| Abstract: | (Z,Z,Z)-1,3,6,9-Heneicosatetraene was identified as a sex pheromone component ofEpirrita 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 maleE. 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. |
