Description
本発明は、多足類害虫防除用エアゾールに関するものである。 The present invention relates to an aerosol for controlling a pest of a multipod pest.
近年、都市郊外の農地や山林等の宅地化開発が進むなかで、ムカデ、ヤスデ等の多足類害虫が住宅地の近隣に出没することが多くなってきている。また、近年、ファミリーキャンプ等の郊外型レジャーが普及し、野外での活動が日常化したことで、ムカデ等と遭遇する機会が増えている。ムカデは落葉の下や朽木の中、石垣の隙間等に潜み、昆虫を常食としているが、夏場、山林に近い民家等では、ゴキブリなどを捕食するためにムカデがしばしば家屋内に侵入する。そして、靴の中や寝具に潜んでいたムカデによって咬害の被害が発生するので、非常に厄介な虫として認識されている。 In recent years, as housing land development such as farmland and forest in the suburbs of the city has progressed, it is becoming more common that polypod pests such as centipede and yaspde in the neighborhood of a residential area. Also, in recent years, suburban leisure activities such as family camps have become widespread, and outdoor activities have become routine, and opportunities to encounter centipede etc. are increasing. The centipede hides under the fallen leaves, in the mulberry trees, in the crevices of the stone wall, etc. and feeds on insects, but in summer and in private houses close to the forest, the centipede often invades the house to prey on cockroaches. And because the centipede caused by centipede lurking in shoes and bedding, it is recognized as a very troublesome insect.
従来より、ムカデ等の多足類害虫の駆除方法としては、例えばイソペンタンやノルマルペンタン等の害虫麻酔効果を利用して虫の動きを止めたうえで、殺虫成分がもたらす殺虫効果によって多足類害虫を駆除する方法が提案されている(特許文献１)。また、特許文献２では、カランー３，４−ジオールを保持させたシートを家屋等の侵入口に設置することで、ムカデ、ヤスデ等の多足類の家屋内への浸入を防除する多足類の防除用シートも提案されている。 Heretofore, as a method of controlling multipod pests such as centipede, for example, after stopping the movement of insects utilizing the pest anesthetic effect of isopentane, normal pentane and the like, polypod pest by the insecticidal effect brought about by the insecticidal component There has been proposed a method of exterminating (see Patent Document 1). Further, in Patent Document 2, a multipoda that controls entry into a house interior of a multipoda such as centipede and yasude by installing a sheet holding karan-3,4-diol at an entrance of a house etc. A sheet for controlling insects has also been proposed.
しかしながら、特許文献１は揮発性の高い溶剤の気化蒸気の麻酔効果を利用して動きを止めた後に、殺虫剤により致死させる方法であるが、これらの揮発性溶剤は可燃性であり、更に麻酔効果を発揮させるためには大量の溶剤を処理しなければならないことから、特に家屋内で処理する際は火気に対する危険性の問題が避けられなかった。また、特許文献２の防除用シートの場合、家屋内への侵入防止効果は期待できるが、見かけた害虫を駆除する効果は全く期待できない。 However, Patent Document 1 is a method of killing by an insecticide after stopping the movement by utilizing the anesthetic effect of the highly volatile solvent vapor, but these volatile solvents are flammable and are further anesthetized. Since a large amount of solvent has to be treated in order to be effective, the problem of danger to fire is inevitable, especially when treated in a house. Moreover, in the case of the sheet | seat for control of patent document 2, although the penetration prevention effect in a house can be anticipated, the effect which exterminates the pest which appeared is not expectable at all.
そこで、特許文献１の駆除方法の改良として、例えば、特許文献３のように、害虫行動阻害剤を噴射させるノズルを備えたエアゾールにおいて、ノズルの噴射剤流れ方向下流側の断面積を上流側に較べて大きく設定し、噴射した粒子径を大きくしながら害虫に多く付着させることができるようなエアゾールが開示されている。ここで、特許文献３で用いる害虫行動阻害剤は害虫に付着して気化熱によって害虫を冷却して行動を阻害するもので、あくまで直撃噴射のみを意図し、その噴霧パターンは従来のストレート型に較べると幾分狭く集中型となっている。しかしながら、動き回るゴキブリ等を主たる対象害虫としているため、ある程度の広い噴霧面積をカバーせざるを得ず、噴霧範囲の芯部(中心部)に速効的な効力を発揮させるに十分な薬剤量を必ずしも付着できるわけではなかった。一方、動きの鈍いムカデ等の多足類に対しては、集中的に薬剤付着量を高めるのが有効であり、特許文献３のエアゾールは多足類の防除目的に適合していないばかりか、用いる害虫行動防除剤の性状からみて多足類の害虫侵入に対する予防対策は何ら考慮されていない。 Therefore, as an improvement of the extermination method of Patent Document 1, for example, as in Patent Document 3, in the aerosol provided with a nozzle for jetting a pest activity inhibitor, the cross-sectional area of the nozzle downstream of the propellant flow direction There is disclosed an aerosol which can be set larger as compared with that and can be attached to a large number of pests while increasing the diameter of the sprayed particles. Here, the pest behavior inhibitor used in Patent Document 3 adheres to the pests and cools the pests by the heat of vaporization to inhibit the behavior, and only direct impact jet is intended, and the spray pattern is a conventional straight type. In comparison, it is rather narrow and concentrated. However, because the main target insect pest is moving cockroaches, etc., it is necessary to cover a wide spray area to a certain extent, and the amount of medicine sufficient for exerting a rapid effect on the core (central part) of the spray range is not necessarily required. It was not possible to adhere. On the other hand, for polypods such as centipede with slow movement, it is effective to increase the drug adhesion amount intensively, and not only the aerosol of Patent Document 3 is not suitable for the purpose of controlling polypods, From the nature of the pest control agent to be used, no preventive measures against the infestation of polypods are considered.
本発明は、噴霧範囲の芯部（中心部）の薬剤付着量を集中的に高める噴射システムを採用することによって、見かけた多足類害虫を直撃噴射で速効的に殺虫駆除できるとともに、多足類害虫の侵入路に残留噴霧処理することで、家屋内への害虫の侵入に対しても優れた侵入阻止効果を示す多足類害虫防除用エアゾールを提供しようとするものである。 According to the present invention, by adopting an injection system which intensively increases the amount of drug attached to the core (central part) of the spray range, it is possible to kill insects of found multipod pests by direct impact injection quickly and effectively. An object of the present invention is to provide a multipod pest control aerosol that exhibits an excellent entry preventing effect against the entry of pests into a house by applying a residual spray treatment to the entry path of the pest.

ここで、難揮散性とは、２５℃における蒸気圧が１×１０-5ｍｍＨｇ未満である化合物を言い、かかるピレスロイド系化合物としては、シフルトリン、フェノトリン、シフェノトリン、ペルメトリン、シペルメトリン、トラロメトリン、ビフェントリン、レスメトリン、フタルスリン、イミプロトリン、モンフルオロトリン及びエトフェンプロックス等を例示できるが、残留噴霧処理を施し、長期間にわたって害虫侵入防止効果をも発揮するためには、特にシフルトリン、ペルメトリン、エトフェンプロックスが好ましく、なかでもシフルトリンが特に好ましい。なお、直撃噴射の際により一層速効的な駆除効果が要求される場合には、難揮散性のピレスロイド系化合物のうちのフタルスリン、イミプロトリンやモンフルオロトリン等を併用するのが良い。
これら難揮散性ピレスロイド系化合物の配合量としては、例えば、エアゾール原液中に０．０１〜３．０ｗ／ｖ％、好ましくは０．０５〜１．５ｗ／ｖ％が適当である。配合量が０．０１ｗ／ｖ％未満では所望の防除効果が得られないし、一方、３．０ｗ／ｖ％を超えても格別のメリットは得られない。尚、ピレスロイド系化合物の酸部分やアルコール部分において、不斉炭素に基づく光学異性体や幾何異性体が存在する場合、これらの各々や任意の混合物も本発明に包合されることは勿論である。
The aerosol for controlling a multi-legged pest of the present invention contains one or more selected from non-volatile pyrethroid compounds as pest control components, and a saturated hydrocarbon solvent for dissolving and diluting it. It consists of an aerosol stock solution and liquefied gas as a propellant.
Here, the term “volatilization” refers to a compound having a vapor pressure of less than 1 × 10 −5 mmHg at 25 ° C. Examples of such pyrethroid compounds include cyfluthrin, phenothrin, cypenothrin, permethrin, cypermethrin, tralomethrin, bifenthrin , Resmethrin, phthalthrin, imiprothrin, montfluorothrin, etofenprox, etc., but in order to exert a residual spray treatment and also exert an insect-invasion preventing effect over a long period of time, especially sifluthrin, permethrin, etofenprox Among them, preferred is cyfluthrin. In the case where a more immediate effect of exterminating effect is required at the time of direct impact injection, it is preferable to use phthalthrin, imiprothrin, monfluorothrin, etc. among the non-volatile pyrethroid compounds.
As a compounding quantity of these non-volatile pyrethroid type compounds, 0.01-3.0 w / v% in an aerosol undiluted | stock solution, for example, 0.05-1.5 w / v% is suitable. If the blending amount is less than 0.01 w / v%, the desired control effect can not be obtained, while if it exceeds 3.0 w / v%, no particular advantage can be obtained. In the case where an optical isomer or a geometric isomer based on asymmetric carbon is present in the acid moiety or alcohol moiety of the pyrethroid compound, each of them or any mixture is of course included in the present invention. .
本発明においては、上記難揮散性ピレスロイド系化合物の溶解希釈溶剤として飽和炭化水素系溶剤を使用することに特徴を有する。飽和炭化水素系溶剤は、本発明の害虫防除成分である難揮散性ピレスロイド系殺虫剤の溶解性に優れるだけでなく、本発明における防除対象である多足類害虫に対する皮膚浸透性にも優れている。従って、上記難揮散性ピレスロイド系化合物を溶解したエアゾール原液が多足類害虫に付着した際に、飽和炭化水素系溶剤は殺虫成分の害虫体内浸透を促進し、殺虫効果を高めることも期待できるのである。 The present invention is characterized in that a saturated hydrocarbon solvent is used as a solvent for dissolving and diluting the non-volatile pyrethroid compound. The saturated hydrocarbon solvent is excellent not only in the solubility of the non-volatile pyrethroid insecticide which is the pest control component of the present invention but also in the skin permeability to the multipod pests to be controlled in the present invention. There is. Therefore, when the aerosol stock solution in which the above-mentioned nonvolatile pyrethroid compound is dissolved adheres to a multipodal pest, the saturated hydrocarbon solvent can be expected to promote the penetration of the pesticidal component into the pest and enhance the insecticidal effect. is there.
噴射剤としては、液化ガス、例えば、液化石油ガス（ＬＰＧ）、ジメチルエーテル（ＤＭＥ）等が用いられる。そのうちの一種であっても混合ガスであってもよいが、通常ＬＰＧを主体としたものが使いやすい。なお、フルオロカーボンガスや、噴射圧の調整のために、窒素ガス、炭酸ガス、亜酸化窒素、圧縮空気等の圧縮ガスを適宜添加しても構わない。
上記エアゾール原液と噴射剤との配合比率については特に規定はないが、害虫の侵入防止を目的した残留噴霧処理用途に使用する場合の塗布効率を考慮すると、エアゾール原液／噴射剤比率は容量比として７５／２５〜２５／７５％が、好ましくは７０／３０〜３０／７０％に設定するのが適当である。
As the propellant, a liquefied gas, for example, liquefied petroleum gas (LPG), dimethyl ether (DME) or the like is used. It may be a kind of gas or a mixed gas, but it is usually easy to use one mainly composed of LPG. A fluorocarbon gas or a compressed gas such as nitrogen gas, carbon dioxide gas, nitrous oxide, or compressed air may be added as appropriate to adjust the injection pressure.
The blending ratio of the aerosol undiluted solution to the propellant is not particularly specified, but considering the coating efficiency in the case of use for residual spray treatment intended to prevent the infestation of pests, the aerosol undiluted solution / propellant ratio is a volume ratio It is appropriate to set 75/25 to 25/75%, preferably 70/30 to 30/70%.

かかる三段階構成の噴射用ボタンを採用することによって、エアゾール容器から流出した害虫防除剤は、ボタンの連通路の内径（Ａ３）が噴射用ノズルの入口側の内径（Ａ１）より小さいために勢いよく噴出するとともに、ノズルの出口側の内径（Ａ２）がＡ１に較べて大きく設計されていることに起因して、噴霧処理範囲に薬剤付着量が集中的に高められた芯部を形成する噴霧パターンを実現したのである。
ここで、噴霧パターンの指標として、１５ｃｍ離れた垂直板面に向けてエアゾールを噴射後、その板面の濡れた部分の最大直径（ＳＰ）で表すとき、上記噴霧処理範囲のＳＰは６〜１３ｃｍ程度、芯部のＳＰは２〜５ｃｍ程度が目安となる。
By adopting such a three-step injection button, the pest control agent that has flowed out of the aerosol container is more effective because the inner diameter (A3) of the communication passage of the button is smaller than the inner diameter (A1) on the inlet side of the injection nozzle. Spray that forms a core part where the drug adhesion amount is intensively increased in the spray processing range due to the fact that the inner diameter (A2) on the outlet side of the nozzle is designed to be large compared to A1 while spraying well I realized the pattern.
Here, after spraying the aerosol toward the vertical plate surface separated by 15 cm as an index of the spray pattern, when represented by the maximum diameter (SP) of the wet portion of the plate surface, the SP in the spray processing range is 6 to 13 cm. The degree and SP of the core part will be about 2 to 5 cm as a guide.
これに対し、特許文献３のエアゾールで用いる噴射ノズルには、本発明の噴射用ノズルの入口側の内径（Ａ１）及び出口側の内径（Ａ２）に相当する構成が開示されているが、この二段階構成では従来のストレート型に較べて幾分狭い噴霧パターン（ＳＰ：７ｃｍ程度）が得られるだけで、噴霧処理範囲に上述のような芯部が必ずしも形成されるわけではない。 On the other hand, in the injection nozzle used in the aerosol of Patent Document 3, a configuration corresponding to the inner diameter (A1) on the inlet side and the inner diameter (A2) on the outlet side of the injection nozzle of the present invention is disclosed. In the two-stage configuration, only a somewhat narrower spray pattern (SP: about 7 cm) can be obtained as compared with the conventional straight type, and the core portion as described above is not necessarily formed in the spray processing area.
本発明の多足類害虫防除用エアゾールで用いる噴射用ボタンの具体的な構成としては、噴射用ノズルの入口側の内径（Ａ１）が０．５〜１．０ｍｍ、出口側の内径（Ａ２）が０．８〜２．０ｍｍ、及び連通路の内径（Ａ３）が０．４〜０．８ｍｍであることが好ましく、更に、Ａ３：Ａ１の孔径比が１：１．２〜１：２．５である噴射用ボタンが性能上極めて効果的であることが認められた。
なお、噴射用ノズルが別体にて噴射用ボタンに接続される場合において、噴射用ノズルの入口側端部と連通路の間に密閉された小空間を設け、害虫防除剤を連通路（内径：Ａ３）から一旦拡散させた後入口側端部（内径：Ａ１）で再度絞り込むことによって、噴霧処理範囲に上述のような芯部を有した状態で噴霧処理範囲を拡大させることも可能である。
As a specific configuration of the button for injection used in the multi-legged insect pest control aerosol of the present invention, the inner diameter (A1) on the inlet side of the injection nozzle is 0.5 to 1.0 mm, the inner diameter on the outlet side (A2) Is preferably 0.8 to 2.0 mm, and the inner diameter (A3) of the communication passage is preferably 0.4 to 0.8 mm, and further, the pore diameter ratio of A3: A1 is 1: 1.2 to 1: 2. It was found that the injection button, which is 5, was extremely effective in performance.
In the case where the injection nozzle is separately connected to the injection button, a small space sealed between the inlet end of the injection nozzle and the communication passage is provided, and the pest control agent is After spreading from A3), it is possible to expand the spray processing range with the core as described above by narrowing again at the inlet side end (inner diameter: A1). .

As a result of the test, an aerosol container containing a pest control agent comprising the aerosol stock solution of the present invention, that is, an aerosol stock solution containing a pyrethroid compound of a nonvolatile nature and a saturated hydrocarbon solvent, and a propellant is provided. An aerosol for pest control provided with a spray button having a specific configuration can be applied to a polypod pest by adopting a spray system that intensively increases the amount of drug attached to the core (central portion) of the spray range. It has become clear that it is possible to prevent the infestation of pests for a long period of time by the residual spray treatment, as well as being excellent in the quick-acting control effect by the direct impact injection.
In addition, the nozzle for injection is integrally or separately connected to the button for injection of the aerosol for pest control of multipod pests of the present invention through the communication passage, and the injection flow path in the nozzle for injection is The inner diameter (A1) on the inlet side is set smaller than the inner diameter (A2) on the outlet side, and the inner diameter (A3) of the communication passage is set smaller than the inner diameter (A1) on the inlet side of the injection nozzle.
Here, as shown in Inventions 3 and 4, A1 is 0.5 to 1.0 mm, A2 is 0.8 to 2.0 mm, and A3 is 0.4 to 0.8 mm, and A3: It was preferred that the pore size ratio of A1 be 1: 1.2 to 1: 2.5.
これに対し、噴射用ボタン乃至噴射用ノズルの内径の構成が本発明の範囲から外れる比較例１（従来のストレート構造）、比較例２（噴射用ノズルが２段階構造のみ）、及び比較例３（Ａ１とＡ３が同等）では、平均回収率が劣るうえ中心部の付着量が十分と言えず、直撃噴射によるムカデに対するノックダウン効果はそれ程改良されなかった。更に、比較例４のように、エアゾール原液の溶剤としてエタノールを使用した防除用エアゾールは速効性が劣り、また、害虫防除成分として常温揮散性ピレスロイド系化合物のみを配合した比較例５は、害虫の侵入防止効果が持続せず本発明の目的に合致しなかった。 On the other hand, Comparative Example 1 (conventional straight structure), Comparative Example 2 (only the jet nozzle has a two-stage structure), and Comparative Example 3 in which the configuration of the inner diameter of the injection button or the injection nozzle deviates from the scope of the present invention. In (A1 and A3 are equal), the average recovery rate is poor and the adhesion amount in the central portion is not sufficient, and the knockdown effect on the centipede by direct impact injection is not so improved. Furthermore, as in Comparative Example 4, the control aerosol using ethanol as the solvent of the aerosol stock solution is inferior in immediate effect, and Comparative Example 5 in which only the normal temperature volatile pyrethroid compound is blended as a pest control component is a pest The intrusion prevention effect did not last and did not meet the object of the present invention.
本発明の多足類害虫防除用エアゾールは、家屋内、屋外を問わず広範な害虫防除を目的として利用することが可能である。
