After males of Lasioglossum zephyrum (Hymenoptera: Halictidae) have first been exposed to a conspecific female, the attractiveness of a second female diminishes with increasing genealogical relationship between the two females. The most parsimonious explanation for this is a polygenically controlled female sex pheromone. Nonrandom mating preferences may markedly affect gene flow within and between natural populations. Polygenically controlled sex pheromones probably also enhance kin recognition among females and, thus, influence the evolution of eusocial behavior in bees and wasps.
当蓝带蜜蜂（膜翅目：叶蜂科）的雄性首次接触同种的雌性后，第二只雌性的吸引力会随着两只雌性之间亲缘关系的增加而降低。对于这种现象，最简约的解释是多基因控制的雌性性信息素。非随机交配偏好可能会显著影响自然种群内部和种群之间的基因流动。多基因控制的性信息素可能还会增强雌性之间的亲缘识别，从而影响蜜蜂和黄蜂的社会性行为的进化。
