| 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... |

| ABSTRACT Insect pollination has influenced the evolution and diversification of angiosperms. Consequently, knowing plants used as food sources by bees, the most important pollinator group, is the first step toward understanding how their ecological relationships works. Pollen source information is also highly relevant for bee management and associated fruit and seed production. Accordingly, to improve understanding of the trophic ecology of these bees and their relationships with native Amazonian plants the current study identified, quantified and compared pollen stored in nests of Frieseomelitta stingless bees along the Rio Negro, Amazonas, Brazil. A total of 31 pollen pots were sampled and found to contain 65 pollen types distributed across 52 genera and... |

| Melipona mondury Smith 1863 is an important stingless bee species pollinator and honey/pollen producer, but threatened by fragmentation of habitats throughout its range. This article presents the identification and partial characterization of nesting substrates, bionomic including population features of M. mondury by comparing data between nest architecture of natural beehive and boxes colonies. Nineteen colonies (13 in boxes and six in beehives) were analyzed with regards to substrate nesting, nest characteristics (e.g. length and width of the combs, height and diameter of the pollen and honey jar) and bee population. The average volume and diameter of the trunks cavities used for nesting of M.mondury were18.4 L and 15.8 cm; the average number of combs... |

| Abstract: The aim of this study was to evaluate the diversity of Meliponini and anothers Apiformes (Apidae sensu lato) from a Cerrado fragment and its surrounding. Malaise traps were installed in a pasture near a fragment of Cerrado and its surrounding, from October to December 2010. Samples were collected at seven-day intervals and preserved in Dietrich solution. The apiforms specimens from each sample were separated in morphospecies and sent to identification. The tribe Meliponini was the most abundant in open areas of pasture than in the Cerrado fragment. The Meliponini species present were Trigona gr. fulviventris, Paratrigona lineata, Trigona recursa, Partamona sp, Trigona spinipes, Trigona gr. hyalinata, Trigona gr. fulviventris, Tetragonisca... |

| Flight activity of Plebeia pugnax Moure (in litt.) was studied in six colonies coming from Cunha, SP, from July to October 1994. Twice a week, from 8:00 a.m. to 6:00 p.m., for 5 minutes every half-hour, all the bees entering and leaving the hives were counted. Six hundred counts were made and the materials that foragers carried were recorded. Data were analysed in relation to temperature, relative humidity, light intensity and day time. Foragers' flight activity was relatively constant in a wide range of temperature, from 22°C to 34°C. The minimum temperature for the beginning of flight activity was 14°C. Effective flight activity (when foragers of all colonies were leaving the hives) occurred at 15°C. These bees also flew within a wide range of relative... |

| Flight activity of Melipona bicolor bicolor, coming from Cunha (23º05'S, 44º55'W), Atlantic Forest, was studied in ten colonies, and in two periods: from July to September 1993 and from August to September 1995. The colonies were grouped in weak, medium and strong, according to the diameter of the combs, which can provide a good idea of the number of cells built. 855 observations were accomplished for 5 minutes, every half-hour, from 8 to 18 hours. The total number of bees that entered and left the hive and the number of bees that arrived with mud, pollen and resin, besides the number that went out with debris in that period were counted. It was also registered the temperature and the relative humidity of the air. The total external activity, as well as... |

| In this study, we investigated the chemical composition, and antioxidant and antibacterial properties of ethanolic extracts of propolis (EEP) from Melipona quadrifasciata quadrifasciata and Tetragonisca angustula. Chemical composition of EEP was determined by colorimetry and chromatographic (HPLC-DAD and UPLC-Q/TOF-MS/MS) analysis. Antimicrobial activity of EEP was evaluated against gram-positive (S. aureus, methicillin-resistant S. aureus, E. faecalis) and gram-negative (E. coli and K. pneumoniae) bacteria by the minimal inhibitory concentration (MIC) test using the microdilution method. Furthermore, the growth curve and integrity of cell membrane of S. aureus and E. coli were investigated using standard microbiological methods. HPLC-DAD analysis showed... |

| To contribute to the development of antibacterial products from propolis produced by native Brazilian bees, twenty-nine samples of propolis collected from hives in the state of Minas Gerais, Brazil, were screened for in vitro activity against Aeromonas hydrophila, Bacillus subtilis, Pseudomonas aeruginosa, and Staphylococcus aureus. Among the samples from native Brazilian bees, only that from Frieseomelitta varia (Lepeletier, 1836) inhibited in vitro bacterial growth. Consequently, this propolis underwent fractionation by chromatographic methods monitored through Agar-diffusion assays with these bacteria, which resulted in the isolation and identification of 3,5-diprenyl-4-hydroxycinnamic acid (artepillin C), which showed MIC of 62.5 and 250 µg/mL against... |

| Abstract Honey from stingless bees of the genus Melipona is a well sought product. Nevertheless lack of legal frameworks for quality assessment complicates the evaluation of food safety and marketing of these products. Seeking to assess the quality of honey from the bees of this genus, physical and chemical analyses, identification of phenolic compounds, and microbiological evaluation from six species of stingless bees was performed. The honey samples showed high reducing sugars, low protein levels and a balanced microbiota. High total phenols and flavonoids and higher antioxidant activity were also recorded. Different phenolic compounds of great biotechnological potential were identified and of these apigenin, kaempferol and luteolin were identified for... |

| Abstract This study evidenced the physicochemical composition and antioxidant activity (AA) of honeys (n = 31) and pollen (n = 25) of stingless bees species from Alagoas, Brazil. Fifteen parameters were studied under the light of a multivariate analysis. A dendrogram with three groups of honeys was stablished for the different bees, being the group III formed exclusively by samples from genus Melipona. Plebeia sp. and Tetragona clavipes Fabricius (1804) produced honeys with higher pH/acidity, electrical conductivity, phenolic total and AA. Even different bees from the same meliponary, as M. asilvai and T. clavipes, produced honeys with different AA and chemical profiles, possibly due their different nectar preference. The multivariate analysis of the bee... |

| Rational breeding of stingless bees (or meliponines) is called meliponiculture. In Brazil, studies related to meliponiculture are recent, developed with regional bees. The objective of the study was to elaborate a diagnosis of meliponiculture in Rio Grande do Sul. The data were collected in two stages, the first, through a survey carried out with the extension technicians Emater-RS, and the second, with data collected in a statistically significant sample from the beekeepers. The results show that there are 16,209 families involved in the activity, which have stingless bee hives in their establishment; the number of meliponine hives on rural properties in the state is 80,054 thousand, predominantly in the Northwest mesoregion. The profile of beekeepers is... |

| The genus Trigona contains at least 31 species, but there have been few cytogenetic studies of this group. In this work, four species of Trigona (T. branneri, T. chanchamayoensis, T. hyalinata, and T. recursa) from the municipality of Cuiabá, in the State of Mato Grosso, Brazil, were studied. In all of the species, the females had 2n = 34 chromosomes and the males had n = 17. The C-banding patterns showed that the karyotypes of these species consisted mainly of acrocentric and pseudoacrocentric chromosomes. These cytogenetic findings should useful in future phylogenetic studies of this group. |

| The insect fat body is a multifunctional organ analogous to the vertebrate liver. The fat body is involved in the metabolism of juvenile hormone, regulation of environmental stress, production of immunity regulator-like proteins in cells and protein storage. However, very little is known about the molecular mechanisms involved in fat body physiology in stingless bees. In this study, we analyzed the transcriptome of the fat body from the stingless bee Melipona scutellaris. In silico analysis of a set of cDNA library sequences yielded 1728 expressed sequence tags (ESTs) and 997 high-quality sequences that were assembled into 29 contigs and 117 singlets. The BLAST X tool showed that 86% of the ESTs shared similarity with Apis mellifera (honeybee) genes. The... |
