Description

Insect method for rice cylinder

The present invention relates to a method for suppressing the migration or stagnation of pests, and preventing the odor transfer of the components of the escaping pests, and more specifically, the escaping of the escaping pest components containing the difficult-to-transfer odor. A pest insecticide suitable for use in or near a place where a crawling pest is paralyzed or has a cockroach, or an article in which the migrating pest is close to or near.

Further, the present invention relates to an insect repellent for a rice cylinder.

Conventionally, as a repellent for flying insects such as mosquitoes, cockroaches, and chironomids, many are known to be selected from N,N-Diethyl Meta Toluamide (hereinafter also referred to as DEET). The composition of citronellal, onion alcohol, menthol, limonene, geraniol, citronellol, camphenene, etc. (for example, refer to Patent Document 1).

On the other hand, limonene, terpinen-4-ol, perillaldehyde, octanal, tea tree oil, grapefruit oil, etc. are disclosed as a component of the escaping pests (for example, refer to Patent Document 2), and Revealing the use of grass A method of avoiding escaping pests of a dicarboxylic acid ester such as diethyl acrylate, dimethyl malonate or dimethyl succinate (for example, refer to Patent Document 3). However, the avoidance effect of such avoiding components is not necessarily sufficient, or has a safety problem, and it is difficult to say that the practicality is excellent.

Therefore, it is preliminarily reviewed for extracts from natural products such as cinnamon, camphor, lemongrass, sorrel, thyme, geranium, bergamot, laurel, pine, red peach, silver mint, eucalyptus and eucalyptus. Essential oils, extracts, and the like are used as a component to avoid.

As mentioned above, most of the natural evasive ingredients are those with strong odor (scent). Even if these are not unpleasant odors, many foods are handled in the kitchens where the crawling pests may be paralyzed or smashed. When used in places such as beverages, the odor of these avoiding ingredients is directly transferred to food. The odor of the beverage or the like or the escaping component is transferred to the food or the like, and the odor of the evasive component is indirectly transferred to the food by the food device or the like. Beverages, etc., thus damaging these foods. The flavor, aroma, taste, etc. of the beverage.

Therefore, in addition to excellent safety, avoiding the odor of the creeping pest component, the climbing pest may be paralyzed or smashed, for example, a kitchen place or a climbing pest may approach or have a close proximity to, for example, food. In the case of a beverage or the like, or an article such as a food container, there is a strong demand for a method for preventing the odor transfer of the escaping pest component from being suppressed.

In addition, conventionally, various corn-like countermeasures for the use of rice cylinders or storage of major pests of cereals have been proposed. For example, it is known as a quality preservative for the purpose of antibacterial, anti-mildew, and insect-proofing of rice, which is composed of allicin, capsaicin, etc., as disclosed in Japanese Laid-Open Patent Publication No. Hei 6-38678. Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. H11-222409, the entire disclosure of which is incorporated herein by reference. A tea-like repellent for tea tree oil and/or pine oil.

In addition, recently, corn-like repellents such as wasabi, mustard, pepper, and garlic are used in commercial rice cylinders. Since these medicines are foods, there is no need to worry about phytotoxicity. However, since the avoidance effect is weak, it is necessary to use them in large quantities in order to ensure the effect. In addition, because of the strong odor, it is impossible to avoid the transfer of odor to rice, and there is also a problem of irritation to people.

The best form for implementing the invention

The method of the present invention for suppressing the escaping pests or the proximity of the worms and preventing the odor transfer of the escaping pest components will contain a tendency to transfer odors An agent for avoiding creeping pests that is resistant to creeping pests and is suitable for use in or near the place where the crawling pests may be paralyzed or smashed, or the articles in which the climbing pests are near or close to or Nearby is characteristic.

The compound for avoiding the odor of the present invention which is difficult to transfer odor is highly sensitive to insect olfaction and has low sensitivity to human olfaction. As such a compound, montane-3,8- can be cited. Glycol, p-mentane-1,8-diol, ethyl 3-(N-acetamido-N-butyl)aminopropionate, picaridin (1-piperidinecarboxylic acid 2-(2-hydroxyethyl) Base-1-methylpropyl ester), 2-ethyl-1,3-hexanediol, diethyl oxalate, dimethyl malonate, diethyl malonate, dimethyl succinate, amber Diethyl acrylate, dipropyl succinate, dibutyl succinate, dimethyl glutarate, diethyl adipate, dipropyl adipate, dibutyl adipate, diethyl sebacate Ester, dipropyl sebacate, dibutyl sebacate, dimethyl phthalate, dibutyl phthalate, diamyl phthalate, dibutyl maleate, dibutyl fumarate Or a mixture of these.

As a series of escaped pest pests suitable for difficult to transfer odor, it is a series of montane-3,8-diol, p-mentane-1,8-diol, 3-(N-ethinyl-N-butyl Ethyl methacrylate, picaridin (2-(2-hydroxyethyl)-1-methylpropyl 1-piperidinyl), 2-ethyl-1,3-hexanediol or the like mixture.

As a series of escaping pests that are more suitable for difficult to transfer odor, it is a series of montane-3,8-diol, p-mentane-1,8-diol, 3-(N-ethinyl-N-butyl Ethyl alanine propionate, picaridin (2-(2-hydroxyethyl)-1-methylpropyl 1-piperidinecarboxylate) or a mixture of these.

As a series of escaping pests that are more suitable for difficult to transfer odors, it is a mixture of montan-3,8-diol, p-mentane-1,8-diol or the like.

Further, it is especially preferred for the cyclohexane-3,8-diol.

Any of the above compounds may be a synthetic product or a natural component.

Further, among the above compounds, although there are a trans form and a cis form based on a stereo structure for montan-3,8-diol and p-mentane-1,8-diol, in the present invention, both of them may be used. A mixture of any ratio of isomers.

The substance contained in the mendelane-3,8-diol and/or the paraben-1,8-diol-based lemon tart essential oil is known as a repellent component of a repellent for flying insects such as mosquitoes, but There is still no review report on the effect of climbing pests.

On the other hand, regarding the montan-1,8-diol, although it has a number of avoiding effects on mosquitoes, it has never been noticed in the past.

The escaping pest repellent which can be used in the present invention may be composed only of the above-mentioned evasive pest component, but various components are usually added to prepare various forms.

The ratio of the content of the evasive pest component or the total amount of the evasive agent varies depending on the type of the evasive agent.

For example, when a liquid such as a liquid agent is used, it is preferably set to 0.2 to 20% by mass. When the amount is less than 0.2% by mass, the effect of avoiding is insufficient. On the other hand, when it exceeds 20% by mass, stickiness or the like occurs, which is not practical.

Further, when it is carried in a form in which the carrier is used, it is suitable to carry out 0.01 to 100 mg/cm ² while adjusting the amount of volatilization per 24 hours of the escaping pest component to 0.2 to 200 mg.

The use of a liquid-like crawling pest repellent such as a liquid agent is difficult to transfer It is preferable to use a solvent having a central boiling point of 160 ° C or higher as a potency enhancer to remove the odorous component. Examples of such a solvent include glycol, glycol ether, and an aliphatic hydrocarbon solvent, and particularly preferred are glycol, glycol ether, and kerosene.

Specifically, for example, propylene glycol, 1,3-butylene glycol, 1,2-hexanediol, diethylene glycol monobutyl ether, propylene glycol monobutyl ether, dipropylene glycol monomethyl ether, 1-methoxy- 1,2-propanediol, etc., but is not limited thereto.

When using montan-3,8-diol and/or p-mentane-1,8-diol as a component for avoiding escaping pests, if the glycol or glycol ether is blended, the effect of the avoidance effect is considered to be enhanced. However, when it is combined with glycol or glycol ether in the pyrethroid insecticidal component, the known phenomenon of the insecticidal effect is reduced as a control result. It is speculated that this is due to the different types of worms that are evading the cultivating pests, which are greatly involved in the evasive action, and the combination of montane-3,8-diol and/or paraben- 1,8-diol, and a central boiling point value of 160 ° C or more, especially glycol, glycol ether solvent or kerosene is particularly effective in the performance of the avoidance effect. Further, the compounding amount of the potency enhancer is 0.5 times or more of the component of the climbing pest, and it is suitably 2.0 to 50 times.

Further, among the escaping pest repellents of the present invention, a plant-derived deodorant component such as a green tea extract or a persimmon extract can be added. In addition, depending on the intended use, it is also possible to add a green leaf alcohol or a green leaf aldehyde called "green scent" to adjust the aroma, and to impart a pressure-relieving effect.

The escaping pest repellent used in the present invention can be used in combination with the use, and various types such as liquid, gel, solid, and flake are used. state.

In the preparation of the liquid preparation, in addition to water, a lower alcohol such as ethanol or isopropyl alcohol, an ester or ether solvent, or a surfactant, a solubilizing agent or a dispersing agent may be suitably used. Further, in addition to this, a stabilizer, a pH adjuster, a colorant, and the like may be appropriately blended.

Further, examples of the gelling agent used for preparing the gel-like body include carrageenan, celery gum, garland gum, gelatin, aluminum octoate, and 12-hydroxystearic acid.

Regarding the liquid form of the migrating pest repellent, the details are as follows.

As a prescription, it contains 0.2 to 20% by mass of a non-walking pest component, 0.2 to 40% by mass of a solvent having a central boiling point of 160 ° C or higher, a lower alcohol and water, and if necessary, a surfactant-based aqueous solution. Preferably, the repellent is suitable for use in a direct dispersion mode, guided by the wick to the evaporation portion, and dispersed in a manner that avoids the stalking pest component in the space.

As a lower alcohol, ethanol or isopropanol is representative, and ethanol is preferred in terms of performance. In addition, when the amount of the lower alcohol is more than 10% by mass, the risk of fire gas is increased, and a non-hazardous substance that does not comply with the fire protection law is generated.

In order to avoid the stability and dispersibility of the components of the climbing pest, the surfactant is preferably a combination of a higher alkyl amine oxide surfactant and a nonionic surfactant.

Examples of the higher alkyl amine oxide-based surfactant include, for example, lauryl amine oxide, stearic acid amine oxide, melamine propyl dimethyl amine oxide, and the like, and as a nonionic surfactant, Ethylene oxide hardened castor oil, polyoxyethylene higher alkyl ether (polyoxyethylene lauryl) Ether, polyoxyethylene oleyl ether), polyoxyethylene higher fatty acid ester, polyoxyethylene polyoxypropylene alkyl ether, and the like.

The escaping pest repellent agent thus obtained is, for example, placed in the various containers as a escaping pest insect product, and is disposed in a place where it is necessary to suppress the walking pests or the vicinity, and is suitable for directly dispersing the liquid agent. The way.

Further, the escaping pest repellent agent obtained as described above is suitably used, for example, to be filled in a container body having a wick, and is used as a migrating pest-avoiding product, and is provided in a place where it is necessary to suppress squatting pests or close to it. The manner in which the wick is dispersed to avoid the composition of the stalking pests in space.

If necessary, it is also energized to be heated to the evaporation portion which is disposed in the vicinity of the upper side of the wick to promote dispersion.

The wick is a material which is stable to the repellent and which absorbs the aqueous solution by capillary action. Specific examples of the material include plastic fibers such as nylon and polyester, natural fibers, and wood. Among them, the plastic fiber or natural fiber felt wick is easy to use, and is formed into a rod shape or a core shape having an outer diameter of 3 to 10 mm for use.

Typically, the evaporation portion of the repellent repellent is disposed above the wick. In the case of natural dispersion, the structure of the evaporation portion is a felt or a sheet, and as the material, a plastic fiber such as nylon or polyester, natural fiber, wood or the like can be used as in the case of the wick. Among them, it is suitable for the felt or flaky shape of plastic fiber or natural fiber, the thickness is 2~15mm, and the surface area is slightly rounded with a surface area of 10~60cm ² . If this is disposed on the top surface of the contact wick, The absorbed repellent moves from the wick to the evaporation section and is slowly dispersed in the air. Usually adjusted to avoid the amount of evaporation of the avoidant in the air every day is 1~8mL, the effective duration is 1~2 months.

On the other hand, when it is applied to a system heated to 50 to 130 ° C, an appropriate heater is attached to the evaporation portion.

As a place where stalking pests may be paralyzed or smashed, examples include stalking pests such as cockroaches (Blattella germanica, Periplaneta fuliginosa, and Periplaneta americana). , Japanese cockroach (Periplaneta japonica), brown cockroach (Periplaneta brunnea), Kyoto Aachen (Asiablatta kyotensis), ants (including black ants, red ants, double needle ants, etc.), worms (Psocoptera), specimens Anobiidae, Sitophilus zeamais, Dermestidae, cockroaches, etc., of course, mosquitoes, cockroaches, cockroaches, flies, moths, clothing moths, etc. The place where there is a shackle or a shackle, specifically, the kitchen (in the storage cabinet around the sink, under the sink, around the rice tank, in the drawer or cabinet of the food (dry matter, sugar, seasoning, etc.)), under the refrigerator In and around the food cabinet, lockers, toilets, sinks around the washbasin, drawers in the washstand, porch and other houses, warehouses, restaurants, etc.

Examples of the articles in which the climbing pests are close to or close to each other include various foods (for example, fresh foods (vegetables, fish, meat), processed foods, seasonings, dried foods, etc.), drinks, foods, and the like.

The above-mentioned rodent eats fine pieces or mold of food, and the micro-worms of 1.5 mm or less in the house are generally visible in the house. The corn-like system causes damage to rice grains and cereal flour, and is an important pest of rice, wheat, and maize. About 2~4mm The beetle, the scorpion worm, is mainly made up of food such as firewood, dried fish, and cereals. It also harms the beetle of fiber products of about 3 to 5 mm in length, and the dried foods such as the opposite lines of the insects or the tatami and wood cause damage. About 3mm beetles, ants collect foods such as sugar, snacks, dried fish, etc., and most individuals invade the house, causing unpleasant worms. Moths occur in dry foods such as snacks, flour, rice, beans, etc. Cereal worms, but these various pests are in general households. For example, there are many rice, flour, snacks, dried fish, sugar, dry matter, etc. in the kitchen, and it is easy to occur in places where moisture is prone to mold.

In the method of the present invention, the migrating pest repellent which impregnates or maintains the above-mentioned evasive stalking pest component in various solid carriers is suitable for use in or near a place where escaping pests may be paralyzed or smashed. Or the crawling pests may be close to or near the article or in the vicinity thereof, or may naturally evaporate from the solid carrier to avoid the creeping pest components, and use the air moving or convection in the object space to evade the active ingredients throughout the object. The whole space.

A migrating pest repellent that is impregnated or retained in a solid carrier is placed, for example, in a container having an opening portion that can evade the escaping pest component, for example, placed in a plastic container as a evasive walking pest. The product is disposed in a place where it is necessary to suppress the walking or pesting of the walking pest, and is applicable to a method of directly dispersing the component which avoids the walking pest.

Examples of the solid carrier include cellulose carriers such as pulp, thread, and enamel, and inorganic materials such as nylon, polyvinyl alcohol, polyethylene, polystyrene, and polypropylene carrier, silicate, cerium oxide, and zeolite. A sublimation carrier such as a porous carrier, trioxane or adamantane, etc. The insect component and the solvent required for the reaction are equivalent to this, and a migrating pest repellent such as a solid, a flake, or a granule can be prepared.

In addition, the carrier concept of the present invention also includes a gel formed by a gelling agent or a solid formed by a curing material.

Examples of the gel include a gelling agent such as carrageenan, celery gum, ylang gum, gelatin, aluminum octoate, and 12-hydroxystearic acid, and the gelling agent for avoiding escaping pest components and other components. As the solid matter, a solidified material such as soap, wax, gypsum, bone glue, scent, or plastic is used, and the stalking pest component and other components are avoided, and a solid matter containing the escaping pest component and other components is formed. And so on.

In the carrier, it is particularly easy to use a carrier made of cellulose such as pulp, thread, or enamel, or a carrier made of nylon, polyvinyl alcohol, polyethylene, polystyrene or polypropylene, and if it is carried by 0.01 to 100 mg/cm ² This avoids the stalking pest component, and at the same time makes the volatile component of the avoidance component 0.2 to 200 mg per 24 hours, achieving an excellent avoidance effect on the migrating pest, and is particularly suitable for use because it does not transfer the odor of the evading component. A method of preventing the transfer of odors from the stalking pest components in the kitchen, under the refrigerator, or around the food cabinet.

In addition, under the conditions of air movement and insufficient convection, a blower mechanism such as a fan or an air conditioner is used to cause the movement or convection of the artificial air to efficiently escape the evapotranspiration of the stalking pest component.

As a specific example mentioned above, a so-called rotary insect control apparatus etc. are mentioned, for example.

In addition, ultrasonic wave atomization can also be utilized to implement the scope of the present invention. System, pressure atomization system, fumigation. Fumigation systems, etc., of course, can also be applied to a variety of insect-proof or insect-proof devices.

The anti-walking pest products thus obtained are provided in the kitchen (in the storage cabinet around the sink, under the sink, around the rice tank, in the drawer or cabinet of the food (dry matter, sugar, seasoning, etc.), under the refrigerator, In and around the food cabinet, the locker, the toilet, the sink around the washbasin or the drawer of the washstand, the house of the porch, the warehouse, the restaurant, etc., of course, the cockroach (German cockroach, black-breasted cockroach, American cockroach, Japanese cockroach, brown cockroach, Kyoto Aachen, etc.), ants (including black ants, red ants, double needle ants, etc.), worms, specimens, corn elephants, locusts, heartworms, large valleys Tenebroides mauritanicus (including Tribolium castaneum, etc.), The, Thereuonema tuberculata, Armadillidium vulgare, worm (Oniscidea), horse land, butterfly moth larvae, mites, etc. Climbing pests, and pests, cockroaches, larks, flies, moths, and moths, etc., to achieve practical avoidance effects. Then, since the escaping pest-resistant product achieves a practical avoidance effect for a period of from 1 month to 2 months, the odor does not shift, so that it is highly practical to prevent the odor of the escaping pest component. The method of transfer.

The insect repellent for the rice cylinder of the present invention is usually prepared by adding various components to the cyclohexane-3,8-diol to prepare an insect repellent composition, which is suitable for various types of insect repellents for rice cylinders. The amount of the molybdenum-3,8-diol relative to the rice insecticide is different depending on the type of the insect repellent used in the rice cylinder, but it is preferably 0.02 to 1.0 g per 10 L of the set cylinder capacity. .

If the insect repellent for the rice cylinder of the present invention thus obtained is disposed in the rice cylinder, the pests close to the food such as corn, scorpion, insect, specimen, cockroach, ant, etc., of course, , cockroaches, cockroaches, flies, moths Pests such as genus and clothing moths achieve practical insect control effects for a period of one month to two months. Next, in the present invention, the montan-3,8-diol used as an insect-repellent component is extremely weak in odor compared with the conventional wasabi, mustard, ginger or pepper, and hardly shifts the odor to the rice, so the utility is practical. Extremely high.

Specific examples of the anti-walking pest insect products which can be used in the present invention will be described with reference to the drawings, but the present invention is of course not limited thereto. Fig. 1 to Fig. 4 show a type of escaping pest-resistant insect product which is placed in a container by impregnating or holding a type of escaping pest repellent which avoids the stalking pest component in a solid carrier. The escaping pest-resistant insect product is formed in a composition in which the container 1 is impregnated with a chemical impregnated body 2 (walking pest repellent) containing a drug containing a component for avoiding escaping pests, and has a thin plate shape as a whole. The container 1 has an opening for evaporating the component of the escaping pest.

As described above, by having a thin plate shape, it can be easily placed in a narrow space of a drawer or a food container, and by placing the chemical impregnated body 2 in the container 1, it is possible to prevent the inclusion of the escaping pest component. The drug is directly attached to the hands, food, food, setting place, and the like.

Example

Next, a method for preventing the odor transfer of the anti-walking pest component of the present invention will be described in more detail based on a specific embodiment.

Examples 1 to 4 and Comparative Examples 1, 2 [Filter paper avoidance effectiveness test]

The various migrating pest repellent samples (Examples 1 to 4 and Comparative Examples 1 and 2) shown in Table 1 were prepared, and impregnated with a predetermined amount of filter paper having a diameter of 15 cm, and air-dried. 30 pieces of corn or double needle ants were placed in a plastic container (40 cm × 60 cm), and the filter paper was placed in the container at the same time, and the filter paper was coated on a paper having a diameter of 15 cm having 8 entrances and exits (0.5 cm in diameter). cup. Similarly, a filter paper and a paper cup of the same size as those used for the sample processing were set as a non-treatment zone.

The water and the experimental animal feed were placed in the center, and the number of insects lurking in the two paper cups after 8 hours was counted, and the avoidance rate was calculated according to the following formula. The test was repeated 4 times, and the average value is shown in Table 1.

Repellent rate (%) = [number of latent insects in no treatment area - number of latent insects in sample processing area] / [number of latent insects in no treatment area + number of latent insects in sample processing area] × 100

As a result of the test, the escaping pest repellent of the present invention is based on the action of montane-3,8-diol and/or p-mentane-1,8-diol as a component of the evasive migrating pest. The effect of avoiding corn or double needle ants is far better than that of the comparative example of rosemary oil or thyme. Further, the avoidance effect is further enhanced by blending a solvent having a boiling point of 160 ° C or higher, particularly a glycol-based or glycol ether-based solvent.

In contrast, as shown in Comparative Example 1 and Comparative Example 2, the avoidance effect of rosemary oil or thyme was low.

Examples 5 to 19 and Comparative Examples 3 to 7 [Filter paper avoidance effectiveness test]

Various migrating pest repellent samples (Examples 5 to 19 and Comparative Examples 3 to 7) indicated in Table 2 were prepared, and impregnated with a predetermined amount of filter paper having a diameter of 15 cm, and air-dried. Place 15 black-breasted cockroaches (male male, female, and larva) in a plastic container (40cm × 60cm), and set the filter paper In the container, the filter paper was simultaneously coated on a paper cup having a diameter of 15 cm having four entrances and exits (width 2 cm, height 2 cm). Similarly, a filter paper and a paper cup of the same size as those used for the sample processing were set as a non-treatment zone.

The water and the experimental animal feed were placed in the center, and the number of turns in the two paper cups after 8 hours of counting was counted, and the avoidance rate was calculated according to the following formula. The test was repeated 8 times, and the average value is shown in Table 2.

Repellent rate (%) = [number of latent insects in no treatment area - number of latent insects in sample processing area] / [number of latent insects in no treatment area + number of latent insects in sample processing area] × 100

As a result of the test, the escaping pest repellent of the present invention is based on the combination of montane-3,8-diol and/or para-methane as a component of the escaping pest. 1,8-diol, 3-(N-ethylindenyl-N-butyl)aminopropionic acid ethyl ester, picaridin, dibutyl succinate, showing that the effect of avoiding cockroaches is far better than comparison Examples of menthol, terpinen-4-ol (disclosed in JP-A-11-60421), thyme or Japanese peppermint oil. Further, this avoidance effect is greatly enhanced by blending a solvent having a boiling point of 160 ° C or higher, particularly a glycol-based or glycol ether-based solvent, as shown in Example 15. Further, it was judged from the comparison of Example 13 and Example 14 that it was effective in combination with adamantane, and this tendency was also the same as that of violet lanylone or allylo-ionone.

In contrast, as shown in Comparative Example 3 to Comparative Example 7, the evading effect of menthol, terpinen-4-ol, thyme or jasmine oil was low, and the glycol ether solvent used as the potentiator was also used alone. The avoidance effect is almost completely absent.

Examples 20 and 21 and Comparative Examples 8 to 10 [Field evasion effectiveness test]

A pulp pad (5×10 cm) impregnated with various escaping pest components is housed in a plastic container having a predetermined volatilization hole (the total area of the surface is 35 cm ² and the total surface area of the container is 28%) 5.8 × 10.8 cm), various creeping pest repellent samples shown in Table 3 were prepared. The amount of these components to be evaded per 24 hours is shown in Table 3.

Place 60 of the German cockroaches at 2m ^{2 to} allow domestication to freely ingest water and solid feed. A repellent sample and an appropriate amount of solid feed were placed in a plastic container, which was capped with a gap (1 cm) and placed in the field. In addition, containers of the same size are set as unprocessed areas. The stagnation rate was calculated by the following formula by counting the enthalpy that was lurking in the container over time. The combined results are shown in Table 3.

Repellent rate (%) = [number of latent insects in no treatment area - number of latent insects in sample processing area] / [number of latent insects in no treatment area + number of latent insects in sample processing area] × 100

As a result of the test, the immersion pest repellent of the present invention (Examples 20 and 21) impregnated with montan-3,8-diol or p-mentane-1,8-diol was compared with other vanilla-containing components. In comparison, even if the amount of impregnation and the amount of volatilization are small, the high avoidance rate is exhibited, and the odor is hardly felt, so that it is extremely practical.

On the other hand, the escaping pest repellent of the comparative example containing eucalyptus oil, thyme oil or rosemary oil is particularly unsuitable for use in the kitchen even if the volatilization amount is high, the avoidance effect is low, and the odor is too strong.

Examples 22, 23 and Comparative Example 11 [Synthetic plate avoidance efficacy test]

Place 60 pieces of German cockroach at 2m ^{2 to} allow domestication to freely ingest water and solid feed. The composition was mixed with various escaping pest components in a liquid preparation, filled in a spray bottle, and applied to a synthetic plate of 20 × 20 cm to obtain a coating amount as shown in Table 4 (corresponding to a component for avoiding creeping pests). The two composite plates were treated in the opposite direction, and a gap (0.5 cm) was provided to be placed on the site. Further, a chemically treated composite panel of the same size was similarly provided as a non-treatment zone. The enthalpy of the latent in the composite plate was counted over time, and the avoidance rate was calculated according to the following formula. The combined results are shown in Table 4.

Repellent rate (%) = [number of latent insects in no treatment area - number of latent insects in sample processing area] / [number of latent insects in no treatment area + number of latent insects in sample processing area] × 100

Example 24

The mixture contains 1.0% by mass of paraben-3,8-diol, 3.0% by mass of propylene glycol, 1.2% by mass of laurylamine oxide, 3.0% by mass of polyoxyethylene oleyl ether, 7.0% by mass of ethanol, 1.0. % by mass as deodorant A green pest extracting agent (Example 24) of the present invention containing green tea extract, 0.02% by mass of citric acid, and 83.78% by mass of purified water. In addition, the water-based repellent is in compliance with non-hazardous materials in the fire protection law.

130 g of the climbing pest insect repellent of the present invention was filled in a transparent polyester container body, and a plug of a rod-shaped felt wick having an outer diameter of 7 mm was inserted into the upper opening. The evaporating portion support was placed, and a disc-shaped felt evaporation portion having a thickness of 5 mm and a diameter of 5.2 cm was attached to contact the top surface of the wick to prepare a placement type insect repellent.

When the insect-proof device was placed in the kitchen, it did not feel strong odor. After about 2 months, there was no trouble.

Example 25

2.0% by mass of p-menthan-1,8-diol, 40% by mass of diethylene glycol monobutyl ether, 0.05% by mass of dibutylhydroxytoluene as a stabilizer, and 57.95 mass% of purified water A creeping pest repellent of the present invention in the form of a liquid (Example 25).

After filling 45 mL of the polypropylene container body, the plug and the inorganic substance are calcined and wicked, and heated and evaporated at a heater temperature of 100 ° C, and the so-called liquid electric mosquito-repellent insect-proof tool is applied.

In the same manner as in Examples 22 and 23, the insect-resistant article showed an excellent avoidance effect against climbing pests such as cockroaches or house dust mites.

Example 26

Modulation of 15% by mass of montan-1,8-diol, 25% by mass of violet A liquid preparation of ionone and 60% by mass of kerosene (boiling point: 170 ° C), impregnated with 1.0 g of a non-woven fabric (50 cm × 50 cm) made of a multilayer structure of polyester and polypropylene, and formed into a sheet. The walk-behind pest repellent of the present invention (Example 26). When this climbing pest repellent is used as a cushion under the pet bait, the cockroach, the worm or the ant is not seen near the bait for about one month, and the comfortable environment can be maintained.

Example 27

A 30% by mass solution of montan-3,8-diol, 30% by mass of exercene, and 40% by mass of 1,3-butanediol was prepared. The 0.6 g of the carrier having a ventilating outer diameter of 4.0 cm was held in a protective case made of polycarbonate (outer diameter: 4.5 cm, thickness: 8 mm) to prepare the escaping pests of the present invention. Agent (Example 27).

Next, it is applied to a so-called rotary insect-proof device in which the protective casing is attached to the rotary shaft of the rotary drive device and rotated by a rotary drive device (rotation speed: 1200 rpm) to evaporate the avoidance component by centrifugal force. In the same manner as in Examples 22 and 23, the insect-repellent device showed an excellent avoidance effect against climbing pests such as cockroaches or house dust mites.

Example 28

The burr mechanism pad having a size of 5×10 cm and a thickness of 1 mm is used to contain 200 mg of montane-3,8-diol and 5 mg of green tea extract, and the pad is accommodated in the opening (the total area of the hole) The polyester container (5.8×10.8 cm) relative to 25% of the total surface area of the container is used to prepare the walking damage of the present invention. Insecticide (Example 28).

When the migrating pest repellent was placed near the food cabinet or rice tank in the kitchen, about one month, no cockroaches, ants, worms, specimens, corn elephants, etc. were found in the kitchen.

Example 29

The walk-through pest repellent prepared according to Example 28 is placed in a drawer of a food container (top line) to close the state of the drawer, and after 10 days, the migrating pest repellent is removed. The degree of odor was transferred to the food and food (face line) in the drawer, and a 10-person monitor performed a functional test.

The results are shown in Table 5, and any of the food and food (top line), whether the odor is transferred or not concerned.

Example 30: Induction test of pests and human sense of smell Test method

The test was carried out using the test apparatus shown in FIG.

The impregnation dilution test agent was made into a certain concentration of acetone solution on a filter paper (1.0 × 1.0 cm), and then air-dried into a test filter paper (symbol 5 in Fig. 13). In test tube 20mm × 20cm) (in Figure 13, symbol 3) at the bottom, put the filter paper (0.5 × 0.5cm) attached to the German cockroach dung (Figure 13, symbol 6) and test filter paper, put into 10 German cockroaches young adult , covered with absorbent cotton (symbol 4 in Figure 13,). The test tube was placed horizontally and allowed to stand for distribution after 1 night and the presence or absence of odor. The avoidance effect is to calculate the ratio of the enthalpy distribution in the vicinity of the test filter paper, and compare the effects.

Further, the vicinity of the test filter paper was the position A (symbol 8 in Fig. 14), and the position B (symbol 7 in Fig. 14) was used, and the odor was divided into four stages according to the induction.

Distribution ratio = number of turns of position A / (number of turns of position A + number of turns of position B)

The test results are summarized in Table 6.

Judgment of effect: ◎: 0, ○: 0.01~0.30, △: 0.31~0.70, ×: 0.71~1.00 Odor difference: -: no odor, +: slight odor, ++: obvious odor, + ++: Strong smell

As a result of the test, when the montan-3,8-diol was volatilized in the space, the concentration of the odor was hardly observed by humans, and the high avoidance effect against the cockroaches was exhibited. That is, a compound which is highly sensitive to the olfactory sense of pests of the montan-3,8-diol system and has low sensitivity to human olfaction is actually proved.

In contrast, volatile rosemary oil, citronella oil, perillaldehyde and terpinen-4-ol (control group), in recognition of the concentration of the avoidance effect, also showed strong odor to humans, and was regarded as pests. And a group of compounds with small differences in sensitivity to human olfaction.

In addition, it is considered that 3-(N-ethinyl-N-butyl)aminopropionic acid ethyl ester, picaridin and diethyl sebacate are located between the paraxane-3,8-diol and the control group, The sensitivity of human olfaction is low. On the other hand, the evasive effect on cockroaches is slightly inferior to the trend of montane-3,8-diol.

In addition, it is confirmed that other cockroaches other than German cockroach (Black-breasted cockroach, American cockroach, Japanese cockroach, brown cockroach, Kyoto Aachen, etc.) have the same sensitivity as the above test.

So far, in the development of space repellents, although the importance of volatility factors, the present invention is based on the search for high sensitivity to pest olfaction, on the other hand, compounds that are less sensitive to human olfaction and the application of this effective method is technology Thought, obvious novel idear.

Example 31

About 3g 2 mm of cellulose beads, containing 210 mg of paraben-3,8-diol, 6 mg of green tea extract, and 20 mg of kerosene (aliphatic hydrocarbon solvent), and accommodating the beads to be permeable to adhesion Polyester non-woven fabric and many A bag (5 x 10 cm) made of a plastic film of a small hole of 1 mm (a double-sided tape for fixing is attached to the upper cover of the rice cylinder) to prepare an insect repellent for a rice cylinder of the present invention (Example 31).

When the rice tank was fixed with the insect repellent on the top of the rice tank (capacity: 10L), after about one month, no corn elephant, mites, worms, specimens, cockroaches, etc. were found in the rice tank.

Examples 32 to 34 and Comparative Examples 12 to 16: insecticidal efficacy test

According to Example 31 (but replacing about 3g) A 2 mm cellulosic bead was used, and a pad of 3 mm and a thickness of 1 mm was used. The insect repellents for various rice cylinders shown in Table 7 were prepared and placed in a closed container of about 6 L in a container. Each of the 30 corn elephants and the adult insects were placed, and the lethality after 7 days was determined as shown in Table 7.

As a result of the test, the insect repellent for the rice cylinder of the present invention is based on the action of the molybdenum-3,8-diol as an insect-repellent component, and the effect of avoiding the corn or the specimen is significantly higher than that of the traditional wasabi component or pepper. The composition exhibits excellent insecticidal efficacy, and it is considered to have high practicability as an insecticide close to food pests when a high avoidance effect on montan-3,8-diol is added. In addition, the insecticidal efficacy is markedly enhanced by blending the deodorant component of the green tea extract or the persimmon extract from the plant.

Further, any of them has a low risk of fire and is excellent in the use surface.

On the other hand, as shown in the comparative example, Mayol, which is also a terpene-based compound, or a general thyme which is a component of avoidance, has low insecticidal efficacy and strong odor, and is not suitable as an insect-repellent component for insecticides for rice cylinders.

Examples 35 to 37 and Comparative Examples 17, 18: Odor transfer test

It was placed in a rice-milk tank (capacity: 10 L), and an insect repellent for a rice tank prepared in accordance with Examples 32 to 34 was placed. After 5 days, the insect repellent for the rice cylinder was removed, and to what extent the odor was transferred to the surrounding rice, a 10-person monitor performed a functional test. The results are shown in Table 8.

As a result of the test, the insect odor of the rice cylinder of the present invention derived from natural paraben-3,8-diol as an insect-repellent component does not transfer to rice, and the toxicity to humans and animals is very low, so Very practical.

On the other hand, the wasabi component or the capsicum component is strong in odor, so that the odor is not prevented from shifting to rice, and it has the disadvantage of being irritating to humans.

Example 38: Confirmation of the avoidance effect on corn elephants Test method

The test was carried out using the test apparatus shown in Fig. 14.

The impregnation dilution test agent was made into a certain concentration of acetone solution on a filter paper (1.0 × 1.0 cm), and then air-dried to test paper (Fig. 14, symbol 5). In test tube 20mm × 20cm) (in Figure 14, symbol 3) at the bottom, put 10 germ rice (Figure 9, symbol 9) and test filter paper, put into test insects (corn elephant adult 10 / area), with absorbent cotton (Figure In 14th, the symbol 4) is stamped. The test tube was placed horizontally and the corn image distribution and odorlessness were observed after 3 hours. The avoidance effect is to calculate the ratio of the enthalpy distribution in the vicinity of the test filter paper, and compare the effects.

Further, the vicinity of the test filter paper was the position A (symbol 8 in Fig. 14), and the position B (symbol 7 in Fig. 14) was used, and the odor was divided into four stages according to the induction.

Distribution ratio = number of turns of position A / (number of turns of position A + number of turns of position B)

The test results are summarized in Table 9.

Judgment of effect: ◎: 0.00, ○: 0.01~0.30, △: 0.31~0.70, ×: 0.71~1.00 Odor difference: -: no odor, +: slightly odor, ++: obvious odor, + ++: Strong smell

Industrial use

The invention is in the field of controlling walking pests and should be available.
