Abstract
Description
本発明は、防除成分及び有機溶剤を含有するエアゾール原液、並びに噴射剤を、一回当たりの噴射容量が1.0~5.0mLである定量噴射バルブを備えたエアゾール容器に充填してなる害虫、ダニ防除用エアゾールを用いて噴射処理する害虫、ダニ防除方法、及び害虫、ダニ防除用エアゾールに関するものである。 The present invention is an insect pest that is filled with an aerosol stock solution containing a control component and an organic solvent, and an propellant in an aerosol container equipped with a fixed-quantity spray valve having a spray capacity of 1.0 to 5.0 mL per spray. , Pests to be sprayed using a mite control aerosol, a mite control method, and pests, a mite control aerosol.
床面や壁を徘徊するゴキブリ等の匍匐害虫や屋内塵性ダニ類を対象とし、匍匐害虫やダニ類が生息する場所や通り道に施用するタイプの殺虫剤としては、(1)燻煙剤、(2)全量噴射型エアゾール、(3)塗布型エアゾール、及び(4)ベイト剤が代表的で、それぞれ剤型上の特長を有している。 Targeting insecticides such as cockroaches that roam the floor and walls and indoor dust mites, the types of insecticides that are applied to places and passages where aerosol pests and mites inhabit are (1) smoke agents, Typical examples are (2) full-volume spray type aerosol, (3) coating type aerosol, and (4) bait agent, each of which has characteristics in terms of formulation.
(1)燻煙剤や(2)全量噴射型エアゾールは、薬剤を一気に室内の隅々まで放散し、所定時間室内を密閉して薬剤濃度を高め、その間、人が入室できないことから、医薬品の範疇に該当する。これらの製剤は、一度施用すれば2~4週間、匍匐害虫や屋内塵性ダニ類に対する駆除効果が持続する反面、使用前の手順に手間がかかること、薬剤の安全性に格別留意する必要があること等から、手軽に頻繁に採用される剤型とは言い難い。 (1) Smoke agent and (2) Full-injection aerosol dissipate the agent to every corner of the room at once, seal the room for a predetermined time to increase the concentration of the agent, and during that time, no one can enter the room. It falls under the category. Once applied, these formulations maintain their extermination effect against crawling pests and indoor dust mites for 2 to 4 weeks, but on the other hand, the procedure before use is time-consuming, and it is necessary to pay special attention to the safety of the drug. It is hard to say that it is an easy and frequently used dosage form.
一方、局所的に面処理する(3)塗布型エアゾールや、点処理の(4)ベイト剤は、人体に対する作用が緩和な医薬部外品に該当し、(1)燻煙剤や(2)全量噴射型エアゾールに較べると使い易いが、空間処理でないため薬剤と害虫やダニ類との接触効率が劣り、必ずしも効率的な駆除方法を提供できるものでもない。 On the other hand, (3) coating-type aerosols that are locally surface-treated and (4) bait agents that are point-treated correspond to quasi-drugs that have a mild effect on the human body, such as (1) smoke agents and (2). Although it is easier to use than a full-volume spray type aerosol, it is not spatially treated, so the contact efficiency between the drug and pests and mites is inferior, and it is not always possible to provide an efficient extermination method.
このように、従来、空間処理でありながら医薬部外品に該当する匍匐害虫や屋内塵性ダニ類用防除剤の開発は困難と考えられてきた。 As described above, it has been considered difficult to develop a control agent for crawling pests and indoor dust mites, which are quasi-drugs even though they are spatially treated.
ところで、特許文献1は、殺虫成分および溶剤を含む殺虫液を室内空間、収納空間等の空間内に蒸散させて匍匐害虫を駆除する方法であって、溶剤として特定の構造を有する化合物を用い、空間に粒子径の小さい殺虫液微粒子が浮遊し続けるべく、ピエゾ式噴霧器により殺虫液を少量ずつ時間をかけて蒸散させる匍匐害虫駆除方法を開示する。この特許文献1の方法は、液体電気蚊取りのように、微量の薬剤を継続して長時間にわたり空間に放散し、ゴキブリを駆除することを提案したものであるが、蚊に較べて数十倍薬剤に強いゴキブリを対象とする以上、強力な殺虫成分を使用せざるを得ず、人体に対する安全性の懸念が避けられない。 By the way, Patent Document 1 is a method of exterminating insect pests by evaporating an insecticidal liquid containing an insecticidal component and a solvent into a space such as an indoor space or a storage space, and uses a compound having a specific structure as a solvent. We will disclose a method for exterminating insect pests by evaporating the insecticide little by little with a piezo sprayer so that the insecticide fine particles with a small particle size continue to float in the space. The method of Patent Document 1 proposes to continuously dissipate a small amount of a drug into a space for a long period of time to exterminate cockroaches, such as liquid electric mosquito repellent, but it is several tens of times as much as that of mosquitoes. As long as we are targeting cockroaches that are resistant to drugs, we have no choice but to use powerful insecticidal ingredients, and there are unavoidable concerns about the safety of the human body.
本発明者らは、先に、空間処理剤であって、医薬部外品に該当する匍匐害虫や屋内塵性ダニ類用防除剤を開発するにあたり、(1)燻煙剤や(2)全量噴射型エアゾールのような2~4週間に一度の頻度で使用される製剤ではなく、1回定量噴霧処理すれば実用条件下で数日間防除効果が持続する、即ち基本的に1~2日に1回使用する製剤であって、人が居る状況下でも使用可能な安全性の高い製剤を目指して鋭意検討を行った。その結果、匍匐害虫や屋内塵性ダニ類のみならず、噴霧当日は飛翔害虫にも有効で、極めて有用な「害虫、ダニ防除方法」(特許文献2参照)を発明した。なお、この発明は、飛翔害虫に対する実用的な駆除効果をも実現するべく、エアゾールの噴射特性として、噴射後の噴霧粒子が、浮遊性粒子と、壁面等への付着並びに床面への沈降に関わる付着性粒子とに形成されるとともに、好ましくは、全体の噴霧粒子のうちの30~80%が噴射処理1時間後までに壁面等に付着するか、もしくは床面に沈降するように設計した。また、特許文献2の発明当時、定量噴射バルブの噴射容量としては0.2~0.4mLが一般的で、当該製剤は1回の処理において数プッシュ(噴射ボタンの押下)することが基本とされた。 In developing a space treatment agent for pests and indoor dust mites, which are quasi-drugs, the present inventors have previously developed (1) a smoke agent and (2) the total amount. It is not a formulation that is used once every 2 to 4 weeks like a jet-type aerosol, but a single fixed-quantity spray treatment lasts for several days under practical conditions, that is, basically for 1 to 2 days. We made a diligent study aiming at a highly safe formulation that can be used even in the presence of people, which is a single-use formulation. As a result, we invented an extremely useful "pest and mite control method" (see Patent Document 2), which is effective not only for crawling pests and indoor dust mites but also for flying pests on the day of spraying. In addition, in order to realize a practical extermination effect against flying pests, the present invention has the spraying characteristics of the aerosol that the sprayed particles adhere to the floating particles and the wall surface and settle on the floor surface. It is designed so that it is formed with the adherent particles involved, and preferably 30 to 80% of the total spray particles adhere to the wall surface or the like or settle on the floor surface within 1 hour after the injection treatment. .. Further, at the time of the invention of Patent Document 2, the injection capacity of the metering injection valve was generally 0.2 to 0.4 mL, and the pharmaceutical product was basically pushed several times (pressing the injection button) in one treatment. Was done.
一方、特許文献3には、定量噴射バルブを用いる匍匐害虫駆除用エアゾール製品及び匍匐害虫駆除方法が開示されている。このエアゾール製品は、エアゾール容器に収容される噴射剤の配合比率を高めるとともに、有効成分を溶解する溶剤の蒸気圧を低めにし、エアゾール容器から噴射された粒子を形成している溶剤の蒸発速度を遅くすることで、当該粒子が屋内の隙間の奥まで飛散するようにしたことを特徴とする。即ち、特許文献3の方法は、定量噴射処理であるとしても(3)塗布型エアゾールによる局所処理に該当し、空間処理に当たらない。従って、一部の隙間において局所的に高い駆除効果が得られたとしても、屋内全体にわたって匍匐害虫を効率的に駆除できるわけではない。 On the other hand, Patent Document 3 discloses an aerosol product for exterminating crawling pests using a fixed-quantity injection valve and a method for exterminating crawling pests. This aerosol product increases the mixing ratio of the propellant contained in the aerosol container, lowers the vapor pressure of the solvent that dissolves the active ingredient, and reduces the evaporation rate of the solvent that forms the particles ejected from the aerosol container. By slowing down, the particles are characterized in that they are scattered deep into the gaps in the room. That is, the method of Patent Document 3 corresponds to (3) local treatment with a coating type aerosol even if it is a quantitative injection treatment, and does not correspond to spatial treatment. Therefore, even if a high extermination effect is locally obtained in some gaps, it is not possible to efficiently exterminate crawling pests throughout the room.
かかる状況を鑑み、本発明者らは、特許文献2に基づく空間定量噴射処理が最も効率的な害虫、ダニ防除方法であるとの認識に則り、それの利便性を改善するとともに、特に匍匐害虫や屋内塵性ダニ類に対する更なる効能アップを目指して検討を行った。まず、近年開発されている噴射容量が1.0~5.0mLの定量噴射バルブを採用し、必要な有効成分量をワンプッシュで噴射可能とした。そのうえで、空間処理において、匍匐害虫のなかでも特にゴキブリ等に対する防除効果をアップさせるには、噴射後の噴霧粒子を、処理空間に浮遊する浮遊性粒子と、処理空間内の露出部に付着する付着性粒子として形成するだけでは足りず、付着性粒子を特許文献2の噴射特性と比較してより一層優占的となし、更に、付着性粒子のなかでも壁面等への付着よりも床面への沈降に関わる付着性粒子の比率を高めることが肝要との結論に達した。そして、本発明者らは、エアゾール原液の比重とエアゾールの噴射力が、沈降に関わる付着性粒子の挙動を決定する重要なファクターであることを知見し、試行錯誤を重ね試験を繰返し行った結果、前記エアゾール原液の比重とエアゾールの噴射力につき最適な範囲を特定することによって本発明を完成するに至ったのである。 In view of this situation, the present inventors have improved the convenience of the spatial quantitative injection treatment based on Patent Document 2 based on the recognition that it is the most efficient method for controlling pests and mites, and in particular, crawling pests. We conducted a study with the aim of further improving the efficacy against indoor dust mites. First, a fixed-quantity injection valve with an injection capacity of 1.0 to 5.0 mL, which has been developed in recent years, was adopted to enable one-push injection of the required amount of active ingredient. In addition, in the space treatment, in order to improve the control effect against cockroaches among the pests, the sprayed particles after spraying are attached to the floating particles floating in the treatment space and the exposed part in the treatment space. It is not enough to form as sex particles, and the adhesive particles are more dominant than the injection characteristics of Patent Document 2, and moreover, among the adhesive particles, they are more attached to the floor surface than to the wall surface or the like. It was concluded that it is essential to increase the proportion of adherent particles involved in sedimentation. Then, the present inventors have found that the specific gravity of the aerosol stock solution and the spraying force of the aerosol are important factors for determining the behavior of the adhesive particles involved in sedimentation, and as a result of repeated trials and errors. The present invention has been completed by specifying the optimum range for the specific gravity of the aerosol stock solution and the injection force of the aerosol.
本発明の目的は、容量が1.0~5.0mLの定量噴射バルブを備えた害虫、ダニ防除用エアゾールを屋内空間でワンプッシュするだけで匍匐害虫や屋内塵性ダニ類に対する防除効果を数日間持続させ得る害虫、ダニ防除方法、及び害虫、ダニ防除用エアゾールを提供することにある。 An object of the present invention is to obtain a number of pest control effects against pests and indoor dust mites by simply pushing an aerosol for controlling pests and mites equipped with a metered injection valve having a capacity of 1.0 to 5.0 mL in an indoor space. To provide pests, mite control methods, and pest and mite control aerosols that can be sustained for days.

本発明の害虫、ダニ防除方法、及び害虫、ダニ防除用エアゾールによれば、難揮散性化合物を含む特定の害虫、ダニ防除用エアゾールを屋内空間でワンプッシュして噴射処理するだけで、その処理区域において特に匍匐害虫や屋内塵性ダニ類に対する防除効果を数日間持続させることができる。利便的かつ効果的な害虫、ダニ防除方法、及び害虫、ダニ防除用エアゾールを提供するので、極めて実用的である。 According to the pest and mite control method of the present invention, and the pest and mite control aerosol, a specific pest and mite control aerosol containing a refractory volatile compound can be treated by simply injecting and spraying the pest and mite control aerosol in an indoor space. The control effect against pests and indoor dust mites can be sustained for several days, especially in the area. It is extremely practical because it provides a convenient and effective method for controlling pests and mites, and an aerosol for controlling pests and mites.
本発明では、防除成分として、30℃における蒸気圧が1×10-4mmHg未満である難揮散性化合物が使用される。かかる防除成分は、本発明の害虫、ダニ防除用エアゾールを屋内空間でワンプッシュする噴射処理後、主に付着性粒子として床面に沈降し、その屋内空間において特に匍匐害虫や屋内塵性ダニ類に対して優れた防除効果を示す。なお、本発明では、ノックダウン効果や致死効果に基づく駆除効果に加え、忌避効果を合わせて防除効果と呼ぶ。駆除効果が低くても十分な忌避効果があれば、実用上、防除が達せられる場面も多い。 In the present invention, a refractory compound having a vapor pressure of less than 1 × 10 -4 mmHg at 30 ° C. is used as a control component. After the injection treatment of one-pushing the pest and mite control aerosol of the present invention in the indoor space, the control component settles on the floor surface mainly as adhesive particles, and particularly in the indoor space, the pests and indoor dust mites. Shows excellent control effect against. In the present invention, in addition to the knockdown effect and the extermination effect based on the lethal effect, the repellent effect is collectively referred to as the control effect. Even if the extermination effect is low, if there is a sufficient repellent effect, there are many situations where control can be achieved in practice.
即ち、本発明は、特許文献2に基づく空間定量噴射処理が最も効率的な害虫、ダニ防除方法であるとの認識に則り、それの利便性を改善するとともに、特に匍匐害虫や屋内塵性ダニ類に対する更なる効能アップを目指したものである。まず、近年開発されている容量が1.0~5.0mLの定量噴射バルブを採用し、必要な有効成分量をワンプッシュで噴射可能とした。そのうえで、空間処理において、匍匐害虫のなかでも特にゴキブリ等に対する防除効果をアップさせるには、噴射後の噴霧粒子から形成される浮遊性粒子と付着性粒子のうち付着性粒子の優占度を高め、更に、付着性粒子のなかでも壁面等への付着よりも床面へ沈降する比率を高めることが肝要との方向性に基づき達成されたのである。なお、本発明の付着性粒子は、沈降に至る過程において隙間や物陰にも進入するため、防除成分としてピレスロイド系化合物を用いた場合には、ゴキブリ等が隙間や物陰から飛び出すフラッシング効果も十分期待し得るものである。 That is, the present invention is based on the recognition that the spatial quantitative injection treatment based on Patent Document 2 is the most efficient method for controlling pests and mites, and improves its convenience, and in particular, crawling pests and indoor dust mites. The aim is to further improve the efficacy of mites. First, a fixed-quantity injection valve with a capacity of 1.0 to 5.0 mL, which has been developed in recent years, was adopted to enable one-push injection of the required amount of active ingredient. In addition, in spatial treatment, in order to improve the control effect against cockroaches among the pests, the predominance of the floating particles and the adhesive particles formed from the spray particles after injection is increased. Furthermore, it was achieved based on the direction of the important point to increase the ratio of the adherent particles to settle on the floor surface rather than to adhere to the wall surface or the like. Since the adhesive particles of the present invention also enter gaps and shadows in the process leading to sedimentation, when a pyrethroid compound is used as a control component, a flushing effect in which cockroaches and the like pop out from gaps and shadows is sufficiently expected. It is possible.

The content of the control component in the aerosol stock solution is preferably about 1.0 to 70 w / v%. If the content of the control component in the aerosol stock solution is less than 1.0 w / v%, the desired control effect cannot be obtained, and if it exceeds 70 w / v%, it is difficult to stabilize the liquid of the aerosol stock solution.
本発明では、上記難揮散性の防除成分に加え、空間噴射処理後、噴霧粒子のある程度が気中に浮遊残存し、飛翔害虫に対しても防除効果を発揮し得るように、30℃における蒸気圧が2×10-4mmHg以上、1×10-2mmHg未満である常温揮散性の防除成分を加えてもよい。かかる常温揮散性防除成分としては、例えば、メトフルトリン、プロフルトリン、トランスフルトリン、エムペントリン、テラレスリン、及びフラメトリン等があげられる。常温揮散性防除成分は、難揮散性の防除成分と共に一部床面や壁面に付着すると、匍匐害虫及び/又は屋内塵性ダニ類に対する防除効果を相乗的に高め得ることが認められている。なお、常温揮散性防除成分には、蒸気圧や安定性、基礎殺虫効力等を考慮すると、メトフルトリン、プロフルトリン、及びトランスフルトリンが好ましく、これらの化合物の酸成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、それらの各々や任意の混合物も本発明に包含されることはもちろんである。 In the present invention, in addition to the above-mentioned refractory control component, after the space injection treatment, a certain amount of spray particles remain suspended in the air, and steam at 30 ° C. can exert a control effect against flying pests.

Examples of the room temperature volatilization control component include metoflutrin, profluthrin, transfluthrin, empentrin, terraresulin, and flamethrin. It has been recognized that the room temperature volatilization control component can synergistically enhance the control effect against crawling pests and / or indoor dust mites when partially adhered to the floor surface or wall surface together with the refractory volatilization control component. In consideration of vapor pressure, stability, basal insecticidal efficacy, etc., metoflutrin, profluthrin, and transfluthrin are preferable as the room temperature volatilization control component, and asymmetric carbon is used in the acid component and alcohol portion of these compounds. Of course, if there are optical isomers or geometric isomers based on them, each of them or any mixture thereof is also included in the present invention.
本発明では、上記難揮散性の防除成分を溶解するために有機溶剤を配合し、エアゾール原液を構成する。かかる有機溶剤としては、炭素数が2~3の低級アルコール、ノルマルパラフィンやイソパラフィンのような炭化水素系溶剤、ミリスチン酸イソプロピル(IPM)やラウリン酸ヘキシルのようなエステル系溶剤、炭素数3~10のグリコールエーテル系溶剤、ケトン系溶剤等があげられるが、エタノールやイソプロパノール(IPA)に代表される炭素数が2~3の低級アルコールが好ましい。 In the present invention, an organic solvent is blended in order to dissolve the above-mentioned refractory control component to form an aerosol stock solution. Examples of such organic solvents include lower alcohols having 2 to 3 carbon atoms, hydrocarbon solvents such as normal paraffin and isoparaffin, ester solvents such as isopropyl myristate (IPM) and hexyl laurate, and 3 to 10 carbon atoms. Examples thereof include a glycol ether solvent and a ketone solvent, but lower alcohols having 2 to 3 carbon atoms such as ethanol and isopropanol (IPA) are preferable.
本発明の害虫、ダニ防除方法は、難揮散性の防除成分を含む害虫、ダニ防除用エアゾールを用い、一回当たりの噴射容量を1.0~5.0mLとして屋内空間に噴射処理を行うことにより、その処理区域において匍匐害虫及び/又は屋内塵性ダニ類に対する防除効果を数日間持続させるものである。屋内空間のサイズは、4.5~8畳の部屋に相当する容積18.8~33.3m3(面積7.5~13.3m2、高さ2.2~3.0m)であることが好ましい。 In the method for controlling pests and mites of the present invention, an aerosol for controlling pests and mites containing a refractory control component is used, and the injection treatment is performed in an indoor space with a spray capacity of 1.0 to 5.0 mL each time. Therefore, the control effect against pests and / or indoor dust mites is maintained for several days in the treatment area. The size of the indoor space should be 18.8 to 33.3 m 3 (area 7.5 to 13.3 m 2 , height 2.2 to 3.0 m), which is equivalent to a room of 4.5 to 8 tatami mats. Is preferable.
噴射後の噴霧粒子は、処理空間に浮遊する浮遊性粒子、もしくは処理空間内の露出部に付着する付着性粒子として形成されるが、本発明者らは、付着性粒子を一層優占的となし、更に、付着性粒子のなかでも壁面等への付着よりも床面への沈降に関わる付着性粒子の比率を高めるための検討を行った。その結果、本発明者らは、エアゾール原液の比重とエアゾールの噴射力が、沈降に関わる付着性粒子の挙動を決定する重要なファクターであることを知見し、それらの最適な範囲を特定するに至った。即ち、エアゾール原液の比重が0.85~1.15、好ましくは0.89~1.10であり、噴射処理の噴射力が噴射距離5cmにおいて10~50gf、好ましくは15~35gfであれば、噴射から1時間後までに防除成分の60%以上が屋内空間の床面全体にわたり沈降・付着し、匍匐害虫、及びダニに対する優れた防除効果を奏し得ることを確認できたのである。なお、防除成分が「床面全体にわたり沈降・付着すること」について、防除成分が実際に床面全体にわたって沈降・付着しているかをその都度確認する必要はなく、エアゾールが処理空間内において本発明の趣旨に沿った態様で噴射されていれば、噴射された防除成分の床面に対する沈降・付着状態に多少の分布や偏りがあったとしても、防除成分が床面全体にわたり沈降・付着しているものと見做すことができ、このように見做しても実用上差支えはない。エアゾール原液の比重が0.85未満であると、噴霧粒子の床面への付着量が不足する傾向があり、エアゾール原液の比重が1.15を超えると、逆に噴霧粒子の沈降が速やか過ぎて床面全体への拡散性が不十分となる。また、噴射処理の噴射力が10gf未満であると、噴射力が不足して床面全体への拡散性が不十分となる傾向があり、噴射力が50gfを越えても良好な拡散性が得られない。なお、エアゾールの噴射力は、エアゾール原液の処方、エアゾールの内圧、噴口の形状等を変更することで、適宜調整することができる。 The spray particles after injection are formed as floating particles floating in the treatment space or adhesive particles adhering to the exposed portion in the treatment space, but the present inventors consider the adhesive particles to be more dominant. None, and further, we investigated to increase the ratio of adherent particles involved in sedimentation on the floor surface rather than adherence to the wall surface and the like. As a result, the present inventors have found that the specific gravity of the aerosol stock solution and the jetting force of the aerosol are important factors that determine the behavior of the adhesive particles involved in sedimentation, and identify their optimum range. I arrived. That is, if the specific gravity of the aerosol stock solution is 0.85 to 1.15, preferably 0.89 to 1.10, and the injection force of the injection process is 10 to 50 gf, preferably 15 to 35 gf at an injection distance of 5 cm. It was confirmed that 60% or more of the control components settled and adhered to the entire floor surface of the indoor space within 1 hour after the spraying, and that an excellent control effect against pests and mites could be achieved. Regarding "the control component settles and adheres over the entire floor surface", it is not necessary to confirm whether the control component actually settles and adheres over the entire floor surface each time, and the aerosol is used in the treatment space according to the present invention. If it is sprayed in a manner in line with the purpose of, even if there is some distribution or bias in the state of sedimentation / adhesion of the sprayed control component to the floor surface, the control component will settle / adhere to the entire floor surface. It can be regarded as something that exists, and there is no practical problem even if it is regarded in this way. If the specific gravity of the aerosol stock solution is less than 0.85, the amount of the spray particles adhered to the floor surface tends to be insufficient, and if the specific gravity of the aerosol stock solution exceeds 1.15, the spray particles settle too quickly. Therefore, the diffusivity to the entire floor surface becomes insufficient. Further, if the injection force of the injection process is less than 10 gf, the injection force tends to be insufficient and the diffusivity to the entire floor surface tends to be insufficient, and good diffusibility can be obtained even if the injection force exceeds 50 gf. I can't. The spraying force of the aerosol can be appropriately adjusted by changing the formulation of the aerosol stock solution, the internal pressure of the aerosol, the shape of the nozzle, and the like.
更に、害虫、ダニ防除用エアゾールは、エアゾール原液の充填量をa、噴射剤の充填量をb、エアゾール原液の比重をS、害虫、ダニ防除用エアゾールの噴射力をFとしたとき、以下の式(1):
δ = [a/(a+b)] × S2 × F ・・・ (1)
で定義するδが1.0~30の範囲にあることが好ましく、3.0~15の範囲にあることがより好ましい。
Further, for the pest and mite control aerosol, when the filling amount of the aerosol stock solution is a, the filling amount of the propellant is b, the specific gravity of the aerosol stock solution is S, and the spraying force of the pest and mite control aerosol is F, the following Equation (1):
δ = [a / (a + b)] × S 2 × F ・ ・ ・ (1)
It is preferable that δ defined in 1 is in the range of 1.0 to 30, and more preferably in the range of 3.0 to 15.
δが1.0~30の範囲にあれば、噴霧粒子が沈降したときに十分な量の防除成分が床面全体へ均一に拡散することで、好ましい防除効果が得られる。防除成分が床面全体へ均一に拡散するのは、害虫、ダニ防除用エアゾールから噴射される噴霧粒子の初速が適切なものとなり、噴射後、速やかに噴霧粒子が屋内空間の隅々まで行きわたるためと考えられる。δが1.0未満であると、防除成分の床面への付着量が不足する場合がある。一方、δが30を越えると、床面全体への拡散性が不十分となる場合がある。そのため、δが1.0~30の範囲を外れると満足のいく防除効果を奏し得ない虞がある。 When δ is in the range of 1.0 to 30, a sufficient amount of the control component is uniformly diffused over the entire floor surface when the spray particles settle, so that a preferable control effect can be obtained. The uniform diffusion of the control component over the entire floor surface is due to the appropriate initial velocity of the spray particles sprayed from the pest and tick control aerosol, and the spray particles quickly spread to every corner of the indoor space after spraying. It is thought that this is the reason. If δ is less than 1.0, the amount of the control component adhered to the floor surface may be insufficient. On the other hand, if δ exceeds 30, the diffusibility to the entire floor surface may be insufficient. Therefore, if δ is out of the range of 1.0 to 30, there is a possibility that a satisfactory control effect cannot be achieved.
害虫、ダニ防除用エアゾールは、害虫、ダニ防除用エアゾールの全容量(a+b)に対するエアゾール原液の充填量aの容量比率[a/(a+b)]が、以下の式(2):
0.1 ≦ [a/(a+b)] ≦ 0.5 ・・・ (2)
を満たすことが好ましい。容量比率が上記の範囲にあれば、十分な量の防除成分が床面全体へ均一に拡散する。容量比率が0.1より小さく噴射剤が多すぎると、防除成分の床面への付着量が不足する。一方、容量比率が0.5を超えると、噴霧粒子の沈降が速やか過ぎて床面全体への拡散性が不十分となる。
In the pest and mite control aerosol, the volume ratio [a / (a + b)] of the filling amount a of the aerosol stock solution to the total volume (a + b) of the pest and mite control aerosol is the following formula (2) :.
0.1 ≤ [a / (a + b)] ≤ 0.5 ... (2)
It is preferable to satisfy. When the volume ratio is within the above range, a sufficient amount of the control component is uniformly diffused over the entire floor surface. If the volume ratio is less than 0.1 and the amount of propellant is too large, the amount of the control component adhered to the floor surface is insufficient. On the other hand, when the volume ratio exceeds 0.5, the spray particles settle too quickly and the diffusivity to the entire floor surface becomes insufficient.
本発明で用いる害虫、ダニ防除用エアゾールは少量噴射であるため、敢えて火気に対する危険性に留意する必要はないが、できる限り火気に対する危険性を低減させる観点から水性化処方を採用することもできる。この場合、エアゾール原液に含まれる水の量は20~70v/v%程度が適当であり、噴霧粒子の噴射パターンに影響を与えない範囲で、可溶化助剤として若干量の非イオン系界面活性剤を添加してもよい。非イオン系界面活性剤としては、例えば、ポリオキシエチレンアルキルエーテル類、ポリオキシエチレンアルキルフェニルエーテル類、ポリオキシエチレンポリオキシプロピレンアルキルエーテル類、ポリオキシエチレンアルキルアミノエーテル類などのエーテル類、ポリエチレングリコール脂肪酸エステル類、ポリオキシエチレンソルビタン脂肪酸エステル類、ポリオキシエチレングリセリン脂肪酸エステル類などの脂肪酸エステル類、ポリオキシエチレンスチレン化フェノール、脂肪酸のポリアルカロールアミドなどがあげられ、なかでも、エーテル類が適している。 Since the pest and mite control aerosol used in the present invention is sprayed in a small amount, it is not necessary to pay attention to the danger to fire, but an aqueous formulation can be adopted from the viewpoint of reducing the danger to fire as much as possible. .. In this case, the amount of water contained in the aerosol stock solution is appropriately about 20 to 70 v / v%, and a small amount of nonionic surfactant is used as a solubilizing agent within a range that does not affect the injection pattern of the spray particles. Agents may be added. Examples of the nonionic surfactant include polyoxyethylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxyethylene polyoxypropylene alkyl ethers, ethers such as polyoxyethylene alkyl amino ethers, and polyethylene glycol.

上記害虫、ダニ防除用エアゾールは、一回当たりの噴射容量が1.0~5.0mLである定量噴射バルブを備え、屋内で一定量噴射処理に供される。従来、定量噴射バルブの噴射容量は0.2~0.4mLであったが、本発明で用いる定量噴射バルブにおいては容量の増量に伴い、必要な有効成分量がワンプッシュで噴射可能となった。その他、噴口、ノズル、容器等の形状については、その用途、使用目的等に応じて適宜選択することができる。例えば、上から押して噴射するボタンと斜め上方向きのノズルを備えた卓上タイプとしたり、小型容器の携帯用として設計することができる。 The pest and mite control aerosol is provided with a fixed-quantity injection valve having an injection capacity of 1.0 to 5.0 mL per injection, and is subjected to a constant amount injection treatment indoors. Conventionally, the injection capacity of the fixed-quantity injection valve was 0.2 to 0.4 mL, but in the fixed-quantity injection valve used in the present invention, the required amount of active ingredient can be injected with one push as the capacity is increased. .. In addition, the shapes of the nozzle, nozzle, container, etc. can be appropriately selected according to the intended use, purpose of use, and the like. For example, it can be a desktop type equipped with a button that is pushed from above to inject and a nozzle that faces diagonally upward, or it can be designed for carrying a small container.

By performing the injection treatment toward the air in the space, the amount of the control component released into the air is set to be 0.1 to 50 mg / m 3 , preferably 0.5 to 50 mg / m 3 . .. Injection processing is performed in an indoor space with a volume of 18.8 to 33.3 m 3 (area 7.5 to 13.3 m 2 , height 2.2 to 3.0 m) corresponding to a room of 4.5 to 8 tatami mats. In this case, the amount of the control component released into the air is usually 0.1 to 50 mg / m 3 by injecting the aerosol stock solution once, but in a larger indoor space, the volume of the indoor space is increased. By injecting the aerosol stock solution multiple times so that the amount of the control component released in the air is 0.1 to 50 mg / m 3 , the same control effect can be obtained regardless of the size of the indoor space. can. For example, when the injection process is performed in an indoor space having a volume of 37.6 to 66.6 m 3 (area 15 to 26.6 m 2 , height 2.2 to 3.0 m) corresponding to a room of 9 to 16 tatami mats. By spraying the undiluted aerosol solution twice, the amount of the control component released into the air becomes 0.1 to 50 mg / m 3 . The frequency of use of the pest and mite control aerosol is basically once every 1 to 2 days, if the amount of the control component released is within the above range, crawling pests and / or indoor dust mites. The control effect can be maintained for several days. It is also possible to impart a control effect against flying pests by using a room temperature volatilization control component in combination.

About 200 pre-determined test mites were placed in a petri dish with a high waist and tested. The test aerosol was sprayed in the center of the room slightly diagonally upward. After leaving it for 24 hours and exposing it to the drug, the mortality rate of the test mites was determined.
(3)屋内塵性ダニ類に対する忌避効果
上記「(2)屋内塵性ダニ類に対する駆除効果」試験において、供試ダニの替わりに直径約4cmの綿布を部屋の4隅に設置し、供試エアゾールをワンショット噴射した。噴射から24時間後にこの綿布を取り出して直径4cmのシャーレにはめ込み、シャーレの中央部に誘引用培地50mgを置いた。これとは別に、直径9cmのシャーレに供試コナヒョウヒダニ、又はケナガコナダニを培地とともに約10000匹放ち、この直径9cmのシャーレの中央部に、先に用意した直径4cmのシャーレを置いた。同様に、供試エアゾールによる処理を行わなかった綿布を用いて無処理区を用意した。24時間後に綿布上に侵入したダニ数を計数し、次式に従ってダニ忌避率を算出した。

(3) Repellent effect against indoor dust mites In the above "(2) Extermination effect against indoor dust mites" test, cotton cloth with a diameter of about 4 cm was installed at the four corners of the room instead of the test mites. One-shot spray of aerosol. Twenty-four hours after spraying, the cotton cloth was taken out and fitted into a petri dish having a diameter of 4 cm, and 50 mg of the citation medium was placed in the center of the petri dish. Separately, about 10,000 test Dermatophagoides farinae or Tyrophagoides farinae were released in a petri dish with a diameter of 9 cm together with the medium, and a petri dish with a diameter of 4 cm prepared earlier was placed in the center of the petri dish with a diameter of 9 cm. Similarly, an untreated plot was prepared using a cotton cloth that had not been treated with the test aerosol. After 24 hours, the number of mites that invaded the cotton cloth was counted, and the mites repellent rate was calculated according to the following formula.
Tick repellent rate (%) = [(Number of invading mites in untreated area-Number of invading mites in treated area) / Number of invading mites in untreated area] x 100
(4)防除成分の床面付着率
閉めきった容積25m3の部屋(面積10m2)の床面の6~8ヵ所に20×20cmのガラス板を部屋全体に均等に設置し、供試エアゾールを部屋の中央でやや斜め上方に向けてワンショット噴射した。噴射処理から1時間後に全てのガラス板を取り出し、付着した防除成分をアセトンで洗い出してガスクロマトグラフィーにより分析した。得られた分析値を基に、噴射処理から1時間後までに床面に沈降・付着した防除成分の、理論上の防除成分噴射全体量に対する比率(床面付着率)を求めた。また、ガラス板に付着した防除成分について、各ガラス板間のバラツキを解析し、噴霧粒子の拡散均一性を評価した。結果を、拡散均一性の良好なものから順に、A、B、C、Dの4段階で示した。
(4) Floor adhesion rate of control component 20 x 20 cm glass plates are evenly installed in 6 to 8 places on the floor of a closed room with a volume of 25 m 3 (area 10 m 2 ), and the test aerosol is used. Was sprayed slightly diagonally upward in the center of the room. One hour after the injection treatment, all the glass plates were taken out, and the adhered control components were washed out with acetone and analyzed by gas chromatography. Based on the obtained analytical values, the ratio (floor surface adhesion rate) of the control component that had settled and adhered to the floor surface within 1 hour after the injection treatment was determined with respect to the theoretical total amount of the control component injection. In addition, regarding the control component adhering to the glass plate, the variation between the glass plates was analyzed, and the diffusion uniformity of the spray particles was evaluated. The results are shown in four stages of A, B, C, and D in order from the one with the best diffusion uniformity.
試験の結果、実施例1~24の害虫、ダニ防除用エアゾールを用いた本発明の害虫、ダニ防除方法によれば、噴霧粒子が床面全体に略均一に拡散し、噴射から1時間後までに防除成分の60%以上が床面に沈降・付着することが確認された。また、難揮散性の防除成分として、匍匐害虫防除用化合物を配合した実施例1~16、20~24の害虫、ダニ防除用エアゾールを用いた場合には、匍匐害虫、及び屋内塵性ダニ類の何れに対しても、優れた防除効果を奏することが確認された。難揮散性の防除成分として、ダニ防除用化合物を配合した実施例17~19の害虫、ダニ防除用エアゾールを用いた場合には、屋内塵性ダニ類に対して優れた防除効果を奏することが確認された。 As a result of the test, according to the pests of Examples 1 to 24, the pests of the present invention using the mite control aerosol, and the mite control method, the spray particles diffused substantially uniformly over the entire floor surface until 1 hour after the injection. It was confirmed that more than 60% of the control components settled and adhered to the floor surface. In addition, pests of Examples 1 to 16 and 20 to 24 containing a compound for controlling pests as a resistant volatilization control component, and when an aerosol for controlling mites is used, pests and indoor dust mites. It was confirmed that an excellent control effect was exhibited for all of the above. When the pests of Examples 17 to 19 and the mite control aerosol containing the mite control compound are used as the refractory control component, an excellent control effect against indoor dust mites can be obtained. confirmed.
これに対し、比較例1~4では、匍匐害虫、屋内塵性ダニ類の何れに対しても十分な防除効果が得られなかった。比較例1では、防除成分として、エムペントリンのような常温揮散性ピレスロイド化合物のみを配合したエアゾールを用いたために、床面付着率が小さくなり、その結果、防除効果が低くなったと考えられる。比較例2では、噴射容量が0.4mLの定量噴射バルブを使用したために、ワンプッシュでは噴射される防除成分が必要量に達せず、その結果、防除効果が低くなったと考えられる。比較例3や比較例4のように、エアゾール原液の比重が本発明に規定する0.85~1.15の範囲から外れたものでは、噴霧粒子の拡散均一性が低かったことが、防除効果の低下の原因であると考えられる。 On the other hand, in Comparative Examples 1 to 4, sufficient control effect was not obtained for any of the crawling pests and indoor dust mites. In Comparative Example 1, since an aerosol containing only a room temperature volatilizing pyrethroid compound such as empentrin was used as the control component, it is considered that the floor adhesion rate was reduced, and as a result, the control effect was lowered. In Comparative Example 2, since the fixed-quantity injection valve having an injection capacity of 0.4 mL was used, it is considered that the control component to be sprayed did not reach the required amount by one push, and as a result, the control effect was lowered. When the specific gravity of the aerosol stock solution was out of the range of 0.85 to 1.15 specified in the present invention as in Comparative Example 3 and Comparative Example 4, the diffusion uniformity of the spray particles was low, which was the control effect. It is considered to be the cause of the decrease in.
本発明の害虫、ダニ防除方法、及び害虫、ダニ防除用エアゾールは、屋内だけでなく広範な害虫、ダニ防除を目的として利用することが可能である。 The pest and mite control method and the pest and mite control aerosol of the present invention can be used not only indoors but also for the purpose of controlling a wide range of pests and mites.
