Use of compounds of formula (I) wherein Q is (II), (III), or (IV) ; X1 is chlorine, bromine, or fluorine; R1, R2 are each independently H, alkyl, alkenyl, alkynyl, or cycloalkyl, alkylamino, dialkylamino, alkylcarbonylamino, alkylsulfonyl, or alkylsulfinyl, wherein the carbon atoms in these groups may be substituted, or R1 and R2 may be taken together to form a ring represented by the structure (V); p,m are 1, 2 or 3; X' is oxygen, sulfur, amino, alkylamino, phenylamino, or methylene; Z is alkyl or phenyl; R3 is H, alkyl, alkenyl, alkynyl, cycloalkyl, wherein the carbon atoms in these groups may be substituted; R, R4 are H or alkyl, alkoxycarbonyl, alkylaminocarbonyl, or dialkylaminocarbonyl, wherein the carbon atoms in the these groups may be substituted; A is C-R5 or N; B is C-R6 or N; W is C-R7 or N; with the proviso that one of A, B and W is other than N; R5, R6, R7 are H, halogen, nitro, cyano, amino, mercapto, hydroxy, alkyl, alkenyl, alkynyl, cycloalkyl, alkoxy, alkylamino, dialkylamino, alkylthio, alkylsulfonyl, or alkylsulfinyl, wherein the carbon atoms in these groups may be substituted, a 5- to 6-membered aromatic ringsystem which may contain 1 to 4 heteroatoms selected from oxygen, sulfur and nitrogen and which may be substituted; Y is hydrogen, halogen, cyano, nitro, amino, hydroxy, mercapto, alkyl, alkenyl, alkynyl, cycloalkyl, alkoxy, alkylamino, dialkylamino, alkylthio, alkylsulfonyl, or alkylsulfinyl, wherein the carbon atoms in these groups may be substituted; n is 0, 1, or 2; for combating parasites in and on animals.

La présente invention a trait à l'utilisation de composés de formule (I), dans laquelle Q est (II), (III), ou (IV) : X?1 ¿est chlore, brome, ou fluor ; R?1¿, R?2¿ sont chacun indépendamment H, alkyle, alcényle, alcynyle, ou cycloalkyle, alkylamino, dialkylamino, alkylcarbonylamino, alkylsulfonyle, ou alkylsulfinyle, les atomes de carbone dans ces groupes pouvant être substitués, ou R?1¿ et R?2¿ ensemble peuvent former un noyau représenté par la structure V ; p, m sont 1, 2 ou 3 ; X' est oxygène, soufre, amino, alkylamino, phénylamino, ou methylène; Z est alkyle ou phényle ; R?3 ¿est H, alkyle, alcényle, alcynyle, cycloalkyle, les atomes de carbone dans ces groupes pouvant être substitués, R, R?4¿ sont H ou alkyle, alcoxycarbonyle, alkylaminocarbonyle, ou dialkylaminocarbonyle, les atomes de carbone dans ces groupes pouvant être substitués ; A est C-R?5¿ ou N; B est C-R?6¿ ou N; W est C-R?7¿ ou N ; à condition qu'un parmi A, B et W soit autre que N; R?5¿, R?6¿, R?7¿ sont H, halogène, nitro, cyano, amino, mercapto, hydroxy, alkyle, alcényle, alcynyle, cycloalkyle, alcoxy, alkylamino, dialkylamino, alkylthio, alkylsulfonyle, or alkylsulfinyle, les atomes de carbone dans ces groupes pouvant être substitués, un système de noyau aromatique de 5 à 6 chaînons pouvant contenir 1 à 4 hétéroatomes choisis parmi oxygène, soufre et azote et pouvant être substitués; Y est hydrogène, halogène, cyano, nitro, amino, hydroxy, mercapto, alkyle, alcényle, alcynyle, cycloalkyle, alcoxy, alkylamino, dialkylamino, alkylthio, alkylsulfonyle, ou alkylsulfinyle, les atomes de carbone dans ces groupes pouvant être substitués ; n est 0, 1, ou 2 pour la lutte contres des parasites chez ou sur des animaux.
