PROBLEM TO BE SOLVED: To provide a composition useful for pest controlling insects, especially useful for pest controlling aphid and other sucking insects.SOLUTION: Stereochemical stability of an N-substituted (6-haloalkylpyridin-3-yl)alkylsulfoximine compound represented by a formula and exhibiting insecticidal activity is enhanced by adding organic acid such as citric acid, tartaric acid and lactic acid or a slat thereof. In the formula, X is NO2, CN or COOR4, R1 is (C1 to C4) alkyl, R2 and R3 are each independently H, methyl, ethyl, F, Cl or Br, Y is (C1 to C4)haloalkyl, F, Cl, Br or I and R4 is (C1 to C3)alkyl.SELECTED DRAWING: None |
