1. Nesting and reproductive habits of the solitary bee Centris analis in trap nests under a tropical climate
RESUMO A polinização é um fator essencial na produção agrícola mundial e existe a necessidade de aumentar o número de espécies de abelhas que podem ser criadas para a polinização na agricultura, como a abelha solitária coletora de óleo Centris (Heterocentris) analis (Fabricius, 1804). Aqui, os comportamentos de nidificação e reprodutivo dessa a

2. Peptidomic analysis of the venom of the solitary bee Xylocopa appendiculata circumvolans
Abstract Background: Among the hymenopteran insect venoms, those from social wasps and bees - such as honeybee, hornets and paper wasps - have been well documented. Their venoms are composed of a number of peptides and proteins and used for defending their nests and themselves from predators. In contrast, the venoms of solitary wasps and bees have not been

3. 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

4. Phylogeny and new species of the Neotropical bee genus Paroxystoglossa Moure (Hymenoptera, Apoidea)
ABSTRACT Paroxystoglossa is a solitary, ground-nesting bee genus. It was revised in 1960 and currently includes nine species from Argentina, Brazil and Paraguay. The objectives of this contribution are to provide a morphological phylogeny for the group and to describe two new species: P. levigata n.sp. and P. mourella n.sp. Paroxystoglossa is monophyletic an

5. Specialized diet of the solitary bee Epicharis rustica (Apoidea, Centridini): importance of the tree Byrsonima sericea
ABSTRACT Collection of pollen was verified in 248 samples of the material on the hind tibial scopae of the solitary bee, Epicharis rustica (Olivier, 1879) captured on their return to the nest. Of the total, 54% (133) of the samples had material on the scopae, 48 of then had only oil and 85 (64%) had both oil and pollen. For seven weeks, almost all (91%) of t

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. Manejo de abelhas do gênero Xylocopa (Apidae, Xylocopini) para incremento da frutificação do maracujá-amarelo (Passiflora edulis f. flavicarpa Degener)
A produtividade do maracujá-amarelo não atinge níveis ideais em áreas com baixa densidade ou ausência de seus polinizadores efetivos, abelhas do gênero Xylocopa. Estas abelhas apresentam tamanho e comportamento de forrageamento adequados para a polinização do maracujá-amarelo e são facilmente atraídas por ninhos-armadilha. O objetivo deste trabalh

8. 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

9. Nidificação de abelhas e vespas solitárias e biologia reprodutiva de Megachile dentipes Vachal (Hymenoptera, Megachilidae) em ninhos-armadilha
Terrestrial ecosystems, solitary bees and wasps play important roles as pollinators, predators and parasites. Most part of the life of these Hymenoptera is designed to aspects related to nesting, including the search of the nest site, nest construction and food collection to rear the larvae. However, in natural environments the nests of these insects are dif

10. Morphometric Analysis of Populations of Centris aenea Lepeletier (Hymenoptera: Apidae) from Northeastern Brazil
Centris aenea Lepeletier is a solitary bee that has raised interest in management to pollinate crops, such as acerola, Malpighia emarginata. This study investigated the level of morphometric variability among populations of C. aenea from Northeastern Brazil. Traditional and geometric morphometric analyses were used. Head length, leg length, wing length, and

11. A ocorrência de Apiformes (Hymenoptera) em fragmentos da Mata Atlântica e respostas ecológicas para seu desenvolvimento sustentável. / The occurrence of Apiforms (Hymenoptera) in fragments of Atlantic Rainforest and ecological responses for sustainable use.
The high species richness of the Atlantic and Amazon rainforests places Brazil as one of the most important repositories of biological diversity worldwide. Unfortunately, some of these protected areas were rapidly degraded. Deforestation, cattle and agriculture expansion, the spread of exotic species are listed as key factors that mitigate the environmental.

12. Morphology of male reproductive system of two solitary bee species (Hymenoptera: Apidae)
Bees can form all levels of social organization, from solitary to advanced eusocial societies. Although 80% of the species exist as solitary species, most researches emphasize social species. This study focuses on the description of the male reproductive system of the solitary beesThygater analis (Lepeletier) and Melitoma segmentaria (Fabricius) and searches
