为了避免与近亲交配，进化出了一系列的交配隔离机制。在群居昆虫（蜜蜂、黄蜂和蚂蚁）中常见的交配聚集中，来自同一群体的有性个体可能存在，因此某种类型的群体识别系统将有助于避免近亲繁殖。在蚂蚁Formica exsecta中，工蚁使用群体特异性（Z）9-烯烃谱来区分巢友和非巢友，因此该信息具有用于交配行为的潜力，即识别潜在的配偶，避免近亲繁殖和指示交配状态。然而，在F. exsecta皇后，我们没有发现一致的定量或定性差异，角质碳氢化合物（CHC）配置文件之间的男性和皇后，或任何变化与交配皇后。（Z）9-烯烃识别谱似乎也不起交配前屏障的作用，因为成功交配发生在广泛的CHC谱中。F. exsecta似乎是雄性随后是女王的连续生产加上长的交配期，这是许多社会性昆虫采取的策略。
A wide range of mating isolating mechanisms has evolved to avoid mating with close relatives. In mating aggregations that commonly occur in social insects (bees, wasps and ants) sexuals from the same colony can potentially be present, so some type of colony-recognition system would be useful to avoid inbreeding. In the ant Formica exsecta, colony-specific (Z)9-alkene profiles are used by workers to distinguish nest-mates from non-nest-mates, so this information has the potential to be employed in mating behaviour, i.e. to recognise potential mates, avoid inbreeding and indicate mating status. However, in F. exsecta queens, we found no consistent quantitative or qualitative differences in the cuticular hydrocarbon (CHC) profiles between males and queens, or any changes associated with mating in queens. Neither did the (Z)9-alkene recognition profile appear to be acting as a pre-mating barrier, since successful mating occurred across a wide range of CHC profiles. The main pre-mating barrier in F. exsecta appears to be the sequential production of males followed by queens coupled with a long mating period, a strategy adopted by many social insects.
