Three monoenyl compounds were detected in GC/MS analysis of a hexane extract of pheromone glands from virgin female Acrolepiopsis sapporensis. They were identified as (Z)-11-hexadecenyl acetate (Z11-16:Ac), (Z)-11-hexadecenal (Z11-16:Ald) and (Z)-11-hexadecenol (Z11-16:OH), respectively, by chemical derivatization and synthesis of both geometric isomers. The ratio of three components in the sex pheromone gland of female moths was 100:10:23 with GC/MS analyses. In field tests, blends of the three components were evidenced to attract male moths in a Welsh onion field. Synthetic (Z)-11-hexadecenal was the principal component to catch more males.
