( Z,Z,Z )‐1, 3, 6, 9‐Heneicosatetraene was identified as a sex pheromone component of Epirrita autumnata (Borkhausen), (Lepidoptera: Geometridae). Gas chromatography coupled with electroantennographic detection revealed one active peak‐from female pheromone gland extracts. The chemical identification of the compound was based on gas chromatography‐mass spectrometry, chemical micro‐reactions and unambiguous synthesis. In a field test, a rubber septum loaded with 3000 μg of this compound showed highest attraction of male E. autumnata moths compared to lower doses and the control. The attraction of males to a 300 μg bait was equivalent to that obtained using live virgin females.
