The sex pheromone of Synanthedon bicingulata (Staudinger), a major pest of Prunus species in many regions of northeast Asia, was identified. Two major components from the pheromone gland extracts of female moths are ( E , Z )-3,13-octadecadienyl acetate ( E 3, Z 13-18:OAc) and ( Z , Z )-3,13-octadecadienyl acetate ( Z 3, Z 13-18:OAc), and the average ratio of these components is about 4:6, respectively. In addition to the major components, four minor components, ( Z )-13-octadecenyl acetate ( Z 13-18:OAc), ( E , Z )-2,13-octadecadienyl acetate ( E 2, Z 13-18:OAc), ( E , Z )-3,13-octadecadien-1-ol ( E 3, Z 13-18:OH), and ( Z , Z )-3,13-octadecadien-1-ol ( Z 3, Z 13-18:OH) also were identified from pheromone gland extracts. Field tests showed that E 3, Z 13-18:OAc and Z 3, Z 13-18:OAc are essential for attraction of male S. bicingulata moths, and males are optimally attracted to the blend ratio found in pheromone gland extracts of conspecific females. Addition of the minor glandular components ( Z 13-18:OAc, E 2, Z 13-18:OAc, E 3, Z 13-18:OH, and Z 3, Z 13-18:OH) did not affect captures of males to the primary binary blend. Thus, the blend of E 3, Z 13-18:OAc and Z 3, Z 13-18:OAc at the natural ratio can be used for monitoring populations of this species.
