Abstract
From an extract of female abdominal tips of Leucania separata (Z)-11-hexadecenol and its acetate have been isolated as the two major components of the sex pheromone. Ratio of the acetate to the alcohol in the extract was found to be 8:1. Laboratory bioassay of the synthetic compounds in ratios of between 9:1 and 1:1 showed high pheromonal activity. Two major components of the sex pheromone of Leucania loreyi have been isolated from an extract of female abdominal tips. These were identified as (Z)-9-tetradecenyl acetate and (Z)-11-hexadecenyl acetate.
