Volatiles were captured on Porapak Q from foreign grain beetles,Ahasverus advena (Waltl), feeding on rolled oats at various population densities. At low population density, males, females, and mixed-sex beetles four to six weeks posteclosion and older produced 1-octen-3-ol. Mixed-sex beetles emitted almost pure (R)-(-) enantiomer. Weekly production rates of 1-octen-3-ol by males were at least four times greater than those of females. Production of 1-octen-3-ol was barely detectable in volatiles from mixed-sex adults maintained at the highest population density. Laboratory bioassays in a two-choice, pitfall olfactometer modified to retain responding beetles revealed that 1-octen-3-ol serves as an aggregation pheromone forA. advena. Both racemic and chiral 1-octen-3-ols were good attractants for mixed-sex adults in the pitfall olfactometer.
从取食膨化燕麦的异国谷盗（Ahasverus advena（Waltl））中用 Porapak Q 捕获挥发物。在低种群密度下，雌雄两性和 4 至 6 周龄的混合性别的刚化蛹的甲虫会产生 1-辛烯-3-醇。混合性别的甲虫释放几乎纯的（R）-（-）对映体。雄性每周的 1-辛烯-3-醇的产生速率至少是雌性的四倍。在最高种群密度下饲养的混合性别的成虫挥发物中几乎检测不到 1-辛烯-3-醇的产生。在一个经改良以保留反应甲虫的双选择、陷阱嗅觉计的实验室生物测定中，发现 1-辛烯-3-醇是 A. advena 的聚集信息素。在陷阱嗅觉计中，外消旋和手性 1-辛烯-3-醇对混合性别的成虫都是很好的引诱剂。
