1. Floral visitors of canola (Brassica napus L.) hybrids in Cerrado Mineiro region, Brazil
RESUMO: O objetivo deste estudo foi verificar os visitantes florais de canola na região do Triângulo Mineiro, Minas Gerais, Brasil. Utilizou-se um delineamento experimental de blocos inteiramente randomizados com dois híbridos e 10 amostras replicadas, totalizando 20 amostras. A pesquisa de visitantes florais foi feita durante 10 dias. As análises fauní

2. Bees Diversity on Flowers of Eremanthus spp. (Asteraceae)
ABSTRACT Bees are considered important pollinators due to their fidelity to plants, enabling the maintenance of gene flow between plant species. The objective of this study was to recognize the visit of bees in two Candeia species, Eremanthus erythropappus and Eremanthus incanus (Asteraceae), as well as to analyze the pollen content carried by bees in a rege

3. Brazilian stingless bee propolis and geopropolis: promising sources of biologically active compounds
ABSTRACT Stingless bee products such as honey, pollen, propolis, and geopropolis have been used for centuries in traditional medicine for the treatment of several illnesses. Investigation of the biological activity of stingless bee products, especially propolis and geopropolis, has revealed promising therapeutic properties. About 20% of total Neotropical sti

4. A new technique in the excavation of ground-nest bee burrows (Hymenoptera: Apoidea)
ABSTRACT Bees have a diversified natural history, thus the methods applied to study such diversity are varied. When it comes to studies of nesting biology, bees which nest in pre-existing cavities have been reasonably well studied since researchers started using trap-nests. However, bees whose nests are built underground are poorly studied due to the difficu

5. Isolation of biologically active peptides from the venom of Japanese carpenter bee, Xylocopa appendiculata
Abstract Background Mass spectrometry-guided venom peptide profiling is a powerful tool to explore novel substances from venomous animals in a highly sensitive manner. In this study, this peptide profiling approach is successfully applied to explore the venom peptides of a Japanese solitary carpenter bee, Xylocopa appendiculata (Hymenoptera: Apoidea: Apida

6. Bee assemblage in habitats associated with Brassica napus L.
ABSTRACTAssessments in agricultural crops indicate that alterations in the landscape adjacent to the crops can result in reduced productivity due to loss or low abundance of pollinating agents. In the canola crop, production is partially dependent on insect pollination. Therefore, knowledge of the faunal diversity within and near crop fields is key for the m

7. An overview on pollination of the Neotropical Poales
Abstract Current phylogenetic hypotheses support that ancestral Poales were animal-pollinated and that subsequent shifts to wind pollination have occurred. Ten of the 16 Poales families are widely distributed in the Neotropics, however a comprehensive understanding of their pollination systems' diversity is still lacking. Here we surveyed studies on pollinat

8. Changes in wild bee fauna of a grassland in Brazil reveal negative effects associated with growing urbanization during the last 40 years
Bee fauna and associated flora from a grassland site in Brazil, surveyed 40 and 20 years ago, were newly surveyed with comparable methodology to evaluate changes in the bee fauna of this site, considering that human population and urbanization has exponentially increased in the last 40 years. In general, bee species richness has declined in 22%, as well as t

9. Biologia reprodutiva de rainhas e machos de Tetragonisca angustula (Hymenoptera: Meliponini) / Reproductive biology of the queens and males of Tetragonisca angustula (Hymenoptera: Meliponini)
The stingless bees (Hymenoptera: Meliponini)present a haplodiploid sex determination system with complementary sex determination in a single locus. Such a system is a large genetic load for the group and thus the genetic diversity of male\ s aggregations near the nests is essential to minimize the chances of inbreeding. The interactions among the stingless b

10. Diversidade de fontes de pólen utilizadas por abelhas Centridini em áreas de Cerrado / Diversity of pollen sources used by Centridini bees in areas of Cerrado. Dissertation in Ecology and Conservation of Natural Resources
As abelhas nativas são os principais responsáveis pela polinização em áreas naturais e nos sistemas agrícolas. Nesse contexto, informações sobre as fontes de recursos alimentares e os padrões de utilização dessas por abelhas simpátricas podem subsidiar ações de conservação e manejo desse grupo. Nesse trabalho apresentamos informações sobre

11. Determinantes da densidade e distribuição de ninhos e diversidade de espécies de meliponíneos (Apidae, Meliponini) em áreas de cerrado de Itirapina, SP / Determinants of stingless bees (Apidae, Meliponini) nest density and distribution and species diversity in cerrado areas of Itirapina, SP
A pressão antrópica sobre o cerrado vem transformando sua paisagem em um mosaico de fragmentos naturais imersos em uma matriz antropizada. A qualidade da vegetação dos fragmentos remanescentes depende em grande parte das populações de polinizadores, dos quais as abelhas são o grupo mais representativo. As abelhas sem ferrão (Apidae: Meliponini) comp�

12. Abelhas visitantes florais, potenciais polinizadoras do algodoeiro (Gossypium hirsutum L.) em cultivo agroecolÃgico / Bees floral visitors, potential pollinators of cotton (Gossypium hirsutum L.) in agro-ecological farming
This study was conducted in July 2010 in the town of ChorÃ- CE, to evaluate the bees visiting the flowers of cotton (Gossypium hirsutum L. cv. CNPA - 7MH) in two agroecological crops. To do so, assessed the diversity of insects in two areas, their frequency, foraging behavior and potential pollinators of the culture, and studied the floral biology and polli
