of Comparative Example 2, which contains food flavors (yogurt flavor and salmon oil flavor) different from the flavor attracting myriapod pests of the present invention as attracting ingredients, has the same composition other than the attracting ingredients. Compared with the poison bait for controlling myriapod insect pests of Example 6, it was confirmed that the ingestion rate was lowered. As described above, the poison baits for controlling myriapod insect pests of Comparative Examples 1 and 2, which do not have the characteristic configuration of the present invention, both have a low feeding rate of 37% or less, and are inferior in feeding properties. One thing has been confirmed.

The poison bait for controlling myriapod insect pests of Reference Example 1 containing a surfactant contained 60% by weight of an ingestion-promoting component in the composition other than the surfactant, and had the highest ingestion rate of 88%. Although it was the same as the poison bait for controlling myriapod pests of Example 9, the ingestion rate was 0%. From this, it was confirmed that when a surfactant is added to a poison bait for controlling myriapod insect pests, the feeding ability for centipedes is reduced. Based on the above results, among the food fragrances selected as food flavors with high attraction to centipedes in the attraction confirmation test, strawberry essence, acetoin, mango essence, bonito and tuna extract, camembert cheese flavor, salted bonito extract, and tuna Extract, banana essence, seaweed flavor, squid paste, and maple essence do not need to add surfactant as a solubilizer when preparing a poison bait for controlling myriapod pests. It was confirmed that it is more suitable as a food flavor to be contained in poison baits.

The myriapod pest-attracting fragrance of the present invention can be used as a poison bait or trap for attracting and exterminating myriapod pests such as centipedes and millipedes. It can be suitably used for centipedes such as red centipede, and can also be used for woodlice, pill bugs, and the like.
