雄性 Nauphoeta cinerea 蟑螂之间的相互作用的特点是精心设计的仪式，导致两个个体之间形成稳定的主导-从属等级制度。涉及挥发性性信息素和角质层碳氢化合物的化学信号在建立和维持优势状态方面发挥着重要作用。本研究的目的是识别通过强迫二元相遇而获得的两次和三次主导或从属个体的角质层碳氢化合物。采用固相微萃取（SPME）和有机溶剂萃取两种方法来分离角质层碳氢化合物。总共鉴定出了 23 个角质层碳氢化合物的峰。分析显示，根据提取方法和优势地位，三倍优势和从属个体的碳氢化合物剖面存在定量差异。优势个体的特点是单甲基烷烃 11- 和 13-MeC36、13- 和 15-MeC38、11-、13- 和 15-MeC35 的比例较高，而从属个体则具有较高比例的以下单甲基烷烃：7-、9- 和 11-MeC31、5-MeC31、3- 和8-MeC32 和 9-、10-、11- 和 12-MeC32。讨论的重点是碳氢化合物作为优势状态指标的可靠性及其与生理过程的相关性。
Interactions between male Nauphoeta cinerea cockroaches are characterized by an elaborate ritual that leads to a stable dominant–subordinate hierarchy between two individuals. Chemical signals involving volatile sex pheromones and cuticular hydrocarbons play an important role in establishing and maintaining dominance status. The present study was performed to identify cuticular hydrocarbons in two- and three-times dominant or subordinate individuals obtained by forcing dyadic encounters. Two methods, i.e., solid-phase microextraction (SPME) and organic solvent extraction, were used to isolate cuticular hydrocarbons. A total of 23 peaks of cuticular hydrocarbons were identified. Analysis showed quantitative differences in hydrocarbon profiles of three-times dominant and subordinate individuals according to extraction method and dominance status. Dominant individuals were characterized by higher proportions of the monomethylalkanes 11- and 13-MeC36, 13- and 15-MeC38, and 11-, 13-, and 15-MeC35, while subordinate individuals had higher proportions of the following monomethylalkanes: 7-, 9-, and 11-MeC31, 5-MeC31, 3- and 8-MeC32, and 9-, 10- , 11-, and 12-MeC32. Discussion focuses on the reliability of hydrocarbons as indicators of dominance status and on their correlation with physiological processes.
