Japanese Patent Laid-Open No. 2001-200299 JP 2001-279033 A JP 2008-194034 A

The present invention is a chemical volatilization body used by storing a carrier containing a room temperature volatile chemical in a flat drug container and fixing it to a screen door. In addition, a chemical volatilization agent that can be efficiently volatilized and spreads throughout the screen door, and can eliminate or repel flying insect pests such as mosquitoes and flyfish, and a method for controlling flying insects using the same. It is a thing.

The present invention has been found that the following constitution has an excellent effect for achieving the above-mentioned object. That is,
(1) A drug volatilization body in which a carrier containing a room temperature volatile drug is housed in a flat drug container, wherein the drug container has a thickness of 3 mm to 10 mm, and the carrier, the drug container inner surface, A chemical volatilizer used by being fixed to a screen door, and a method for controlling flying insects using the same, characterized in that a gap of 1 mm or more is provided between them.
(2) The ratio (A) / (B) of the opening area (A) on the outdoor side of the medicine container and the opening area (B) on the indoor side is 2/1 to 1/2 (1) The chemical volatilization body used by being fixed to the screen door described in the above) and a flying insect control method using the same.
(3) The carrier containing the room temperature volatile drug is a network structure composed of a polyolefin resin, and the wire diameter thereof is 0.1 to 2 mm. (1) or (2) A chemical volatilizer fixed to a screen door and a flying insect control method using the same.
(4) A plurality of reticulated carriers containing the room temperature volatile drug are housed in the drug container, and are used by being fixed to the screen door according to any one of (1) to (3) Chemical volatilization body and flying pest control method using the same.
(5) The volatile drug according to any one of (1) to (4), wherein the room temperature volatile drug is one or more of metofluthrin, profluthrin, empentrin, and transfluthrin. .
(6) The method for controlling flying insects according to any one of (1) to (5), wherein the chemical volatilization body is fixed to a screen door using a hook-and-loop fastener.

By the chemical volatilization body of the present invention and the pest control method using the chemical volatilization body, the flying pests such as mosquitoes and flyfish can be controlled or avoided efficiently without interfering with windows and shutters, and its practicality is extremely high.

The chemical volatilization body of the present invention is fixed to a screen door to eliminate or repel flying insects such as mosquitoes and flyfish. When fixing a chemical volatilization body to a screen door, it is necessary to make a chemical | medical agent container into a flat shape so that it may not become obstructive when opening and closing a window and a shutter. In the drug volatilization body of the present invention, when the air flows on the surface of the carrier housed in the container, the drug contained in the carrier is gradually volatilized and exhibits the effect. In the case of a flat shape as described above, by providing a certain gap between the carrier and the inner surface of the container, air passes through the gap and the drug is efficiently vaporized from the entire carrier.

In the present invention, the thickness of the drug container is 3 mm to 10 mm, and the gap between the carrier and the container inner surface is 1 mm or more. It was found that it spreads efficiently over the entire mesh and exerts its effect. When the thickness of the container is less than 3 mm, the gap between the carrier and the inner surface of the container is not maintained, and there is less air flowing on the surface of the carrier, resulting in poor volatilization efficiency. Conversely, if it exceeds 10 mm, not only is it not very advantageous for volatilization efficiency, but there is a possibility that the container will get caught when opening and closing windows and shutters. In addition, when the gap between the carrier and the inner surface of the container is less than 1 mm, air does not enter the entire container, and only the air passes through the opening portion of the container. The volatilization amount is reduced and a stable effect cannot be achieved for a certain period. Therefore, in the case of a compact container shape, it is an essential requirement to ensure a gap of 1 mm or more between the carrier and the container.

In the present invention, the ratio (A) / (B) of the opening area (A) on the outdoor side of the medicine container and the opening area (B) on the indoor side is preferably 2/1 to 1/2.
Normally, the flow of air is generally considered to flow through the inside of the container after flowing from the opening on the outdoor side of the container, or out of the container from the opening on the indoor side. It is important in controlling the volatilization amount of sex medicine. When the container thickness is small, the amount of air is small, and if there is an extreme difference in the opening area between the outdoor side and the indoor side, the volatilization amount of the drug is remarkably reduced.
Furthermore, the ratio (A) / (B) of the opening area (A) on the outdoor side of the medicine container and the opening area (B) on the indoor side is more preferably 1/1 to 1/2.

Since the shape of the medicine container used in the present invention is a usage method for attaching to a screen door, it is desirable that the shape is a flat shape. In addition, examples of the shape include a substantially rectangular parallelepiped, a substantially cylindrical shape, and a substantially elliptical shape. However, the shape is not limited to these, and the shape can be adapted to the preference.
As a structure of a container, what bent the planar sheet-like resin member is mentioned, for example. In this case, the container is assembled using two of the folded members as a set, and the folded surfaces of the members are overlapped. Also, an integrally molded product of resin can be used. The resin integrally molded product here may be any molding method as long as it is molded by normal injection molding or vacuum molding, etc., but the outdoor side and the indoor side are integrated using a hinge or fitted. If integrated, the manufacturing process can be further simplified.

As resin materials used in these containers, various resin materials such as polyethylene terephthalate (PET), polyethylene, polypropylene, polybutylene terephthalate (PBT), nylon, and polyamide can be used. Polyethylene terephthalate (PET) or polybutylene terephthalate (PBT) is preferably used.

Various thicknesses of these resins can be used, but it is preferable to use those having a thickness of 0.05 mm to 2 mm from the viewpoint of the shape of the resin carrier, its volatilization performance, economy, and the like.

As the carrier used in the present invention, a carrier in which a volatile chemical is held by impregnation or kneading is used. Paper, fiber, resin, etc. can be used as the material, but if a resin-made material with an active ingredient is used, the sustained release of the drug during the period of use can be controlled and the amount of drug volatilized is stable. It is preferable from the viewpoint that it is possible to realize the above and that there is no worry of the drug flowing down due to moisture such as rain. As the resin material, polyolefin resins such as polyethylene, polypropylene, polyvinyl alcohol, polyvinyl acetate, polybutadiene, polyisoprene, ethylene-methyl methacrylate copolymer, styrene-butadiene copolymer are preferable.

The shape of the resin carrier used in the present invention is preferably a net shape considering the volatilization efficiency of the drug. The wire diameter of the net is also preferably in the range of 0.1 to 2 mm from the viewpoint of volatilization efficiency, but may be appropriately set from the above range depending on the type of drug and the period of use. In other words, in the case of a drug with a high vapor pressure, adjustment is made to suppress volatilization by increasing the wire diameter, and in the case of a drug with a low vapor pressure, adjustment is made to promote volatilization by reducing the wire diameter. To do.

The drug used in the present invention is not particularly limited as long as it has a property of volatilizing at room temperature and volatilizes in the air. It is preferable to use a pyrethroid based on the point that a more powerful effect can be exerted. Among them, one or more of metfurthrin, profluthrin, enpentrin, and transfluthrin, which have high volatility and high basic activity against flying insects, are preferable.

In the present invention, a plurality of carriers containing a drug can be stacked and stored in a drug container. By using a plurality of carriers, the chemical volatilization area increases, and the amount of chemical volatilization per unit time can be increased accordingly. In addition, by changing the type and concentration of the drug and the wire diameter of the net for each of a plurality of carriers, it is possible to obtain a preparation that takes advantage of the characteristics of each drug.

The blending amount of the room temperature volatile drug held on the carrier varies depending on the type of drug used, but the amount of active ingredient that exhibits the effect is ensured, the moldability after kneading the drug into the resin, and the carrier surface From the viewpoint of preventing the drug from bleeding and causing stickiness, the content is preferably in the range of 2 to 12% by weight. That is, when the compounding amount of the drug is less than 2% by weight, it is difficult to ensure an effective ingredient amount that exhibits the effect. On the other hand, when the content exceeds 12% by weight, it is difficult to form a mesh, and the drug tends to bleed on the surface of the mesh and cause stickiness.

In addition, synergists, repellents, antibacterial agents, antifungal agents, fragrances and the like can be used at the same time for the drugs used in the present invention. For example, as synergists, octachlorodipropyl ether (trade name) S-421), isobornyl thiocyanoacetate (trade name IBTA), N-octylbicycloheptenecarboximide (trade name Sinepilin 222), N- (2-ethylhexyl) -1-isopropyl-4-methylbicyclo [2 , 2, 2] octo-5-ene-2,3-dicarboximide (trade name Sinepirine 500). As repellents, N, N-diethyl-m-toluamide (trade name Diet), dimethyl phthalate, dibutyl phthalate, 2-ethyl-1,3-hexanediol, 1,4,4a, 5a, 6,9,9a , 9b-octahydrodibenzofuran-4a-carbide, p-menthane-3,8-diol, and the like.

Examples of the antifungal agent include isopropylmethylphenol and orthophenylphenol.
Air fresheners include citronella oil, orange oil, lemon oil, lime oil, yuzu oil, lavender oil, peppermint oil, eucalyptus oil, jasmine oil, hinoki oil, green tea essential oil, limonene, α-pinene, linalool, geraniol, phenylethyl Examples include alcohol, amylcinnamic aldehyde, cuminaldehyde, and benzyl acetate.
Furthermore, you may mix | blend a fragrance | flavor, a coloring agent, an antistatic agent, etc. suitably.
Moreover, although all the chemical | medical agents used by this invention have sufficient stability, in order to raise stability further, it is also possible to add stabilizers, such as antioxidant, for example, 2,2'-. Methylene bis (4-ethyl-6-tert-butylphenol), 4,4′-methylene bis (2-methyl-6-tert-butylphenol), BHT, BHA, mercaptobenzimidazole and the like can be used.
Furthermore, by using ultraviolet absorbers such as paraaminobenzoic acids, cinnamic acids, salicylic acids, benzophenones and benzotriazoles as ultraviolet absorption inhibitors, the light resistance during storage and use can be further improved.

In the present invention, as a method for fixing the drug container to the screen door, a hook-and-loop fastener, a hook, an adhesive tape, an adhesive gel, and the like can be used, but fixing to the fine screen of the screen door and excellent rain resistance and light resistance are also possible. In consideration of what is required, it is preferable to securely fix the surface fastener using a hook-and-loop fastener. About the installation position to the container of a fixing tool, although installation to multiple places is preferable, what is necessary is just to enlarge as much as possible in the range which does not impair the external appearance of a formulation even in the case of 1 place fixation. And after attaching the chemical | medical agent container of this invention to the outdoor side of a screen door, it is convenient to fix using the hook-and-loop fastener from the indoor side of a screen door.

Next, although the test example of this invention is demonstrated, this invention is not limited only to these test examples.

A resin net carrier (length: 110 mm, width: 60 mm) containing 100 mg of metfurthrin was accommodated in a substantially rectangular parallelepiped drug container (length: 115 mm, width: 65 mm, thickness: 5 mm) made of transparent polyethylene terephthalate (PET). The gap between the carrier and the inner surface of the drug container was 2 mm, and the opening ratio between the outdoor side and the indoor side of the drug container was 1/1.

(Efficacy test)
A small room was created with an 18-mesh screen (length 190 cm, width 90 cm) in one corner of a 100 m ³ room (room temperature 25 ° C.). One volunteer entered this small room, 50 squid were released from a position 5 m away from the screen, the number of squid was stopped on the screen, and the adhesion prevention rate was calculated by the following formula.
Adhesion prevention rate (%)
= (Number of deposits in untreated section-Number of deposits in treated section) / Number of deposits in untreated section × 100
<Evaluation>
◎: Adhesion prevention rate is 80% or more ○: Adhesion prevention rate is 60% or more to less than 80% △: Adhesion prevention rate is 40% or more to less than 60% ×: Adhesion prevention rate is less than 40%

According to Example 1, the evaluation was performed using the drug carrier and drug container shown in Table 1.

As a result of the test, when the carrier containing the room temperature volatile drug is stored in a flat drug container having a thickness of 3 mm to 10 mm and the gap between the carrier and the container inner surface is 1 mm or more, the flying insects for a certain period of time. An excellent effect was observed that was not able to keep up.
On the other hand, when the thickness of the drug container was less than 3 mm and the gap between the carrier and the container was less than 1 mm as in Comparative Example 1, it was difficult for air to enter the container and the repelling effect was reduced. In Comparative Example 2, when the thickness of the drug container is 12 mm and the opening ratio between the outdoor side and the indoor side of the container is 1/3, it becomes an obstacle when opening and closing the window, and the air flow in the container However, it became inefficient and the repellent effect did not last. Further, in Comparative Examples 3 and 4, the thicknesses of the containers were 8 mm and 5 mm, respectively, and it was easy for air to enter. However, since the thickness of the carriers was increased, the gap between the carrier and the inner surface of the container was less than 1 mm. For this reason, the flow of air did not occur in the container, and although the effect was recognized in the initial stage, the efficacy was reduced thereafter.

INDUSTRIAL APPLICABILITY The present invention provides a chemical volatilizer for fixing or repelling flying insect pests such as mosquitoes and flyfish by fixing to a screen door, and an insect repellent method using the same, and is suitable for the field of controlling or repelling insect pests.
