Description

Aerosol for preventing and eliminating pests and method for preventing and eliminating pests

The present invention relates to a pest control aerosol formed by filling an aerosol stock solution containing insecticidal components and a solvent, and a propellant in an aerosol container equipped with a quantitative injection valve, and a pest control aerosol using the pest control aerosol method.

Cockroaches, bed bugs (Cimex lectularius) and other creeping pests that linger on the floor or wall are used as insecticides that are applied to the places or paths where the creeping pests inhabit. In the past, representative examples include (1) aerosols, ( 2) Full-volume spray type aerosol, (3) coating type aerosol and (4) bait agent, each has its advantages in dosage form.

(1) Aerosol or (2) Full-volume jet aerosol is a method of dispersing the medicine to every corner of the room in one breath, sealing the room for a specified time, and increasing the concentration of the medicine. category. These preparations are characterized by the so-called spatial treatment, which exerts a high repellent effect on creeping pests in the entire treatment space by the released agent. However, these preparations require the maintenance of electrical appliances or tableware before treatment, and the cleaning work of spraying sediments after treatment becomes necessary, and further requires special attention to the safety of the drugs. It is difficult to say that it is easy and convenient. The dosage form that can be used frequently.

On the other hand, (3) coated aerosols for local surface treatment or (4) bait for spot treatments are equivalent to quasi-drug products that relax the effect on the human body, and (1) aerosol or (2) Although the full-volume jet aerosol is relatively easy to use, because it is not a space treatment, the contact efficiency between the agent and the pests is deteriorated, and it is not always possible to provide an efficient repellent method.

In this way, it has been considered difficult in the past to develop a creeping pest control agent that is equivalent to a quasi-drug, although it is a space treatment.

The inventors first aimed at the development of space treatment agents, which are equivalent to quasi-medicinal insecticides for creeping pests, rather than formulations such as (1) aerosols or (2) full-volume spray aerosols. If you use quantitative sprays The type of aerosol, sprayed, will exert a practically sufficient control effect, and it is a highly safe preparation that can be used even in a human situation. As a result, invented a method for controlling not only creeping pests but also flying pests on the day of spraying (refer to Patent Document 1). [Prior Technical Literature] [Patent Literature]

[The problem to be solved by the invention]

The method for controlling pests and mites of Patent Document 1 regards as a problem not only crawling pests but also flying pests, achieving a practical repellent effect, and is highly practical. In this method for controlling pests and mites, as the spraying characteristics of aerosols, spray particles after spraying are formed on floating particles, adherent particles related to adhesion to the wall surface, etc., and sedimentation to the floor surface. The inventors of the present inventors have made diligent research to further improve the control effect of cockroaches and the like among the quantitative spray type aerosols used in space treatment and creeping pests.

In the research, it is considered that it is important to deal with space and creeping pests. In order to improve the control effect especially against cockroaches, etc., the spray characteristics of the adhering particles are compared with the spray characteristics of Patent Document 1. For adhesion, it is more important to increase the ratio of particles settled on the floor surface, and furthermore, it is important to uniformly adhere to the entire floor surface.

After spraying, the aerosol is affected by the vaporization heat of the propellant, which reduces the temperature of the aerosol stock solution. The inventors found that the viscosity change at this temperature, that is, the viscosity ratio of the temperature of the aerosol stock solution, is an important factor in determining the behavior of the sedimentation of the adherent particles. Repeated trial and error experiments As a result, by specifying the ratio of the specific gravity of the aforementioned aerosol stock solution to the viscosity by temperature in the most appropriate range, the present invention was finally completed.

The object of the present invention is to provide an aerosol for controlling pests, which is a quantitative spray type aerosol used in space treatment to improve the control effect on creeping pests, and further, to provide a pest control aerosol using the aerosol for controlling pests method. [Means to solve the problem]

The characteristic structure of the aerosol for pest control of the present invention to solve the above-mentioned problems is to combine an aerosol stock solution containing an insecticidal component and a solvent with ^{a vapor pressure of less than 1.5×10 -3 mmHg at 30°C, and a spray} An aerosol for controlling pests, filled in an aerosol container equipped with a quantitative injection valve, characterized in that the aerosol stock solution has a specific gravity of 0.82 to 1.25 at 20°C and a viscosity η ₁₀ of 3.2 to 60.0 at 10°C. mPa · s, a viscosity at 30 deg.] C at a viscosity ratio η ₃₀ to 10 deg.] C of η ₁₀ η ₃₀ / η ₁₀ from 0.40 to 0.92, each of the lines followed by quantitative injection valve injection capacity of 0.1 ~ 3.0mL.

According to the present configuration of controlling pests aerosol, with the aerosol 20 ℃ liquid specific gravity, the viscosity at 10 deg.] C to ₁₀ [eta], and the viscosity η _{30 30} ℃ and [eta] is the ratio η ₃₀ at ₁₀ deg.] C viscosity of 10 / η ₁₀ is in the above range. After the aerosol is sprayed, the viscosity of the aerosol stock solution will not change rapidly due to the temperature change caused by the heat of vaporization of the propellant, and the spray particles will be properly diffused while rapidly sinking . As a result, the insecticidal components contained in the spray particles can adhere to the entire floor surface, and can exert an excellent control effect on creeping pests such as cockroaches and bed bugs. Moreover, by the injection volume of each injection of the quantitative injection valve within the above-mentioned range, and by injecting the aerosol stock solution from one to several times, the release amount of the insecticidal components can be appropriate, which can prevent cockroaches and bed bugs. Such as creeping pests, it exerts a practical and sufficient control effect.

In the aerosol for controlling pests of the present invention, it is preferable to set the specific gravity of the aerosol stock solution at 20°C as p, and when the ratio η ₃₀ /η _{10 is} set as q, (p)･(q) ² is 0.17～1.00.

According to the aerosol for pest control of this structure, by setting the specific gravity of the aerosol stock solution at 20°C as p, and setting the ratio η ₃₀ /η ₁₀ as q, set (p)･(q) ² above In the range, the spray particles formed by the spraying of the aerosol become more diffusible and settled. As a result, the insecticidal components contained in the spray particles can be uniformly attached to the entire floor surface. Based on this, if the parameter represented by (p)･(q) ² is used as an index to prepare an aerosol stock solution, it will be excellent for spaces and floors that can only be achieved with aerosols or full-volume jet aerosols so far. The aerosol for pest control with its pest control effect makes it possible to design aerosols as a quantitative spray type.

In the aerosol for controlling pests related to the present invention, preferably The aforementioned insecticidal ingredients contain Biofulin and/or Methelin.

According to the aerosol for controlling pests of the present composition, the insecticidal ingredient contains Biofluralin and/or Metternin, which can exert an excellent controlling effect against creeping pests such as cockroaches and bed bugs.

In the aerosol for controlling pests related to the present invention, preferably Take creeping pests as control targets.

According to the aerosol for pest control of the present structure, the spray particles formed by spraying have excellent diffusibility and sedimentation properties, so that the insecticidal components contained in the spray particles can adhere to the entire floor surface. Thereby, an excellent control effect can be exerted against creeping pests such as cockroaches and bed bugs that linger on the floor.

The characteristic structure of the method for controlling pests of the present invention to solve the above-mentioned problems is the use of an aerosol stock solution containing an insecticidal component and a solvent with ^{a vapor pressure of less than 1.5×10 -3 mmHg at 30°C, and a spray} A method for controlling insect pests by filling an aerosol container with a quantitative injection valve for controlling pests, and spraying them, characterized in that the specific gravity of the aerosol stock solution at 20°C is 0.82 to 1.25, and it is 10 ℃ viscosity [eta] of ₁₀ is 3.2 ~ 60.0mPa · s, the viscosity at 30 ℃ η ₃₀ and ₁₀ in a ratio of [eta] viscosity of 10 ℃ η ₃₀ / η ₁₀ from 0.40 to 0.92, each of the lines followed by quantitative injection valve injection capacity It is 0.1-3.0 mL, and sprays the aforementioned aerosol for pest control in the house toward the space.

The method of controlling a pest of the present configuration, by aerosol stock solution at 20 ℃ of gravity, a viscosity at 10 deg.] C to ₁₀ [eta], and the viscosity η _{30 30} ℃ and [eta] is the ratio η ₃₀ at ₁₀ deg.] C viscosity of 10 / η ₁₀ is the above-mentioned range. When the aerosol for controlling pests is sprayed in the room toward the space, the viscosity of the aerosol stock solution will not change rapidly due to the temperature change caused by the vaporization heat of the spray. Therefore, the spray particles settle quickly while properly spreading the spray particles. As a result, the insecticidal components contained in the spray particles can adhere to the entire floor surface, and can exert an excellent control effect against creeping pests such as cockroaches and bed bugs. In addition, the injection volume per shot of the quantitative injection valve is within the above range, and the aerosol stock solution is injected from one to several times, so that the release amount of the insecticidal component becomes appropriate, which can be used for cockroaches, bed bugs, etc. The creeping pests have a practical and sufficient control effect.

Hereinafter, the aerosol for controlling pests and the method for controlling pests of the present invention will be described. However, the present invention is not intended to be limited to the configuration described below.

[Aerosol for pest control] The aerosol for controlling pests of the present invention is a quantitative spray type aerosol used for controlling creeping pests through space treatment. The jet valve is composed of an aerosol container.

<Aerosol stock solution> In the aerosol for pest control of the present invention, the viscosity η _{10 of the} aerosol stock solution at 10°C is adjusted to 3.2-60.0mPa･s, preferably 4.0-20.0mPa･s, more preferably adjusted To 4.0～15.0mPa･s. And, in liquid aerosols viscosity η ₃₀ and 30 deg.] C to 10 deg.] C the viscosity ratio of η ₁₀ η ₃₀ / η ₁₀ is adjusted to 0.40 to 0.92, preferably adjusted to 0.60 to 0.90. If the viscosity η ₁₀ and the ratio η ₃₀ /η ₁₀ are in the above range, since the viscosity of the aerosol stock solution will not change rapidly due to temperature changes, a certain amount of the aerosol for pest control of the present invention is sprayed into the treatment space of the house. When the spray particles are properly diffused, they will settle quickly. As a result, the insecticidal components contained in the spray particles can adhere to the entire floor surface, and can exert an excellent control effect against creeping pests such as cockroaches and bed bugs. When the viscosity η _{10 is} out of the above range, after spraying, the temperature of the aerosol stock solution is lowered by the vaporization heat of the propellant, etc., and spray particles with sufficient diffusibility and settling properties cannot be formed. As a result, there are some problems. The adhesion amount of the insecticidal component on the floor surface becomes insufficient, or the adhesion state of the insecticidal component may vary greatly. In addition, when the ratio η ₃₀ /η _{10 is} less than 0.40, the spray particles may be insufficiently diffused. When the ratio η ₃₀ /η _{10 is} higher than 0.92, there is a risk of crawling insects such as cockroaches and bed bugs, and insufficient results are obtained. The effect of prevention and control. _{Furthermore, the viscosity η 30 of the} aerosol stock solution at 30° C. is preferably adjusted to 2.0-26.0 mPa·s, more preferably adjusted to 2.5-20.0 mPa·s, and still more preferably adjusted to 3.0-15.0 mPa·s. The viscosity η ₁₀ and η _{30 of the} aerosol stock solution can be measured with a viscometer. In this embodiment, the aerosol stock solution put in the beaker is placed in a constant temperature water tank (manufactured by IWAKI) and adjusted to 10°C or 30°C, using a B-type viscometer (manufactured by Tokyo Keiki Co., Ltd., Rotor Nо. 1), and measured at Viscosity at each temperature (measurement conditions: 60 rpm, 30 seconds).

In the aerosol for pest control of the present invention, the specific gravity of the aerosol stock solution at 20° C. is adjusted to 0.82 to 1.25, preferably to 0.83 to 1.20, and more preferably to 0.85 to 1.05. The specific gravity of the aerosol stock solution can be adjusted by changing the blending ratio of the insecticidal ingredient and the solvent, or by adding other ingredients. If the specific gravity of the aerosol stock solution at 20°C is in the range of 0.82 to 1.25, when a certain amount of the aerosol for controlling pests of the present invention is sprayed in the treatment space of the house, the insecticidal components will spread evenly and adhere to the entire floor surface. In the inner space, excellent control effects can be obtained for crawling pests such as cockroaches, bed bugs, or flying pests such as mosquitoes and flies, and particularly excellent control effects can be obtained for crawling pests such as cockroaches and bed bugs. However, in this specification, in addition to the repellent effect based on the knockdown effect or the lethal effect, the combined repellent effect is called the preventive effect. Even if the repelling effect is low, there is sufficient repellent effect, and there are many scenes where it can be prevented in practice. In addition, when the specific gravity of the aerosol stock solution at 20°C is in the above range, gaps or shadows are also performed during the process from the adherent particles to the sedimentation, and the pyrethrum-based compound is also sufficient when the insecticidal ingredient is used. Look forward to the flushing effect of cockroaches, etc. flying out of gaps or shadows. When the specific gravity of the aerosol stock solution at 20°C is less than 0.82, the adhesion amount of the spray particles to the floor surface may be insufficient. When the specific gravity of the aerosol stock solution exceeds 1.25 at 20°C, the adhesion state of the insecticidal components to the floor surface may become uneven.

However, in order to further enhance the pest control effect of the aerosol for pest control, the inventors found that when the specific gravity of the aerosol stock solution at 20°C is p and the ratio η ₃₀ /η ₁₀ is q, if Set (p)･(q) ² in an appropriate range. Although it is a quantitative spray type aerosol that does not require special preparation for space treatment, it can be compared with the conventional aerosol or full-volume spray type aerosol. It becomes possible to control the space and the entire floor surface as the target pest control. In the aerosol for controlling pests of the present invention, (p)･(q) ^{2 is} preferably adjusted to 0.17 to 1.00, more preferably adjusted to 0.17 to 0.69, still more preferably adjusted to 0.40 to 0.69, most preferably adjusted To 0.55 ~ 0.65. If (p)･(q) ² is in the range of 0.17 to 1.00, the spray particles formed by the aerosol spray will further improve the diffusibility and sedimentation. As a result, the insecticidal components contained in the spray particles will uniformly adhere to the floor The whole face. Therefore, the control effect on creeping pests can be further improved. In this way, the aerosol for controlling pests of the present invention uses ^{the parameter represented by (p)･(q) 2} as an index to prepare an aerosol stock solution. The so-called simple structure of a quantitative spray type aerosol can be adopted, and so far, For spaces and floors that can only be achieved with aerosols or full-volume jet aerosols, it can exert a very excellent pest control effect, which can be said to be a breakthrough product that has not been available so far.

(3) The adhesion rate and uniformity of the spread of insecticidal ingredients on the floor surface. A 20×20cm glass plate is installed at 6 to 8 points on the floor surface of ^{a room with a volume of 25m 3} (equivalent to a room with 6 tatami mats and an area of 10m ^{2 ).} . In Examples 1, 3 to 6, 8 to 11, 17 and 18, and Comparative Examples 1 to 3, in the center of the room (a height of 1.5m on the floor), the test aerosol was slightly inclined upwards per 0.4 mL side Change the direction and spray 4 shots on one side. In Examples 2, 13, and 16, toward the center of the room (a height of 1.5m on the floor), a spray of 1.0 mL of aerosol was sprayed slightly diagonally upwards. In Example 7, the test aerosol was sprayed with 6 guns per 0.2 mL in the center of the room (height of 1.5 m on the floor) while changing the direction slightly diagonally upward. In Examples 12 and 14, the test aerosol was sprayed with 4 guns per 1.0 mL in the center of the room (a height of 1.5 m on the floor) while changing the direction slightly upward. In Example 15, the test aerosol was sprayed with 6 guns per 0.4 mL in the center of the room (height of 1.5 m on the floor) while changing the direction slightly diagonally upward. After 1 hour from spraying, all the glass plates were taken out, and the attached insecticidal components were washed out with acetone and quantitatively analyzed by gas chromatography. Based on the obtained analytical values, the amount of insecticidal components deposited on the floor surface after 1 hour of spray treatment is calculated (by the total amount of insecticidal components attached to the glass plate × (the area of the room)/(glass plate) Calculate the ratio (floor adhesion rate) relative to the theoretical total spray amount of the insecticidal ingredient (see Table 1, which is equivalent to the amount of the insecticidal ingredient released multiplied by the volume).

The results are indicated by "A", "B", "C", and "D" in order from the ones with good uniformity of diffusion.

The test results are shown in Table 2.

As a result of the test, it was confirmed that the pest control aerosols of Examples 1 to 18 using the insecticidal ingredient at 30°C with a vapor pressure of less than 1.5×10 ^{-3 mmHg can be lethal to either cockroaches or bed bugs.} The rate has become a high lethal effect of 80% or more, and the KT ₅₀ value is lower than 8.3 points for German cockroaches, and a high knockdown effect of 18.0 points or less for wheeled cockroaches. Among them, it is confirmed that the vapor pressure at 30°C is 1.0×10 ^-4 mmHg or more and less than 1.5×10 ^-3 mmHg of pyrethrum-based insecticidal components in Examples 1-8, 11, 12, 14, The aerosols for pest control of 15, 17, and 18 have a _{high knockdown effect with a KT 50} value of 8.0 points or less for German cockroaches and 12.0 points or less for wheeled cockroaches. Especially in the use of the aerosols for pest control in Examples 1-7, 11, 12, 14, 15, 17 and 18 of Byfulin or Metherin, it is understood that it has both excellent lethal effects and excellent effects on cockroaches. The knock down effect. In addition, as a result of the test, it was confirmed that the aerosol for pest control of Examples 1-18 was sprayed for 1 hour, and not only did the insecticidal ingredients have a floor surface adhesion rate of more than 50%, but the insecticidal ingredients spread slightly evenly and adhere to the floor. The whole face. Embodiment Examples 1 to 18 of controlling pests with an aerosol, the aerosol since appropriate stock of [eta] at 20 ℃ gravity and viscosity at 30 deg.] C to ₃₀ [eta] is the ratio of viscosity at ₁₀ deg.] C to 10 η ₃₀ / η _10, so insecticidal The ingredients spread uniformly and adhere to the entire floor surface. As a result, it is considered that even at any position on the floor surface, the creeping pests and the insecticidal ingredients are in contact with efficiently.

In contrast, the aerosol for pest control of Comparative Example 1 has a _{small aerosol stock solution ratio η 30} /η ₁₀ , so the adhesion state of the insecticidal components to the floor surface becomes uneven, even for cockroaches and bed bugs. One kind is the one who cannot get the full lethal effect and knockdown effect. The aerosol for controlling pests of Comparative Example 2 has a _{large ratio of aerosol stock solution η 30} /η ₁₀ and a small specific gravity at 20°C. Therefore, the adhesion amount of the insecticidal components on the floor surface becomes insufficient, and it also affects the floor surface. The attachment state of the insecticidal ingredients becomes uneven, and even for any of cockroaches and bed bugs, the lethal effect and knockdown effect are significantly lower. In the aerosol for controlling pests in Comparative Example 3, it is considered that although the specific gravity and ratio η ₃₀ /η _{10 of the} aerosol stock solution at 20°C are appropriately adjusted, the vapor pressure of Empenthrin at 30°C due to the insecticidal ingredient is 1.5×10 ^-3 mmHg or more, the adhesion amount of the insecticidal ingredients to the floor surface becomes insufficient, and the adhesion state of the insecticidal ingredients to the floor surface becomes uneven, and sufficient lethal effects and knockdown effects cannot be obtained.
