The primitively social sweat bee, Lasioglossum zephyrum, blocks the entry into its nest of most conspecifics from other colonies. Laboratory inbreeding of these bees produced lines which showed a positive linear relationship between the coefficient of relationship of bees tested and how often they permitted non-nestmates to pass them. The most probable mechanism is a genetically determined odor coupled with a learned component by which guard bees discriminate between odors of close kin and other bees.
原始社会性的熊蜂，Lasioglossum zephyrum，会阻止大多数来自其他群体的同种个体进入其巢穴。对这些蜜蜂进行实验室近亲繁殖产生的品系表明，被测试蜜蜂的亲缘系数与它们允许非巢伴通过的频率之间呈正线性关系。最可能的机制是一种由遗传决定的气味，加上一种由守卫蜜蜂识别近亲气味和其他蜜蜂气味的学习成分。
