1. Pollen types used by Centris (Hemisiella) tarsata Smith (1874) (Hymenoptera, Apidae) in the provisioning of brood cells in an area of Caatinga
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 t

2. 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

3. Teste do efeito de borda na predação de ninhos naturais e artificiais no Cerrado
The Cerrado is still one of the most important ecosystems in Brazil, even though more than 50% of its area has been altered or converted to pastureland and plantations. Despite its intense degradation, few ecological processes that might affect its biodiversity have been evaluated. The goal of this study was to test the edge effect on the predation rates at

4. Efeitos da fragmentação sobre o sucesso reprodutivo de aves em uma região de cerrado no Distrito Federal
A fragmentação de habitats é considerada atualmente uma das maiores ameaças à biodiversidade global. A predação e o parasitismo de ninhos são os fatores mais importantes relacionados à perda de espécies de aves em paisagens fragmentadas. Recentemente, uma questão de interesse é testar o efeito que determinadas variáveis exercem sobre a taxa de s

7. Notas sobre a socialidade e a biologia de nidificação de Trypoxylon (Trypoxylon) asuncicola Strand, 1910 (Hymenoptera, Sphecidae)
Twenty-two nests of Trypoxylon asuncicola were sampled in Viçosa, State of Minas Gerais, Brazil, in January 2000 and the occupants' behavior of three nests was registered in 2h of direct observation. 528 brood cells were excavated (24±13.84 SD cells per nest), 129 were reused cells, some of them for seven times (meconium deposit count). The mean number of

8. Aspectos da biologia, estrutura populacional e parentesco intranidal em vespas do gênero Trypoxylon (Hymenoptera: Sphecidae).
Wasps of the genus Trypoxylon (Sphecidae) building their nests with mud and mass-provisioned them with paralyzed spiders. The males of the subgenus Trypargilum may act as guards during the period of nest construction and provisioning. This behavior is common to other Sphecidae, but unusual in Hymenoptera. Theoretically, such behavior makes sense, due to hapl

11. Comunidade de formigas que nidificam em pequenos galhos da serrapilheira em floresta da Amazônia Central, Brasil
Community of ants that nest in dead twigs on the ground of Central Amazonian forest, Brazil. A total area of 2,880 m² in four forest sites, near Manaus, Brazil, was searched for ant colonies nesting in dead twigs on the ground. An amount of 3,706 twigs (0.5-5 cm in diameter) were gathered, of which only 623 (16.8%) had ants, which is equivalent to a density

12. Ecologia comportamental de Ectatomma opaciventre (Formicidae, Ponerinae) : forrageamento e organização social
The ant Ectatomma opaciventre is exc1usively diurnal, restraining theforaging activity at midday. The diet is typically omnivorous, where termites workers and leaf-cutting ants were the most important food items. Contrary to other Ectatomma species, no liquid food like homopteran honeydew or plant nectar was collected. The foragers showed individual foraging
