Abstract

The pollen host selection by 19 bee species, which have their main Central European distribution in the Alps, was assessed by microscopical analysis of the scopal contents of about 900 females from museum and private collections. The results of the pollen analyses were complemented by a literature survey as well as by field observations. The examined species widely vary in pollen host spectrum and specialization, revealing a fascinating diversity in bee host plant use. Observed patterns of host plant choice range from narrow specialists, which exclusively collect pollen from the flowers of a single plant genus, to pronounced generalists, which harvest pollen from the flowers of up to 17 different plant families. A quantitative character is given to separate the morphologically very similar females ofPanurginusherziandP.montanus.
Andrena属、Panurginus属、Dufourea属、Megachile属、Hoplitis属和Osmia属的主要高山蜜蜂对花粉寄主的选择
通过对博物馆和私人收藏的约900只雌性蜜蜂的花粉含量进行显微镜分析,评估了19种蜜蜂的花粉宿主选择,这些蜜蜂主要分布在阿尔卑斯山的中欧地区。花粉分析的结果得到了文献调查和实地观察的补充。所研究的物种在花粉寄主谱和特化方面差异很大,揭示了蜜蜂寄主植物用途的迷人多样性。观察到的寄主植物选择模式从狭义专家(专门从一个植物属的花中收集花粉)到明显的多面手(从多达17个不同植物科的花中采集花粉)不等。对形态上极为相似的斑蝥和山地蛙进行了定量鉴别。
