The present invention relates to N- (4-pyridyl) methylsulfonamide for controlling arthropod pests. The present invention relates to the use of N- (4-pyridyl) methylsulfonamide of formula (I) for controlling arthropod pests (harmful arthropods) and protecting the material against invasion and / or destruction by said pests. .n n n <Formula I>n n n n n n n n Wherein 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 are independently of each other 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 form a 5- or 6-membered hydrocarbon ring, said hydrocarbon ring having one or two R 2 ′ , R 3 ′ groups R 2 ′ , R 3 ′ are independently of each other halogen, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, halomethoxy or halomethyl; X is a cyclic radical selected from phenyl, naphthyl and 5- or 6-membered saturated, partially unsaturated or aromatic heterocycles which are attached to sulfur atoms via carbon atoms and consist of O, N and S Containing 1, 2 or 4 heteroatoms selected from the group, said cyclic radicals X may have 1, 2, 3 or 4 substituents R a . |
