Estudo do potencial melífero em floresta secundária na micro-região bragantina

Abstract

The traditional model of agriculture in the Brazilian Amazon, based on slash and burn agriculture, is an ecologically destructive way of land use and economically questionable, leading to the impoverishment of the biophysical environment and local populations. In this context, the recovery and search for alternative uses for degraded areas are important issues to be studied. It is estimated that 3/4 of the area of northeastern Pará is composed of secondary forests, locally called "capoeiras". Capoeiras have a high diversity of species and richness of individuals, with great potential as an apicultural flora, which can be a product of great importance for a profitable beekeeping. Through melissopalinology, that is, morphological analysis of the pollen grains in honey, the floral origin of pollen can be defined, providing data for the knowledge of secondary vegetation species that are used by Apis mellifera L. bees and as a subsidy to its management as an economic alternative. This work was conducted in the municipality of Bragança with the objective of identifying the pollen types through melissopalinological analysis of Apis mellifera L. honey and relate them to the secondary vegetation species. Honey samples were collected from hives of local farmers and brought to the laboratories of the Museu Paraense Erru1ioGoeldi- MPEG in Belém-PA, where they were prepared and analyzed the slides that gave as partial results: Borreria verticilata 47.11%, Mimosa pudica 15.19%, Borreria latifolia 16.41% and others 21.29%. Therefore, the results are pointing the pollen of Borreria verticilata as dominant (PD), and of Mimosa pudica and Borreria latifolia as accessory pollen (PA) and the others are isolated pollen (PI).
