研究了日本兵库县科比的一种原生兰花盘龙参的传粉生物学。australis花经常被管理的蜜蜂A.意利费拉。由于蜜蜂从花药中提取花粉并将花粉沉积在许多花的柱头上，这种行为导致即使在一次访问中也能成功地为多朵花授粉。鉴于（i）蜜蜂是我们观察期间最频繁和最密集的传粉者，（ii）调查种群的坐果率显著高于先前调查的S。australis种群，尽管缺乏自主自花授粉能力，但A.意利花可能促进S.澳大利亚。我们的观察提供了一些深入了解蜜蜂传粉相互作用的多样性，提请注意非本地蜜蜂作为传粉者的潜在重要性。
We studied the pollination biology of a native orchid Spiranthes australis in Kobe, Hyogo, Japan, and observed that S. australis flowers are frequently visited by the managed honeybee A. mellifera. Since the honeybees extracted pollinaria from the anthers and deposited pollinia on the stigmas of many flowers, the behavior resulted in the successful pollination of multiple flowers even in a single visitation. Given that (i) the honeybee was the most frequent and intensive pollinator during our observation period and (ii) the fruit set in the investigated population was significantly higher than the fruit set of a previously investigated S. australis population, despite lack of ability for autonomous self-pollination, A. mellifera may promote a high reproductive success in S. australis. Our observation provides some insight into the diversity of orchid-pollinator interactions, drawing attention to the potential importance of non-native bees as pollinators.
