Fused heterocyclic compounds to which a heterocyclic ring is bonded or salts thereof, agricultural and horticultural insecticides containing the compounds, and methods of using the same
The present invention develops and provides new agricultural and horticultural insecticides due to factors such as the occurrence of pests resistant to existing drugs, because damage caused by pests is still large in agricultural and horticultural crop production. Is an issue. The present invention relates to a general formula (1) [Chemical 1] {In the formula, R 1 represents an ethyl group, R 2 represents a haloalkyl group, A 1 represents an N-methyl group, A 2 and A 3 represent a nitrogen atom, and n represents 1 And m represents 2. Q represents oxadiazole. } A condensed heterocyclic compound or a salt thereof to which a heterocyclic ring represented by the formula is bonded, an agricultural and horticultural insecticide containing the same as an active ingredient, and a method for using the same.本発明は、農業及び園芸等の作物生産において、害虫等による被害が今なお大きいことから、既存薬に対する抵抗性害虫の発生等の要因から新規な農園芸用殺虫剤を開発し、提供することを課題とする。 本発明は、一般式（１）【化１】｛式中、Ｒ1は、エチル基を示し、Ｒ２は、ハロアルキル基を示し、Ａ１は、Ｎ‐メチル基を示し、Ａ２、及びＡ３は、窒素原子を示し、ｎは、１を示し、ｍは、２を示す。Ｑは、オキサジアゾールを示す。}で表される複素環が結合した縮合複素環化合物又はその塩類、これを有効成分とする農園芸用殺虫剤並びにその使用方法を提供する。
