| Guilds of Aculeate solitary wasps and bees that nest in preexisting cavities in wood are important components of terrestrial ecosystems because they engage in several ecological interactions (e.g. predation and pollination) with other species of plants and animals. Spatial and temporal variations in richness and abundance of solitary wasps and bees can be related to changes in environmental structure and in the diversity of other groups of organisms. The nesting period of these Aculeata is their most critical life cycle stage. Females of solitary wasp and bee species invest relatively more time constructing and provisioning their nests than do females of social species. Differently from species that nest in the soil or construct exposed nests, the main... |

| Commensalism between Corydalus Latreille, 1802 (Megaloptera, Corydalidae) and Corynoneura Winnertz, 1846 (Diptera, Chironomidae, Orthocladiinae) larvae was recorded in Indaiá stream, at 1,380 m a.s.l. (Parque Nacional da Serra do Cipó, 19º-20ºS, 43º-44ºW) and in the headwaters of São Francisco river, at 1,300-1,700 m a.s.l. (Parque Nacional da Serra da Canastra, 20º00'-20º30'S, 46º15'-47º00'W), in Minas Gerais state, Brazil. Seventy eight Corydalus larvae (range 22-88 mm) were sampled: 61 in the Indaiá stream and 17 in other two streams. Twelve Corydalus larvae (22-79 mm) in the Indaiá stream and three out of 15 larvae in the headwaters of São Francisco river (38-50 mm) had Corynoneura, larvae and pupae on their gills (3rd to 6th) and a few larvae attached... |

| A quantificação anual da disponibilidade de flores de Waltheria americana, da riqueza em espécies e da taxa de visitação de abelhas e vespas às suas flores, permitiu avaliar o potencial dessa invasora para os programas de manejo integrado de pragas e de polinizadores. O estudo foi conduzido em dois locais do Campus da Universidade Federal de Minas Gerais - UFMG (Estação Ecológica e Prefeitura). Em cada local foram registrados mensalmente a produção de flores em 20 indivíduos desta planta, o número de espécies e de visitas de abelhas e vespas às suas flores. Trinta e sete espécies de abelhas e 72 espécies de vespas visitaram as flores de W. americana nos dois locais. A riqueza e o número de visitas de abelhas correlacionaram-se positiva e significativamente... |

| The richness and the composition of bee species at the ecological station of the Universidade Federal de Minas Gerais, Campus Pampulha, Belo Horizonte, MG, Brazil, was recorded from January to December 1996. The bee fauna of the ecological station is rich (98 species) in low-density populations species (350 individuals). The composition of the bee fauna is seasonal (Q = 29.35, df = 11, P < 0.002), however the composition in flowering plants showed no seasonality (Q = 17.30, df = 11, P < 0,099). The bee species visited 23 flowering plant species from 11 families. Asteraceae (111 individuals in 53 species) and Convolvulaceae (88 individuals in 26 species) were the most visited families. There was a positive relation between bee abundance and the number... |

| Temporal variation of solitary wasps and bees, nesting frequency, mortality, and parasitism were recorded from a remanent forest in Belo Horizonte, MG, Brazil. Wasps and bees were collected in trap-nests placed in areas with 25, 100, and 400 m², from February to November 2004. The 137 trap-nests collected contained 11 species of wasps and bees. Wasps occupied most nests (75%). Occupation peaks occurred in March (25%) and September (26%); in June, the lowest occupation (2%) was observed. Except for Trypoxylon (Trypargilum) lactitarse Saussure, no significant correlation was found between number of occupied nests, and temperature and rainfall means. In the nests, 48% of the immature specimens died; 13% of the nests were parasitized. Total death and... |
