ABSTRACT:
Carboxylic acid esters of the formula (I), ##STR1## wherein X is a hydrogen atom, or a C.sub.1 -C.sub.3 alkyl or a C.sub.1 -C.sub.3 alkoxyl group or a halogen atom linked to the meta or para position and R.sub.1 is a group of the formula (II) or (III), ##STR2## wherein R.sub.2 is a hydrogen atom or a methyl group, and when R.sub.2 is a methyl group R.sub.3 is also a methyl group, and when R.sub.2 is a hydrogen atom R.sub.3 is a group of the formula, ##STR3## (wherein R.sub.5 is a halogen atom or a C.sub.1 -C.sub.3 alkyl, vinyl or a C.sub.1 -C.sub.3 alkoxymethyl group, R.sub.6 is a hydrogen or halogen atom or a methyl group, or, taken together, R.sub.5 and R.sub.6 may form a tetramethylene group by connecting together at ends thereof), R.sub.4 is a halogen atom or a C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxyl or 3,4-methylenedioxy group, n is 1 or 2 and Y is a isopropyl or cyclopropyl group. These carboxylic acid esters are useful as insecticides and acaricides.
