Novel heterocyclic compounds of the formulawherein, Rrepresents a hydrogen atom or an alkyl group, A represents an ethylene group which may be substituted by alkyl or a trimethylene group which may be substituted by alkyl, X represents an oxygen or sulfur atom or the groupin which Rrepresents a hydrogen atom of an optionally substituted alkyl, an alkenyl, an alkynyl or an acyl group, and Rrepresents a hydrogen atom or an alkyl group, and Z represents an optionally substituted 5- or 6-membered heterocyclic group which contains at least two hetero atoms selected from oxygen, sulfur and nitrogen atoms, or an optionally substituted 3- or 4-pyridyl group. The above defined novel heterocyclic compounds of formula (I) exhibit powerful insecticidal properties.
