Bees of the Meliponini tribe are the most diverse group of social bees in the world and their need for trophic resources (pollen and nectar) makes them the main floral visitors and consequently the main pollinators of tropical forests. The trophic resources of stingless bees of the genera Melipona, Frieseomelitta and Plebeia (Apidae: Meliponini) were studied during the dry season of 2016 and rainy season of 2017 in the meliponary “Sucupira” located east of Manaus-AM (03°00’05” and S, 59°51’ 05 W). The most representative botanical families in this study, both in the dry and rainy seasons, were: Melastomataceae, Fabaceae, Anacardiaceae, and Arecaceae. The highest levels of diversity and uniformity of collected pollen types were observed for Friseomelitta sp. (H’=2.318; J’=0.712) in the rainy season, followed by F. varia (H = 2.044 and J’= 0.607) in the dry season. Even with their unique preferences, the bees presented a high degree of nestedness, both for presence and absence data (30.47; p < 0.001) and quantitative data (30.75; p= <0.001). Despite the richness of resources collected (87 pollen types), the results indicate that some botanical groups form the basis of these bees' diets, which justifies the trophic relations indicated by the high network nestedness.

Meliponini 部落的蜜蜂是世界上最多样化的群居蜜蜂，它们对营养资源（花粉和花蜜）的需求使它们成为主要的花卉访客，从而成为热带森林的主要传粉者。2016 年旱季和 2017 年雨季，在位于马瑙斯东部 (03°00'05) 的无刺蜜蜂“Sucupira”研究了 Melipona、Frieseomelitta 和 Plebeia 属（蜜蜂科：Meliponini）无刺蜂的营养资源。” 和 S，59°51' 05 W）。本研究中旱季和雨季最具代表性的植物科是：野牡丹科、豆科、漆树科和槟榔科。观察到收集的花粉类型的最高水平的多样性和均匀性弗里斯奥梅利塔sp。（H'=2.318；J'=0.712）在雨季，其次是F. varia（H=2.044 和 J'=0.607）在旱季。即使蜜蜂具有独特的偏好，但它们在存在和不存在数据（30.47；p < 0.001）和定量数据（30.75；p = <0.001）方面都表现出高度的嵌套性。尽管收集的资源很丰富（87 种花粉类型），但结果表明，一些植物类群构成了这些蜜蜂饮食的基础，这证明了高度网络嵌套所表明的营养关系是合理的。
