Description
Summary:Regional-level studies of floral resources used by social bees for honey production can contribute to the improvement of management strategies for bee pastures and colonies, by identifying the most visited flowers and thus characterizing the various geographical origins of honey. The objective of this study was to investigate, through pollen analysis, the types of pollen and nectar sources used by the urucu bee (Melipona scutellaris L.) in the North Coast of Bahia. Honey samples were taken monthly from five colonies in an apiary from August 2010 to July 2011. Pollen analysis of honey was performed by using the aceto lysis method, followed by qualitative and quantitative analysis of pollen grains. Fifty pollen types belonging to 40 genera and 17 families were identified. The results indicate predominance of pollen types belonging to the families Fabaceae and Myrtaceae, which suggests that the bees preferred foraging from trees and shrubs. These plants should be included in regional reforestation projects in order to improve management of this bee species and honey production. Keywords: stingless bees, Meliponinae, pollen collection, Atlantic Forest, trophic niche. Estudos em nivel regional dos recursos floristicos utilizados por abelhas sociais para a producao de mel podem contribuir para a melhoria das estrategias de manejo do pasto meliponicola e das colonias, atraves da identificacao das flores mais visitadas, e dessa forma caracterizar a origem geografica do mel. O objetivo desta pesquisa foi investigar, por meio da analise polinica, os tipos de vegetacao fornecedora de nectar e polen para a abelha urucu (Melipona scutellaris L.) no Litoral Norte da Bahia. Foram realizadas coletas quinzenais em 5 colonias de meliponario, de agosto de 2010 a julho de 2011. A analise polinica do mel foi conduzida atraves do metodo da acetolise, seguida por analise quali-quantitativa dos graos de polen. Foram identificados 50 tipos polinicos pertencentes a 40 generos e 17 familias. Os resultados apontam para a dominancia dos tipos polinicos pertencentes as familias Fabaceae e Myrtaceae, sugerindo que essas abelhas preferem forragear em arvores e arbustos. Esses tipos vegetais predominantes devem ser incluidos nos projetos regionais de reflorestamento, visando favorecer o manejo dessa especie de abelha e melhorar a producao de mel. Palavras-chave: abelhas sem ferrao, Meliponinae, coleta de polen, Mata Atlantica, nicho trofico.
