PROBLEM TO BE SOLVED: To provide a constitution of a mosquito or fly repelling incense stick adopting a more useful potentiating agent based on a power potentiating effect of an Exo type and an Endo type in the mosquito or fly repelling incense stick containing N-(2-ethylhexyl)-bicyclo[2,2,1]-hepta-5-ene-2,3-dicarboximide (power potentiating agent A) together with pyrethroid.SOLUTION: The mosquito or fly repelling incense stick is based on compounding the power potentiating agent having an Exo type ratio of 70% or more and an Endo type ratio of 30% or less of N-(2-ethylhexyl)-bicyclo[2,2,1]-hepta-5-ene-2,3-dicarboximide with an insecticidal ingredient at an amount of 0.5 times or more, preferably at an amount of 1.0-5.0 times the ingredient amount.COPYRIGHT: (C)2013,JPO&INPIT【課題】ピレスロイドとともにN-(2-エチルヘキシル)-ビシクロ[2,2,1]-ヘプタ-5-エン-2,3-ジカルボキシイミド(効力増強剤A)を含有する蚊又はハエ取り線香において、Exo型とEndo型の効力増強効果に基づくより有用な増強剤を採用した蚊又はハエ取り線香の構成を提供すること。【解決手段】N-(2-エチルヘキシル)-ビシクロ[2,2,1]-ヘプタ-5-エン-2,3-ジカルボキシイミドのExo型比率が70%以上で、Endo型比率が30%以下である効力増強剤を殺虫成分量に対し0.5倍量以上、好ましくは1.0~5.0倍量配合したことに基づく蚊又はハエ取り線香。【選択図】なし
