Abelhas e vespas solitárias em ninhos-armadilha na Reserva Biológica Guaribas (Mamanguape, Paraíba, Brasil) Zoologia
Aguiar,Antonio José Camillo; Martins,Celso Feitosa.
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...

Analysis of pollen load based on color, physicochemical composition and botanical source Anais da ABC (AABC)
Modro,Anna F.H.; Silva,Izabel C.; Luz,Cynthia F.P.; Message,Dejair.
Pollen load samples from 10 hives of Apis mellifera (L.) were analyzed based on their physicochemical composition and botanical source, considering color as a parameter for quality control. In seven samples it was possible to establish the occurrence of more than 80% of a single pollen type, characterizing them as unifloral but with protein content variation. One of the samples was exclusively composed of saprophytic fungi (Cladosporium sp.). Comparing the mean results of the fungi loads with those of the nutritional components of pollen load, the former presented higher protein, mineral matter and dry matter and lower organic matter, ethereal extract and total carbohydrate values. The monochromatic samples met the physicochemical specifications regulating...

Anti-inflammatory activity of propolis extracts: a review J. Venom. Anim. Toxins
Almeida,E. C. de; Menezes,H..
Since primeval times, the inflammatory process has been described in many different ways. Several anti-inflammatory therapies have been used in different biological models. However, in a recent "back to nature move", modern man is searching for natural products with medicinal properties, particularly those obtained from plants and bees. Propolis has been used in folk medicine for a very long time. The many compounds present in propolis require investigation.Physical-chemical analysis studies have not sufficiently established quality standards of propolis containing products. These standards should depend especially on their different pharmacological activities. There are few studies reporting on the in vitro anti-inflammatory activity of propolis...

Aspectos da biologia de nidificação de Euplusia mussitans (Fabricius) (Hymenoptera, Apidae, Euglossini) Zoologia
Viana,Blandina Felipe; Neves,Edinaldo Luz das; Silva,Fabiana Oliveira da.
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...

Bees (Hymenoptera: Apoidea) and flowers in natural forest patches of southern Pantanal Biota Neotropica
Boff,Samuel; Araujo,Andréa Cardoso; Pott,Arnildo.
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...

Biologia floral e fenologia reprodutiva do camu-camu (Myrciaria dubia (H.B.K.) McVaugh, Myrtaceae) no Estado Pará, Brasil Rev. Bras. Bot.
MAUÉS,MÁRCIA  M.; COUTURIER,GUY.
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...

Calendário floral de plantas melíferas nos assentamentos rurais na fronteira com a Bolívia, Corumbá, MS. Infoteca-e
SALIS, S. M. de; ALMEIDA, A. M. de; REIS, V. D. A. dos; SORIANO, B. M. A.; URBANETZ, C.; AZEVEDO, DAMIÃO TEIXEIRA de.; JESUS, E. M. de.; RODRIGUES, R. da S.; CASTRO, W. J. P..
O calendário floral é uma ferramenta essencial para o adequado planejamento da apicultura, pois identifica quais são os períodos de safra e entressafra de produtos apícolas de determinada região. Por isso, os calendários florais devem ser regionalizados, uma vez que a composição florística e a florada variam de uma localidade para outra, em função das condições edafo-climáticas. Foi elaborado um calendário floral de plantas melíferas para dois assentamentos rurais, Taquaral e Tamarineiro II Sul, na fronteira com a Bolívia, próximos à cidade de Corumbá, para subsidiar o desenvolvimento da produção de mel na região do Pantanal.

Elaiophores: their taxonomic distribution, morphology and functions Acta Botanica
Possobom,Clivia Carolina Fiorilo; Machado,Silvia Rodrigues.
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...

Floral biology and breeding system of three Ipomoea weeds Planta Daninha
Maimoni-Rodella,R.C.S.; Yanagizawa,Y.A.N.P..
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.

Habitat Fragmentation and Native Bees: a Premature Verdict? Ecology and Society
Cane, James H; USDA-ARS; jcane@biology.usu.edu.
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...

Higher-level bee classifications (Hymenoptera, Apoidea, Apidae sensu lato) Zoologia
Melo,Gabriel A. R.; Gonçalves,Rodrigo B..
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...

Histological aspects and protein content of Apis mellifera L. Worker venom glands: the effect of electrical shocks in summer and winter J. Venom. Anim. Toxins
ABREU,R.M.M.; MORAES,R.L.M. SILVA de; MALASPINA,O..
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...

Honeybee venom: influence of collection on quality and cytotoxicity Ciência Rural
Abrantes,Allyson Fortunato; Rocha,Thayse Cavalcante da; Lima,Amanda Beatriz Sales de; Cavalcanti,Mônica Tejo.
ABSTRACT: Apitoxin is the venom produced by bees. It is a complex chemical compound, rich in protein substances and with pharmacological effects. This study was carried out with the objective of comparing the quality of apitoxin extracted in an apiary in different parts of the collector in relation to moisture content, protein analysis and cytotoxicity assay with Artemia salina L. Type 1 apitoxin was collected from glass slabs at the entrance to the hive, while type 2 apitoxin was collected from the waste accumulated in the collection rods and treated by rinsing in distilled water. Both apitoxins presented significant differences (P>0.05) in relation to protein profile, with type 1 showing a higher content (77.8%) than type 2 (51.9%), and presented...

Influence of landscape structure on Euglossini composition in open vegetation environments Biota Neotropica
Moreira,Eduardo Freitas; Santos,Rafaela Lorena da Silva; Silveira,Maxwell Souza; Boscolo,Danilo; Neves,Edinaldo Luz das; Viana,Blandina Felipe.
Abstract The fauna of Euglossini bees is poorly known in savanna regions, making it difficult to understand how these bees use open vegetation environments. The aim of this study was to evaluate the influence of landscape structure on species abundance and composition of Euglossini bees in naturally heterogeneous savanna landscapes. Nine sites were sampled monthly using six traps with chemical baits. Three aromatic essences (eucalyptol, methyl salicylate and vanillin) were used to attract the Euglossini. Surrounding environmental conditions were measured using three independent variables, calculated in multiple scales: index of local vegetation and two landscape indices (Shannon Diversity and area-weighted shape). We compared the competing hypotheses...
