雄性兰花蜂制造香水是一种独特的行为,在新热带地区引起了整个授粉综合征。1,2雄性兰花蜂利用从多种环境来源(包括兰花)获得的挥发物,在专门的后腿口袋中调制和储存物种特异性香水混合物。4,5然而,这种行为的功能和最终原因仍然不清楚。2,6虽然以前的观察表明,男性香水作为化学信号,女性的吸引力还没有显示。7,8在这里,我们证明,拥有香水增加男性交配成功率和父权在Euglossa困境,一种兰花蜜蜂最近在佛罗里达归化。我们补充男性饲养的陷阱巢与香水负荷收获野生同种。在双重选择实验中,补充了香水的雄性与更多的雌性交配,并产生更多的后代,而不是未经处理的同龄对照雄性。虽然香水的补充对雄性求爱的强度影响不大,但它改变了雄性之间的互动。我们的研究结果表明,男性获得的香水是刺激女性交配的性信号,并表明性选择是塑造兰花蜜蜂香水通信进化的关键。
Perfume making in male orchid bees is a unique behavior that has given rise to an entire pollination syndrome in the neotropics.1,2Male orchid bees concoct and store species-specific perfume mixtures in specialized hind-leg pockets3using volatiles acquired from multiple environmental sources, including orchid flowers.4,5However, the function and the ultimate causes of this behavior have remained elusive.2,6Although previous observations suggested that male perfumes serve as chemical signals, the attractiveness for females has not be shown.7,8Here, we demonstrate that the possession of perfume increases male mating success and paternity inEuglossa dilemma, a species of orchid bees recently naturalized in Florida. We supplemented males reared from trap-nests with perfume loads harvested from wild conspecifics. In dual-choice experiments, males supplemented with perfumes mated with more females, and sired more offspring, than untreated, equal-aged, control males. Although perfume supplementation had little effect on the intensity of male courtship display, it changed the dynamics of male-male interactions. Our results demonstrate that male-acquired perfumes are sexual signals that stimulate females for mating and suggest that sexual selection is key in shaping the evolution of perfume communication in orchid bees.
