| This study examined species richness and relative abundance of eusocial Apidae in an insular region of rain-forest, southeastern Brazil. Sampling took place during one year, using an standardized method with entomological net, at sites of secondary growth habitats surrounded by Atlantic rain-forest. Thirteen species of eusocial Apidae were netted at flowers, over 80% of the captured individuals were meliponine species, although the presence of Apis mellifera, commonly dominant in Brazilian habitats. Foraging activity of these bee species were essentially non-seasonal, apparently affected by high humidity. The patterns in abundance and species richness observed in Ilha Grande differed with other studies conducted at tropical islands, which were... |

| Exfoliated vermiculite is a light-weight and cheap product that, because of its thermal resistance, has become a valuable insulating material. With regard to its use in beekeeping, this research tested whether the box for honey bees constructed with cement-vermiculite mortar (CVM) presents physical characteristics similar to those of wood. The experiment was carried out at Seropédica, RJ, Brazil, for eight months. The cement-vermiculite mortar was compared with a control material (pinewood), in the construction of Langstroth boxes and boards, in a completely randomized design, with respect to thermal control, thermal conductivity and its capacity to absorb and lose water. The production cost for a CVM box was estimated. There were no internal temperature... |

| Abstract Pollen is used in the human diet as a food supplement because of its high nutritional value; however, this product is prone to fungal contamination that could potentially generate toxins that are harmful to human health. This study aimed to verify the floral diversity of commercial brands of bee pollen and their mycotoxicological safety for human consumption. A total of 27 bee pollen samples were analyzed; these samples represented commercial brands, either showing an inspection seal or not, marketed in the State of Rio de Janeiro. The analyzed parameters included floral diversity through palynological analysis, water activity, fungal counts, identification and toxigenic profiles. The palynological analysis identified nine plant families, of which... |

| O estudo foi realizado bimestralmente entre agosto de 2006 e maio de 2007 na Região Sul Fluminense do Estado do Rio de Janeiro. As armadilhas, modelo Carvalho-47, foram adaptadas e posteriormente montadas às 9 horas e retiradas 48 horas depois. Em cada ponto de coleta foram montadas 4 armadilhas, totalizando 20 armadilhas em toda a trilha. Durante o experimento, oito operárias de Lestrimelitta rufipes (Friese) foram capturadas, sendo sete atraídas por salicilato de metila e uma por cineole. Além dessas essências, foram utilizadas mais duas essências, eugenol e vanilina, porém essas duas essências não atraíram nenhum indivíduo. Todas as abelhas foram coletadas ao longo de novembro de 2006. Mesmo com ampla distribuição geográfica, L. rufipes não havia sido... |
