Abstract
Substituted pyridine methyl esters of cyclopropane carboxylic acids and the geometric and optical isomers thereof are prepared which correspond to the formula: ##STR1## wherein X independently represents alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, alkylthio of 1 to 4 carbon atoms, alkylsulfonyl of 1 to 4 carbon atoms, trifluoromethyl, 3,4-methylenedioxy, chloro, fluoro or bromo; n represents an integer of 0 to 2; Y represents oxygen or sulfur; R represents hydrogen, cyano or ethynyl and Z represents chloro, fluoro or bromo. These compounds have been found to exhibit a high degree of insecticidal activity and compositions containing said compounds are so employed.
