Using melissopalynology, we aimed to identify the plant species used by Frieseomelitta longipes (Smith, 1854) in the Tapajós–Arapiuns Extractive Reserve, a protected area in the Brazilian Amazon Basin. Honey samples were collected from F. longipes colonies in the Anã and Solimões communities for one year. The honey was acetolyzed and microscopically evaluated. Overall, we identified 184 pollen types distributed in 38 families, with 14 undetermined pollen types. Of this total, we found 104 exclusive pollen types in the Anã community honey, 58 exclusive pollen types in the Solimões community honey and 22 pollen types in honey from both areas. The most representative pollen types were: Caesalpinia peltophoroides, Cecropia, Delonix regia, Eugenia stipitata, Mimosa guilhardini, Psidium guajava, Spondias mombin, and Tapirira guianensis. The diversity (H') of pollen types was higher throughout the year in the Anã community, peaking in Feb/2017 (H' = 2.81), compared to Solimões honeys in Apr/2017 (H' = 2.61). The pollen spectrum of Anã samples revealed greater uniformity (J') for F. longipes, also peaking in Jan/2017 (J' = 0.97). On the other hand, we found the lowest J' values in the Solimões community samples, especially in Sep/2017 (J' = 0.76). In the Anã community, F. longipes expanded and diversified its collection of resources, revealing an extensive pollen niche and a more homogeneous collection pattern compared to the Solimões community.

利用蜂花粉质学，我们旨在识别巴西亚马逊盆地保护区 Tapajós-Arapiuns 采掘保护区中Frieseomelitta longipes （Smith，1854）使用的植物物种。蜂蜜样品是从Anã 和 Solimões 社区的F. longipes菌落采集的，为期一年。将蜂蜜乙酰分解并用显微镜进行评估。总体而言，我们鉴定了分布在 38 个科的 184 种花粉类型，其中 14 种花粉类型尚未确定。其中，我们在 Anã 群落蜂蜜中发现了 104 种独特的花粉类型，在 Solimões 群落蜂蜜中发现了 58 种独特的花粉类型，在这两个地区的蜂蜜中发现了 22 种花粉类型。最具代表性的花粉类型是：Caesalpinia peltophoroides、Cecropia、凤凰木、Eugenia stipitata、含羞草、番石榴、Spondias mombin和Tapirira guianensis。Anã 群落的花粉类型多样性 ( H ') 全年较高，与 2017 年 4 月的Solimões 蜂蜜 ( H ' = 2.61) 相比，在 2017 年 2 月达到顶峰 ( H ' = 2.81)。Anã 样品的花粉谱显示F具有更高的均匀性 ( J ') 。longipes，也在 2017 年 1 月达到顶峰 ( J ' = 0.97)。另一方面，我们发现最低的J' 索利莫斯社区样本中的值，特别是在 2017 年 9 月 ( J ' = 0.76)。在 Anã 群落中，F. longipes扩大了其资源收集范围并使其多样化，与 Solimões 群落相比，显示出广泛的花粉生态位和更均匀的收集模式。
