title: Identification of the Female Sex Pheromone of the Leafroller Proeulia triquetra Obraztsov (Lepidoptera: Tortricidae).
abstract: Proeulia triquetra Obraztsov (Lepidoptera: Tortricidae) is an occasional pest in fruit orchards in central-southern Chile. In order to develop species-specific lures for detection and monitoring of this species, we identified the female-produced sex pheromone. (Z)-11-Tetradecenyl acetate (Z11-14:OAc), (E)-9-dodecenyl acetate (E9-12:OAc), and (E)-11-Tetradecenyl acetate (E11-14:OAc) were identified as biologically active compounds present in female pheromone glands by solvent extraction of the gland and analysis of the extracts by gas chromatography-electroantennographic detection and gas chromatography-mass spectrometry. In field tests, lures baited with synthetic Z11-14:OAc and E9-12:OAc in a 10:1 ratio were highly attractive to males of the species.
