SUMMARY:

Bees pollinate wild and cultivated plants and the study of pollen grains can help to understand the food sources used by bees in forest areas, whether primary or secondary. In this study, the supply of pollen resources for stingless bees is evaluated in two areas of secondary forest in the municipality of Belterra, Baixo Amazonas, Pará, Brazil. The secondary forest sites are located in urban areas and are composed of meliponaries containing 230 bee boxes. Vegetation is being evaluated through the sampling of 10 plots of 10 x 15 m (150 m²), systematically distributed in each of the areas. From the analysis of the floristic composition, the Shannon diversity index (H'), the Pielou equability index and the Simpson dominance index will be calculated. For comparison between areas, cluster analysis will be performed, using an abundance matrix to calculate the similarity matrix with the Bray-Curtis index and the linkage method with the Unweighted Pair Group Method with arithmetic (UPMGA) algorithm. From the sampling of the flowering plants close to the meliponaries, a reference laminate is being made. The pollen material is being collected monthly in boxes of Melipona seminigra pernigra Moure & Kerr 1950 and Scaptotrigona xanthoricha Moure, 1950, submitted to acetolysis and mounted in glycerin gelatin. From the pollen samples, the parameters of network structure, diversity indices, evenness and niche overlap will be evaluated. The richness and diversity of pollen types will be related to the supply of resources in the vertical stratification. And to know the structure of the trophic interactions network of stingless bees (Apidae: Meliponini) from palynological data, works from the Web of Science (WoS) and Scientific Electronic Library Online (SciELO) databases will be consulted from melissopalynological works. carried out with stingless bees in the Amazon between the years 1977 to 2021. All bee species that had their pollen niche studied using the classic protocols of pollen collection and identification will be considered. Data from identification of pollen contained in honey will be discarded, as it is pollen contamination. The results of this bibliographic analysis may indicate which bee species is more generalist, as they collect pollen and nectar in different plant strata. The results of this research are expected to show that all stratification is important for providing floral resources to pollinators. Checking the distribution of floral resources is important because it provides information for the conservation of bees and plants in the area, showing the periods of abundance and scarcity of food, allowing the improvement of management projects in areas with honey potential.
