    Melipona scutellaris Latreille, 1811 is of economic importance for local beekeepers, besides its relevance in the pollination of native plant species of the Brazilian Atlantic forest. Currently, data on the use of floral resources by Meliponini colonies are scarce, particularly in urban environments. We evaluated the botanical origin, the microbiological and physicochemical characteristics of pollen stored by M. scutellaris in colonies in an urban environment. The samples (n = 44) were obtained from the metropolitan region of Salvador, Bahia, Brazil, a region of intense urban and industrial activities. We identified 52 pollen types belonging to 21 botanical families. The botanical families Fabaceae, Myrtaceae, and Anacardiaceae represented most pollen types. Aerobic psychrotrophic bacteria, Bacillus spp., molds and yeasts, fecal coliforms, Escherichia coli, Staphylococcus aureus, sulfite-reducing Clostridium, and Salmonella spp. were not found in the samples. We identified and quantified fatty acids with carbon numbers varying from C4 to C20. For the physicochemical parameters, the following variations were verified: moisture (47.3% to 55.70%), ash (3.45% to 5.90%), protein (10.19 to 24.02%), pH (3.28 to 3.99), acidity (237.20 to 557.10 meq/kg), lipids (2.43 to 7.94%), carbohydrates (10.85 to 28.89%) and total energy value (170.60 to 216.99 kcal/100g). Pollen stored (“samburá”) by bees is a complete food and a source of nutrients with therapeutic potential. Pollen stored by M. scutellaris consists of a heterofloral pollen with physicochemical and microbiological qualities, considered safe for human consumption. Moreover, it contains linoleic and linolenic essential fatty acids making it a potential nutraceutical product.

  • Pollen spectrum of honey of Apis mellifera L. and stingless bees (Hymenoptera: Apidae) from the semi-arid region of Bahia State, Brazil
    Publication . Santos, Polyana Carneiro dos; Nascimento, Andreia Santos do; Sodré, Geni da Silva; Carvalho, Carlos Alfredo Lopes de; Alves, Rogério Marcos de Oliveira; Ferreira, Mariza Alves; Andrade, Brunelle Ramos; Caldas, Maiara Janine Machado; Nunes, Lorena Andrade; Estevinho, Leticia M.
    Pollen in honey reflects its botanical origin and melissopalynology is used to identify origin, type, and quantities of pollen grains of the botanical species visited by bees. This study aimed to identify the pollen spectrum of honeys from Apis mellifera and stingless bees produced in the semi-arid region of Bahia, Brazil. We analysed 78 honey samples, which were submitted to the acetolysis process for identification and quantification of pollen types. Fabaceae, Asteraceae and Euphorbiaceae were the most predominant families in pollen types. For Fabaceae, the most representative pollen types were Chamaecrista 1, Mimosa caesalpiniifolia, Mimosa pudica, Mimosa tenuiflora, Prosopis and Senna. The results indicate that the flora explored by the bees to collect nectar is diverse in the semi-arid region of Bahia and the honeys analysed were classified as multifloral.
