| The trap-nesting bees of Guaribas Biological Reserve were studied during one year. Three areas with different vegetation types were sampled, open savanas, closed forest, and a mosaic of these two types. Twelve species of trap-nesting bees were observed, four of which are parasites. The most abundant species were Centris tarsata (Smith, 1879), C. analis (Fabricius, 1804), Tetrapedia diversipes KJug, 1810, and Mesocheira bicolor (Fabricius, 1804). Nesting of Centris tarsata and Mesocheira bicolor occurred mainly during the dry season, while Centris analis and Tetrapedia diversipes did not show any seasonal preferences. Mesocheira bicolar occurred only in the nests of C. tarsata, parasitizing more than 50% of the nests and representing 23.2% of the... |

| The architecture and biology of Euplusia mussitans (Fabricius, 1787) nests were investigated, using trap nests made by wood, which were randomly distributed in a fragment of a coastal sand dunes, in Salvador, Bahia. Brazil (12º56'S and 38º21'W). 10 nests were found in cavities with 1.5 cm in diameter. From them emerged 10 females and 16 males (Sex ratio = 0,38). The nest cells were made of small pieces of bark cemented together with resin. The number of cells in the nests varied from 2 to 4, with females cells at the inner end and males cells towards the entrance. No significant difference was observed (t= 0.7274, P > 0.05) between the medium size for males (6.3 mm ± 0.16) and for females (6.4 mm ± 0.29). The development time of females was longer than... |

| This is the first systematic survey of bees in the Pantanal wetland, Brazil. We recorded bee species and their floral resources within grassland and natural forest edge habitats in the Pantanal. Surveys were conducted during two to four-days per month, for a total of 12 months. Overall, we recorded 56 bee species visiting a total of 63 flowering plants. Asteraceae and Fabaceae presented the highest number of visited species, however Hyptis suaveolens (Lamiaceae) was the plant most visited by different bee species (18). The most generalist native bee was Trigona fuscipennis visiting a total of 17 flowering plant species. Apis mellifera, an exotic bee, visited 27 species. We also report the overlap (37.5%) in the use of floral resources between the exotic... |

| O camu-camu (Myrciaria dubia (H.B.K.) McVaugh, Myrtaceae) é uma fruteira nativa que ocorre nas margens de rios e lagos inundáveis da Amazônia, e está sendo domesticada visando o cultivo em terra firme. O alto teor de ácido ascórbico nos frutos, cerca de 2.800 mg.100g-1 de polpa, fortalece a demanda para consumo no país e exportação. No período de 1997 a 1998, investigou-se a biologia floral e fenologia reprodutiva do camu-camu, em plantios da Embrapa Amazônia Oriental, em Belém, e em áreas de ocorrência natural, em Santarém e Oriximiná, no Estado do Pará, norte do Brasil. Observações diretas sobre o comportamento dos visitantes foram acompanhadas da coleta de espécimens para identificação e registro fotográfico. M. dubia apresenta inflorescências com... |

| ABSTRACT Elaiophores are floral glands that secrete non-volatile oils as a reward for their pollinators. Their secretions mediate a specialized interaction between oil-producing plants and a few species of oil-collecting bees - Apidae and Melittidae. The present review focuses on the morphological and functional aspects of these secretory structures. We also provide information on their chemistry and pollination ecology. Our survey is organized taxonomically among the plant families for which elaiophore occurrence has been confirmed -for the monocots, Iridaceae and Orchidaceae, and for the eudicots, Calceolariaceae, Cucurbitaceae, Krameriaceae, Malpighiaceae, Plantaginaceae, Primulaceae, Scrophulariaceae, Solanaceae and Stilbaceae. Most oil flowers are... |

| A demanda por informações sobre o cultivo da gravioleira na região de Rio Branco, vem aumentando consideravelmente, principalmente no que se refere ao ataque de pragas. O ataque de insetos, afeta a qualidade dos frutos ou inviabilizam a sua comercialização, pela baixa qualidade que apresentam. Os frutos são danificados tanto interna como externamente, sendo que, cm ambos os casos, é comum a ocorrência de patógenos, que agravam ainda mais o problema. Este trabalho teve por objetivo fornecer informações sobre os insetos que se alimentam dos frutos de graviola em Rio Branco, dentro de uma proposta para a definição de wn manejo integrado dessas pragas na Região. |

| Male euglossine bees attracted to cineole, vanillin, methyl salicylate, eugenol and benzyl benzoate, were collected from October 1995 to September 1996, twice a month, between 06.00 and 12.00 hours, at the Companhia Vale do Rio Doce Forest Reserve, Buriticupu-MA. It were sampled 1740 individuals, 37 species and 4 genera. Euglossa was the most abundant genus (23 species), followed by Eufriesea (8), Eulaema (4) and Exaerete (2). The most frequent species were Euglossa pleosticta (33% of the collected individuals), Euglossa truncata (12,7%), Euglossa avicula (6,3%), Eufriesea superba (5,2%), Euglossa fimbriata (4,8%) Euglossa violaceifrons (4,4%), Eulaema nigrita (4,1%), Euglossa cordata (4,0%), Eulaema meriana (3,4%). Cineole attracted 66% of males and 70%... |

| The floral biology of three weeds, Ipomoea cairica, I. grandifolia and I. nil (Convolvulaceae), was studied in Botucatu and Jaboticabal, São Paulo, in southeastern Brazil. The three species are melittophilous, with a varied set of floral visitors, but with some overlapping. Cluster analysis using Jacquard similarity index indicated a greater similarity among different plant species in the same locality than among the populations at different places, in relation to floral visitor sets. The promiscuous and opportunistic features of the flowers were shown, with such type of adaptation to pollination being advantageous to weeds since pollinator availability is unpredictable at ruderal environments. |

| Few studies directly address the consequences of habitat fragmentation for communities of pollinating insects, particularly for the key pollinator group, bees (Hymenoptera: Apiformes). Bees typically live in habitats where nesting substrates and bloom are patchily distributed and spatially dissociated. Bee studies have all defined habitat fragments as remnant patches of floral hosts or forests, overlooking the nesting needs of bees. Several authors conclude that habitat fragmentation is broadly deleterious, but their own data show that some native species proliferate in sampled fragments. Other studies report greater densities and comparable diversities of native bees at flowers in some fragment size classes relative to undisrupted habitats, but find... |

| A higher-level classification of bees, in which the entire group is treated as a single family - the Apidae - is advocated here. A total of seven subfamilies, 51 tribes and 27 subtribes are recognized. These subfamilies correspond to the families adopted in the traditional classification. Although the proposed changes do not involve any major rearrangement, basically only changing the rank given to the main groups, the new system makes the classification of bees more consistent with that adopted for other major groups of aculeate Hymenoptera. It also departs from the 19th century practice, perpetuated in the traditional classification, of giving family-status to the main groups of bees. A correspondence table associating the taxon names used in the current... |

| This paper analyzes the summer and winter total protein content of 7, 14, 21, 28, 35, and 40-day old Apis mellifera L. worker venom glands before (control) and 24 and 96 hours after applying electrical shocks for venom extraction (experimental). During venom extraction, 7-day old workers responded more slowly and weakly to electrical shocks. This response intensifies with age, so that the workers approaching 20 days old respond faster and more aggressively to the shocks. Statistical analysis, using the non-parametric Wilcoxon and Kruskall-Wallis tests and complemented by the Jonckheere test, showed that the protein content varied from one age to another in the experimental group, which was well distinguishable from the values in the control Group in summer... |

| This paper reports the results concerning collection of Euglossinae bees in a mangrove ecosystem in Valença(13º22'08"S and 39º04'20"W), Bahia. These samples were made twice a month, for a year. The chemical baits Citronella, Eucalyptol, Eugenol, Metyl Salicylate and Vanillin attracted 1,144 specimens distributed among twelve species and two genera: Eulaema (Lepeletier, 1841) and Euglossa (Latreille, 1802). The predominam bee species was Eulaema nigrita (Lepeletier, 1841) consisting of 49.4% of the collected specimens, followed by Euglossa cordata (Linnaeus, 1758) with 44.88%, Euglossa imperialis (Cockerell, 1922) with 2.4% and Eulaema meriana flavescens (Friese, 1899) with 1.6%. Theothers species, considering sporadic visitors, Euglossa securigera... |
