| A presença de abelhas em culturas de valor comercial, no período de florescimento, é importante não apenas para garantir a polinização cruzada, quando indispensável, mas também para incrementar a produção de frutos e sementes. Nessa perspectiva, o presente trabalho teve a finalidade de identificar as abelhas visitantes das flores em pomar de laranjeira (Citrus sinensis) e tangerineira (Citrus reticulata) em Salinas - MG. O trabalho foi conduzido na fazenda experimental Santa Isabel, da Escola Agrotécnica Federal de Salinas - MG, em pomares de laranjeira com as variedades, pera, baía e baianinha, e de tangerineira, variedade poncã. As coletas das abelhas visitantes das culturas da laranjeira e tangerineira foram feitas nas floradas principais, entre os... |

| 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 their abundance. Some of the previously abundant species are now absent, including Bombus bellicosus Smith, 1879, Gaesischia fulgurans (Holmberg, 1903) and Thectochlora basiatra (Strand, 1910). No particular trend of differential decrease among either taxonomic or functional groups was observed, except for a minor increase in the proportion of oligolectic species and a 50% reduction in the number of... |

| Four places in Latin-America have Melipona Illiger, 1806 beekeeping: Mexico, with M. beecheii Bennet, 1831; Northeast Brasil, with M. scutellaris Latreille, 1811; Maranhão State (Brazil) with M. compressipes fasciculata Smith, 1854; Venezuela, in her coast, with M. favosa (Fabricius, 1798). Natural colonies of M. compressipes fasciculata occupied tree holes ranging from 6,5 to 24 1. The average honey production of 60 colonies in hives with capacity of 50.2 1, 41.0, 30.2, 16.5 and 6.2 were respectively 8.4, 6.5, 5.5, 3.3 and 2.0 Kg. Due to lack of bee flowers within the city limits, hives with a volume of 27 1 (30x30x30 cm) were used successfully in our future experiments with M. compressipes fasciculata instead of the ideal size of 40 to 50 liters, since... |

| A really beautiful Euglossinae bee, Euglosssa (Euglossella) perpulchra sp. n., is decribed from Pernambuco, Igarassu, Brazil. It can be recognized by the following characters: head and thorax bronzeous green covered with fulvous pubescence, and abdomen bluish with white marginal bands narrowed progressively from second to sixth tergum; wings slightly fulvous, stigma and wing venation light fulvous. It is closely related to E. decorata Smith, 1874 and E. singularis Mocsáry, 1899. |

| Three nests of Euglossa (Glossura) annectans Dressier, 1982 were obtained from trap nests at Serra do Japi, Jundiai, São Paulo State, Brazil. The bees nested in bamboo cane (one nest) and in wooden-boxes (two nests). Solitary (two cases) and pleometrotic (one case) foundations were observed. Two nests were re-used once by two females working in each of them. Re-using females that shared the nests were of the same generation and each built, provisioned and oviposited in her own cells, characterizing a communal association. The brood development period was related to climatic conditions. Natural enemies included Anthrax oedipus oedipus Fabricius, 1805 (Bombyliidae), Coelioxys sp. (Megachilidae) and Melittobia sp. (Eulophidae). |

| Collection data of Euglossinae males from Parque Estadual do Rio Doce (PERD) and Viçosa, both areas with remnants of Atlantic Rain Forest (Mata Atlântica) in Minas Gerais state, Brazil are presented. Comparisons made among three fragments with different sizes and states of disturbance from Viçosa showed differences in abundance of most common species and apparently, Eulaema nigrita Lepeletir, 1841 can be an useful indicator of disturbed sites. Some populations of euglossine bees seems to be restrict to a forest fragment, there being few or no flow of individuals or species of one fragment to another, even when they are only 1 km apart. 15 species of euglossines were sampled in PERD, and the most abundant was Eulaema cingulata (Fabricius, 1804). At Viçosa,... |

| It was compared body size (measured as intertegular span) variance of trapped-males of Eulaema nigrita Lepeletier, 1841 sampled in dry (July, August and September) and wet (December, January and February) seasons of the years 1988/89 and 1994/95 in Viçosa (Minas Gerais, Brazil). It was also compared the body size variance between males and females sampled in three nests found in São Carlos (São Paulo, Brazil) and between these males and trapped ones. The smaller male (6.4 mm) was sampled in June and the bigger (8.9 mm) in July 1994, but the majority (32.3%) showed an intertegular span ranging from 7.8 to 8.0mm. The observed variance in body size was similar between males sampled in nests and trapped-males and the variance found inside a nest was similar... |

| Males of Euglossa mandibularis Friese, 1899 can be categorized by (1) presence or (2) absence of scutellar tuft (a morphological feature of dense setae found in females' scutellum of the genera Euglossa Latreille, 1802 and Eulaema Lepeletier, 1841). A multivariate statistical analysis using six morphological measures (hindtibia length and width, head width, intertegular span, midbasitarsus length and scape length) show that males of the categories 1 and 2 were significantly different in relation to such measures. The width head, hindtibia length and scape length were the measures that most influenced the observed differences. Levene test suggest there is not effect of stabilizing selection on males without scutellar tuft. Since there is a fluctuation in... |
