DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for controlling flying insects of the order Diptera, and more particularly to a method for controlling insects using a transpirable preparation.

[0002]

2. Description of the Related Art As a typical evaporation system for insecticides currently on the market, there is an aerosol agent which releases a drug into the air by using a propellant such as a liquefied gas as a driving force. Since it emits a large amount of propellants and solvents into the air in addition to the necessary chemicals, the impact on the environment has recently been regarded as a problem. In addition, as preparations that do not emit extra components than aerosol preparations, there are transpiration preparations represented by mosquito coils and mat-type or liquid-type electric mosquito filters, but these preparations use fire,
There is a problem that it can be used only in a place where an AC power source exists. Therefore, the direction of the function required for the insect pest control agent in the future is that a formulation that solves these problems, that is, one that does not release an excess into the air and does not limit the place where it is used. for that purpose,
There is a need for a system that releases transpirable drugs with low energy. Factors that determine the amount of drug transpiration include the surface area of the support, wind power, heat, air pressure, and the like. However, it is not practical to fluctuate the atmospheric pressure because a large-scale device is required, and a device that fluctuates the surface area of the holding body, wind power, and heat is within the range that can be put into practical use. Has been done.
As a specific example, JP-A-9-289855 (applicant: Sumitomo Chemical Co., Ltd.) discloses a carrier having a through hole (surface area / volume) in the range of ¹ to 20 cm ^-1. Describes an insect repellent which holds an insect repellent compound which is volatile at normal temperature. JP-A-9-308421 (applicant: Sumitomo Chemical Co., Ltd.) describes an insect repellent that allows a room-temperature volatilizable insecticidal compound to be held in a tubular material having many foldable paper holes. ing. In addition, Shokai 6

WO 96/04786 (Applicant: Earth Pharmaceutical Co., Ltd.) describes a formulation in which a fan releases a drug into the air. JP-A-56-75411 (applicant: Junro Katsuta), JP-A-56-97201 (applicant: Toyo Ink Manufacturing Co., Ltd., etc.), and JP-A-58-21601 (applicant: stock) (Hakugen Co., Ltd.) and the like describe a formulation that releases a drug into the air by slight heating.

[0003]

However, in order to produce a pesticidal agent that can be used at any place, which is now required, the above-mentioned known technique alone is not enough.
Because it is necessary to reduce the size and weight of the preparation in order to be able to use it in any place, energy efficiency is indispensable for realizing it. However, in the above-mentioned known technology, the introduction of a system is the center, and in addition to the proposal of a honeycomb structure that increases the surface area of a drug carrier, a comprehensive transpiration promotion method that leads to downsizing of a formulation and energy efficiency is achieved. There is very little mention in perspective. Furthermore, miniaturization of the preparation or the device using it
In order to improve efficiency, the selection of a suitable effective principal component is the most important, but most prior arts do not specify it. Accordingly, an object of the present invention is to provide a method for controlling pests that releases a transpirable drug with low energy, taking into account the compactness and weight of the preparation including energy efficiency.

BEST MODE FOR CARRYING OUT THE INVENTION According to the study of the present inventors, when an ester compound represented by the general formula 2 (see paragraph 0004) is used as an effective main component, it has a high vapor pressure and mainly High control activity against flying insect pests
In addition to being effective in a small amount, it is possible to exhibit high effects in a small area due to the physical properties that easily evaporate due to the high vapor pressure. It has been found that it is comprehensively effective in terms of conversion. Table 1 shows examples of the compound represented by the general formula (2) together with the compound numbers.
It goes without saying that the compound represented by is not limited to these examples.

[Table 1] As a preferred embodiment of the flying pest control method according to the present invention, from the viewpoint of the transpiration method, an example using a fan-type diffusion device, an example using natural transpiration, and an example using a heating transpiration device are considered, and these will be described in detail below. I do.

[0006] 1. Example using fan-type diffuser 1-1. Fan-type diffuser The fan-type diffuser has an air flow path and air blowing means through which air flows in the order of an intake port, a ventilation section, and an exhaust port, and has a carrier capable of carrying a medicine in the air flow path. An apparatus for diffusing a drug carried on a carrier into the air by an air flow generated in an air flow path due to the operation of the means can be given. More specifically, the apparatus has a blower for sucking air into the apparatus from the outside or a blower for discharging air from the apparatus to the outside. By operating the blower, air is supplied from the outside to the inside of the apparatus. The air is sucked and discharged from the exhaust port through the blower. Then, when the air flow generated by these comes into contact with the carrier, the carried drug is discharged to the outside through the exhaust port together with the air flow. Further, it is also preferable to employ a method in which the peripheral portion of the carrier is brought into a reduced pressure state with the air flow generated by the device to promote the evaporation of the drug. A device that generates a gas flow by the carrier itself is also useful in practicing the present invention. The shape of the driven carrier is preferably, for example, a fan.

[0007] There are various means for holding the volatile chemicals in the fan, and there are roughly two types: (1) a method in which the fan directly holds the volatile chemical, and (2) a method in which the fan holds it indirectly. In the method of (1), (a) the fan itself is composed of an oil-absorbing material (eg, resin) mixed with a volatile agent, and (b) the entire fan or an inner layer close to the surface thereof is made of a porous oil-absorbing material. It is possible to take a means of holding the inside of the fan, for example, by impregnating the volatile oil absorbing material portion with the volatile agent, and (c) containing the volatile agent on the fan surface. Means for holding the fan on the surface of the fan, such as applying a liquid, can be taken. In the method of (2), (a) a fan in which a volatile chemical is sealed is held or stored in the fan itself, (b)
Means such as supporting the oil absorbing material piece containing or impregnated with the volatile agent on the surface of the fan, and (c) fixing the fan with the volatile agent encapsulated on the surface of the fan can be used. When the volatile chemical held by the fan has been consumed as described above, it is necessary to replenish the volatile chemical in order to use it continuously. Among the methods (1), (a) In ()), the fan itself is replaced, and in the impregnation types (b) and (c), the volatile agent may be supplied by impregnation with a solution. In the method (2), (a),
In (c), it is only necessary to replace the one in which the volatile agent is sealed, and in (b), the oil-absorbing material piece may be replaced.

1-2. Driving means of the fan The driving means of the fan is preferably an electric motor or the like, and when considered for use in a normal room or the like, can be driven by obtaining power from a current plug or the like by a storage battery or a cord such as a dry battery or a solar battery. Things are suitable. In addition, there is no problem even if the driving means such as a mainspring is used. As the shape of the fan, a centrifugal fan is generally used, and examples thereof include a screw type or a propeller type, a water wheel type, and a rotary fan type. As one means for adjusting the amount of the chemical vaporized into the air, it is possible to make these fans have a strong blowing action, such as a screw type or a propeller type. In addition, by providing an opening in each blade forming the fan, the blowing action can be further enhanced. A sirocco fan is suitable as the shape of these fans. At this time, the number of rotations of the fan is, for example, about 500 to 1500 rpm.

1-3. Carrier The carrier preferably has a honeycomb-like, scaly-like, lattice-like, net-like, or granular-like structure in that it has a simple structure and high air permeability. The carrier only needs to have a gas permeability of usually 0.1 liter / sec or more in gas permeability. Examples of the material include inorganic and organic molding materials. Examples of the molded material include papers (filter paper, filter paper, and the like).
Pulp, cardboard, etc.), resins (polyethylene, polypropylene, polyvinyl chloride, highly oil-absorbing polymer, etc.), ceramics, glass fiber, carbon fiber, chemical fiber (polyester, nylon, acrylic, vinylon, polyethylene, polypropylene, etc.) , Natural fibers (cotton, silk, wool, hemp, etc.), glass fibers, carbon fibers, chemical fibers, non-woven fabrics of natural fibers and the like, porous glass materials, wire mesh and the like. The carrier containing the pest controlling component of the present invention is held on these carriers, and one or a combination of two or more thereof can be used in an arbitrary shape. When using a carrier for adsorption (auxiliary material for holding the drug on the carrier),
Examples of the carrier for adsorption include gelling substances (agar, carrageenan, starch, gelatin, alginic acid, etc.) and plasticized polymer substances. When plasticizing a polymer substance, for example, dioctyl phthalate is used.

1-4. Transpiration aids, etc. Adamantane, cyclododecane,
By adding a sublimable substance such as cyclodecane, norbornane, trimethylnorbonnan, naphthalene, camphor, etc., the transpiration effect can be further enhanced. Also,
α- [2- (2-butoxyethoxy) ethoxy] -4,
5 methylenedioxy-2-propyltoluene (piperonylbutoxide), N- (2-ethylhexyl) bicyclo [2,2,1] hept-5-ene-2,3-dicarboximide (MGK-264), octachlorodiisopropyl Other pyrethroid-based compounds such as ether (S-421) and sinepirin 500 can be used by mixing with known synergists as active ingredients. In addition, light,
The effect can be stabilized by adding and using an antioxidant or an ultraviolet absorber in order to enhance the stability against heat, oxidation and the like. Examples of the antioxidant include 2'-methylenebis (6-tert-butyl-4-ethylphenol), 2,6-di-tert-butyl-4-
Methylphenol (BHT), 2,6-di-tert-
Butylphenol 2,2'-methylenebis (6-te
rt-butyl-4-methylphenol), 4,4'-methylenebis (2,6-di-tert-butylphenol), 4,4'-butylidenebis (6-tert-butyl-3-methylphenol), 4,4 '-Thiobis (6
-Tert-butyl-3-methylphenol) and dibutylhydroxynone (DBH). Examples of the ultraviolet absorber include phenol derivatives such as BHT, bisphenol derivatives or phenol-α-naphthylamine, and condensation of phenetidine with acetone. And benzophenone-based compounds. When a medicine is absorbed and held in the holding material and a gas such as air is sent and volatilized, an indicator can be used directly or indirectly to know the medicine remaining in the medicine holding material. In order to have an indicator function, for example, to change the color of the carrier, allylaminoanthraquinone, 1,4-diisopropylaminoanthraquinone,
Dyes such as 1,4-diaminoanthraquinone, 1,4-dibutylaminoanthraquinone and 1-amino-4-anilinoanthraquinone can be used.

A method of determining the end point using an electron donating color compound can also be used. It consists of an electron-donating color-forming compound, a developer and a desensitizer. The chemical reaction of these compounds changes the color of the treated carrier with time, so that a combination with the above-mentioned agent is prepared. Thereby, it becomes effective in determining the end point at the time of use. Known compounds can be appropriately used as the compounds constituting these variable color dyes. For example, examples of the electron donating color compound include heat-sensitive pressure-sensitive dyes such as triphenylmethane-phthalides, fluorans, phenothiazones, indolylphthalides, spiropyrans, and rhodamine lactams. Examples of the developer include phenyl salicylate, p-cresol, propyl p-hydroxybenzoate, butylhydroxyanisole, methyl gallate, 2,2-bis (4'-hydroxyphenyl) propane, and the like. And as the desensitizer, ketones,
Examples include ethers, esters, alcohols, amines, and hydrocarbons.

Further, a fragrance or the like for the evaporation composition may be added or mixed. Further, in a case where the medicine is stored in a liquid bottle as a liquid, the medicine is supplied to the outside of the bottle while being absorbed by the holding material, and the gas is supplied to the holding material portion outside the bottle to be volatilized. It is sufficient to be able to confirm the change in the amount, and it is not necessary to use an indicator. As a method for retaining the agent (such as a pest control component) of the present invention on a carrier, the carrier may be coated with the agent in a liquid such as drop coating, impregnation coating, spray coating, liquid printing, brushing or the like, or a carrier. When the composition to be used is not liquid, or when a solvent is not used, it can be applied by kneading, coating, printing, or the like. In addition, when the drug is applied to the carrier as described above, the drug can be applied to the entire surface of the carrier, or can be applied to a portion such as a dot, one surface, or a pattern. In some cases, the medicine is stored in a liquid bottle and supplied to the vaporizing part via a porous medicine holding material. When the drug of the present invention is applied to a carrier, as an additive for lowering the viscosity of a liquid drug, for example, to facilitate impregnation of the drug into the carrier, isopropyl myristate, isopropyl palmitate, hexyl laurate and the like Organic solvents such as fatty acid esters, isopropyl alcohol, polyethylene glycol and deodorized kerosene can be used if necessary. The amount of the above-mentioned pest controlling component and / or various chemicals retained in the carrier is not particularly limited. For example, when the above-mentioned chemicals (such as pest controlling components) are contained in an oil-absorbing material (for example, paper), the oil-absorbing material is used. 50mg / g to 1000mg / g drug in
, Preferably from 100 mg / g to 700 mg / g
Range. This amount should be at least 0.1 mg / hr
Can be maintained up to the saturated impregnation amount with reference to the volatilization amount.

3. Example Using Heat Evaporation Apparatus Next, a dosage form for releasing the drug used in the present invention into the air by slightly heating at 70 ° C. or lower will be described. The reason why the micro heating of 70 ° C. or less was selected as the energy source is as follows.
It is a range that can be obtained without using AC power,
As a result, it is possible to obtain a free formulation that does not limit the place of use. At this time, the high vapor pressure and high activity characteristics of the drug of the present invention are advantageous in that energy can be efficiently used. Specific examples of the heat source include a method using the heat of a disposable body warmer, a method in which a PTC element is heated by a battery, and a method of burning petroleum benzene and flammable gas. Among them, the method using a disposable body warmer is an old known technique and can be easily used.

The heat generation method of the disposable body warmer is a method in which the heat of oxidation by the oxidation reaction is used as a heat source. As its composition, metallic iron is a main component, and moisture is indispensable for the oxidation of iron, and there are various methods for separating this moisture from iron until use in one bag, For example, water is put in a bag, sealed and broken at the time of use, a method of retaining water as silicic acid and / or sodium silicate hydrous salt, and a bag of activated carbon or diatomaceous earth impregnated with water is given to the bag. There is a method of separating it from metallic iron (iron powder). In any case, when used, the composition containing iron and water and other auxiliary agents such as salt, activated carbon, diatomaceous earth, etc. is supplied to oxygen (air) at an appropriate temperature of 50 kg as a warmer. ~ 7
It generates heat at 0 ° C. The exothermic temperature can be adjusted within a certain range depending on the composition and the supply amount of oxygen (air) essential for the oxidation reaction. That is, for example, if the air hole is increased so as to increase the air supply, the temperature increases, but the duration of the temperature decreases. Conversely, if the supply amount of air is reduced, the temperature can be kept low for a long time.

In the case of the present agent type, the above-mentioned known compounds can be used as an end point indicator, a synergist, an antioxidant, an ultraviolet absorber and a viscosity reducing agent to be added together with the drug. As the drug carrier used in the present dosage form, it is preferable to use carrier properties suitable for the above-mentioned spontaneous evaporation method.
