Compounds of the formula:
wherein
Ar is a pyridine, pyridazine, pyrimidine, pyrazine, isoquinoline or thiazole ring which, apart from the groups R' - S(O)x and -O-SO2 -R2, is unsubstituted or substituted by from I to 3 substituents selected from halogen, C, to C4- alkyl which is unsubstituted or substituted by halogen, C, to C4-alkoxy, CF3 and nitro;
R' is C, to C3-alkyl; C, to C7-alkyl which is substituted by from I to 3 F, CI or Br or by C, to C4-alkoxy or C, to C4- alkylthio; C3 to C7-cycloalkyl which is unsubstituted or substituted by from I to 4 F, Cl or methyl; C3 to C6- cycloalkylmethyl which is unsubstituted or substituted by from I to 4 F, Cl, Br or methyl; allyl; propargyl; phenyl or benzyl;
R' is C, to C4-alkyl which is unsubstituted or substituted by from I to 3 F or Cl;
x is 0, I or 2;
with the proviso that, when Ar is a pyridine ring which is substituted by R'-S(O)x and -O-SO2R2 at the 2-and 6- positions and R' is C, to C7-alkyl, the pyridine ring is further substituted as above but not by from I to 3 halogen atoms;
are useful for killing insect pests, acaridae and nematodes.

附带条件是,当 Ar 为吡啶环,在 2-和 6-位被 R'-S(O)x 和 -O-SO2R2 取代,且 R' 为 C,至 C7-烷基时,吡啶环进一步被上述取代,但不被 I 至 3 个卤原子取代;
可用于杀灭害虫、螨类和线虫。
