Abstract:
[Objectives]  To identify the active components of the sex pheromone of female Zeuzera leuconotum Butler moths. [Methods]  Sex pheromones were extracted from the sex glands of female moths with n-hexane and the active components analyzed using gas chromatography (GC) and gas chromatography–mass spectrometry (GC-MS). Electroantennograms (EAG) were used to examine the EAG responses of male antennae to extracts and standard components. [Results]  GC results indicate that there are 7 chemicals in the extract, and that the peak height and area of component G increased after the addition of standard compound E2,Z13-18:Ac. Based on GC-MS data, component G was identified as E2,Z13-18:Ac. The EAG results show that all compounds caused an antennal reaction, and that E2,Z13-18:Ac elicited the strongest EAG activity. [Conclusion]  E2,Z13-18:Ac was identified as the main component of the sex pheromone of Z. leuconotum. These results provide a theoretical basis for developing synthetic sex pheromone lures to control this pest.
