Description
本発明は、害虫を駆除する方法に関する。 The present invention relates to a method for controlling pests.
ヒトの生活環境において、比較的閉鎖された場所（閉鎖空間）が多数存在する。閉鎖空間は、温度、湿度等の環境が安定しているために、有害生物が繁殖しやすく、特に近年では寝室のベッド、床に敷かれたカーペット等の人に目に触れにくい隙間に棲息するトコジラミの繁殖が大きな問題となっている。このトコジラミによる吸血により、ヒトは血液を失うだけでなく、耐えがたい痒みを感じ、この痒みにより睡眠が妨げられて日常生活に支障をきたしたり、発疹、皮膚炎等が生じたりすることも多い。 In the human living environment, there are many relatively closed places (closed spaces). Closed spaces have a stable environment such as temperature, humidity, etc., so that pests are easy to breed, and in recent years, inhabited in gaps that are difficult to see, such as bedroom beds and carpets on the floor. The breeding of bed bugs is a big problem. By this blood sucking by bed bugs, humans not only lose blood but also feel unbearable itching, and this itching often disturbs sleep and disturbs daily life, and rashes, dermatitis, etc. often occur.
一般に、有害生物を駆除するために殺虫剤等を散布することが通常行われるが、トコジラミは非常に小さいばかりか、寝具や衣類の縫い目、カーペットなどの人の目に触れにくい場所で棲息、繁殖するなど、蚊やゴキブリなどの他の衛生害虫とは非常に異なった環境で棲息しているため、一般的な殺虫剤の散布による駆除は極めて難しい。また、閉鎖空間であっても、通常の燻煙剤やエアゾール剤による空間噴霧等によってはトコジラミの棲息域まで殺虫剤が十分に行き渡らず、トコジラミに対する有効な駆除方法として十分とは言えなかった。 In general, spraying insecticides to control pests is usually used, but bed bugs are not only small, but they are also inhabited and propagated in places that are difficult to touch the eyes such as bedding, clothing seams, and carpets. Because it lives in a very different environment from other sanitary pests such as mosquitoes and cockroaches, it is extremely difficult to disinfect by spraying general insecticides. In addition, even in a closed space, pesticides did not spread sufficiently to the resident area of bed bugs due to space spraying with ordinary smoke or aerosol agents, and it was not sufficient as an effective extermination method for bed bugs.
エアゾール剤の噴霧以外による害虫駆除の方法としては、液化炭酸ガスに溶解させた薬剤を噴霧する器具および装置が知られている。特許文献１には、液化炭酸ガスに殺虫成分を溶解した防虫器具が記載されており、ゴキブリに対する殺虫効果が示されている。特許文献２には、有効成分が液化炭酸ガスに溶解されてなる製剤が、耐圧容器に充填された防虫器具が記載されており、ゴキブリおよび蚊に対する殺虫効果が示されている。特許文献３には、殺虫剤等を溶解した液化炭酸ガスを充填した耐圧容器と特定の構造を有する配管とからなる殺虫殺菌装置が記載されている。 As a method for exterminating pests other than aerosol spraying, an instrument and an apparatus for spraying a drug dissolved in liquefied carbon dioxide gas are known. Patent Document 1 describes an insect repellent device in which an insecticidal component is dissolved in liquefied carbon dioxide gas, and shows an insecticidal effect against cockroaches. Patent Document 2 describes an insect repellent device in which a preparation in which an active ingredient is dissolved in liquefied carbon dioxide gas is filled in a pressure resistant container, and shows an insecticidal effect against cockroaches and mosquitoes. Patent Document 3 describes an insecticidal sterilizer comprising a pressure-resistant container filled with liquefied carbon dioxide dissolved with an insecticide and the like and a pipe having a specific structure.
しかし、特許文献１〜３に記載の方法は、いずれも蚊やゴキブリなどを対象としているため、薬剤散布量も多く、また、通常これらとは棲息域の異なるトコジラミを対象として使用されることは考えられなかった。 However, since all of the methods described in Patent Documents 1 to 3 are directed to mosquitoes and cockroaches, the amount of drug spraying is large, and it is usually used for bed bugs with different habitats. I could n’t think of it.
本発明は、ヒトに対する吸血性および刺咬性の害虫であって、寝具や衣類の縫い目、カーペットなどの人の目に触れにくい場所で棲息、繁殖するトコジラミの駆除に好適な技術を提供するものである。 The present invention provides a technique suitable for extermination of bed bugs that are blood-sucking and biting pests on humans and that live and breed in places where it is difficult to touch human eyes such as bedding and clothing seams, carpets, etc. It is.
本発明のトコジラミの駆除方法は、液化炭酸ガスに溶解したα−シアノ−３−フェノキシベンジルクリサンテマートを含む殺虫用組成物が加圧充填されている耐圧容器から、室内でのα−シアノ−３−フェノキシベンジルクリサンテマートの濃度が０．１〜２．５ｍｇ／ｍ３の範囲内になるように、該殺虫用組成物を噴射する工程を包含することを特徴としている。 The method for extermination of bed bugs according to the present invention is carried out from a pressure-resistant container filled with an insecticidal composition containing α-cyano-3-phenoxybenzylchrysantemate dissolved in liquefied carbon dioxide gas, from an indoor α-cyano- It includes a step of spraying the insecticidal composition so that the concentration of 3-phenoxybenzylchrysanthemate is in the range of 0.1 to 2.5 mg / m 3 .
本発明の方法は、上記濃度を３０分間以上にわたって維持する工程をさらに包含することが好ましい。また、α−シアノ−３−フェノキシベンジルクリサンテマートは、上記殺虫用組成物中の濃度が０．０００１〜１．５重量％の範囲内であることが好ましい。 It is preferable that the method of the present invention further includes a step of maintaining the above concentration for 30 minutes or more. Moreover, it is preferable that the density | concentration in the said insecticidal composition is (alpha)-cyano-3- phenoxy benzyl chrysanthemate within the range of 0.0001 to 1.5 weight%.
本発明の方法において、上記殺虫用組成物は、α−シアノ−３−フェノキシベンジルクリサンテマートの効力を増強させる因子をさらに含んでいてもよく、上記因子としては、α−シアノ−３−フェノキシベンジルクリサンテマートが有する殺虫力を増強する働きを有する物質であれば、特に限定されず、例えば、Ｎ−（２−エチルヘキシル）−ビシクロ［２，２，１］ヘプト−５−エン−２，３−ジカルボキシイミド（以下、「ＭＧＫ−２６４」）、チオシアノ酢酸イソボルニル（以下、「ＩＢＴＡ」）、ピベロニルブトキサイド（以下、「ＰＢＯ」）等が挙げられる。 In the method of the present invention, the insecticidal composition may further contain a factor that enhances the efficacy of α-cyano-3-phenoxybenzylchrysanthemate, and the factor includes α-cyano-3-phenoxy. The substance is not particularly limited as long as it has a function of enhancing the insecticidal power of benzylchrysanthemate. For example, N- (2-ethylhexyl) -bicyclo [2,2,1] hept-5-ene-2, 3-dicarboximide (hereinafter “MGK-264”), isobornyl thiocyanoacetate (hereinafter “IBTA”), piveronyl butoxide (hereinafter “PBO”) and the like.
本発明の方法において、上記殺虫用組成物は、溶剤を用いることなく、α−シアノ−３−フェノキシベンジルクリサンテマートを液化炭酸ガスに直接溶解して生成されていることが好ましく、この場合、本発明の方法は、α−シアノ−３−フェノキシベンジルクリサンテマートを液化炭酸ガスに直接溶解して殺虫用組成物を調製する工程をさらに包含してもよい。また、本発明の方法は、殺虫用組成物を耐圧容器内に加圧充填する工程をさらに包含してもよい。 In the method of the present invention, the insecticidal composition is preferably produced by directly dissolving α-cyano-3-phenoxybenzylchrysanthemate in liquefied carbon dioxide gas without using a solvent. The method of the present invention may further include a step of preparing an insecticidal composition by directly dissolving α-cyano-3-phenoxybenzylchrysanthemate in liquefied carbon dioxide gas. The method of the present invention may further include a step of pressurizing and filling the insecticidal composition into the pressure resistant container.
また、本発明は、直接に殺虫剤を噴霧できないような狭い隙間に棲息しているトコジラミに対しても有効に駆除できる方法を提供する。 In addition, the present invention provides a method that can be effectively exterminated against bed bugs that live in narrow gaps where insecticides cannot be sprayed directly.
本発明の方法によれば、ヒトに対する吸血性および刺咬性の害虫であって、寝具や衣類の縫い目、カーペットなどの人の目に触れにくい、隠れた場所で棲息、繁殖するトコジラミを駆除することができる。 According to the method of the present invention, the insects that are blood-sucking and biting pests on human beings, which are difficult to touch human eyes such as bedding and clothing seams, carpets, etc. be able to.
本発明の実施の形態について以下のように説明するが、本発明はこれに限定されるものではない。 Embodiments of the present invention will be described as follows, but the present invention is not limited thereto.
本発明は、トコジラミを駆除する方法を提供する。トコジラミはトコジラミ科に属し、世界中に広く分布している、体長約５ｍｍの昆虫である。形状は赤褐色の扁平な卵円形であり、尖った管状の口は吸血に適している。主として人家内の寝具や衣類の縫い目、カーペットなどの人の目に触れにくい、隠れた場所に棲息し、夜間に活発に活動し、ヒトの体表に一時的に接触して血を吸い、強いかゆみおよび痛みを生じさせる。 The present invention provides a method for combating bed bugs. Bed bugs are insects of about 5 mm in length, which belong to the bed bug family and are widely distributed throughout the world. The shape is a reddish brown flat oval shape, and the pointed tubular mouth is suitable for blood sucking. It is mainly hard to touch people's eyes such as bedding, clothing seams, carpets, etc., inhabiting hidden places, actively working at night, and temporarily touching the human body surface to suck blood and strong Causes itching and pain.
本発明の方法は、液化炭酸ガス中にα−シアノ−３−フェノキシベンジルクリサンテマートが溶解されている殺虫用組成物を用いること、該組成物が耐圧容器内に加圧充填されていること、および室内にて該耐圧容器から該組成物を噴射して、該室内でのα−シアノ−３−フェノキシベンジルクリサンテマートの濃度を一定の範囲内にすることを特徴としている。 The method of the present invention uses an insecticidal composition in which α-cyano-3-phenoxybenzylchrysanthemate is dissolved in liquefied carbon dioxide gas, and the composition is pressurized and filled in a pressure resistant container. And the composition is sprayed from the pressure vessel in the room, so that the concentration of α-cyano-3-phenoxybenzylchrysanthemate in the room is within a certain range.
本発明の方法において、上記組成物は、溶剤を用いることなく、α−シアノ−３−フェノキシベンジルクリサンテマートを液化炭酸ガスに直接溶解して生成されていることが好ましく、この場合、本発明の方法は、α−シアノ−３−フェノキシベンジルクリサンテマートを液化炭酸ガスに直接溶解して殺虫用組成物を調製する工程をさらに包含してもよい。上記組成物は、例えば、鉄製またはアルミニウム製などの耐圧容器にα−シアノ−３−フェノキシベンジルクリサンテマートを入れ、さらに液化炭酸ガスを加圧充填することによって調製されてもよい。 In the method of the present invention, the composition is preferably produced by directly dissolving α-cyano-3-phenoxybenzylchrysanthemate in liquefied carbon dioxide gas without using a solvent. The method may further include a step of preparing an insecticidal composition by directly dissolving α-cyano-3-phenoxybenzylchrysanthemate in liquefied carbon dioxide gas. The composition may be prepared, for example, by placing α-cyano-3-phenoxybenzylchrysantemate in a pressure vessel such as iron or aluminum and further filling with liquefied carbon dioxide under pressure.
本発明の方法において、耐圧容器中に加圧充填されているα−シアノ−３−フェノキシベンジルクリサンテマートを溶解した液化炭酸ガスを噴霧した後の、室内でのα−シアノ−３−フェノキシベンジルクリサンテマートの室内濃度は、通常０．１〜１０．０ｍｇ／ｍ３の範囲内である。本発明におけるα−シアノ−３−フェノキシベンジルクリサンテマートの濃度範囲は、特許文献２にて用いられているものよりもはるかに低い。空間濃度をこの範囲内に調整することによって、ヒトの生活環境内に生息するトコジラミを駆除することができる。上記範囲は、好ましくは０．１〜２．５ｍｇ／ｍ３であり、より好ましくは０．５〜２．５ｍｇ／ｍ３であり得る。 In the method of the present invention, indoor α-cyano-3-phenoxybenzyl after spraying liquefied carbon dioxide gas in which α-cyano-3-phenoxybenzylchrysanthemate dissolved under pressure in a pressure vessel is sprayed The indoor concentration of chrysanthemate is usually in the range of 0.1 to 10.0 mg / m 3 . The concentration range of α-cyano-3-phenoxybenzylchrysanthemate in the present invention is much lower than that used in Patent Document 2. By adjusting the spatial concentration within this range, bed bugs that live in the human living environment can be controlled. The above range is preferably 0.1 to 2.5 mg / m 3 , more preferably 0.5 to 2.5 mg / m 3 .
本発明の方法において、耐圧容器内における液化炭酸ガス中のα−シアノ−３−フェノキシベンジルクリサンテマートの含有量（重量割合）は０．０００１重量％以上であることが必要であり、上限はその溶解度量以下であれば制限されないが、一般的には１．５重量％である。 In the method of the present invention, the content (weight ratio) of α-cyano-3-phenoxybenzylchrysanthemate in the liquefied carbon dioxide gas in the pressure vessel must be 0.0001% by weight or more, and the upper limit is Although it will not restrict | limit if it is below the solubility amount, Generally it is 1.5 weight%.
本発明の方法において、室内でのα−シアノ−３−フェノキシベンジルクリサンテマートの空間濃度を上記した範囲とするためには、上記した耐圧容器内における液化炭酸ガス中のα−シアノ−３−フェノキシベンジルクリサンテマートの含有量（重量割合）および室内空間の広さに応じて、耐圧容器からの液化炭酸ガスの噴射量を適宜調整すればよい。 In the method of the present invention, in order to make the spatial concentration of α-cyano-3-phenoxybenzylchrysanthemate indoors within the above range, α-cyano-3-in liquefied carbon dioxide gas in the pressure vessel described above. What is necessary is just to adjust suitably the injection quantity of the liquefied carbon dioxide gas from a pressure-resistant container according to content (weight ratio) of phenoxy benzyl chrysanthemate, and the width of indoor space.
また、本発明の方法において、殺虫用組成物を噴射した後は、室内を可能な限り密閉することが好ましい。室内を密閉することによって、室内でのα−シアノ−３−フェノキシベンジルクリサンテマートの濃度をできるだけ維持し、殺虫効果を増強することができる。室内を密閉する時間は、３０分間以上であればよいが、１時間以上がより好ましい。もちろん、長時間であればあるほど殺虫効果は高まるが、不必要に長時間にわたって密閉する必要はなく、長くでも一日以内であれば十分である。 In the method of the present invention, it is preferable to seal the room as much as possible after spraying the insecticidal composition. By sealing the room, the concentration of α-cyano-3-phenoxybenzylchrysantemate in the room can be maintained as much as possible to enhance the insecticidal effect. The time for sealing the room may be 30 minutes or more, but more preferably 1 hour or more. Of course, the longer the time is, the higher the insecticidal effect is. However, it is not necessary to seal it unnecessarily for a long time, and it is sufficient if it is within a day even if it is long.
本発明の方法において、調製が容易であるという観点から、本発明に用いられる殺虫用組成物は、液化炭酸ガス中にα−シアノ−３−フェノキシベンジルクリサンテマートのみを含んでいることが好ましいが、殺虫用組成物は、α−シアノ−３−フェノキシベンジルクリサンテマートの効力を増強させる因子をさらに含んでいてもよく、上記因子としては、上記化合物が有する殺虫力を増強する働きを有する物質であれば、特に限定されず、例えば、Ｎ−（２−エチルヘキシル）−ビシクロ［２，２，１］ヘプト−５−エン−２，３−ジカルボキシイミド（以下、「ＭＧＫ−２６４」）、チオシアノ酢酸イソボルニル（以下、「ＩＢＴＡ」）、ピベロニルブトキサイド（以下、「ＰＢＯ」）等が挙げられる。 In the method of the present invention, from the viewpoint of easy preparation, the insecticidal composition used in the present invention preferably contains only α-cyano-3-phenoxybenzylchrysanthemate in the liquefied carbon dioxide gas. However, the insecticidal composition may further contain a factor that enhances the efficacy of α-cyano-3-phenoxybenzylchrysantemate, and the factor has a function of enhancing the insecticidal power of the compound. If it is a substance, it will not specifically limit, For example, N- (2-ethylhexyl) -bicyclo [2,2,1] hept-5-ene-2,3-dicarboximide (henceforth "MGK-264") , Isobornyl thiocyanoacetate (hereinafter “IBTA”), piveronyl butoxide (hereinafter “PBO”), and the like.
上述した方法を実現するための構成を備えているキットもまた、本発明の範囲に含まれる。すなわち、本発明は、トコジラミを駆除するためのキットを提供する。本発明のキットは、α−シアノ−３−フェノキシベンジルクリサンテマートおよび液化炭酸ガスを備えており、これらを充填する耐圧容器をさらに備えていることが好ましい。 A kit having a configuration for realizing the above-described method is also included in the scope of the present invention. That is, the present invention provides a kit for combating bed bugs. The kit of the present invention includes α-cyano-3-phenoxybenzylchrysanthemate and liquefied carbon dioxide gas, and preferably further includes a pressure-resistant container filled with these.
α−シアノ−３−フェノキシベンジルクリサンテマートを溶解した液化炭酸ガスを噴霧する空間と十分繋がっていない狭い隙間に棲息しているトコジラミに対しても本発明の駆除方法を実施することにより、上記隙間に薬剤が浸透して効果を発揮するが、薬剤の空間濃度が同じ場合であっても、例えば液化炭酸ガス中のα−シアノ−３−フェノキシベンジルクリサンテマートの含有量を低くして、α−シアノ−３−フェノキシベンジルクリサンテマートを溶解した液化炭酸ガスの噴霧量を多くして、噴霧空間内の炭酸ガス濃度を高めることにより、上記隙間からトコジラミが炭酸ガス濃度の高い空間、すなわちα−シアノ−３−フェノキシベンジルクリサンテマートを溶解した液化炭酸ガスを噴霧した空間に、移動してきて殺虫有効成分に暴露され易くなり効果の発現がより速く、かつ確実となる。 By carrying out the extermination method of the present invention also for bed bugs living in a narrow gap that is not sufficiently connected to the space sprayed with liquefied carbon dioxide gas in which α-cyano-3-phenoxybenzylchrysanthemate is dissolved, The drug penetrates into the gap and exerts the effect, but even if the spatial concentration of the drug is the same, for example, the content of α-cyano-3-phenoxybenzylchrysanthemate in the liquefied carbon dioxide gas is reduced, By increasing the spray amount of the liquefied carbon dioxide gas in which α-cyano-3-phenoxybenzylchrysanthemate is dissolved and increasing the carbon dioxide gas concentration in the spray space, the bed bug is a space where the carbon dioxide gas concentration is high from the gap, that is, It moves to the space sprayed with liquefied carbon dioxide gas in which α-cyano-3-phenoxybenzylchrysanthemate is dissolved and exposed to the insecticidal active ingredient. Expression of tends effect Re becomes faster, and reliable.
