Sulfonamide derivatives represented by general formula (I) or salts thereof; insecticides for agricultural and horticultural use containing the same as the active ingredient; and usage thereof: n n[wherein A is optionally substituted (C 1 –C 6 )alkylene, (C 3 –C 6 )alkenylene or the like; R 1 is H, optionally substituted (C 1 –C 6 )alkyl, (C 3 –C 6 )alkenyl, (C 3 –C 6 )cycloalkyl or the like; R 2 , R 3 and R 4 are each H, (C 1 –C 6 )alkyl, (C 3 –C 6 )alkenyl or the like, or R 2 and A or R 2 and R 1 may form a 3- to 8-membered ring which may be interrupted by one to three atoms selected from among O, S and N; Q is C or N; X and Y are each halogen, CN, NO 2 , (C 1 –C 6 )alkyl, (C 2 –C 6 )alkenyl or the like; m is 0 to 2; n is 0 to 3; and two adjacent Xs or Ys on the aromatic ring may be united to form a fused ring]. The compounds exhibit excellent insecticidal activity against insect pests resistant to existing pesticides even when applied in dosages lower than those of similar pesticides. |
