| Abstract: | Dodecyl acetate (12:OAc) ( E )-10-dodecenyl acetate ( E 10-12:OAc) and ( E )-10-dodecenol ( E 10-12:OH) in the ratio 8 : 80 : 12 were collected by solid phase micro-extraction of the volatiles emitted by virgin signalling females of the spotted tentiform leafminer moth, Phyllonorycter blancardella . The same compounds in the ratio 8 : 79 : 13 were extracted from the sex pheromone glands of virgin signalling females of the same species. The chemical structures of the compounds were identified by gas chromatography and mass spectrometry. Trapping results obtained from field tests using synthetic components of the sex pheromone demonstrated that only one component, E 10–12:OAc, was essential for the attraction of conspecific males and should be considered as a sex pheromone. |
