化学识别线索用于区分物种、同种，甚至可能区分社会性昆虫群体中的父系。尽管有证据表明群居昆虫通过“格式塔”机制混合群体气味，但关于父系线索是否可能持续存在的争论仍在继续，因为父系识别可能导致裙带关系。我们分析了来自 76 个蚁群的 688 只福米卡蚂蚁中不同交配频率或蚁后数量的识别线索（表皮碳氢化合物）的变化。我们发现随着遗传多样性的增加，概况方差没有增加，这表明父系效应不存在或可能被格式塔机制掩盖。然后我们证明，一个孤立个体的特征相对于其群体特征发生了相当大的变化，并在 5 天后稳定下来。我们利用这些孤立的个体来消除格式塔机制的掩蔽效应，并且我们在孤立的成年工人和新出现的幼年工人中发现了微弱但统计上显着的父系效应。因此，我们的证据表明，F. exsecta 蚂蚁的表皮碳氢化合物谱（正构烷烃和烯烃）的遗传变异导致了父系之间的差异，但它们在群体环境中被掩盖，从而避免了代价高昂的裙带关系行为。
Chemical recognition cues are used to discriminate among species, con-specifics, and potentially between patrilines in social insect colonies. There is an ongoing debate about the possible persistence of patriline cues despite evidence for the mixing of colony odors via a “gestalt” mechanism in social insects, because patriline recognition could lead to nepotism. We analyzed the variation in recognition cues (cuticular hydrocarbons) with different mating frequencies or queen numbers in 688 Formica exsecta ants from 76 colonies. We found no increase in the profile variance as genetic diversity increased, indicating that patriline effects were absent or possibly obscured by a gestalt mechanism. We then demonstrated that an isolated individual's profile changed considerably relative to their colony profile, before stabilizing after 5 days. We used these isolated individuals to eliminate the masking effects of the gestalt mechanism, and we detected a weak but statistically significant patriline effect in isolated adult workers and also in newly emerged callow workers. Thus, our evidence suggests that genetic variation in the cuticular hydrocarbon profile of F. exsecta ants (n-alkanes and alkenes) resulted in differences among patrilines, but they were obscured in the colony environment, thereby avoiding costly nepotistic behaviors.
