The paper aims to further determine active ingredients of the sex pheromone and chemical structures thereof of Apocheima cinerarius by screening the analogues of A. cinerarius , which is signifi cant for the future elicitation experiments and is helpful for non-pollution control of diseases and insect pests. [Methods] According to the previous research, the active ingredients of the sex pheromone of A. cinerarius have been proved to be tetradecenyl acetate. By synthesizing a serious of tetradecenyl acetates and using GC-EAD method, the position of double bond and confi guration were determined. [Results] The GC-EAD spectrogram indicated that sensitive reaction of male moth antenna was detected to Z4-14∶OAc and Z6-14∶OAc. [Conclusions] Z4-14∶OAc and Z6-14∶OAc are the active ingredients of the sex pheromone of A. cinerarius .
