MEANS FOR COMBATING AN ETHOPARASIS OF ANIMALS AND METHOD FOR PREVENTING OR TREATING INFECTIOUS INFECTION CAUSED BY PARASITIS IN ANIMALS USING THE SPECIFIED MEANS FOR COMBATING INFECTIONS

摘要

1. An ectoparasite control agent for animals, comprising an N-pyridylpiperidine compound, its N-oxide or salts of these compounds, wherein said N-pyridylpiperidine compound is described by the formula (1): wherein R represents a halogen atom, a C haloalkyl group, a cyano group, a nitro group or a nitro group ; R, R, R, R, R, R, R, and R each represent a hydrogen atom or a C1-6 alkyl group; the groups in each of the R and R pairs, as well as R and R, may combine to form a C1-6 alkylene group; R represents a hydrogen atom; C1-6alkyl group; A cycloalkyl group; Alkenyl group; A alkynyl group; Haloalkyl group; Haloalkenyl group; C1-6alkylcarbonyl group; A alkoxycarbonyl group; a benzoyl group optionally substituted on the phenyl ring by one to five halogen atoms; a phenyl group optionally substituted on the phenyl ring by one or more substituents, each of which is independently selected from the group consisting of halogen, C 1-6 alkyl and C 1 haloalkyl; a heterocyclic group optionally substituted on the heterocyclic ring with one or more substituents, each of which is independently selected from the group consisting of halogen, C1-6alkyl, C1-6haloalkyl and optionally substituted heterocyclic groups; or a C1-6alkyl group optionally substituted with one or more substituents, each independently selected from the group consisting of Cycloalkyl optionally substituted with halogen, cyano, nitro, formyl, Calkoxy, Caloalkoxy, benzyloxy, phenoxy, -CON (R) (R), phenyl optionally substituted on the phenyl ring by one or more halogen atoms, and
