In contrast to that, the result was completely unexpected. Further, in the case of d, d-T80-praletrin (Comparative Examples 5 and 6) in which the vapor pressure of the pyrethroid insecticidal component is out of the range of the present invention, the insecticidal efficacy enhancing effect observed in 1,2-hexanediol was observed.
- the efficacy-enhancing effect peculiar to the present invention is an extremely heterogeneous effect that is exhibited only when combined with a pyrethroid insecticidal component in a specific vapor pressure range. Furthermore, even when an oil-based formulation was used instead of an aqueous formulation (Comparative Example 7), a sufficient insecticidal effect was not obtained.
- the present invention can be used as a pest control product for humans and pets, but it can also be used for other purposes such as acaricidal, sterilizing, antibacterial, deodorizing, and deodorizing. ..

本発明で用いる加熱蒸散用水性殺虫剤組成物は、水性処方とするため溶媒として水が使用され、さらにピレスロイド系殺虫成分を可溶化させるために水性有機化合物が配合される。このように水性処方とすることで、油性処方に比べて火気に対する危険性を軽減することができ、害虫に対する殺虫効果は同等以上であると言われている。水性処方となすために配合される水性有機化合物は、(1)ピレスロイド系殺虫成分を可溶化できること、(2)加熱蒸散性を有すること、(3)ピレスロイド系殺虫成分と水との間に介在して3成分が一定の比率を保って加熱蒸散すること、を前提とするものである。本発明では、殺虫効力増強剤として機能するグリコール系化合物は、ピレスロイド系殺虫成分に対する可溶化能等に応じて、水性有機化合物の一部又は全部となるように配合してもよい。また、当該グリコール系化合物とともに、他の化合物、例えばグリコールエーテル系化合物を併用することで、水性有機化合物を構成してもよい。グリコールエーテル系化合物は、ピレスロイド系殺虫成分の可溶化能や加熱蒸散性に優れ、特許文献1や特許文献2においては主要な水性有機化合物(界面活性剤あるいは水性有機溶剤とも称される)として示されている。本発明においても、グリコールエーテル系化合物は、グリコール系化合物の補完成分として有用なものである。
グリコールエーテル系化合物としては、沸点が150~300℃のものが好ましく、170~260℃のものがより好ましい。かかるグリコールエーテル系化合物として、例えば、ジエチレングリコールモノエチルエーテル(沸点:202℃、以降DEME)、ジエチレングリコールモノイソプロピルエーテル(沸点:207℃、以降DEMIP)、ジエチレングリコールモノブチルエーテル(沸点:231℃、以降DEMB)、ジエチレングリコールモノイソブチルエーテル(沸点:220℃、以降DEMIB)、ジエチレングリコールモノヘキシルエーテル(沸点:259℃、以降DEMH)、ジエチレングリコールモノ2-エチルヘキシルエーテル(沸点:272℃)、ジエチレングリコールモノフェニルエーテル(沸点:283℃)、トリエチレングリコールモノメチルエーテル(沸点:249℃)、プロピレングリコールモノターシャリーブチルエーテル(沸点:151℃)、ジプロピレングリコールモノメチルエーテル(沸点:188℃)、ジプロピレングリコールモノプロピルエーテル(沸点:210℃、以降DPMP)、3-メトキシ-1,2-プロパンジオール(沸点:220℃)、及び3-メトキシ-3-メチルブタノール(沸点:174℃、以降ソルフィット)等が挙げられる。これらのグリコールエーテル系化合物のうち、ジエチレングリコールモノエチルエーテル、ジエチレングリコールモノイソプロピルエーテル、ジエチレングリコールモノブチルエーテル、ジエチレングリコールモノイソブチルエーテル、ジエチレングリコールモノヘキシルエーテル、ジプロピレングリコールモノメチルエーテル、ジプロピレングリコールモノプロピルエーテル、及び3-メトキシ-3-メチルブタノールが好適である。上掲のグリコールエーテル系化合物は、単独で使用してもよいし、複数種を混合した状態で使用してもよい。
上記のように調製された加熱蒸散用水性殺虫剤組成物は、加熱蒸散用吸液芯を備えた容器本体(図示せず)に充填され、害虫防除製品(液体式蚊取)を構成する。すなわち、加熱蒸散用水性殺虫剤組成物に加熱蒸散用吸液芯を浸漬し、吸液された加熱蒸散用水性殺虫剤組成物を加熱蒸散用吸液芯の上部に導き、80~150℃で加熱することにより、ピレスロイド系殺虫成分を大気中に蒸散させる害虫防除方法に適用されるのである。
ところで、液体式蚊取の加熱蒸散用吸液芯は、一般的な区分けによれば、焼成芯、多孔質セラミック芯、フェルト芯、製紐芯、粘結芯に大別されるが、本発明では、焼成芯、多孔質セラミック芯、フェルト芯、製紐芯が好適に使用され、より好適には焼成芯又は多孔質セラミック芯が使用される。以下、加熱蒸散用吸液芯として焼成芯又は製紐芯を使用する場合について、説明する。なお、加熱蒸散用吸液芯の素材は、ピレスロイド系殺虫成分を含む加熱蒸散用水性殺虫剤組成物に対して安定で、且つ毛細管現象で水溶液を吸液可能なものであれば、特に限定されない。
<加熱蒸散用水性殺虫剤組成物>
ピレスロイド系殺虫成分としてのトランスフルトリンを0.9質量%、殺虫効力増強剤としてのグリコール系化合物である1,2-ヘキサンジオールを40質量%、水性有機化合物としての3-メトキシ-3-メチルブタノール(ソルフィット)を10質量%、安定剤としてジブチルヒドロキシトルエン(BHT)を0.1質量%、及び精製水を49質量%配合し、加熱蒸散用水性殺虫剤組成物を調製した。
無機質粉体としてマイカ粉を52質量%、無機質粘結剤としてクレー粉を33質量%、有機物質として黒鉛を10質量%、有機質粘結剤としてカルボキシメチルセルロースを3質量%、澱粉を2質量%含む混合物に水を加えて混練し、混錬物を加圧しながら押出し、風乾した後、1100℃で焼成し、加熱蒸散用吸液芯(直径7mm、長さ66mmの丸棒)を得た。
加熱蒸散用水性殺虫剤組成物45mLをプラスチック製容器に収容し、中栓を介して加熱蒸散用吸液芯を装填したのち、加熱蒸散装置[例えば、特許第2926172号に記載の加熱蒸散装置、吸液芯の上部の周囲に中空筒状の放熱筒体(内径:10mm、高さ:10mm、表面温度:137℃)を設置]に取り付け、実施例1の害虫防除製品とした。なお、放熱筒体の内壁に対向する加熱蒸散用吸液芯の上部の長さは放熱筒体の内壁の高さの0.7倍であった。
実施例1の害虫防除製品を6畳の部屋(25m3)の中央に置き、四方側面の一つが屋外に面した窓を開放した状態で1日あたり12時間通電使用したところ、60日間(約700時間)にわたり、蚊が窓から屋内に侵入して人を刺咬することはなかった。
実施例1に準じて、加熱蒸散用水性殺虫剤組成物及び加熱蒸散用吸液芯を調製し、これらを加熱蒸散装置に装填して実施例2~16の害虫防除製品を作製した。このうち、実施例2~15の各害虫防除製品について、後述する(1)~(3)の測定及び試験を実施した。また、比較のために作製した比較例1~6の害虫防除製品についても、実施例と同様の測定及び試験を実施した。各実施例及び比較例における加熱蒸散用水性殺虫剤組成物の処方、及び加熱蒸散用吸液芯の配合を表1~2に分けて示す。なお、表1には実施例1の加熱蒸散用水性殺虫剤組成物の処方、及び加熱蒸散用吸液芯の配合についても記載する。
水性処方の殺虫剤組成物との比較のため、油性処方の殺虫剤組成物を調製した。具体的には、比較例1の加熱蒸散用水性殺虫剤組成物において、水性有機化合物(グリコール系化合物及びグリコールエーテル系化合物)を含まないものを調製し、さらに水の代わりに灯油(ケロシン)を使用して油性処方の殺虫剤組成物(加熱蒸散用油性殺虫剤組成物)を得た。加熱蒸散用油性殺虫剤組成物の蒸散に用いる加熱蒸散用吸液芯は、比較例1と同じ組成の焼成芯を使用し、これを加熱蒸散装置に装填して比較例7の害虫防除製品とした。比較例7の害虫防除製品についても、実施例と同様の測定及び試験を実施した。
6畳の部屋(25m3)の中央に供試害虫防除製品を置き、通電加熱した。使用初期(使用日数2日目)に、加熱蒸散装置から上方1m離れた位置でシリカゲル充填カラムを用いて蒸散粒子をトラップし、アセトンで殺虫成分を抽出後、ガスクロマトグラフ分析により単位時間当たりの殺虫成分の蒸散量を求めた。
内径20cm、高さ43cmのプラスチック製円筒を2段に重ね、その上に16メッシュの金網を介して内径20cm、高さ20cmの円筒(供試昆虫を入れる場所)を載せ、その上を同じ16メッシュの金網で仕切り、さらにその上に同径で高さ20cmの円筒を載せた。この4段重ねの円筒を台に載せた円板上にゴムパッキンを挟んで置いた。円板中央には5cmの円孔があり、この円孔の上に供試害虫防除製品を置き、通電加熱した。通電3時間後、上部3段目の円筒に供試昆虫のアカイエカ雌成虫約20匹を放った。時間経過に伴い落下仰転した供試昆虫を数え、KT50値を求めた。また、暴露20分後に全供試昆虫を回収して24時間後にそれらの致死率を調べた。殺虫効力試験は、使用初期(使用日数2日目)及び使用後期(有効期限の数日前)について実施した。
隣接する10畳の2居室の境界に窓を設け、窓以外は密閉した。一方の居室に供試害虫防除製品を置き、観察者が室内に留まるとともに通電加熱して薬剤処理区とした。隣接する無薬放虫区に供試昆虫のアカイエカ雌成虫100匹を放ち、窓を通って無薬放虫区から薬剤処理区に侵入する供試虫数を60分間観察した。また、効果判定の基準を設けるため、無処理対照区として害虫防除製品を使用しない試験を同様に実施した。侵入阻止試験は、供試害虫防除製品の使用初期(使用日数2日目)及び使用後期(有効期限の数日前)について2回繰返して実施した。無処理対照区についても同様に2回繰返し試験を行い、平均侵入虫数を求め、以下の式より侵入阻止率を算出した。
侵入阻止率(%) = (C-T)/C × 100
C:無処理対照区の60分間の平均侵入虫数(匹)
T:薬剤処理区の60分間の平均侵入虫数(匹)
