(Z,Z)-1,3,6-cis-9,10-Epoxyheneicosatriene

(Z,Z)-1,3,6-cis-9,10-Epoxyheneicosatriene is a key sex pheromone component isolated from the gland extracts of female fall webworm moths (Hyphantria cunea) and other Arctiidae species. It is typically combined with aldehyde compounds like (Z,Z)-9,12-octadecadienal and (Z,Z,Z)-9,12,15-octadecatrienal in specific ratios (e.g., 2:33.6:58.4:6) to form multi-component lures for monitoring and controlling this cosmopolitan quarantine pest. When loaded onto gray rubber septa at 200-300 μg doses, these blends can trap dozens of male moths per trap per day in cotton fields or urban green spaces, achieving over 50% higher monitoring accuracy than conventional light traps while remaining harmless to natural enemies and environmentally friendly.
