(3Z,13Z)-3,13-Octadecadien-1-ol is a key sex pheromone component identified from the gland extracts of female Paranthrene regalis moths (vine tree borer)3. Through gas chromatography-mass spectrometry (GC-MS) and field bioassays, this compound was proven to specifically attract male moths by eliciting strong electrophysiological responses in their antennal neurons3. In practical pest management, it serves as a core bait in traps for monitoring and mass trapping male moths, disrupting mating and reducing larval infestations in vineyards.
