Description
Technical Field
The present invention relates to a method for controlling crawling insects such as Cimex lectularius using a metered dose type aerosol and an aerosol for controlling crawling insects such as Cimex lectularius.
Background
In recent years, the spread of cimex fasciatus has become a social problem in some hotels or hotels, and urgent countermeasures are being sought. As a type of insecticide to be applied to a place or a route where warm-banded bugs inhabit, such as warm-banded bugs that linger on floors and walls and remain in crevices, there have been typical (1) fumigants, (2) full-volume aerosol spray type and (3) aerosol spray type, which have characteristics in terms of formulation.
(1) Fumigant or (2) aerosol spray-type is a category of medicine in which a medicine is sprayed into every corner of a room, the room is sealed for a predetermined time, and the medicine concentration is increased, and a person cannot enter the room during the time. Such a preparation is characterized by so-called space treatment in which the sprayed chemical exhibits a high effect of repelling the warm-blooded bed bugs in the entire treatment space. However, such a preparation is not easy and often used because it requires maintenance of electric appliances and tableware before disposal, requires a cleaning operation of spraying sediments after disposal, and requires special attention to safety of chemicals.
On the other hand, the ease of use of the topically treated (3) coating-type aerosol, which is mostly a quasi-drug having a mild action on the human body, was evaluated as an advantage. As the coating type aerosol, for example, it is known that a noxious bed bug can be controlled by blending an insect pest control component with a specific saturated aliphatic hydrocarbon (for example, see patent document 1).
Further, as a method for repelling crawling insects with a smaller amount of a chemical agent than (1) a fumigant or (2) a full-injection aerosol, there are known: a method for repelling crawling pests in which an insecticide liquid containing an insecticide component and a solvent is sprayed by a piezoelectric sprayer in a small amount of time (see, for example, patent document 2). The method for exterminating vermin of patent document 2 is capable of exterminating crawling vermin by continuously floating fine particles of an insecticide liquid having a small particle size in a space such as an indoor space or a housing space.

Disclosure of Invention
Problems to be solved by the invention
However, the coating type aerosol of patent document 1 is not a space treatment such as (1) a fumigant or (2) a full-volume spray type aerosol, but a so-called local treatment which exerts a repellent effect on warm-blooded bed bugs only at the site where the chemical is treated, and therefore the contact efficiency between the chemical and the warm-blooded bed bugs is inferior to that of (1) the fumigant or (2) the full-volume spray type aerosol, and it is not always possible to provide a highly efficient repellent method.
The method for repelling crawling insects of patent document 2 proposes that cockroaches be repelled by spreading a small amount of chemical agent in a space for a long time, as in the case of liquid electric mosquito coils, but since cockroaches having strong resistance to the chemical agent are targeted, a strong insecticidal component must be used, and thus, the safety of the cockroaches against human bodies cannot be avoided. Further, the method of patent document 2 does not necessarily allow effective removal of warm-banded bugs, which are different from cockroaches in ecology and habit.
As described above, there has been a demand for developing a crawling pest control agent which is a quasi-drug suitable for easy use while performing space treatment with excellent contact efficiency between a drug and cimex felis, but there has not been put to practical use.
The present invention has been made in view of the above problems, and an object of the present invention is to provide: a method for effectively controlling crawling pests, especially crawling pests of cimex labyrinthusa, having a habit of hiding in crevices by using a quantitative spray type aerosol; and an aerosol for controlling crawling pests.

Detailed Description
Hereinafter, the method for controlling crawling pests and the aerosol for controlling crawling pests of the present invention will be described. However, the present invention is not intended to be limited to the configurations described below.
[ compounding of an Aerosol for controlling crawling pests ]
The aerosol for controlling crawling pests of the present invention is a metered dose aerosol for use in controlling crawling pests such as cimex labyrinthusa by space treatment, and is configured as an aerosol liquid containing a crawling pest control component and a solvent, and a propellant filled in an aerosol container provided with a metered dose injection valve. Here, the "spatial processing" in the present invention means: by spreading the crawling insect pest control component widely in the treatment space, the treatment of crawling insect pests such as warm-banded bugs can be controlled in the whole treatment space. In the space treatment, a high control effect can be expected because the contact efficiency between the control ingredient and the crawling insect is excellent as compared with the local treatment in which the control ingredient is locally treated and the crawling insect is controlled only at the position where the control ingredient has been treated. In the method for controlling crawling insect pests of the present invention, since the aerosol of the quantitative injection type is sprayed toward the space in the room, the method can exert practically sufficient control effect on crawling insect pests such as cimex lectularis, and the effect on the human body is alleviated because the amount of the chemical agent is smaller than that of the fumigant or the aerosol of the full injection type. In the present specification, the repellent effect is referred to as a control effect, including a repellent effect in addition to a repellent effect based on a knock down (knock down) effect or a lethal effect. If the repellent effect is sufficient although the repellent effect is low, the control is often achieved in practice.
< Aerosol collagen liquid >
A crawling pest control component, which is one of the main components of an aerosol liquid, comprises a 2,3,5, 6-tetrafluorobenzyl ester compound having a common skeleton represented by general formula (I) and a 3-phenoxybenzyl ester compound having a common skeleton represented by general formula (II).
[ solution 5]
[ wherein X represents a hydrogen atom, a methyl group or a methoxymethyl group, and R 1 And R 2 Each represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 3 carbon atoms, a haloalkyl group having 1 to 3 carbon atoms or a cyano group.]
[ solution 6]
[ wherein Y represents a hydrogen atom or a cyano group, Z represents a hydrogen atom or a fluorine atom, R 3 And R 4 Each represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 3 carbon atoms or a haloalkyl group having 1 to 3 carbon atoms.]
When the aerosol for controlling crawling pests of the present invention is sprayed in a predetermined amount in a treatment space in a house, the sprayed particles settle on the floor surface mainly as adhesive particles, and different compounds having a common skeleton, such as a 2,3,5, 6-tetrafluorobenzyl ester compound represented by general formula (I) and a 3-phenoxybenzyl ester compound represented by general formula (II), are used in combination as a crawling pest control component, whereby the control effect on crawling pests such as temperate bugs sticking to the floor or wall can be improved.
Examples of the 2,3,5, 6-tetrafluorobenzyl ester compound represented by the general formula (I) include methofluthrin (Metofluthrin), Transfluthrin (Transfluthrin), proffluthrin (proffluthrin), momfluthrin (japanese: モンフルオロトリン), Dimefluthrin (Dimefluthrin), Tefluthrin (Tefluthrin), heptafluthrin (heptafluthrin), and chlorofluoroththrin (meperfluthrin), and among these, methofluthrin, Transfluthrin, and proffluthrin are preferable in view of volatility (vapor pressure), stability, and basic insecticidal efficacy. The above-mentioned 2,3,5, 6-tetrafluorobenzyl ester compounds can be used singly or in combination of two or more. It is to be noted that, in the acid portion and the alcohol portion of the 2,3,5, 6-tetrafluorobenzyl ester compound, when an optical isomer based on asymmetric carbon and a geometric isomer based on a double bond are present, each of them or an arbitrary mixture thereof is also included in the present invention.
Examples of the 3-phenoxybenzyl ester compound represented by the general formula (II) include phenothrin (phenothrin), Cyphenothrin (Cyphenothrin), permethrin (permethrin), Cypermethrin (Cypermethrin), Deltamethrin (Deltamethrin), cyhalothrin (cyhalothrin), and cyfluthrin (cyfluthrin). Among these, phenothrin, permethrin and cypermethrin are preferable. The 3-phenoxybenzyl ester compounds mentioned above can be used singly or in combination of two or more kinds. It is to be noted that, in the acid moiety and the alcohol moiety of the 3-phenoxybenzyl ester compound, when there are optical isomers based on asymmetric carbon and geometric isomers based on double bond, each of them or an arbitrary mixture thereof is also included in the present invention.
The content of the crawling insect pest control component in the aerosol collagen solution of the 2,3,5, 6-tetrafluorobenzyl ester compound and the 3-phenoxybenzyl ester compound in total is preferably 30 to 75 w/v%. When the content of the crawling insect pest control component in the aerosol collagen liquid is in the above range, the spray particles are formed in a state optimal for controlling crawling insect pests such as warm-banded bugs when the aerosol is sprayed, and an appropriate control effect can be obtained. If the content of the crawling insect pest control component in the aerosol collagen liquid is less than 30 w/v%, the crawling insect pest control component released into the treatment space may be insufficient, and a sufficient control effect may not be obtained. If the content of the crawling insect pest control component in the aerosol collagen liquid exceeds 75 w/v%, the spray particles may not be formed in a state optimal for controlling crawling insect pests such as warm-banded bugs when the aerosol is sprayed.
Examples of the solvent as one of the main components of the aerosol collagen liquid include a lower alcohol having 2 to 3 carbon atoms, a hydrocarbon solvent (e.g., an n-alkane solvent and an isoparaffin solvent), a higher fatty acid ester having 16 to 20 carbon atoms, a glycol ether solvent having 3 to 10 carbon atoms, and a ketone solvent, and preferably a lower alcohol having 2 to 3 carbon atoms or a higher fatty acid ester having 16 to 20 carbon atoms is used. By using these solvents, the sprayed particles are likely to enter the slit after spraying, and excellent control effects can be exerted even against crawling pests such as warm-banded bugs which are latent in the slit. Examples of the lower alcohol having 2 to 3 carbon atoms include ethanol, 1-propanol, and 2-propanol, and examples of the higher fatty acid ester having 16 to 20 carbon atoms include isopropyl myristate, butyl myristate, and hexyl laurate. Among these, ethanol or isopropyl myristate is preferable from the viewpoint of being easily taken into the slit, and ethanol is more preferable from the viewpoint of being easily taken into the slit because the volatile particle diameter after spraying is easily reduced.
Aerosol collagen liquid was prepared as follows: wherein when the content of the 2,3,5, 6-tetrafluorobenzyl ester compound is a, the content of the 3-phenoxybenzyl ester compound is b, and the content of the solvent is c, δ defined by the following formula (1) satisfies 0.45 to 4.00,
δ＝b/(a+c)…(1)
the aerosol collagen liquid is preferably prepared so that the delta satisfies 0.45 to 3.20. δ obtained by the above formula (1) is a parameter indicating the weight ratio of the hardly volatile component (3-phenoxybenzyl ester compound) to the highly volatile component (2,3,5, 6-tetrafluorobenzyl ester compound and solvent) in the aerosol collagen liquid, and by combining the above specific crawling insect pest control component and solvent so that the value of δ is 0.45 to 4.00, crawling insect pests such as temperate bugs which reside in the gaps can be effectively controlled by unexpected synergistic effects of the components, in addition to crawling insect pests such as temperate bugs which reside in the floors and walls.
In addition to the above components, the aerosol raw liquid may be appropriately blended with: antifungal agents, antibacterial agents, bactericides, antiviral agents, aromatic agents, deodorants, stabilizers, antistatic agents, antifoaming agents, excipients and the like which are intended for fungi, viruses and the like. Examples of the antifungal agent, the antibacterial agent, the bactericidal agent, and the antiviral agent include: hinokitiol, 2-mercaptobenzothiazole, 2- (4-thiazolyl) benzimidazole, 5-chloro-2-methyl-4-isothiazolin-3-one, Triforine (Triforine), 3-methyl-4-isopropylphenol, o-phenylphenol and the like. Further, as the aromatic agent, there can be mentioned: orange oil, lemon oil, lavender oil, peppermint oil, eucalyptus oil, citronella oil, lime oil, grapefruit oil, jasmine oil, hinoki oil (Japanese: oil), green tea essential oil, limonene, α -pinene, linalool, geraniol, phenylethyl alcohol, amyl cinnamic aldehyde, cuminaldehyde, benzyl acetate and other fragrance components, fragrance components to which geraniol or geranial called "green fragrance" is added, and the like.
The aerosol for controlling crawling pests of the present invention may also be formulated in an aqueous form. In this case, the amount of water contained in the aerosol liquid is preferably about 5 to 50 v/v%, and a nonionic surfactant may be added as a solubilizing aid in an amount within a range not affecting the spray pattern of the spray particles. Examples of the nonionic surfactant include ethers such as polyoxyethylene alkyl ethers, polyoxyethylene alkylphenyl ethers, polyoxyethylene polyoxypropylene alkyl ethers, and polyoxyethylene alkylamino ethers, fatty acid esters such as polyethylene glycol fatty acid esters, polyoxyethylene sorbitan fatty acid esters, and polyoxyethylene glycerin fatty acid esters, polyoxyethylene styrenated phenols, and polyalkanolamides of fatty acids, and among these, ethers are preferred.
< propellant >
The propellant used in the aerosol for controlling crawling pests of the present invention includes liquefied gases such as Liquefied Petroleum Gas (LPG), dimethyl ether (DME) and hydrofluoroolefin, nitrogen gas, carbon dioxide gas, nitrous oxide and compressed air, and among these, liquefied gases are preferred. The above-mentioned propellants can be used singly or in a mixed state, but are easy to use by using LPG as a main component.
The aerosol for controlling crawling pests of the present invention is configured as follows: when the filling volume of the aerosol liquid filled in the sol container is L and the filling volume of the propellant is G, the following formula (2) is satisfied.
0.1≤L/(L+G)≤0.5…(2)
By satisfying the above formula (2), a sufficient amount of the crawling insect pest control component can be uniformly diffused to the floor surface, the wall surface, and the entire gap in the treatment space. If [ L/(L + G) ] is smaller than 0.1, that is, if a large amount of the propellant sealed in the aerosol container is used, the spray particles formed from the aerosol raw liquid to be sprayed may be made finer than necessary, and the amount of the pest control component adhering to the floor surface or wall surface may be insufficient. If [ L/(L + G) ] is larger than 0.5, that is, if the amount of the propellant sealed in the aerosol container is small, the spray particles may become large, and the arrival of the pest control component at the gap may become insufficient.
[ Aerosol spray nozzle for controlling crawling pests ]
The shape (cross-sectional shape) of the aerosol jet port for controlling crawling pests of the present invention is not particularly limited, and examples thereof include a polygon such as a circle and a quadrangle, an ellipse, and the like, and preferably a circle. Here, the orifice diameter means: when the shape of the jet orifice is an ellipse, the jet orifice has a major diameter of the ellipse; when the shape of the ejection opening is a polygonal shape, the ejection opening has a diameter of a circumscribed circle of the polygon. The opening area of the jet orifice is preferably 0.05-8.0 mm 2 More preferably 0.1 to 4.0mm 2 More preferably 0.2 to 3.0mm 2 . For example, when the number of the ejection openings is 1 and the shape of the ejection openings is circular, the size (ejection opening diameter) of the ejection openings is preferably 0.2mm or more, more preferably 0.3mm or more, and still more preferably 0.5mm or more. The nozzle diameter is preferably 3.0mm or less, more preferably 2.0mm or less, and still more preferably 1.8mm or less. When the diameter of the spray nozzle is 0.2 to 3.0mm, the size of the spray particles becomes appropriate, and a sufficient amount of the crawling insect pest control component reaches the slit, and crawling insect pests such as warm-zone bugs and the like which are latent in the slit can be suitably controlled.
The number of the injection ports of the aerosol for controlling reptile insect of the present invention may be 1, but may be 2 or more, but from the viewpoint of easy and low-cost production, the number of the injection ports is preferably 1.
The angle of elevation of the aerosol jet nozzle for controlling crawling pests of the present invention with respect to the jet nozzle of the horizontal plane is usually set to 0 to 60 °, preferably 10 to 60 °, and more preferably 15 to 50 °. If the angle of elevation of the ejection port with respect to the horizontal plane is in the above range, ejection failure is less likely to occur, and the aerosol liquid can be stably ejected. In addition, the elevation angle of the ejection port with respect to the horizontal plane of the nozzle or actuator having 2 ejection ports is defined as the elevation angle of the vertical bisector of the line segment connecting the centers of the ejection ports with respect to the horizontal plane. With respect to a nozzle or an actuator having 3 or more ejection ports, the elevation angle of the ejection ports with respect to the horizontal plane is determined as follows. In the case where the ejection port is present in the center of the ejection portion of the nozzle or the actuator, an angle of elevation of an orthogonal line passing through the center of the ejection port in the center thereof with respect to a horizontal plane is defined. In the case where no ejection port is present in the center of the ejection portion of the nozzle or the actuator, the angle of elevation of the orthogonal line passing through the centers of the circumscribed circles of the polygon connecting the centers of the ejection ports with respect to the horizontal plane is defined.
In the aerosol for controlling crawling pests of the present invention, the ejection force at a position 5cm away from the ejection orifice is preferably set to 3 to 50gf, more preferably 10 to 30 gf. When the injection force is in the range of 3 to 50gf, a sufficient amount of the crawling pest control component adheres to the floor surface and the wall surface, and the crawling pest control component reaches the gap of the treatment space, so that practically sufficient control effects are obtained for both crawling pests such as naematoloma japonicum which wanders on the floor surface and crawling pests such as naematoloma japonicum which are latent in the gap. In the present embodiment, the ejection force of the aerosol for controlling insect pests was measured by a digital force gauge (FGC-0.5, manufactured by Nissan electric products Co., Ltd.).
In the aerosol for controlling crawling pests of the present invention, the injection volume per one time of the fixed injection valve is preferably 0.1 to 5.0mL, more preferably 0.2 to 3.0mL, and still more preferably 0.2 to 1.0 mL. If the injection volume per one injection is 0.1 to 5.0mL, for example, the injection volume per one injection corresponds toThe room volume of 4.5-8 tatami is 18.8-33.3 m 3 (area 7.5 to 13.3 m) 2 And a height of 2.2 to 3.0m), the amount of the crawling pest control component to be released becomes appropriate by spraying the crawling pest control aerosol once to several times, and practically sufficient control effects are obtained for the crawling pests, particularly excellent control effects for temperate bugs, in the treatment space. Further, when the injection volume per injection is 0.1 to 5.0mL, the treatment frequency is sufficient for 1 time in 1 to 7 days.
In the aerosol for controlling crawling pests of the present invention, the shape of the nozzle, the container, and the like may be appropriately selected depending on the application, the purpose of use, and the like. For example, the container may be designed to be a desktop type container having a button to be pressed from above to eject the liquid and a nozzle directed obliquely upward, or a portable type container having a small size.

[ method for controlling crawling pests ]
The method for controlling crawling pests according to the present invention is a method for controlling crawling pests, comprising spraying a fixed-quantity-spraying aerosol comprising a specific crawling pest control component such as the crawling pest control aerosol of the present invention and a solvent toward a treatment space. When the fumigant or the full-volume spray type aerosol is used, the treatment space needs to be closed for 2 to 3 hours during the chemical treatment, and thus, people cannot enter the treatment space, and in addition, the cleaning work of spraying deposits is needed after the maintenance of electric appliances and tableware before the treatment. In contrast, in the method for controlling crawling pests according to the present invention, the crawling pest control component sprayed in the treatment space can be suppressed to a small amount by using a fixed-amount spray type aerosol. Therefore, according to the method for controlling crawling pests of the present invention, the preparation steps before treatment and the cleaning operation of the sprayed sediments after treatment, which are necessary in the case of fumigant or aerosol of full-volume spraying type, are not required. In addition, in the method for controlling crawling pests according to the present invention, since the space treatment is performed using the aerosol of the metered dose type, the treatment for controlling crawling pests can be safely performed without exiting from the indoor space which becomes the treatment space. As described above, the method for controlling crawling pests according to the present invention adopts a space treatment method having a higher control effect than the local treatment method, and provides convenience that cannot be expected from space treatment using a conventional fumigant or a full-volume aerosol.
In the method for controlling crawling pests of the present invention, when the aerosol for controlling crawling pests is sprayed indoors, the amount of the crawling pest control component released into the air is preferably 0.1 to 50mg/m 3 More preferably 0.5 to 50mg/m 3 . When the amount of the crawling pest control component released into the air is in the above range, the crawling pest control component has high safety even in a human environment, and can obtain an excellent control effect on crawling pests, particularly on temperate bedbugs. An aerosol for controlling crawling pests, comprising a fixed-volume injection valve having an injection volume per one time of 1.0 to 5.0mL, wherein the volume of a room corresponding to 4.5 to 8 tatami is 18.8 to 33.3m 3 (area 7.5 to 13.3 m) 2 And a height of 2.2 to 3.0m), the amount of the crawling pest control component released into the air is usually 0.1 to 50mg/m by one-time spraying in the case of carrying out the method for controlling crawling pests of the present invention 3 . In a treatment space of a house with a larger volume, the volume of the treatment space is matched so that the release amount of the crawling pest control component in the air is 0.1-50 mg/m 3 The same control effect can be obtained regardless of the size of the treatment space by performing the spraying a plurality of times. Even when an aerosol having a constant-volume injection valve with an injection volume per one time of less than 1.0mL, for example, 0.1 to 0.9mL, is used, the amount of the pest control component released in the air is controlled to be 0.1 to 50mg/m 3 Is adjusted appropriatelyThe number of spraying times is adjusted, so that excellent control effects on crawling pests, particularly on temperate bugs, can be obtained.
The method for controlling crawling pests of the present invention is preferably performed at a frequency of once every 1 to 7 days. As described above, according to the method for controlling crawling pests of the present invention, the crawling pest control component comprising the 2,3,5, 6-tetrafluorobenzyl ester compound and the 3-phenoxybenzyl ester compound and the solvent (preferably a lower alcohol having 2 to 3 carbon atoms or a higher fatty acid ester having 16 to 20 carbon atoms) are used in combination, and the synergistic effect of these components can further enhance the control effect on crawling pests, particularly on temperate bugs, and therefore, even if the application frequency is once for 1 to 7 days, a practically sufficient control effect can be expected for crawling pests, particularly an excellent control effect on temperate bugs. Thus, the method for controlling crawling pests of the present invention can reduce the frequency of application of the aerosol for controlling crawling pests.
In the method for controlling crawling pests according to the present invention, the aerosol for controlling crawling pests is preferably sprayed so that the spraying direction angle of the aerosol is 0 to 60 °, more preferably 30 to 60 °, relative to the horizontal plane. When the aerosol is ejected at an angle in the above range, the diffusion uniformity is excellent.
The type of crawling insect pest effective in the crawling insect pest control method of the present invention is not particularly limited. Examples of crawling pests include spider, cockroach, centipede, ant, millipede, continental groundsel, psyllid, pillworm, termite, caterpillar, mite, louse, tick, and cimex. Among these, the composition exhibits an excellent control effect on spider, cockroach, and cimex feldiana, and particularly exhibits an excellent control effect on cimex feldiana (bed bugs), cimex taiwanensis (tropical bugs), and the like.
[ examples ]
In order to verify the effects of the present invention, an aerosol for controlling crawling insect pests having the characteristic configuration of the present invention was prepared (examples 1 to 17), and the effects of repelling cimex feldianus that is sticking to the floor and cimex feldianus that is standing in a gap were examined. For comparison, an aerosol for controlling crawling pests not having the characteristic configuration of the present invention was prepared (comparative examples 1 to 8), and the same study was performed.
[ example 1]
Aerosol solution was prepared by dissolving 0.168g (0.56 w/v%) of metofluthrin as a 2,3,5, 6-tetrafluorobenzyl ester compound, Compound A, and 13.20g (44 w/v%) of phenothrin as a 3-phenoxybenzyl ester compound, Compound B, in 13.76g of ethanol as a solvent. The value of δ of the aerosol collagen liquid calculated by the above formula (1) was 0.948. This aerosol stock solution (30 mL) and liquefied petroleum gas (70 mL) were pressurized and filled in an aerosol container equipped with a quantitative injection valve (injection volume per one injection: 0.4mL), to obtain an aerosol for controlling crawling insects used in example 1. The aerosol for controlling crawling pests had a volume ratio [ L/(L + G) ] of 0.3 calculated from the filling volume L of the aerosol liquid and the filling volume G of the propellant, and a jetting force of 14gf at a jetting distance of 5 cm.
[ example 2]
Aerosol solution was prepared by dissolving 0.168g (0.56 w/v%) of metofluthrin as a 2,3,5, 6-tetrafluorobenzyl ester compound, Compound A, and 13.20g (44 w/v%) of phenothrin as a 3-phenoxybenzyl ester compound, Compound B, in 13.76g of ethanol as a solvent. The value of δ of the aerosol collagen liquid calculated by the above formula (1) was 0.948. This aerosol stock solution (30 mL) and liquefied petroleum gas (70 mL) were pressurized and filled in an aerosol container equipped with a constant volume injection valve (0.2mL per injection volume), to obtain an aerosol for controlling crawling insects used in example 2. The aerosol for controlling crawling pests has a volume ratio [ L/(L + G) ] calculated from the filling volume L of the aerosol liquid and the filling volume G of the propellant of 0.3, and a jetting force of 5gf at a jetting distance of 5 cm.
[ example 3]
Aerosol solution was prepared by dissolving 0.168g (0.56 w/v%) of metofluthrin as a 2,3,5, 6-tetrafluorobenzyl ester compound, Compound A, and 13.20g (44 w/v%) of phenothrin as a 3-phenoxybenzyl ester compound, Compound B, in 13.76g of ethanol as a solvent. The value of δ of the aerosol collagen liquid calculated by the above formula (1) was 0.948. This aerosol stock solution (30 mL) and liquefied petroleum gas (70 mL) were pressurized and filled in an aerosol container equipped with a constant volume injection valve (1.0 mL per injection volume), to obtain an aerosol for controlling crawling insects used in example 3. The aerosol for controlling crawling pests had a volume ratio [ L/(L + G) ] of 0.3 calculated from the filling volume L of the aerosol liquid and the filling volume G of the propellant, and a jet force of 27gf at a jet distance of 5 cm.
Examples 4 to 17 and comparative examples 1 to 8
Various aerosols for controlling crawling pests were prepared according to the procedure of example 1 with the formulations shown in tables 1 and 2. Each of the crawling insect pest control aerosols was prepared so that the ejection force at an ejection distance of 5cm was 14 gf.
In examples 1 to 17 and comparative examples 1 to 8, tests were conducted to confirm (1) the effect of repelling nauplius chinensis bugs that wander to the floor and (2) the effect of repelling nauplius chinensis bugs that have remained in crevices. The test results are shown in table 3.
(1) Expelling effect on temperate bugs lingering on floors
A total of 4 glass plates of 20X 20cm were placed in a closed volume of 25m 3 Room (corresponding to 6 tatami room, area 10 m) 2 ) In order to prevent escape, plastic rings of about 10cm diameter coated with vaseline were placed on each glass plate at the 4 corners, and a predetermined insect to be tested (warm-banded bugs: 5) to wander freely. In examples 1 and 4 to 17 and comparative examples 1 to 8, the test aerosol was sprayed in a slightly upward direction at the center of the room at 4 corners with a slight downward inclination of 0.4mL each time. In example 2, the test aerosol was directed slightly obliquely upward at 4 in the center of the room by 0.2mL each timeCorner spray 6 down. In example 3, the test aerosol was sprayed 1 lower at 1.0mL in the center of the room, slightly obliquely upward. After the spray was left for 24 hours and exposed to the chemical, the glass plate was transferred to another room together with the ring containing the test insects, and the bait was given, and further after 24 hours, the lethality of the test insects was determined.
(2) Expelling effect on temperate bugs hidden in gaps
A trough (width 35cm, depth 28cm, height 6cm) coated with Vaseline for escape prevention was set at a closed volume of 25m 3 Room (corresponding to a 6-tatami room, area 10 m) 2 ) 5 warm-banded bugs were placed in each tank, and a wooden shelter (20 cm wide, 10cm deep, 1cm high, open only in the front) was left standing to allow the warm-banded bugs to remain latent. In examples 1 and 4 to 17 and comparative examples 1 to 8, the test aerosol was sprayed in a slightly upward direction at the center of the room at 4 corners with a slight downward inclination of 0.4mL each time. In example 2, the test aerosol was sprayed in the center of the room at a slightly upward angle of 0.2mL each time toward 4 corners 6. In example 3, the test aerosol was sprayed 1 lower at 1.0mL in the center of the room, slightly obliquely upward. After the spraying, the test insects were left for 30 minutes to be exposed to the chemical, and then the tank was transferred to another room together with the wooden shelter in which the test insects were latent, and the bait was given, and the lethality of the test insects was determined after 5 days.
[ Table 3]
As a result of the test, in any of examples 1 to 17, the mortality rate of the nauplii which linger on the floor was 85% or more, and the mortality rate of the nauplii which were hidden in the gap was 80% or more. It was confirmed that by carrying out the method for controlling crawling pests of the present invention, both the control effect on nauplius melastoma dorsalis on the floor and the control effect on nauplius melastoma dorsalis latent in crevices are obtained at high levels. The aerosol for controlling reptile pests used in examples 1 and 4 to 17 was effective about 60 times when 1.6mL (0.4mL × 4) was used in 1 treatment. The aerosol for controlling crawling insect pests used in example 2 was effective about 80 times when 1.2mL (0.2mL × 6) was used in 1 treatment. The aerosol for controlling crawling insect pests used in example 3 was effective about 100 times when 1.0mL was used in 1 treatment.
On the other hand, as in comparative examples 1 and 2, if the value of δ calculated by the above formula (1) is out of the range of 0.45 to 4.00, a sufficient control effect cannot be obtained for any of the nauplius gifuensis nakai that wanders to the floor and nauplius gifuensis nauplii that are caught in crevices. From this fact, it is considered that when the value of δ is out of the range of 0.45 to 4.00, the synergistic effect of the solvent obtained by using 2,3,5, 6-tetrafluorobenzyl ester compound, 3-phenoxybenzyl ester compound, and lower alcohol having 2 to 3 carbon atoms or higher fatty acid ester having 16 to 20 carbon atoms in combination cannot be sufficiently exhibited.
In comparative example 3 in which enynethirin (Empenthrin) different from the 2,3,5, 6-tetrafluorobenzyl ester compound was used as the compound a, the control effect against warm-zone bugs which are latent in the crevices in particular was not sufficient. In comparative example 4 in which a different propargyl ester (imiproxrin) from the 3-phenoxybenzyl ester compound was used as compound B, the control effect was hardly observed for either of naematoloma cruentum and naematoloma sculatum residing in the gaps. In addition, in comparative example 5 in which only the 3-phenoxybenzyl ester compound as the compound B was blended as the crawling insect pest control component, the control effect against the temperate bugs which are latent in the crevices in particular was not sufficient. In comparative example 6 in which only the 2,3,5, 6-tetrafluorobenzyl ester compound as compound a was added as the crawling insect pest control component, the control effect was hardly confirmed for either of naematoloma fasciatus sticking to the floor and naematoloma fasciatus standing in crevices. Thus, in order to obtain a sufficient control effect against both naematoloma fasciatus sticking to the floor and naematoloma fasciatus standing in crevices, it is considered that a plurality of types of crawling insect pest control components are used in combination to achieve the effect: it is not sufficient to use only a plurality of types of crawling insect pest control components in combination, and it is necessary to use a combination of the specific 2,3,5, 6-tetrafluorobenzyl ester compound and 3-phenoxybenzyl ester compound as defined in the present invention.
In comparative example 7 in which the volume ratio [ L/(L + G) ] calculated from the filling volume L of the aerosol liquid and the filling volume G of the propellant was 0.6 and the filling volume of the aerosol liquid was too large, the control effect against the cimex felina staying on the floor was high, but the control effect against the cimex felina staying in the crevice was not sufficient. This is considered to be: since the amount of the aerosol collagen liquid filled is large, the spray particles are large and the spray particles rapidly and excessively settle on the floor surface, and the spray particles do not sufficiently reach the crevices, and the control effect on the warm-zone bed bugs which are latent in the crevices is reduced. On the other hand, in comparative example 8 in which the volume ratio [ L/(L + G) ] was 0.05 and the filling volume of the propellant was too large, the control effect against naematoloma japonicum which was latent in the gap was high, but the control effect against naematoloma japonicum which was stuck to the floor was not sufficient. The reason is considered to be that: since the amount of the propellant is large, the spray particles become too small and easily reach the gaps, but since the spray particles that do not reach the gaps do not settle on the floor surface but remain in the air for a long time, the pest control component attached to the floor surface is insufficient.
[ reference example 1]
In order to confirm the effect of the aerosol for controlling reptiles of the present invention when a solvent other than the solvents used in the examples (ethanol, 2-propanol, isopropyl myristate) was used, Isopar M, which is an isoparaffin-based solvent, was used as the solvent in place of 2-propanol in the formulation of example 7 to prepare an aerosol for controlling reptiles (reference example 1). The reptile insect-controlling aerosol of reference example 1 had a δ value calculated from the above formula (1) of 2.28, a volume ratio [ L/(L + G) ] of 0.3 calculated from the filling volume L of the aerosol liquid and the filling volume G of the propellant, and a jetting force of 14gf at a jetting distance of 5 cm.
In the aerosol for controlling crawling pests of reference example 1, when the same repelling effect confirmation test as in the above example was performed, the mortality rate of bed bugs sticking to the floor (after 1 day) was 80%, but the mortality rate of bed bugs sticking to the gaps (after 5 days) stayed at 15%, and the control effect on bed bugs sticking to the gaps was lower than that on bed bugs sticking to the floor. The reason is considered to be that: after spraying, the sprayed particles did not reach the crevices sufficiently, and the control effect (synergistic effect) of the specific 2,3,5, 6-tetrafluorobenzyl ester compound and 3-phenoxybenzyl ester compound specified in the present invention was not exhibited to the extent of the examples against the temperate bedbugs which are latent in the crevices.
