Glossosphecia romanovi (Leech) (Lepidoptera: Sesiidae) is a pest of grape in northeast Asia. We analyzed pheromone gland extracts of female moths and compared attractiveness of various pheromone blends to male moths in the field. Two major components from pheromone gland extracts were identified as ( Z , Z )‐3,13‐octadecadien‐1‐ol ( Z 3, Z 13‐18:OH) and ( Z , Z )‐3,13‐octadecadienyl acetate ( Z 3, Z 13‐18:OAc) in a ratio of approximately 9:1. Field tests showed that male G. romanovi were attracted to Z 3, Z 13‐18:OH alone, but the maximum number of males was attracted to the binary blend of Z 3, Z 13‐18:OH and Z 3, Z 13‐18:OAc mimicking the blend found in female extracts. In addition to these components, small amounts of ( E , Z )‐3,13‐octadecadien‐1‐ol ( E 3, Z 13‐18:OH) were detected in the pheromone gland of females, but addition of this component inhibited attraction to the primary binary blend. The blend of Z 3, Z 13‐18:OH and Z 3, Z 13‐18:OAc at the natural ratio should provide a sensitive and effective lure for monitoring populations of this pest.
