実施例18-アセトフェノンと組み合わせた各種油の残留活性
本実施例は、極性芳香族溶媒としてのアセトフェノンと殺虫性天然油(タイム油、ガーリック油及びニーム油)をさらに備える配合物の乾燥残留殺虫活性を示す。溶液は、5.5重量%のニーム油、重量で表19に示す%の有機溶媒、及びキャリア希釈液としての適量のイソプロパノールにより調製した。溶媒は、最終的な濃度が1.5mol/kgとなるように加えられた。溶液としてまた、各天然油単独(重量で5.5%でありキャリア希釈液としての適量のイソプロパノールを有する)のもの、及び極性芳香族溶媒単独のもの(重量で表19に示す%でありキャリア希釈液としての適量のイソプロパノールを有する)を調製した。各溶液の投与群は、直径90ミリの濾紙に1.0mLの溶液を投与し、4時間空気乾燥することにより調製した。既知数の成虫(通常は10)を、投与後4時間で、投与した各ペトリ皿に加えた。トコジラミの死亡率は、寄生直後及び寄生後1時間、2時間、4時間、6時間、8時間、10時間、12時間及び24時間の間隔で、その後は24時間間隔で寄生後14日まで評価した。刺激によって反応しなかった場合の成虫トコジラミを死んだものとしてカウントした。表19は、全ての投与群の最大死亡率%及び最大死亡率の到達に要した時間を示す。殺虫性天然油及びアセトフェノンの組み合わせは、殺虫性天然油又はアセトフェノン単独のそれぞれよりもより効果的であった。
