雄木犀草（Tribolium castaneum）产生一种聚集信息素，吸引同种的雌木犀草。我们使用双选择陷阱测试了4个实验种群的雌性对从每个种群的雄性收集的天然信息素和合成4,8 -二甲基癸醛的反应。三个种群来自7年前收集的动物：两个在西班牙，一个在南斯拉夫。第四个种群已经在芝加哥的实验室培养了至少30年。在两种种群选择测试的8种组合中，雌性对来自自己种群和来自另一个种群的信息素没有区别；在剩下的四种组合中，有三种雌性对来自自己种群的刺激有明显的歧视。来自实验室种群和一个西班牙种群的雌性对不同浓度的合成4,8 -二甲基癸醛没有不同的反应。来自其他西班牙人口的女性对浓度的反应随着浓度的增加而增加，而来自南斯拉夫人口的女性对中间浓度的反应最大。我们讨论了这些结果的可能的化学基础，以及它们的进化意义。
Male Tribolium castaneum (Herbst) produce an aggregation pheromone that attracts conspecific females. We used a two-choice pitfall trap to test the response of females from four laboratory populations to natural pheromone gathered from males of each population and to synthetic 4, 8-dimethyldecanal. Three populations were derived from animals collected 7 years ago: two in Spain and one in Yugoslavia. The fourth population had been in laboratory culture at Chicago for at least 30 years. In eight combinations of the two population choice tests, females did not discriminate between pheromone from their own population and from another population; in three of the four remaining combinations, females discriminated significantly against the stimulus from their own population. Females from the laboratory population and one Spanish population did not respond differently to different concentrations of synthetic 4, 8-dimethyldecanal. Females from the other Spanish population showed an increasing response with increasing concentration, and females from the Yugoslavian population responded most to an intermediate concentration. We discuss the possible chemical bases for these results, and their evolutionary implications.
