[0008] Figure 1 is a perspective view of a heat vaporization type insecticide device that uses an insect control mat.

[0009] <Natural Pyrethrins> The natural pyrethrins used in this invention contain six compounds as active ingredients: pyrethrin I, pyrethrin II, cinerin I, cinerin II, jasmoline I, and jasmoline II. Natural pyrethrins can typically be obtained as an extract or dried pyrethrin powder, obtained by extracting the active ingredients from a powder made by collecting, drying, and grinding only the calyx of the flower of chrysanthemum (Tanacetum cinerariifolium or Chrysanthemum cinerariaefolium) using a suitable solvent (also called a solvent), such as an organic solvent like methanol. In addition to the six compounds mentioned above, natural pyrethrins may also contain plant-derived impurities (such as fatty acids and flavonoids).In addition to the aforementioned Chrysanthemum cinerariaefolium, other plants from which natural pyrethrins can be obtained include Calendula officinalis, Chrysanthemum coccinum, Tagetes erecta, Tagetes minuta, Zinnia elegans, and Zinnia linnearis (References 1: Adnane. H. Alain, C. & Chantal, B. 2000. The Production of Pyrethrins by Plant Cell and Tissue Cultures of Chrysanthemum cinerariaefolium and Tagetes Species. Critical Reviews in Plant Sciences, 19(1):69-89; Reference 2: Kudakasseril, GJ and Staba, EJ 1988. Insecticidal phytochemicals. In: Cell Culture and Somatic Cell Genetics of Plants. pp. 537-552.

PYRETHRUM FLOWERS, Production, Chemistry, Toxicology, and Uses. pp. 123-125, Oxford University Press.).

[0010] The plant species and varieties that serve as the source of natural pyrethrins used in this invention are not limited to those mentioned above. The cultivation methods, cultivation conditions (weather, origin, soil type, etc.), harvest time, harvest part, harvesting method, washing method, extraction method, and purification method of the plants are not particularly limited. Natural pyrethrins used in this invention also include, for example, natural pyrethrins obtained using a vector into which a gene encoding a pyrethrin biosynthesis enzyme is incorporated.

[0011] The mass ratios of the six compounds used in the natural pyrethrins of the present invention—pyrethrin I, pyrethrin II, synerin I, synerin II, jasmolin I, and jasmolin II—are not particularly limited. Any mass ratio can be set for each compound in the range of 0.001 to 99% by mass relative to the total amount of natural pyrethrins. Typically, however, the natural pyrethrins are contained in the following mass ratios: pyrethrin I at 10 to 70% by mass, pyrethrin II at 10 to 70% by mass, synerin I at 1 to 20% by mass, synerin II at 1 to 20% by mass, jasmolin I at 1 to 20% by mass, and jasmolin II at 1 to 20% by mass, relative to the total amount of natural pyrethrins. As a specific example of a mixing ratio (mass ratio), [Pyrethrin I: Synerin I: Jasmolin I: Pyrethrin II: Synerin II: Jasmolin II] = 38.0:7.3:4.0:35.0:11.7:4.0 (Reference 3).

[0012] Examples of natural pyrethrins used in the present invention include pyrethrin I (total amount of pyrethrin I, synerin I, and jasmolin I) and pyrethrin II (total amount of pyrethrin II, synerin II, and jasmolin II), with pyrethrin I at 20 to 40% by mass and pyrethrin II at 12 to 31% by mass relative to the total amount of natural pyrethrin. The total amount of pyrethrin I and pyrethrin II in the natural pyrethrin is usually 10 to 99% by mass, preferably 15 to 90% by mass, and more preferably 20 to 85% by mass, relative to the total amount of natural pyrethrin.

[0013] <Phenol-based Antioxidants> The phenol-based antioxidants used in the present invention will now be described. As phenol-based antioxidants used in the present invention, the 31 phenol-based antioxidants listed in Group A can be cited because they exhibit excellent effects in improving the thermal stability of natural pyrethrins, and one or more phenol-based antioxidants are selected and used from Group A.

[0032] <Production of the Composition> In one embodiment, a composition containing natural pyrethrin, one or more phenolic antioxidants selected from group A, and a solid carrier can be produced by mixing natural pyrethrin, one or more phenolic antioxidants selected from group A, other components selected optionally, and a solid carrier. In this case, the components may be supported on the solid carrier by adsorbing the natural pyrethrin, one or more phenolic antioxidants selected from group A, and other components selected optionally onto the solid carrier. Alternatively, the components may be supported on the solid carrier by impregnating the solid carrier with natural pyrethrin, one or more phenolic antioxidants selected from group A, and other components selected optionally. In the above manufacturing method, natural pyrethrin, one or more phenolic antioxidants selected from group A, and other components selected as desired may be pre-mixed or not pre-mixed, and each component may be supported on a solid carrier simultaneously or separately. However, it is preferable to pre-mix each component before supporting it on the solid carrier, and it is more preferable to pre-mix each component into a homogeneous solution before supporting it on the solid carrier. The methods and conditions for mixing and / or supporting each of the above components on the solid carrier can be those of known methods and conditions.

[0033] The composition of the present invention can be suitably applied to pest control mats and the like. <Pest control mats and formulations for pest control mats> One embodiment of the present invention is a pest control mat containing natural pyrethrin, one or more phenolic antioxidants selected from group A, and a solid carrier. The pest control mat may also be referred to as an electric mosquito repellent mat. In this specification, a formulation for pest control mats means a composition for manufacturing a pest control mat containing the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, other components selected optionally, and a solid carrier, wherein the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, and other components selected optionally are preferably supported on the solid carrier. As one embodiment of the present invention, a pest control mat can be manufactured by molding and processing a composition containing the above-mentioned natural pyrethrin, one or more phenolic antioxidants selected from group A, other components selected optionally, and a solid carrier into a pest control mat of a desired shape. Another embodiment of the present invention is a pest control mat in which, when the solid carrier is a blank mat material composed of a fibrous carrier or a porous carrier, the above-mentioned natural pyrethrin, one or more phenolic antioxidants selected from group A, and other components selected optionally are impregnated or adsorbed into the blank mat material.

[0034] One embodiment of the present invention is an insect control mat manufactured by molding and processing a formulation for insect control mats.

[0035] The size of the blank mat material, which is composed of a fibrous or porous carrier and used in one embodiment of the present invention, is typically 2.0 to 4.0 cm² in apparent volume before impregnation or adsorption and retention of the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, and other components selected optionally. ３ (For example, 2.2 cm x 3.5 cm x 0.28 cm (approximately 2.2 cm) ３ ), 3.8cm x 4.8cm x 0.20cm (approximately 3.6cm ３ It could be within the range of (a certain degree).

[0036] In one embodiment of the present invention, the pest control mat includes the blank mat material 2.2 cm ３ In this case, the total amount of the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, and other optionally selected components can typically be retained in an amount of 20 to 1600 mg. In another embodiment of the present invention, a pest control mat is made by impregnating or adsorbing the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, and other optionally selected components into a blank mat material of a different size than the blank mat material exemplified above, and retaining them in the blank mat material of 2.2 cm ３ Each can be manufactured by molding and processing to a desired size such that the total amount of the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, and other components selected as desired is typically 20 to 1600 mg.

[0037] Another embodiment of the present invention provides a pest control mat formulation containing the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, other optionally selected components, and a solid carrier, applied to a 2.2 cm pest control mat. ３ The insecticide can be manufactured by molding and processing the material into an insecticide mat such that the total amount of the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, and other components selected as desired is typically 20 to 1600 mg per unit. The method of impregnating or adsorbing the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, and other components selected as desired into the blank mat material, and the method of molding and processing it into a desired shape and size, can each be carried out by applying methods that are known in themselves.

[0038] Furthermore, a method for molding and processing a pest control mat formulation containing the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, other components selected as desired, and a solid carrier into a desired pest control mat can be carried out by applying a method that is itself known. For example, such a pest control mat can be manufactured in a manner similar to that of a substrate used in an air treatment apparatus described in Japanese Patent Publication No. 2009-526056. Japanese Patent Publication No. 2009-526056 discloses a substrate having a pore network structure formed by adhering granular particles, and capable of supporting air treatment chemicals such as natural pyrethrin within the pores. Such a substrate can be attached to an air treatment apparatus described in Japanese Patent Publication No. 2009-526056 and heated to release air treatment chemicals such as natural pyrethrin from the substrate. In other words, similar to the substrate of Japanese Patent Publication No. 2009-526056, a pest control mat can be manufactured by solidifying a formulation for pest control mats containing the aforementioned natural pyrethrin, one or more phenolic antioxidants selected from group A, other components selected optionally, and a solid carrier, and molding it into a predetermined shape. A pest control mat, which is one embodiment of the present invention, can appropriately contain other pest control active compounds, repellents, etc., which is expected to further improve its effectiveness.

[0039] One embodiment of the pest control mat is, for example, the pest control mat 11 used in a heat vaporization type insecticide device 200 as shown in Figure 1. In the heat vaporization type insecticide device 200 of Figure 1, the pest control mat 11 is placed on a hot plate 10, and by heating the hot plate to approximately 140 to 200°C, the natural pyrethrins and other substances held in the pest control mat are vaporized into the atmosphere, thereby controlling pests.

[0040] Further, the formulation for a pest control mat according to one embodiment of the present invention is a formulation capable of producing a pest control mat used in a heat-evaporating type insecticidal device described in, for example, Japanese Patent Publication No. 11-510055. In the heat-evaporating type insecticidal device described in Japanese Patent Publication No. 11-510055, by burning a fuel such as butane gas and heating the pest control mat to about 120 to 200°C, natural pyrethrin or the like held in the pest control mat is evaporated into the atmosphere, thereby controlling pests. That is, while the heat-evaporating type insecticidal device 200 shown in FIG. 1 heats the hot plate 10 by electric heating, the heat-evaporating type insecticidal device described in Japanese Patent Publication No. 11-510055 heats the hot plate in the device by burning a fuel such as butane gas. Although there are differences in the heat source and heating temperature between the two, the principle of evaporating natural pyrethrin or the like held in the pest control mat into the atmosphere by heating is the same.

[0041] The formulation for a pest control mat according to one embodiment of the present invention is not limited to the device shown in FIG. 1, but can be applied to a heat-evaporating type insecticidal device that uses a conventionally known pest control mat, by molding and processing it into the shape of a conventionally known pest control mat, and can all achieve excellent effects.

[0042] In one embodiment of the present invention, in the pest control mat, the total amount of the natural pyrethrin and one or more phenolic antioxidants selected from Group A is usually 1 to 30% by mass, preferably 1 to 20% by mass, more preferably 2 to 15% by mass, based on the total amount of the pest control mat; the solid carrier is usually contained in an amount of 30 to 70% by mass, preferably 40 to 60% by mass, and may further contain a solvent (also referred to as a solvent), a pigment, a stabilizer, a fragrance, and the like as appropriate.

[0043] Examples of such a solvent include the solvents exemplified for the above-described composition of the present invention.

[0044] One or more of these solvents may be contained in the pest control mat. The content is usually about 20 to 60% by mass based on the total amount of the pest control mat. Specific solvent contents include 25% by mass, 30% by mass, 35% by mass, 40% by mass, 45% by mass, 50% by mass, 55% by mass, and 60% by mass based on the total amount of the pest control mat.

[0045] In the pest control mat, the total amount of the natural pyrethrin and one or more phenolic antioxidants selected from Group A is usually about 1 to 30% by mass, preferably about 1 to 20% by mass, more preferably about 2 to 15% by mass based on the total amount of the pest control mat; the content of the solid carrier is usually prepared to be 30 to 70% by mass, preferably 40 to 60% by mass, more preferably 45 to 55% by mass based on the total amount of the pest control mat. Here, the total amount of the natural pyrethrin, one or more phenolic antioxidants selected from Group A, and the solid carrier does not exceed 100% by mass based on the total amount of the pest control mat. Further, when a solvent is included, the total amount of the natural pyrethrin, one or more phenolic antioxidants selected from Group A, the solid carrier, and the solvent does not exceed 100% by mass based on the total amount of the pest control mat.

[0046] The pest control mat has, for example, the following embodiments.

[0047] In one embodiment, it is a pest control mat containing 10 to 300 parts by mass, preferably 20 to 200 parts by mass, more preferably 30 to 180 parts by mass of one or more phenolic antioxidants selected from Group A, and 600 to 1800 parts by mass, preferably 800 to 1600 parts by mass, more preferably 1000 to 1500 parts by mass of a solid carrier selected from a fibrous carrier and a porous carrier, based on 200 parts by mass of natural pyrethrin.

[0149] Test Examples 1-31, Comparative Test Examples 1 and 2 (Stability Test of Natural Pyrethrin with Antioxidant 1) Natural pyrethrin 1, antioxidant, and BHT were mixed on an aluminum dish (circular, 3.8 cm in diameter) to the composition shown in Table 1. After heating on a 180°C heater for 1 hour, the weight-average molecular weight Mw of the resulting natural pyrethrin polymer was analyzed by gel permeation chromatography (GPC). The above procedure was repeated three times, and the average values ​​are shown in Table 1. The weight-average molecular weight Mw of the natural pyrethrin polymer is shown as a polystyrene equivalent. The polymer analysis conditions for the gel permeation chromatography (GPC) are shown below. [Polymer Analysis Conditions 1] Gel Permeation Chromatography (GPC) Pump: Shimadzu LC-20AD Detector: Shimadzu SPD-M20A Photodiode Array Detector Detection Wavelength: 254 nm Columns: Shimadzu Shim-pack GPC-803 (8.0 mm ID × 300 mm), Shimadzu Shim-pack GPC-804 (8.0 mm ID × 300 mm) (in series) Guard Column: Shimadzu GPC-800P (4.6 × 10 mm) Column Temperature: 40°C Eluent: Tetrahydrofuran Flow Rate: 1 mL / min

[0150]

[0151] When the weight-average molecular weight Mw of the resulting natural pyrethrin polymer increases, it becomes less volatile, and its efficacy decreases. The phenolic antioxidant according to the present invention shows superior efficacy in suppressing the polymerization of natural pyrethrin due to heating compared to the antioxidant BHT, and is suggested to show superior efficacy in maintaining the pest control effect of natural pyrethrin and improving thermal stability.

[0152] Test Examples 32-40, Comparative Test Examples 3 and 4 (Stability Test of Natural Pyrethrin with Antioxidant 2) 34 g of a mixture obtained by mixing natural pyrethrin 2, an antioxidant, BHT, and a solvent to the composition shown in Table 2 was filled into 45 mL liquid mosquito repellent bottles. An inner stopper with an absorbent wick (ceramic product no. HK-100, manufactured by Fuji Chemical Co., Ltd., φ7 mm, length 73 mm) was inserted and the bottles were energized for a total of 10 days (160 hours total), with the power turned ON for 8 hours and OFF for 4 hours twice a day. After this, the weight-average molecular weight Mw (polystyrene equivalent) of the natural pyrethrin polymer generated in the heated part of the absorbent wick was analyzed by high-performance liquid chromatography (GPC). The above procedure was repeated twice, and the average values ​​are shown in Table 2. The polymer analysis conditions for the gel permeation chromatography (GPC) were the same as those for [Polymer Analysis Conditions 1] above.

[0153] The BHT amounts in the table represent the total amount of BHT contained in natural pyrethrin 2 and the amount added from external sources.

[0154] When the weight-average molecular weight Mw of the generated natural pyrethrin polymer increases, it becomes less volatile, and its efficacy decreases. Furthermore, the results of the above test examples accurately reflect the test results of systems containing solid carriers such as mats. The phenolic antioxidant according to the present invention shows superior effectiveness in suppressing the generation of natural pyrethrin polymer in the heated portion of the liquid-absorbing wick compared to the antioxidant BHT. Therefore, it is suggested that even when applied to pest control mats that are heated during use, it shows superior effectiveness in maintaining the pest control effect of natural pyrethrin.

[0155] Examples 1-15, Comparative Examples 1 and 2 (Manufacturing of Insect Control Mats) The insect control solution for the insect control mats was prepared by mixing each component to the composition shown in Tables 3-1 and 3-2. 0.75 mL of this solution was spread onto each blank mat material (made of pulp and cotton linter, 0.21 cm thick, 3.5 cm long side, 2.2 cm short side, 695 mg mass), yielding insect control mats containing 100 mg of natural pyrethrin per mat (in Comparative Example 1, insect control mats containing 200 mg of natural pyrethrin per mat were obtained). Natural pyrethrin 2 was used as the natural pyrethrin.

[0156]

[0157] The BHT amounts in the table represent the total amount of BHT contained in natural pyrethrin 2 and the amount added from external sources.

[0158] (Evaluation of pest control mats) Two pest control mats prepared in Examples 1-15 and Comparative Examples 1 and 2 (Examples 1-15, Comparative Example 2: total amount of natural pyrethrin active ingredient 200 mg / treatment group, Comparative Example 1: total amount of natural pyrethrin active ingredient 400 mg / treatment group) were heated on a ceramic heater at 180°C. The amount of natural pyrethrin volatilized per hour during the first 3-4 hours after heating and the amount of natural pyrethrin remaining after 4 hours of heating were analyzed. The amount of natural pyrethrin volatilized (mg / hr) was determined by collecting the volatilized vapor at predetermined intervals using a urethane foam-packed column for a predetermined time, extracting it with acetone, and quantitatively analyzing the extract by high-performance liquid chromatography. The amount of natural pyrethrin remaining (mg) was determined by extracting it from the heated mat with acetone and quantitatively analyzing the extract by high-performance liquid chromatography. The results are shown in Table 4.

[0159] In the table, N.D. indicates that data is unavailable. The pest control mats of Examples 1 to 15, by containing a specific amount of the phenolic antioxidant according to the present invention, exhibit superior volatilization of natural pyrethrin during the 1-hour period between 3 and 4 hours after the start of heating compared to Comparative Examples 1 and 2. Furthermore, they also exhibit superior residual amount of natural pyrethrin after 4 hours of heating compared to Comparative Example 2. These results suggest that using the phenolic antioxidant according to the present invention in formulations for pest control mats suppresses the polymerization of natural pyrethrin and exhibits excellent effects in maintaining pest control efficacy even in applications involving heating.

[0160] Examples 16, Comparative Examples 3 and 4 (Manufacturing of Insect Control Mats) The insect control solution for the insect control mats, prepared by mixing each component to the composition shown in Table 5, was spread at a rate of 0.75 mL per blank mat material (made of pulp and cotton linter, 0.21 cm thick, 3.5 cm long side, 2.2 cm short side, mass 695 mg), to obtain insect control mats containing 100 mg of natural pyrethrin per mat (in Comparative Example 3, insect control mats containing 200 mg of natural pyrethrin per mat were obtained). Natural pyrethrin 2 was used as the natural pyrethrin.

[0161] The BHT amounts in the table represent the total amount of BHT contained in natural pyrethrin 2 and the amount added from external sources.

[0162] (Evaluation of pest control mats) Two pest control mats (total amount of natural pyrethrin active ingredient 200 mg / treatment group) prepared in Example 16 and Comparative Examples 3 and 4 were heated on a ceramic heater at 180°C. The amount of natural pyrethrin volatilized per hour during the first 3 to 4 hours after heating and the amount of natural pyrethrin remaining after 4 hours of heating were analyzed. The amount of natural pyrethrin volatilized (mg / hr) was determined by collecting the volatilized vapor at predetermined intervals using a urethane foam-packed column for a predetermined time, extracting it with acetone, and quantitatively analyzing the extract by high-performance liquid chromatography. The amount of natural pyrethrin remaining (mg) was determined by extracting it from the heated mat with acetone and quantitatively analyzing the extract by high-performance liquid chromatography. The results are shown in Table 6.

[0163] In the table, N.D. indicates that data is unavailable. The pest control mat of Example 16, by containing a specific amount of a hindered amine antioxidant in addition to the phenolic antioxidant according to the present invention, exhibits superior volatilization of natural pyrethrin during the 1-hour period between 3 and 4 hours after the start of heating compared to Comparative Examples 3 and 4. It also exhibits superior residual amount of natural pyrethrin after 4 hours of heating compared to Comparative Example 2. Furthermore, it exhibits superior volatilization and residual amount of natural pyrethrin compared to Example 9, which uses the same phenolic antioxidant as Example 16 but does not use a hindered amine antioxidant. These results suggest that the phenolic antioxidant according to the present invention exhibits excellent effects in maintaining the pest control effect in pest control mats used after heating, and that the combined use of a hindered amine antioxidant produces additive or synergistic effects with the above effects.

[0164] Examples 17-22 and Comparative Example 4 (Production of Insect Control Mats) The insect control solution for insect control mats, prepared by mixing each component to the composition shown in Table 7, was spread at a rate of 0.75 mL per blank mat material (made of pulp and cotton linter, 0.21 cm thick, 3.5 cm long side, 2.2 cm short side, mass 695 mg), to obtain insect control mats containing 100 mg of natural pyrethrin per mat. Natural pyrethrin 2 was used as the natural pyrethrin.

[0165] The BHT amounts in the table represent the total amount of BHT contained in natural pyrethrin 2 and the amount added from external sources.

[0166] (Evaluation of formulations for pest control mats) Two pest control mats (total amount of natural pyrethrin active ingredient 200 mg / treatment group) prepared in Examples 17-22 and Comparative Example 4 were heated on a ceramic heater at 180°C. The amount of natural pyrethrin volatilized per hour during the first 3-4 hours after heating and the amount of natural pyrethrin remaining after 4 hours of heating were analyzed. The amount of natural pyrethrin volatilized (mg / hr) was determined by collecting the volatilized vapor at predetermined intervals using a urethane foam-packed column for a predetermined time, extracting it with acetone, and quantitatively analyzing the extract by high-performance liquid chromatography. The amount of natural pyrethrin remaining (mg) was determined by extracting it from the heated mat with acetone and quantitatively analyzing the extract by high-performance liquid chromatography. The results are shown in Table 8.

[0167]

[0168] The insecticide mat formulations of Examples 17 to 22, by containing a specific amount of phosphorus-based antioxidant in addition to the phenol-based antioxidant according to the present invention, exhibit superior volatilization of natural pyrethrin during the first hour between 3 and 4 hours after the start of heating, and / or residual amount of natural pyrethrin after 4 hours of heating, compared to Comparative Example 4. Furthermore, Examples 21 and 22, respectively, exhibit superior volatilization of natural pyrethrin and residual amount of natural pyrethrin compared to Examples 10 and 11, which use the same phenol-based antioxidant as Examples 21 and 22 but do not use phosphorus-based antioxidants. These results suggest that the phenol-based antioxidant according to the present invention exhibits excellent effects in maintaining the insecticide effect in insecticide mats used after heating, and that the combined use of a phosphorus-based antioxidant produces additive or synergistic effects with the aforementioned effects.

[0169] According to the present invention, it is possible to provide a novel composition containing natural pyrethrins that maintains pest control effectiveness or exhibits excellent thermal stability.
