Four compounds, (z)-9-tetradecenyl acetate (Z9-14 : Ac), (Z, E)-9, 12-tetradecadienyl acetate (Z9, E12-14: Ac), (Z)-9-tetradecen-1-ol (Z9-14: OH) and (Z, E)-9, 12-tetradecadien-1-ol (Z9, E12-14: OH) were found in sex pheromone extracts of female Spodoptera exigua from Japan. The ratio of these compounds was 60:98:100:83, respectively. Electroantennogram analysis of male moths to these four compounds suggests that receptor cells for these compounds are present in their antenna. Single sensillum recordings from male-specific trichodea (type-1 trichodea) showed that the sensitivity of type-B cells (Z9-14 : OH receptor cells) to Z9, E12-14: OH was not significantly different from the sensitivity to Z9-14: OH, whereas the threshold of type-A cells (Z9, E12-14: Ac receptor cells) to Z9-14: Ac was 1, 000 times higher than the sensitivity to Z9, E12-14: Ac. Z9, E12-14: OH was suggested to have some activity as a sex pheromone component in the Japanese population of S. exigua.
