Abstract

Herein disclosed are novel imidazolidine derivatives of the formula (I) and intermediates of the formula (II) ##STR1## wherein each R represents a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, a halogen atom, an alkoxy group having from 1 to 6 carbon atoms, a methylenedioxy group, an alkylthio group having from 1 to 4 carbon atoms, a haloalkyl group having from 1 to 2 carbon atoms, a haloalkoxy group having from 1 to 4 carbon atoms, an alkylcarbonyl group having from 1 to 6 carbon atoms, an alkoxycarbonyl.group having from 1 to 6 carbon atoms, a hydroxy group, a cyano group, a nitro group, an alkylamino group having from 1 to 8 carbon atoms, a phenyl group, a phenoxy group, a benzyl group or a halopyridylmethyloxy group, and n is an integer of from 1 to 3, ##STR2## wherein R and n have, respectively, the same meanings as defined above. Processes for preparing the compounds of the formulas (I) and (II) are also described. Moreover, insecticidal compositions comprising an effective amount of the derivative (I) are described.
