由于多个foundresses和/或工人漂移具有可变的群体内相关性的真社会性汗蜂可能在非巢友中表达高水平的耐受性。我们使用圆管竞技场来测试与这种现象相关的假设，在Halictus scabiosae（罗西），一个专性的真社会性物种，频繁的巢间工人漂移。我们在7月中旬进行了实验，蜜蜂来自土耳其共和国布尔萨市附近的UludaExpense大学校园内的一个蜂巢。我们记录了高频率的容忍行为，在巢和非巢试验。在容忍行为中，相互传递行为在有巢对中更为常见，而非攻击性接触行为在无巢对中更为常见。中等水平的侵略是频繁的，特别是在nestmate试验，和避免是更常见的非nestmate对。除了中等水平的侵略，我们的研究结果是相似的Lasioglossum malachurum Kirby，另一个专性真社会物种具有较强的耐受性同种和巢，往往包括相关和不相关的工人的混合物。因此，我们的观察结果支持这一假设，即减少群体内的相关性，导致多个foundresses和/或真社会性汗蜂的同种群体之间的漂移，是与高水平的耐巢。
Eusocial sweat bees with variable intra-colony relatedness due to multiple foundresses and/or worker drifting may express high levels of tolerance among non-nestmates. We used circle-tube arenas to test hypotheses related to this phenomenon in Halictus scabiosae (Rossi), an obligately eusocial species with frequent inter-nest worker drifting. We conducted experiments in mid-July with bees from a nest aggregation found on the Uludağ University campus, near the city of Bursa, in the Republic of Turkey. We recorded high frequencies of tolerant behaviors in both nestmate and non-nestmate trials. Among tolerant behaviors, mutual passing was more common in pairs of nestmates while non-aggressive contacts were more common in non-nestmate pairs. Moderate levels of aggression were frequent, particularly in nestmate trials, and avoidance was more common in non-nestmate pairs. Except for the moderate levels of aggression, our results are similar to those on Lasioglossum malachurum Kirby, another obligately eusocial species with strong tolerance for conspecifics and with nests that often include a mixture of related and unrelated workers. Thus, our observations support the hypothesis that reduced intra-colony relatedness, resulting from multiple foundresses and/or drifting among conspecific colonies of eusocial sweat bees, is correlated with high levels of tolerance among nestmates.
