Abstract The first pollen study for the solitary bee Ancyloscelis apiformes (Emphorini) in a nest aggregation in the Central Amazon was made in October 2012 at the Sucupira apiary in east Manaus, Amazonas, at 03° 00ʹ 05″ S, 59° 51ʹ 05″ W. A total of 15 samples/nests (N1–N15) were analysed, including intact pollen loads (stored inside the nest) and post-emergence residues, which were acetolysed and mounted in glycerine gelatin. From each sample, 500 pollen grains were counted to determine the pollen frequencies and diversity (H′) and evenness (J′) indices. The most representative pollen types were Bonamia ferruginea (N1 = 95.6% and N2 = 96.00%) and the Ipomoea (N3 = 96.40%), both of which belong to the Convolvulaceae. In addition, Byrsonima crispa (N10 = 93.40%) and Malpighia glabra (N7 = 90.20% and N9 = 97.60%), representatives of the Malpighiaceae, were classified as temporary specialisation events with frequencies above 90%. In this study, A. apiformes, which is considered an oligolectic bee species, presented a polylectic tendency since it collected large percentages of pollen types from plants in distinct families that were not phylogenetically related.

Ancyloscelis apiformes (Apidae: Emphorini) 在亚马逊中部的第一个花粉记录

摘要 2012 年 10 月,在亚马孙马瑙斯东部的 Sucupira 养蜂场,在南纬 03° 00ʹ 05″、59° 51ʹ 05″,对亚马逊中部巢群中的独居蜂 Ancyloscelis apiformes (Emphorini) 进行了第一次花粉研究。 W. 总共分析了 15 个样本/巢(N1-N15),包括完整的花粉负荷(储存在巢内)和出苗后残留物,它们被乙酰化并固定在甘油明胶中。从每个样品中,计数 500 个花粉粒以确定花粉频率和多样性 (H') 和均匀度 (J') 指数。最具代表性的花粉类型是Bonamia ferruginea (N1 = 95.6% and N2 = 96.00%) 和Ipomoea (N3 = 96.40%),两者都属于旋花科。此外,Byrsonima creama (N10 = 93.40%) 和 Malpighia glabra (N7 = 90.20% 和 N9 = 97.60%),Malpighiaceae 的代表,被归类为频率超过 90% 的临时特化事件。在这项研究中,被认为是寡聚蜂种的 A. apiformes 呈现出多聚趋势,因为它从不同科的植物中收集了大量的花粉类型,这些植物在系统发育上没有关系。
