Abstract

2,2,3,3-Tetramethylcyclopropanecarboxylic acid fluorine-substituted-benzyl esters of the formula ##STR1## in which R.sup.1 is hydrogen, cyano, or alkyl, alkenyl or alkynyl each with up to 4 carbon atoms, and PA0 R.sup.2 is a phenyl radical which is substituted by halogen and/or by optionally halogen-substituted phenoxy, with the proviso that the radical R.sup.2 in total contains at least one fluorine substituent, which possess insecticidal and acaricidal properties.
