[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 configuration 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.
