Stingless social bees have been used in the Meliponiculture as a sustainable activity by several indigenous communities in Central Amazon. Pollen samples collected by  Melipona dubia ,  Melipona seminigra  and  Scaptotrigona  sp. bees from communities of the Sateré Mawé tribe were analyzed and 61 pollen types were identified. The most representative botanical families in the samples were: Anacardiaceae, Arecaceae, Burseraceae, Euphorbiaceae, Dilleniaceae, Fabaceae, Melastomataceae, and Myrtaceae. Among these families, the most representative was pollen of  Miconia  type (Melastomataceae) collected by bees  Melipona dubia  and  Melipona seminigra . Also, pollen of  Croton cajucara  (Euphorbiaceae) and  Eugenia  type (Myrtaceae) collected by bee  Scaptotrigona  sp., these species of bees presented temporary specialization (&gt;90%) in some samples. On the other hand,  Scaptotrigona  sp.showed higher richness in their collections (H' =1.66 and J’= 0.45), followed by  Melipona seminigra  (H' = 1.43 and J’= 0.39) and  Melipona dubia  with (H' = 0.45 and J’= 0.14). The connectance of interactions between bees and plants in the study locations was 19.37%, which is considered high for palynological data. The other network metrics, both for presence and absence (NODF= 54.07) and for quantitative matrix (WNODF = 34.03) were found to be significant (p &lt; 0.001) and highly nested. Cluster analysis from the collected resources presented two distinct groups, a group formed by the genus  Melipona  and another by  Scaptotrigona .The results show that even though they have their peculiarities in the collections, these groups of bees share many resources, presenting themselves as both generalists and temporary specialists, according to the colony’s needs.
