Abstract When electroantennographic responses of maleYponomeuta malinellus Zeller to model compounds were determined at dosages of 0.3–30 ng, the strongest responses were obtained from (Z)-9-dodecen-1-ol acetate (Z9–12∶Ac). Also, strong responses were obtained from (Z)-11-tetradecenal (Z11–14∶A1) and (Z)-11-tetradecen-1-ol (Zl1–14∶OH). At a dosage of 0.3 ng,Z11–14∶A1 produced a stronger response thanZ11–14∶OH, while at a dosage of 30 ng,Z11–14∶OH andZ11–14∶A1 produced equal responses. Gas chromatographic and mass spectral analysis of extracts of female sex pheromone glands showed the presence ofZ9–12∶Ac, tetradecan-1-ol (14∶OH), (E)-11-tetradecen-1-ol (E11–14∶OH),Z11–14∶OH, hexadecan-1-ol, and hexadecan-1-ol acetate in a ratio of 0.6∶200∶37∶100∶140∶35. In field tests,Z9–12∶Ac andZ11–14∶OH together were required for trap catch, and addition ofZ11–14∶A1,E11–14∶OH, 14∶OH, or (Z)-11-tetradecen-1-ol acetate did not increase catch. Ratios in rubber septa of 0.5∶99.5 to 1.5∶98.5 (Z9–12∶ Ac/Z11–14∶OH) captured the most males and captures were statistically equivalent for dosages of 10–1000 μg/rubber septum. Traps baited with the synthetic lure produced better catches than those baited with females.
