This study aimed to evaluate the influence of biome, host species, and microhabitat on the community structure of yeasts (using culture-dependent methods) and fungi (culture-independent methods) in bees and to identify the functional characteristics of isolated strains. Samples were collected from the body, hive, honey, and beebread of bees from the genera <i>Trigona</i>, <i>Scaptotrigona</i>, <i>Tetragona</i>, <i>Apis</i>, <i>Meliponas</i>, and <i>Tetragonisca</i> in the Pantanal, Amazon, and Cerrado biomes. We isolated 176 strains representing 46 yeast species, predominantly from the genera <i>Starmerella</i> (44.32%), <i>Hanseniaspora</i> (5.16%), and <i>Wickerhamiella</i> (4.38%). <i>Starmerella etchellsii</i> (32%) was the most abundant species, while <i>Aureobasidium leucospermi</i> (&lt; 0.01%) was the least abundant. Only <i>S. etchellsii</i> and <i>S. apicola</i> (11%) were present in all bee species. The composition and abundance of yeasts were significantly influenced by biome and host species (PERMANOVA, <i>p</i> &lt; 0.05). Alpha diversity varied significantly among microhabitats (Dunn’s <i>p</i> &lt; 0.05), bee species, and biomes (Duncan <i>p</i> &lt; 0.05). Culture-independent methods identified 234 Ascomycota ASVs, 18 Basidiomycota ASVs, and 1 Mucoromycete ASV across 90 genera and 108 species. Saccharomycetales accounted for approximately 72% of the fungal abundance, with <i>S. apicola</i> (14.64%) and <i>S. meliponinorum</i> (11.21%) being the most abundant. Additionally, barcoding identified 100 ASVs of plants associated with bees, grouped into 22 families and 24 species, predominantly Asteraceae, Anacardiacea, Elaeocarpaceae, and Solanaceae.

Bacterial and fungal diversity were not significantly different across bee development. However, the composition of bacteria and fungi significantly changed between larval and fully pigmented adult stages, in agreement with dramatic changes in host morphology during metamorphosis. Many of the microbial taxa found in provisions were also present in larvae, indicating that immature bees likely acquire their microbiome from food. Notably, the most prevalent bacterial genus was <i>Arsenophonus</i>, a symbiont with many recorded phenotypes, ranging from reproductive parasitism to beneficial endosymbiont. <i>Arsenophonus</i> was found in samples from provisions and eggs, yet reached higher read counts in larvae and fully pigmented adults. The <i>Arsenophonus</i> amplicon sequencing variants (ASVs) detected in this study had high sequence similarity with a symbiont that displays the son-killing phenotype, suggesting that the ASVs in <i>O. lignaria</i> are also reproductive parasites. The causative agent of chalkbrood disease in bees, <i>Ascosphaera</i>, was also detected in provisions and larvae. Most other taxa present were plant pathogens or commonly found in soil.
