The present invention relates to the use of N- (4-pyridyl) methylsulfonamides of the formula I for the control of arthropod pests (harmful arthropods) and for the protection of materials from attack and / or destruction by these pests, in which the substituents take on the following meanings: R is hydrogen, C-C-alkyl , C -C-alkoxy, C -C-alkenyl, C -C-alkynyl or benzyl; R, R; R, R independently of one another are hydrogen, halogen, C -C alkyl, C -C alkoxy, C -C haloalkoxy or C -C haloalkyl; R and R or R and R, together with the carbon atoms to which they are attached, can also form a fused 5- or 6-membered hydrocarbon ring, wherein the hydrocarbon ring can carry one or two groups R ', R', R ', R' independently of each other mean halogen, C -C-alkyl, C -C-alkoxy, halomethoxy or halomethyl; X denotes a cyclic radical selected from phenyl, naphthyl and five- or six-membered saturated, partially unsaturated or aromatic heterocycles, where the heterocycle is attached to the sulfur atom via a carbon atom and contains 1, 2 or 4 heteroatoms selected from the group consisting of O, N and S, wherein the cyclic radical X can carry 1, 2, 3 or 4 substituents R. |
