FIELD: chemistry.SUBSTANCE: invention relates to organic chemistry, specifically to a novel heterocyclic compound of general formula (1) or N-oxide thereof, where A1: -NR7-, O or S, A2: =CR8-, A3: N or =CR9-, R1 is C1-C4 alkyl, optionally substituted with 3 atoms or Groups X, or C3-C6 cycloalkyl group, R2, R3 and R4 are identical or differ from each other and each denotes C1-C2 alkyl optionally substituted with 3–5 atoms or Groups X, 6-member heterocycle -OR10, -NR10C(O)R11, cyano group, a halogen atom or a hydrogen atom, R5 and R6 are identical or differ from each other and each denotes C1-C6 alkyl substituted with 3–5 atoms or Groups X, -OR10, -S(O)mR10, -CO2R10, -C(O)NR10R11, -SF5, cyano group, halogen atom or hydrogen atom (where R5 and R6 cannot simultaneously represent hydrogen atom), R7 represents C1-C6 alkyl, optionally substituted with 3 atoms or Groups W, C1-C6 alkyl, substituted with one phenyl group (where phenyl group is substituted with one atom or Group Z), C1-C6 alkyl substituted with one 5-member heterocycle (where 5-member heterocyclic group is thiazolyl, substituted with one atom or a group selected from Group Z), or a hydrogen atom, R8 and R9 are identical or differ from each other and each denotes C1-C6 alkyl substituted with 3 halogen atoms, -OR10, -S(O)mR10, -NR10R11, cyano group, a halogen atom or a hydrogen atom, R10 and R11 are identical or differ from each other and each denotes C1-C6 alkyl, optionally substituted with 3–5 atoms or Groups X, phenyl group, each m independently equals 0, 1 or 2 and n equals 0, 1 or 2, where in -S(O)mR10 R10 is different from a hydrogen atom, when m equals 1 or 2, Group X: C1-C6 alkoxy group, hydroxy group and a halogen atom, Group Z: C1-C6 alkoxy group, halogen atom, Group W: halogen atom. Invention also relates to a composition for pest control, a pest control method and intermediate compounds.EFFECT: obtaining novel compounds effective for pest control.24 cl, 71 tbl, 83 ex(1)Изобретение относится к области
