The Native Bee Fauna of Carlinville, Illinois, Revisited After 75 Years: a Case for Persistence
Provedor de dados: 7
Autores: Marlin, John C; Illinois Waste Management and Research Center; marlin@uiuc.edu; LaBerge, Wallace E; Illinois Natural History Survey; wlaberge@inhs.uiuc.edu.
As a follow-up to the observations of Charles Robertson from 1884 to 1916, we revisited the Carlinville, Illinois, area between 18 August 1970 and 13 September1972 to sample and identify bee species (Hymenoptera: Apoidea). We concentrated on collecting nonparasitic bees (and excluded Apis and Bombus) visiting 24 plant species that bloomed at various times of the year, and upon which Charles Robertson found many bee species. For example, we collected most intensively on spring-blooming Claytonia virginica and fall-blooming Aster pilosus, upon which Robertson reported 58 and 90 bee visitors, respectively. Bees were also collected on an opportunistic basis at some other plants. We updated the species names used by Robertson for revisions and synonymies. This...

Habitat Fragmentation and Native Bees: a Premature Verdict?
Provedor de dados: 7
Autores: 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...

Ups and Downs in Pollinator Populations: When is there a Decline?
Provedor de dados: 7
Autores: Roubik, David Ward; Smithsonian Tropical Research Institute; roubikd@tivoli.si.edu.
Plant-pollinator systems inherently possess wide variation that limits the applicability of surveys on population dynamics or diversity. Stable habitats are scarcely studied, whereas dynamics in unprotected habitats are less predictable or more compromised by exotic organisms (Apis, in the case of bee surveys). An extensively replicated, long-term study of orchid-bees (Euglossini) was made in protected tropical moist forest in Panama. Over 47,000 bees were recorded in 124 monthly censuses employing 1952 counts. No aggregate trend in abundance occurred (from 1979 to 2000), although four individual species declined, nine increased, 23 showed no change, and species richness was stable. No rare or parasitic species showed decreasing trends, while the most...

Organization of the cysts in bee (Hymenoptera, Apidae) testis: number of spermatozoa per cyst
Provedor de dados: 76
Autores: Cruz-Landim,Carminda da.
The morphology of the cyst cells in Apis mellifera Linné, 1758, Scaptotrigona postica Latreille, 1804, and Melipona bicolor bicolor Lepeletier, 1836 testis, as well as the average number of spermatic cells are reported. The data indicates a supporting and nourrishing role of the cyst cells to the developing cystocytes. The counts of immature spermatozoa in the cysts show an average of 202.8 ± 21.2 spermatozoa for A. mellifera, 117.4 ± 8.68 for S. postica and 88.8 ± 15.57 for M. bicolor, which predict the occurrence of 8 mitotic cycles in the cystocytes of A. mellifera and 7 in the meliponines, considering that only one spermatozoom originates of each final spermatogonium.

Anti-inflammatory activity of propolis extracts: a review
Provedor de dados: 79
Autores: 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...

Histological aspects and protein content of Apis mellifera L. Worker venom glands: the effect of electrical shocks in summer and winter
Provedor de dados: 79
Autores: 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...

Lesions caused by Africanized honeybee stings in three cattle in Brazil
Provedor de dados: 80
Autores: Caldas,Saulo Andrade; Graça,Flávio Augusto Soares; de Barros,Júlia Soares Monteiro; Rolim,Márcia Farias; Peixoto,Tiago da Cunha; Peixoto,Paulo Vargas.
We report three cases of stings by Africanized bees in cattle in the state of Rio de Janeiro, Brazil. Erythema, subcutaneous edema, necrosis accompanied by skin detachment, and subsequent skin regeneration were observed, especially on the head and dewlap. Histopathological examinations performed 45 days later revealed complete skin reepithelialization with moderate dermal fibrosis. The clinical picture and differential diagnosis are discussed in the present manuscript, with a focus on photosensitization, which causes cutaneous lesions on the head (sequela) with cicatricial curving of the ears and can be very similar to what is observed in cattle attacked by swarms of bees. The distinction between photosensitization and bee sting lesions can be made with a...

Possible chemical mimicry of the European lady’s slipper orchid (Cypripedium calceolus)
Provedor de dados: 16
Autores: Przybyłowicz, T.; Roessingh, P.; Groot, A.T.; Biesmeijer, J.C.; Oostermijer, J.G.B.; Chittka, L.; Gravendeel, B.
Pollination based on insect deception has been debated in the scientific community since it was first reported over two hundred years ago. A vast majority of deceptive syndromes occur within the orchid family. While many cheating flowers have been described and are well known, there are still many curious cases that need further investigation. One prime example of such a case is Cypripedium calceolus, known as European lady’s slipper orchid. While the flower has been of interest to many prominent scientists for over a century, its pollination is still not fully understood. Both visual and olfactory cues seem to play an important role in pollinator attraction. In this study we focussed on the olfactory cues in order to explore their relationship (in future...

Floral biology and breeding system of three Ipomoea weeds
Provedor de dados: 87
Autores: 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.

Pollination biology in Jacaranda copaia (Aubl.) D. Don. (Bignoniaceae) at the "Floresta Nacional do Tapajós", Central Amazon, Brazil
Provedor de dados: 88
Autores: Maués,Márcia Motta; Oliveira,Paulo Eugênio A. M. de; Kanashiro,Milton.
Jacaranda copaia (Aubl.) D. Don is a pioneer tree widespread in the Brazilian Amazon, usually found colonizing forest gaps and altered areas, and the forest fragment edges. This study investigated aspects of the floral biology, breeding system and pollinators of J. copaia trees. Flowering lasts from August to November, during the low rainfall period extending up to four weeks per tree and 3-4 months for the population as a whole, characterizing a cornucopia flowering pattern. The fruit set ends in the beginning of the rainy season, with wind dispersed winged seeds. Fruit set from open pollination was 1.06% (n = 6,932). Hand pollination using self-pollen (n = 2,099) did not set fruits. Cross-pollination resulted in 6.54% fruit set (n = 2,524), representing...

Nest descriptions of Megalopta aegis (Vachal) and M. guimaraesi Santos &amp;amp; Silveira (Hymenoptera, Halictidae) from the Brazilian Cerrado
Provedor de dados: 92
Autores: Santos,Leandro M.; Tierney,Simon M.; Wcislo,William T.
We present the first data on the nesting biology of Megalopta aegis and M. guimaraesi from southeastern Brazil. Nests were collected in the Área de Proteção Ambiental Água Limpa, Bauru, São Paulo state. Our data suggest that nest architecture is conserved throughout all species of Megalopta. Two nests of M. guimaraesi consisted of a single female with brood. Of three M. aegis nests, two contained single females with brood and the third nest contained three adult females, with three times more brood than any single female nest. This observation suggests that social behavior in M. aegis is facultative, as known for other Megalopta species.

Pollinator guild organization and its consequences for reproduction in three synchronopatric species of Tibouchina (Melastomataceae)
Provedor de dados: 92
Autores: Franco,Ana Maria; Goldenberg,Renato; Varassin,Isabela Galarda.
Pollinator guild organization and its consequences for reproduction in three synchronopatric species of Tibouchina (Melastomataceae). In co-flowering plant species, pollinator sharing can result in interspecific pollen transfer and fecundity reduction. Competition will be relaxed whenever there is a large amount of initial pollen supply or if each plant species occupies different habitat patches. Reproduction in Tibouchina cerastifolia (Naudin) Cogn., T. clinopodifolia (DC.) Cogn. and T. gracilis (Bonpl.) Cogn. was studied in an area of Atlantic rainforest to examine whether synchronopatry induces time partitioning among pollinator species. Eleven bee species comprised the pollinator guild. Among pollinators, there were overlaps in bee species composition...

Phylogeny of the Augochlora clade with the description of four new species (Hymenoptera, Apoidea)
Provedor de dados: 92
Autores: Gonçalves,Rodrigo Barbosa.
ABSTRACT The Augochlora clade includes four genera: Augochlora Smith, Augochlorella Sandhouse, Ceratalictus Moure, and Pereirapis Moure. This is one of the richest and most widespread groups of Augochlorini bees. There are about 150 species, which occur from Argentina to Canada. The species of Augochlora clade are considered solitary to facultatively social, except Ceratalictus for which nothing is known. Wood nesting behavior arose once in the clade, in Augochlora sensu strictu. The objective of this study is to describe four new species and to present a revised phylogenetic analysis of the Augochlora clade for the placement of these species. The morphological matrix comprised 77 characters and 42 terminals, and resulted in two most parsimonious trees....

Livestock grazing, habitat protection and diversity of bees and wasps in the Central Monte desert
Provedor de dados: 99
Autores: Vázquez,Diego P.; Aschero,Valeria; Stevani,Erica L.
Reserves aim mainly at preventing or mitigating human impacts on natural ecosystems. It is important to assess how well reserves meet this goal. We evaluated whether habitat protection offered by Ñacuñán Biosphere Reserve (Central Monte desert, Argentina) results in detectable changes in habitat structure and the species richness and composition of bees and wasps. We conducted pan trap sampling and flower visitor observations in six pairs of protected and unprotected sites. Our results suggest that thirty fi ve years of cattle exclusion in Ñacuñán have had detectable effects on habitat structure. However, these changes in habitat structure translated only into partial and conflicting effects on hymenopteran richness, and did not have detectable effects on...

Higher-level bee classifications (Hymenoptera, Apoidea, Apidae sensu lato)
Provedor de dados: 104
Autores: 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...

The flowering pattern and the visiting bee species on Sida spp. and Malvastrum coromandelianum (L.) Garcke were studied in a restricted area at the campus of the Universidade Federal de Viçosa, Minas Gerais, Brazil. There were differences among plant species but not among individuals in relation to the flowering time along the day and the time at which the flowers were visited by bees. Melissoptila cnecomala (Moure, 1944) and Cephalurgus anomalus Moure &amp;amp; Oliveira, 1962 were the most frequent visitors. Both species foraged on flowers for nectar and pollen. C. anomalus visited mainly plants with anthesis in the morning and M. cnecomala plants with anthesis in the afternoon. This fact sugests that those species of bees may be showing contrasting...

Provedor de dados: 104
Autores: 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...

Aspectos da biologia de nidificação de Euplusia mussitans (Fabricius) (Hymenoptera, Apidae, Euglossini)
Provedor de dados: 104
Autores: 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 &gt; 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...

Elaiophores: their taxonomic distribution, morphology and functions
Provedor de dados: 39
Autores: 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...

Autores: Pinheiro-Costa,Bruna Karen; Mesquita-Neto,José Neiva; Rego,Juliana Ordones; Schlindwein,Clemens.
ABSTRACT Heteranthery, the presence of different types of stamens in a flower, may reduce the conflict between pollinators and plants by ensuring the resource for the pollinator without drastically affecting the availability of viable male gametes for fertilization, according to the division-of-labor hypothesis. We investigated whether the poricidal anthers of Senna pendula, a buzz-pollinated heterantherous species, present morphological and physiological differences among pollen grains from the three sets of stamens. We compared quantity, ornamentation, size and fecundity of pollen from long, medium and short stamens. The short feeding stamens produced larger but fewer pollen grains than the long pollinating stamens, which produced smaller pollen grains...

Nectar dynamics and reproductive biology of Passiflora actinia Hook. (Passifloraceae) in Araucaria Forest
Provedor de dados: 39
Autores: Varassin,Isabela Galarda; Baggio,Ana Carolina; Guimarães,Paulo César; Prazeres,Luiz Carlos; Cervi,Armando Carlos; Bueno,Raquel de Oliveira.
ABSTRACT Nectar production has an important role in pollinator attraction and successful fruit production in many self-incompatible angiosperm groups. The reproductive biology of Passiflora actinia was studied here and related to nectar dynamics. Passiflora actinia presented a temporal segregation of male and female functions at the beginning of anthesis. Due to the movements of floral verticils, the anthers were positioned in a way that favors pollination two hours before the stigmas reached the same position. The nectary consisted of an epidermis with stomata and a parenchyma rich in starch, which was hydrolyzed during anthesis. The nectary organization is probably associated with the continuous production of nectar during anthesis as well as with the...

Autores: Silva,Alexandre Coletto da; Kinupp,Valdely Ferreira; Absy,Maria Lucia; Kerr,Warwick Estevam.
The Solanaceae family has a wide distribution, mainly in the tropical and subtropical areas of South America. Solanum L. is one of the most important genera of the family with approximately 1,200 species. The objective of this work was to study the floral biology, pollen morphology as well as to investigate the bee visitors of S. stramoniifolium. Preliminary data indicate the presence of one species of stinging bee and four species of stingless bees as visitors to S. stramoniifolium. The pollen of S. stramoniifolium is tricolporate and psilate or without ornamentation. In a word, S. stramoniifolium constitutes a potential source of pollen for different species of bees with and without sting, providing an interesting field for germination studies,...

Pollen-ovule relation in Adesmia tristis and reflections on the seed–ovule ratio by interaction with pollinators in two vertical strata
Provedor de dados: 42
Autores: FERREIRA,NADILSON R.; FRANKE,LUCIA B.; BLOCHTEIN,BETINA.
The vertical distribution of pollinators is an important component in the foraging pattern of plants strata, and it influences the reproductive system (pollen/ovule ratio) and seed/ovule ratio. Niches in two different strata from Adesmia tristis Vogel were evaluated in these aspects. This plant is an endemic shrub from the Campos de Cima da Serra in Southern Brazil. The studies were carried out from January 2010, to January 2011, at Pró-Mata/PUCRS (Catholic University of Rio Grande do Sul) (29°27′-29°35′S and 50°08′-50°15′W), São Francisco de Paula, sate of Rio Grande do Sul, Brazil. Breeding system of A. tristis is mandatory allogamy. The vertical profile in A. tristis has differentiated foraging niches among the most common pollinators. Bees of Megachile...

Provedor de dados: 42
Autores: 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...

Influence of landscape structure on Euglossini composition in open vegetation environments
Provedor de dados: 49
Autores: 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...

Pollinators of Oxypetalum (Asclepiadaceae) in Southeastern Brazil
Provedor de dados: 57
Autores: VIEIRA,M. F.; SHEPHERD,G. J.
Floral visitors of seven species of Oxypetalum were registered in Viçosa, State of Minas Gerais. O. appendiculatum, O. banksii subsp. banksii, O. alpinum var. alpinum and O. pachyglossum are pollinated by wasps, being Polybia ignobilis (Vespidae) a pollinator of these four species. It seems that P. ignobilis promotes interspecific pollinations mainly between O. alpinum var. alpinum and O. pachyglossum, two species with very similar floral morphology. O. jacobinae, O. mexiae and O. subriparium are pollinated by bees. Wasps and bees carry one, two, three or several pollinaria in the mouthparts. O. mexiae, an endemic species in Viçosa, seems to present reproductive limitations, since its flowers are seldom visited.
