Intermale variation in pheromone signaling has been confirmed and quantified by measurements of pheromone produced by single adult male Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae). Males varied in both the amounts of the two components of their aggregation pheromone and the ratio of one component to the other. The mean rates of production of the pheromone components T1 and T2 were 1.9 and 0.5 microg/day, respectively. There were repeatable differences among males in the amounts of T2 produced and the proportion of T1 in the pheromone blend over two weeks. Of the 15 males studied, one released a large burst of pheromone in a short period, while the remainder, if they did release, did so over an extended period. This suggested that there may be two alternative release strategies and the significance of this is discussed.
通过对成年雄性截尾材小蠹（Prostephanus truncatus (Horn)）（鞘翅目：长蠹科）个体产生的信息素进行测量，已证实并量化了雄性间信息素信号的差异。雄性聚集信息素的两种成分的含量以及一种成分与另一种成分的比例各不相同。信息素成分T1和T2的平均产生速率分别为1.9微克/天和0.5微克/天。在两周时间内，雄性之间在T2的产生量以及信息素混合物中T1的比例方面存在可重复的差异。在研究的15只雄性中，有一只在短时间内释放了大量信息素，而其余的雄性（如果释放的话）则是在较长时间内释放。这表明可能存在两种不同的释放策略，并对其意义进行了讨论。
