The current knowledge about pollinators in sub-Saharan Africa is extremely scarce. General pollinator distributions and resource usages are mainly unknown, as are the main pollinators of different crops (Timberlake and Morgan 2018). In early 2011, I travelled to an Afromontane area of Ethiopia, where arabica coffee, Coffea arabica L., has its origin, to survey coffee pollinators. I surveyed 19 coffee sites, most managed with organic practices, across a gradient from state-owned, shaded semi-plantation coffee to coffee grown sparsely, more or less wild, in the understory of disturbed natural forests (Fig 1a, b).

为什么阿拉比卡咖啡在其原生范围内被如此少的非蜜蜂访问？

目前关于撒哈拉以南非洲授粉媒介的知识极为匮乏。一般传粉媒介的分布和资源使用主要是未知的，不同作物的主要传粉媒介也是如此（Timberlake 和 Morgan 2018）。2011 年初，我前往埃塞俄比亚的 Afromontane 地区，调查咖啡授粉者，在那里，阿拉比卡咖啡 (Coffea arabica L.) 起源于阿拉比卡咖啡 (Coffea arabica L.)。我调查了 19 个咖啡场所，其中大多数采用有机做法进行管理，从国有的、遮荫的半种植园咖啡到在受干扰的天然森林的林下植被稀疏、或多或少是野生的咖啡（图 1a、b）。
