| The study was carried out in a 8.2 ha area in an environmental protection area of tropical sea coastal sand dune with "restinga" vegetation in Salvador, Bahia, northeastern Brazil. A total of 1760 bees of Xylocopa (Neoxylocopa) cearensis Ducke, 1910 were netted during the whole year on flowers of 43 plant species belonging to 26 botanic families. The majority of the individuals (79%) concentrated their foraging activity in five plant species. Individuals foraged all day long being the greatest activity between 8 h and 14 h. Similar proportions of young and old bees were sampled over the year. The density of substrates used for nesting was 4.56/ha. In total, 94% of the nests were found in branches of Agaristha revoluta (Spr.) DC. (Ericaceae). The great... |

| The goal of the present study was to identify plant species used as food source, the floral resources utilized, and the insects that visit flowers in a grassland community in southern Brazil. The study was carried out in an area of one hectare, located in a grassland formation in the Parque Estadual de Itapuã, State of Rio Grande do Sul, Brazil. The flowering pattern was seasonal, and richness and abundance of insects was higher during the period of high resource availability. Flowers of 106 species of angiosperms (73 genera and 34 families) were used as source of floral resources for 219 species (2,767 specimens) of insects. A total of 91.5% of plant species were visited by bees, 53.8% by flies, 34.9% by wasps, 22.6% by butterflies, and 12.3% by beetles.... |

| ABSTRACT Floral morphology and biology are important characteristics for plant-pollinator interactions and may influence the behavior of these agents. This study aimed to determine which floral attributes of different melon hybrids influence this interaction and, consequently, their attractiveness in simultaneous crops. The study was conducted in the region of Petrolina, State of Pernambuco (PE)/Juazeiro, State of Bahia (BA) and Mossoró, State of Rio Grande do Norte (RN), in areas with the following melon hybrids: Yellow type, Piel de Sapo, Cantaloupe and Galia. For studies on floral morphology and biology, hermaphrodites and male flowers of each hybrid were analyzed for their size and nectar chamber size, pollen and nectar production, anthesis time and... |

| Centris (Ptilotopus) are large bees and important pollinators in the Neotropical region. Its biology and behavior is still poorly known and only a few observations have been published. In this paper, observations on the biology of C. (Ptilotopus) scopipes Friese, 1899, a species that occurs in the "cerrados" of Brazil, are presented. The study was conducted in the Estação Ecológica de Jataí, in Luiz Antônio, São Paulo, during the active period of the adults (November through April). Females collected pollen from flowers of Solanaceae and Caesalpiniaceae, by vibration, and floral oils from Malpighiaceae belonging to the genera Byrsonima, Banisteriopsis, Stigmaphyllon and Peixotoa. Floral resources are carried in the hind leg scopae to the nests, which are... |

| We applied an "adapted" protocol for collecting and processing pollen grains in the pollen analysis of the post-emergence residue of Melipona (Melikerria) interrupta Latreille. The study was conducted at the Sant'Ana honey farm, located on the banks of the Solimões River, in the municipality of Manacapuru, in the state of Amazonas, Brazil, where a colony was monitored in October and November 2010. From that colony, 10 samples of post-emergence residue were collected. Unlike in the acetolysis method, there was no need to expose pollen grains to an acidic medium, because pollen loses its content during the larval digestive process. We identified 32 pollen types, from 19 botanical families, plus three undetermined pollen types. The most representative family... |

| The aim of this study was to identify, by sediment pollen analysis, the plant species used as floral resources for the provisioning of brood cells in Centris (Hemisiella) tarsata, in an area of Caatinga, within the municipality of Nova Soure, Bahia State, Brazil. The analysis of pollen contents from three brood cells revealed 11 pollen types, corresponding to four botanical families. Malpighiaceae was represented most, followed by Leguminosae, Ochnaceae, and Solanaceae, the latter two represented by just a single pollen type each. On the basis of the percentages in the samples, it was possible to infer that C. tarsata visited distinct plants, but intensified its pollen collection in species related to Aeschynomene martii and Solanum paniculatumpollen... |

| ABSTRACT Varronia curassavica, a subshrubby medicinal species associated with restinga in the Atlantic Forest, has been exploited by local people and the pharmaceutical industry. Indeed, restingas have experienced a continuous process of degradation, and thus, with species and ecosystem both at risk, efforts to support conservation actions are required. The present study aimed to evaluate aspects of V. curassavica reproductive biology. To accomplish this, morphological characterization was performed by monitoring flowering events. The availability of nectar and pollen, as well as the frequency and behavior of floral visitors and dispersers, was also evaluated. This species exhibits both heterostyly and protogyny. Anthesis is diurnal, and flowers last less... |

| The aim of this study was to carry out a survey of the flora with potential for beekeeping in the counties of Ubiratã and Nova Aurora-PR through the collection of plants and pollen analyses in honey samples collected monthly. 208 species of plants were recorded, distributed in 66 families. The families that showed the major richness of pollen types were: Asteraceae, Myrtaceae and Solanaceae. Approximately 80 pollen types were found in honey samples, most of them were characterized as heterofloral. Cultivated plants, such as Glycine max (soybean) and Eucalyptus spp., were representative in some months of the year. Exotic species, such as Ricinus communis and Melia azedarach, were also frequent. However, over than 50% of the pollen types belong to native... |
