This invention relates to new pyridine derivatives represented by general formula (I) and their salts, and also an insecticidal/acaricidal agent containing the same as the active ingredient. In said formula, R1 represents a C2 to C20 straight-chain, branched or cyclic alkyl, alkenyl or alkynyl group which may be substituted by a substituent containing halogen, oxygen, sulfur or nitrogen; R2 represents a C, to C6 straight-chain, branched or cyclic alkyl, alkenyl or alkynyl group, provided that R1 has at least four carbon atoms in total, R1 is different from R2, and part of R1 and R2 are each methylene and together form a C4 to C8 cyclic structure; and R3 represents hydrogen or a C1 to C6 straight-chain or branched alkyl group.
本发明涉及通式(I)代表的新吡啶衍生物及其盐类,以及以其为活性成分的杀虫/杀螨剂。在所述通式中,R1 代表 C2 至 C20 直链、支链或环状烷基、烯基或炔基,可被含卤素、氧、硫或氮的取代基取代;R2 代表 C、C6 直链、支链或环状烷基、烯基或炔基,条件是 R1 总共至少有四个碳原子,R1 与 R2 不同,且 R1 和 R2 的一部分各自为亚甲基并共同形成 C4 至 C8 环状结构;以及 R3 代表氢或 C1 至 C6 直链或支链烷基。
