N-(4-Pyridyl)methylsulfonamides for combating arthropodal pests The present invention relates to the use of N-(4-pyridyl)methylsulfonamides of the formula for combating arthropodal pests (harmful arthropodes) and for protecting materials against infestation and/or destruction by said pests: (I) where the substituents are as follows: R 1 is hydrogen, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, C 2 -C 4 -alkenyl, C 2 -C 4 -alkynyl or benzyl; R 2 , R 3 , R 4 , R 5 independently of one another are hydrogen, halogen, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, C 1 -C 4 -haloalkoxy or C 1 -C 4 -haloalkyl; R 2 and R 3 or R 4 and R 5 together 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 2′ , R 3′ , R 2′ , R 3′ independently of one another are halogen, C 1 -C 4 -alkyl, C 1 -C 4 -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 a . |
