Melissopalinologia do mel de Scaptotrigonaaff. xanthotricha Moure, 1950 (Apidae - Apinae - Trigonini)

Abstract

The bees have an important role in conserving biodiversity, such as pollination, since they are pollinated in the ankle of 75% of plant species. Thus, it ensures the maintenance of genetic variability, research and quality of various fruits. The pollen spectrum of honey from Scaptotrigonaaff. xanthotricha was analyzed in order to identify the botanical origin of the floral resources used by this species. The identification of floral origin was performed based on the analysis of pollen types of 9 sizes of honeys collected from the Tapajós Campus meliponary of the Federal University of Western Pará (UFOPA), located in Santarém-PA. The analysis performed followed the standard method using the acetolysis process. Containers of at least 500 pollen grains per sample were made. From the results found, they were calculated as percentages of pollen types and classified according to the relative frequency class. We found 71 pollen types, defined as heterofloral, being the families Fabaceae and Myrtaceae as most representative in the amount of pollen types, and one species most frequent throughout the sampling period for Copaiferamartii. Spondiasmombin, Myracrodruonurundeuva and Triplarisweigeltiana were classified as dominant pollen (PD). Thus, it is important to understand the eating habits of stingless bees, and to know the floral resources heard by them to invest in management techniques that are used to maintain these bees in the colonies.
