The present invention relates to the use of N-(4-pyridyl)methylsulfonamides of the formula I for combating arthropodal pests (harmful arthropodes) and for protecting materials against infestation and/or destruction by said pests:where the substituents are as follows: Ris hydrogen, C-C-alkyl, C-C-alkoxy, C-C-alkenyl, C-C-alkynyl or benzyl; R, R, R, Rindependently of one another are hydrogen, halogen, C-C-alkyl, C-C-alkoxy, C-C-haloalkoxy or C-C-haloalkyl; Rand Ror Rand Rtogether with the carbon atoms to which they are attached may also form a condensed 5- or 6-membered hydro-carbon ring, it being possible for the hydrocarbon ring to carry one or two groups R', R', R', R' independently of one another are halogen, C-C-alkyl, C-C-alkoxy, halomethoxy or halomethyl; X is a cyclic radical selected from phenyl, naphthyl and five- or six-membered saturated, partially unsaturated or aromatic heterocycles, the heterocycle being attached to the sulfur atom via a carbon atom and containing 1 , 2 or 4 heteroatoms selected from the group consisting of O, N and S, where the cyclic radical X may carry 1 , 2, 3 or 4 substituents R. |
