ABSTRACT:
The present invention relates to agents for systemic combating of ectoperasites in host animals, containing a compound of the formul I ##STR1## in which R.sup.1 denotes hydrogen, (C.sub.1 -C.sub.5)-alkyl, (C.sub.1 -C.sub.3)-halogenoalkyl or halogen;
R.sup.2 and R.sup.3 independently of one another denote (c.sub.1 -C.sub.5)-alkyl, (C.sub.2 -C.sub.5)-alkenyl, (C.sub.2 -C.sub.5)-alkynyl, (C.sub.3 -C.sub.7)-cycloalkyl, (C.sub.3 -C.sub.7)-cycloalkenyl, (C.sub.1 -C.sub.3)-halogenoalkyl, halogen, cyano, nitro, (C.sub.1 -C.sub.5)-alkoxy, (C.sub.1 -C.sub.3)-alkoxy-C.sub.1 -C.sub.3)-alkyl, (C.sub.1 -C.sub.3)-halogenoalkoxy or (C.sub.1 -C.sub.3)-alkylthio, or R.sup.2 and R.sup.3 together form a polymethylene chain having 2 to 5 carbon atoms:
