A new cluster-brood building species of Plebeia (Hymenoptera, Apidae) from eastern Brazil Rev. Bras. entomol.
Melo,Gabriel A. R.; Costa,Marco A..
A new species of Plebeia, the second largest genus of stingless bees in the Neotropical region, is described from eastern Brazil. Plebeia grapiuna sp. nov., known only from the lowland forests of southern Bahia, is most similar to P. lucii Moure, a species recently described from Minas Gerais. The lack of yellow marks and the smoother integument of the frons and mesoscutum in P. grapiuna sp. nov. distinguish them. Main features of the nesting habits of the new species are described and illustrated.

Antibacterial activity of propolis produced by Frieseomelitta varia Ciência e Agrotecnologia
Campos,Viviane Aparecida Costa; Santos Júnior,Helvécio Martins dos; Oliveira,Denilson F; Carvalho,Hudson Walace Pereira de; Machado,Alan Rodrigues Teixeira; Tirelli,Aline Auxiliadora.
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...

Aprendendo a conviver com as abelhas-arapuás em sistemas agrícolas. Infoteca-e
DRUMOND, P. M.; RIBEIRO, M. de F.; KIILL, L. H. P.; SANTOS, R. S..
Apesar dos inúmeros benefícios associados às abelhas-sem-ferrão, algumas espécies são consideradas pragas agrícolas (como as arapuás, por exemplo), por danificarem caules, flores, folhas e/ou frutos, facilitando a entrada de organismos causadores de doenças, prejudicando o desenvolvimento das plantas, bem como reduzindo a quantidade e o valor comercial dos frutos. Esta publicação reúne algumas medidas que podem auxiliar os produtores rurais a minimizar os impactos negativos causados pelas abelhas-arapuás e a conviver com esse grupo de insetos, o qual desempenha importante papel no ecossistema.

Can climate shape flight activity patterns of Plebeia remota Hymenoptera, Apidae)? Iheringia, Sér. Zool.
Hilário,Sergio D.; Ribeiro,Márcia de F.; Imperatriz-Fonseca,Vera L..
Flight activity of foragers of four colonies of Plebeia remota (Holmberg, 1903) was registered from December 1998 to December 1999, using an automated system (photocells and PLC system). The colonies originated from two different regions: Cunha, state of São Paulo, and Prudentópolis, state of Paraná, Brazil. Flight activity was influenced by different climatic factors in each season. In the summer, the intensity of the correlations between flight activity and climatic factors was smaller than in the other seasons. During the autumn and winter, solar radiation was the factor that most influenced flight activity, while in the spring, this activity was influenced mainly by temperature. Except in the summer, the various climatic factors similarly influenced...

Comparative study of wax glands in four Meliponini bees (Hymenoptera, Apidae) producing different quantities of wax Iheringia, Sér. Zool.
Cavalcante,Vagner Melo; Oliveira,Vagner Tadeu Paes de; Cruz-Landim,Carminda da.
The developmental degree of the wax glands was compared in four Meliponini bees, that produce different quantities of wax. The histological data and height average of the wax epithelium during the time in which the maximum production of wax is expected, are in accordance with the rates of wax produced by the species. In Lestrimelitta limao (Smith, 1863) a species which has cleptobiotic habits, and frequently rob wax from the attacked colonies, the height of wax epithelium was the lowest among the studied species. The cells seem to show an abnormal vacuolated cytoplasm, in the phase in which they would be producing wax.

Comparative study on the use of specific and heterologous microsatellite primers in the stingless bees Melipona rufiventris and M. mondury (Hymenoptera, Apidae) Genet. Mol. Biol.
Lopes,Denilce Meneses; Campos,Lúcio Antônio de Oliveira; Salomão,Tânia Maria Fernandes; Tavares,Mara Garcia.
Due to their high degree of polymorphism, microsatellites are considered useful tools for studying population genetics. Nevertheless, studies of genetic diversity in stingless bees by means of these primers have revealed a low level of polymorphism, possibly the consequence of the heterologous primers used, since in most cases these were not specifically designed for the species under consideration. Herein we compared the number of polymorphic loci and alleles per locus, as well as observed heterozygosity in Melipona rufiventris and M. mondury populations, using specific and heterologous primers. The use of specific primers placed in evidence the greater frequency of polymorphic loci and alleles per locus, besides an expressive increase in observed...

Cytogenetic characterization of Melipona rufiventris Lepeletier 1836 and Melipona mondury Smith 1863 (Hymenoptera, Apidae) by C banding and fluorochromes staining Genet. Mol. Biol.
Lopes,Denilce Meneses; Pompolo,Sílvia das Graças; Campos,Lúcio Antônio de Oliveira; Tavares,Mara Garcia.
The stingless bees Melipona rufiventris and M. mondury were analyzed cytogenetically by conventional staining with Giemsa, C-banding and sequential staining with the fluorochromes CMA3/DA/DAPI. Both species presented 2n = 18 and n = 9, except for one colony of M. rufiventris, in which some individuals had 2n = 19 due to the presence of a B chromosome. After Giemsa staining and C-banding the chromosomes appeared very condensed and presented a high heterochromatic content, making it difficult to localize the centromere and therefore to visualize the chromosomes morphology. The constitutive heterochromatin was located in interstitial chromosome regions covering most of the chromosomes extension and consisted mainly of AT, as shown by DAPI staining. The...

Estudo dos custos e viabilidade econômica do sistema para produção de mel de abelhas-indígenas-sem-ferrão, no Estado do Acre. Infoteca-e
SA, C. P. de; BAYMA, M. M. A.; PINHO, E. A. de C.; DRUMOND, P. M..
No Brasil, a criação racional de abelhas-indígenas-sem-ferrão ou meliponicultura vem crescendo rapidamente, saindo do estágio extrativista, ou de criação rudimentar, para o uso de colmeias racionais e adoção de boas práticas agrícolas. Embora a meliponicultura seja amplamente divulgada como uma atividade de retorno financeiro garantido, não existem na literatura muitos trabalhos demonstrando a sua viabilidade econômica. Este estudo teve como objetivo avaliar o desempenho econômico de um meliponário, constituído por 50 colônias de abelhas-sem-ferrão conhecidas como uruçus (Melipona spp.).

Mascena,Valdenio Mendes; Silva,Celso Moreira; Almeida,Cicero Lima de; Alves,Társio Thiago Lopes; Freitas,Breno Magalhães.
ABSTRACT This study evaluated the influence of the environment and of two models of beehive (wooden box and ceramic pot) on the flight activity of the ground-nesting bee, Melipona quinquefasciata. The experiment took place in the Chapada do Araripe, in the State of Ceará, Brazil, between July 2014 and June 2015. The study followed colonies in three ceramic pots and four wooden boxes. Observations of the flight activity of the bees and of the climate were made on five days every month, each colony being monitored for 5 min, at intervals of one hour, from 0500 to 1700. The internal temperature and relative humidity of the hives were also recorded every hour throughout the year. The temperature correlated positively with the bees' entering and leaving the...

Genetic divergence between Melipona quadrifasciata Lepeletier (Hymenoptera, Apidae) populations Genet. Mol. Biol.
Tavares,Mara Garcia; Pietrani,Nathalia Teixeira; Durvale,Maxwell de Castro; Resende,Helder Canto; Campos,Lucio Antonio de Oliveira.
Melipona quadrifasciata is a stingless bee widely found throughout the Brazilian territory, with two recognized subspecies, M. quadrifasciata anthidioides, that exhibits interrupted metasomal stripes, and M. quadrifasciata quadrifasciata, with continuous metasomal stripes. This study aimed to estimate the genetic variability of these subspecies. For this purpose, 127 colonies from 15 Brazilian localities were analyzed, using nine species-specific microsatellite primers. At these loci, the number of alleles ranged from three to 15 (mean: 7.2), and the observed heterozygosity (Ho) ranged from 0.03-0.21, while the expected heterozygosity (He) ranged from 0.23-0.47. The genetic distances among populations ranged from 0.03-0.45. The F ST multilocus value (0.23)...

Allozyme, microsatellite and random amplified polymorphic DNA (RAPD) molecular markers were used to investigate the within and between population genetic variability and between population genetic differentiation of the Brazilian stingless bee uruçu amarela (nominally Melipona rufiventris Lepeletier, 1836) present in savanna and Atlantic forest habitats of the Brazilian state of Minas Gerais (MG). We found low levels of within population variability, although there were a large number of private alleles that specifically characterized these populations. The F ST values indicated a high level of genetic diversity between populations. Analysis of molecular variance (AMOVA) showed a high degree of population differentiation between the savanna and Atlantic...
