Large expanses of the big country of Peru remain still unexplored. Studies on the pollination biology of perfume orchids and their pollinators, perfume gathering male euglossine bees, would be carried out in the following areas: the Machu Picchu reserve, the surroundings of Iquitos, and at Panguana field station. Perfume gathering bees are easy to attract and trap with chemical baits. Baiting experiments with new, untested substances, found in the fragrance composition of orchids cultivated in the Botanical Garden Munich will throw some light on the specificity of the respective male euglossine bees. From the hymenoptera carrying orchid pollinaria it is possible to study orchid pollination and distribution without any orchids. Thus, indirectly the presence of the orchid species hidden in the jungle or growing in unreachable heights will be confirmed alone by the pollinaria attached to the bee. The goal of the expedition is to fill gaps in the floristic data of Peru and to enhance the knowledge concerning Peru’s orchid flora and the role of its pollinators. Finally a floristic assessment of the field station Panguana would be initiated. The flora of this area remains still unexplored. Over a period of 3 weeks a first step in the botanical investigation of the station would be achieved.

幅员辽阔的秘鲁仍未得到开发。将在马丘比丘保护区、伊基托斯周围地区和潘瓜纳野外站对香兰花及其传粉者香水采集雄蜂的授粉生物学进行研究。采集香水的蜜蜂很容易被化学诱饵引诱和诱捕。在慕尼黑植物园种植的兰花的香味成分中发现了新的、未经测试的物质，用这些物质进行诱饵实验将有助于揭示各自雄性优黄蜂的专一性。从膜翅目携带兰花的花粉中可以研究兰花的授粉和分布，而不需要任何兰花。因此，隐藏在丛林中或生长在遥不可及的高处的兰花物种的存在，将由附着在蜜蜂身上的花粉单独证实。考察的目的是填补秘鲁植物区系数据的空白，并加强对秘鲁兰科植物区系及其传粉者作用的了解。最后，将开始对Panguana外地站进行植物区系评估。这一地区的植物区系仍未开发。在为期3周的时间里，将完成对该站的植物学调查的第一步。
