In addition, compositions comprising an insecticidally effective amount of at least one compound of formula (I), and optionally, an effective amount of at least one of a second compound, with at least one insecticidally compatible carrier are also disclosed; along with methods of controlling insects comprising applying said compositions to a locus where insects are present or are expected to be present.
现在已经发现了某些新型杂环衍
生物具有出乎意料的杀虫活性。这些化合物由公式(I)表示:R。其中,首选的是公式(I)中R2和R3结合成═NCH(R6)CH(R7)N(R8)—、═NC(R6)=C(R7)N(R8)-或═CHN═C(R7)N(R8)—,以及其互变异构体,且其中R4和R5结合成—C(R11)=C(R12)C(R13)=C(R14)112,-,其中描述了R、R、R6、R7、R8、R11、R R13、R14和X。此外,还公开了包含公式(I)中至少一种化合物的杀虫有效量,以及可选地,至少一种第二化合物的有效量,与至少一种杀虫兼容载体的组合物;以及控制昆虫的方法,包括将所述组合物应用于昆虫存在或预计存在的地点。
