Abstract

1-Aryl-cyclopropane-1-carboxylic acid esters of the formula ##STR1## in which R.sup.1 represents a hydrogen atom, a cyano radical or an alkyl, alkenyl or alkinyl radical within each case up to 7 carbon atoms, and PA1 R.sup.2 represents a phenyl radical which is substituted by halogen and/or optionally halogen-substituted phenoxy, with the proviso that the radical R.sup.2 in total contains at least one fluorine substituent, PA1 R.sup.3 and R.sup.4, which can be identical or different, represents a fluorine, chlorine or bromine atom or a methyl radical, PA1 R.sup.5 represents a hydrogen or halogen atom or a methyl or methoxy radical, and PA1 R.sup.6 represents a hydrogen or halogen atom, a cyano nitro or amino radical or an optionally halogen-substituted radical selected from C.sub.1 to C.sub.4 alkyl, C.sub.1 to C.sub.4 alkoxy and C.sub.1 to C.sub.4 alkylthio, or wherein PA1 the two radicals R.sup.5 and R.sup.6 together represent an optionally halogen-substituted C.sub.1 or C.sub.2 alkylenedioxy radical, which possess pesticidal properties.
