摘要

A insecticide comprises a hydrazone derivative (I). An insecticide comprises a hydrazone derivative of formula (I). [Image] A, Q : aryl or heteroaryl (both optionally substituted); W : O, aminilene (optionally substituted), alkylene, oxyalkylene or alkyleneoxy; X 1, X 2H, CHO, Alk (optionally substituted), Alk 1, Ar, Het, acyl, COOAlk, COOAr, COOHet, SAlk, SAr, SHet, SO 2Alk, SO 2Ar or SO 2Het; Alk : alkyl; Alk 1alkenyl or alkynyl; Ar : aryl; Het : heterocyclyl; Y : O or S; and Z' : H, halo, CN, alkyl (optionally substituted), alkenyl, alkynyl, amino, alkoxy or alkylthio. An independent claim is also included for a compound of formula (II).
