    Abstract: Abstract— Conchocarpus is the largest genus of Galipeinae (tribe Galipeeae), which is the most diverse group of Neotropical Rutaceae, with ca. 50 species. Recent phylogenetic analyses support a recircumscription of Conchocarpus to accommodate the species of Almeidea , a taxon from the Brazilian Atlantic Rainforest and Bolivia whose synapomorphy is the possession of pantocolporate pollen grains. Four species are recognized here: C. albiflorus , C. coeruleus , C. hendrixii , and C. ruber . A taxonomic revision of this group of four species of Conchocarpus is provided, with updates of their nomenclature, morphology, circumscription, geographic distribution, and preliminary conservation status, as well as a key to the species and illustrations. Conchocarpus limae and C. lilacinus are consigned to the synonymy of C. ruber .

    Abstract: The study aimed to describe bionomic aspects of Tetrapedia diversipes Klug, 1810 in order to allow the conservation or breeding of these bees. The nesting biology was studied using trap nests made with cardboard-paper tubes and plastic straws during the period between December 2014 and September 2015, in the Bee Unit of the Federal University of Ceará, Brazil. A total of 135 nests were obtained with 593 brood cells, from which emerged 448 adults and individuals of two parasitic species. The proportion of females (n = 297) was higher than that of males (n = 151) resulting in a sex ratio of 1.97:1. The total mortality in the nests was 24.45% and the majority of deaths recorded occurred at the pupal stage (33.1%). During their reproductive life, females of this bee species were able to construct up to 16 brood cells. The trap-nests removal and transfer to the laboratory shortly after finished by the bees reduced the attack of natural enemies.

    Abstract: Interações planta-polinizadores são relações que envolvem na maioria das vezes ganhos para ambos os organismos. Os polinizadores coletam recursos alimentares (principalmente pólen e néctar), e suas atividades favorecem a reprodução das plantas. Neste estudo, por meio de observação indireta, foi avaliado o uso das plantas para a coleta de recursos florais por Bombus (Thoracobombus) morio Swederus (1787) e Bombus (Thoracobombus) pauloensis Franklin (1913), por meio da análise palinológica de cargas de pólen corbicular de indivíduos amostrados enquanto forrageavam em flores. O estudo possibilitou a identificação das espécies vegetais visitadas e também polinizadas por B. morio e B. pauloensis durante o forrageio. As coletas das abelhas nas flores foram feitas durante a primavera e verão de 2017 a 2018. Com a análise polínica, foi possível identificar a origem botânica dos recursos florais e verificado que na maioria das vezes os grãos de pólen predominantes não condiziam com a espécie de planta na qual o Bombus foi amostrado. A espécie B. morio foi amostrada em flores de 10 espécies de plantas e por meio da análise palinológica, identificado 52 tipos polínicos, enquanto que na espécie B. pauloensis, amostrada em flores de seis espécies de plantas, foram identificados 38 tipos polínicos. O recurso floral mais visitado por B. morio foi Jacaranda brasiliana e por B. pauloensis, Senna macranthera, no entanto, o tipo polínico encontrado em maior quantidade nas amostras de pólen para ambas as espécies foi de Solanum sp., permitindo inferir que essa planta é a mais atrativa. No total foram identificadas 11 espécies de plantas visitadas e 55 tipos polínicos associados à essas duas espécies de Bombus no Rio Grande do Sul, representados principalmente por plantas nativas (98%).

    Abstract: Several factors can influence the distribution of floral resources and pollination systems in ecosystems, such as climate, altitude, geographic region, fragmentation of natural areas and differences in floristic composition along the vertical stratification. This study aimed to evaluate the distribution of the vertical stratification of biotic pollination systems in cerrado (sensu stricto) fragments in the Triângulo Mineiro. There was no significant difference (χ²0.05,9=14.17; P = 0.12) in total plant species richness among fragments, nor in the species richness of each layer (trees, shrubs, herbs and lianas) and the shrub layer was the best represented. Likewise, there was no significant difference between fragments for the systems of pollination (χ²0.05,21 =13.80; P = 0.8778). Pollination by bees was the most common, corresponding to 85% of species in each fragment. In relative terms, plants pollinated by bees were dominant in all strata, reaching 100% for the lianas in fragments 1, 3 and 4 and for the herbs in fragments 1 and 4. In this study, based on floristic composition and distribution of biotic pollination systems in the vertical stratification, we could define a vertical mosaic in the cerrado studied, which has implications for the sustainability of communities in the cerrado, as well as the horizontal mosaic of vegetation types.

    Abstract: Abstract Flower visitors are animals that generally seek resources in flowers for themselves or their offspring. Sometimes the same plant may receive a broad spectrum of visitors, such as nectar species. However not all floral visitors complete pollination. To be an effective pollinator is necessary to fulfill some requirements, such as: contact with the anther and stigma, enough frequency of visits, fidelity to the plant, and the realization of a suitable route of visitation. In many works on the structure of communities and especially of food webs (animal-plant), the authors adopt the term pollinator for each and every flower visitor categorizing them with the same role and function for the plant. In this work we report cases of floral visitors who are legitimate and effective pollinators of which the plant depends on its service for the production of fruits and seeds, distinguishing them from those visitors who do not pollinate, or are not sure to do so. Thus, it is expected to illustrate the differences, giving due importance and the correct weight for the many visitors. We used bees as a model, but the idea can be extrapolated to any other pollinator group.

    Abstract: About 85% of pollinating bees are solitary, but few are used for agricultural pollination. The Anthidiini tribe looks very promising in Brazil, in the light of ecosystem utility, but  it is still a species with poorly scientific research[EdM1] . To fill this gap studies on the bionomics of this species may collaborate on future studies on use of Epanthidium tigrinum as pollinator. Presented research results aims to describe the bionomy and the biological cycle of the bee E. tigrinum (SCHROTTKY, 1905) in pre-existing cavities. Conventional trap-nests inserted in wooden blocks were placed in covered spaces and daily observations of spontaneous nesting as well as individua lly tagged bees and nests incubated in B.O.D. were carried out during 11 months in Fortaleza-CE. The results showed that the competition with other species of bees for the pre-existing cavities and the lack of food resources or nest building materials are limiting factors for the establishment of E. tigrinum populations. However, once these problems were remedied, the bees showed multivoltine behavior, nesting throughout the experimental period. Data from 16 nests studied showed that bee foraging began on average at 7:50 a.m., foragers collected pollen in the morning and resin in the afternoon, took on average 15 days to complete a nest and there was a negative correlation with the temperature for the number of nests and for the number of cells constructed. The offspring took 43 days for the emergency, presented sexual ratio of 1.2: 1 (n = 66 emerged bees) and a mortality rate of 18.5%. The number of nests constructed per female ranged from 1 to 4 with an average size of 7.97 mm. It is concluded that E. tigrinum shows potential to rational rearing in trap nests aiming crop pollination. [EdM1]

    Abstract: Cities provide resources for animal species that live within them or inhabit their surroundings. This has motivated an increase in ecological studies of urban areas, including the interactions between plants and pollinators. From March 2010 to February 2011, the flowering plants present in the study area, located at the Universidade de São Paulo, Ribeirão Preto, were sampled to evaluate how floral sources were distributed throughout the year. Concurrently, worker bees with pollen loads were collected from four colonies of Frieseomelitta varia (Lepeletier, 1836) to identify the sources used by bees. Despite an increase in plant species abundance in July, plants were in bloom year-round and consequently, the production and supply of floral resources were continuous. The workers collected resources from 77 plant species, but only three were extensively exploited. Delonix regia (Leguminosae), Poincianella pluviosa (Leguminosae) and Ceiba speciosa (Malvaceae) accounted for 42% of total pollen grains quantified during the year, showing that F. varia intensify pollen collection at few sources at spatiotemporal scale. This study emphasizes the importance of native urban flora to maintain F. varia and other bee species. The list of plants presented in this study can be used in the design and planning of urban areas.

    Abstract: The flora of mountain formations in the Caatinga biome is composed predominantly by semi-deciduous species with representatives of both Atlantic and Amazon forest. Information on the potential for bee pollen production of these species is limited. In this study we evaluated the potential of production, the temporal variation, the botanical origin and the nutritional value of bee pollen produced in a seasonal semideciduous forest in northeastern Brazil. We identified a total of 252 flowering plant species throughout the year. The diet of Apis mellifera consisted of 74 pollen types distributed in 58 genera and 27 families. We identified two production peaks of bee pollen, the highest occurring in the rainy season. Nutritional value considering crude protein, carbohydrates, lipids and mineral matter changed over the study period, with influence of rainfall on the dry matter level. Some taxonomic groups of plants showed a strong relationship with nutrients, suggesting that although the diet of A. mellifera is broadly diversified, this species devoted most of its pollen foraging effort on the genus Mimosa and the palm tree species of Attalea speciosa. The results show that the seasonal semideciduous forest of the mountain range in the Northeast Brazil presents plant species: Mimosa caesalpiniifolia, Baccharis trinervis, Mimosa tenuiflora Myracrodruom urundeuva, Cecropia pachystachya, Attalea speciosa, with high nutritional level and potential for the pollen production.

    Abstract: This study tested three types of Solid-Phase Microextraction fibers in developing a method to extract volatile organic compounds present in the diet of immature Centris analis. Samples were placed in glass vials with metal lids and added with 3g NaCl and 8 ml deionized water. Extraction and characterization were carried out using a Headspace – Solid Phase Microextraction (HS-SPME) with Gas Chromatography – Mass Spectrometry, and the three types of fibers were polydimethylsiloxane (PDMS), divinylbenzene/ carboxen/ polydimethylsiloxane (DVB/CAR/PDMS) and carboxen/ polydimethylsiloxane (CAR/PDMS). Each type of fiber was exposed to volatiles for 30 min and analyzed in a chromatograph Agilent GC-MS equipped with a quadrupole detector (MSD 5977A), containing a HP-5MS (30 m x 0.25 mm x 0.25 µm) column and Helium as the carrier gas (1 ml.min-1). The CAR / PDMS fiber favored the extraction of volatile compounds to semi-volatile compounds, followed by DVB / CAR / PDMS, while PDMS presented a lower number of extracted compounds, which can be attributed to its apolar nature. The volatile compounds identified in the diet included alcohols, aldehydes, esters, ketones, and terpenes. The SPME technique has proven effective in the extraction of volatile organic compounds from immature of Centris analis diet, being the CAR/PDMS the most suitable fiber for this.
