Bee assemblage in habitats associated with Brassica napus L.

Rev. Bras. entomol.

Halinski,Rosana; Dorneles,Andressa Linhares; Blochtein,Betina.

ABSTRACTAssessments in agricultural crops indicate that alterations in the landscape adjacent to the crops can result in reduced productivity due to loss or low abundance of pollinating agents. In the canola crop, production is partially dependent on insect pollination. Therefore, knowledge of the faunal diversity within and near crop fields is key for the management of these insects and consequently for the increase in productivity. This study aimed to determine and compare the diversity of bees in habitats associated with canola fields in southern Brazil. Bees were captured in four agricultural areas using pan traps in three habitat classes: (1) flowering canola crop, (2) forest remnant, and (3) grassland vegetation. The highest abundance of bees was...

ABSTRACT A pilot experiment was undertaken in order to examine high oil populations of maize (Zea mays L.) to be used as pollinators in TopCross blends with commercial ZP341 standard hybrid. Five high oil populations (HOPs) from the Maize Research Institute (MRI) gene bank were chosen for this research, according to their high grain oil content, synchrony between silking of ZP341 and anthesis of the populations and good agronomic performances in 2012. Selfing of ZP341 and HOPs, as well as crosses of ZP341 cmsS sterile × HOPs were carried out in 2013. Oil content, fatty acid composition, protein and tryptophan content, and physical characteristics of the obtained kernels were measured. Four HOPs showed significant positive influence on the oil content in...

O objetivo deste trabalho foi estudar a fenologia, biologia reprodutiva e visitantes florais de Sideroxylon obtusifolium em área de caatinga. O estudo foi realizado de outubro de 2003 a setembro de 2005, em populações naturais de S. obtusifolium, na Reserva Legal do Projeto Salitre, em Juazeiro, BA. Os dados fenológicos indicaram que as fenofases vegetativas (brotação e senescência foliar) ocorreram ao longo do ano, enquanto a floração e frutificação foram registradas na estação seca e das chuvas, respectivamente. As flores são hermafroditas, de coloração creme, exalam odor, secretam pequena quantidade de néctar (< 1 ?l) e apresentam antese diurna e dicogamia protogínica. Entre os visitantes florais, foram registradas abelhas, vespas, moscas e...

Blueberry (Vaccinium ashei) is a relatively new crop in cultivation under Southern Brazil conditions. The first collection introduced in the area was formed by rabbiteye cultivars which need insect pollinators and also pollinizers. The aim of this work was to observe if there were differences between pollinizers on fruit quality of the commercial cultivar and also to observe the most effective and frequent insect pollinators, under natural conditions. It was concluded that pollen source has an effect on quality of blueberry fruits. Bumblebees are the most efficient pollinators; however the species found in southern Brazil are different from the ones mentioned in the U.S. literature.

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...

Due to their importance as pollinators of many plant species, this study aimed to know the nest density, spatial distribution, and nesting substrates used by Xylocopa species in the Caatinga, a xerophilous vegetation f Northeastern Brazil. Three areas of Caatinga in the surroundings of passion fruit crops were sampled. The bee species found in these areas were Xylocopa grisescens Lepeletier and Xylocopa frontalis (Olivier). All nests were in Commiphora leptophloeos (Burseraceae) trees (n=113). Phytosociological analysis showed that this tree species presented the highest absolute density (212.5 individuals/ha) and index of importance value (52.7). The distribution pattern of the C. leptophloeos was aggregated. The nests were located in dead and dried...

Abstract: The aim of this study was to evaluate the diversity of Meliponini and anothers Apiformes (Apidae sensu lato) from a Cerrado fragment and its surrounding. Malaise traps were installed in a pasture near a fragment of Cerrado and its surrounding, from October to December 2010. Samples were collected at seven-day intervals and preserved in Dietrich solution. The apiforms specimens from each sample were separated in morphospecies and sent to identification. The tribe Meliponini was the most abundant in open areas of pasture than in the Cerrado fragment. The Meliponini species present were Trigona gr. fulviventris, Paratrigona lineata, Trigona recursa, Partamona sp, Trigona spinipes, Trigona gr. hyalinata, Trigona gr. fulviventris, Tetragonisca...

This paper surveys the literature on pollinator declines and related concerns regarding global food security. Methods for valuing the economic risks associated with pollinator declines are also reviewed. A computable general equilibrium (CGE) approach is introduced to assess the effects of a global catastrophic loss of pollinators. There appears to be evidence supporting a trend towards future pollinator shortages in the United States and other regions of the world. Results from the CGE model show economic risks to both direct crop sectors and indirect non-crop sectors in the economy, with some amount of regional heterogeneity.

Efeito da polinização por abelhas e outros insetos na produção de sementes de cebola.

WITTER, S.; BLOCHTEIN, B..

A deficiência de polinização tem sido apontada como uma das causas da baixa produção de sementes na cultura da cebola. O objetivo deste trabalho foi avaliar a relação da presença de abelhas e outros insetos em flores de duas cultivares de cebola, Allium cepa L. (Alliaceae), com a produção de sementes. Foram registradas a diversidade e a freqüência de insetos nas flores de cebola e o efeito polinizador foi testado. O comportamento de Apis mellifera foi observado diretamente nas flores e a fidelidade verificada a partir do pólen nas corbículas. Representantes de Hymenoptera e Diptera foram os visitantes florais mais abundantes. Houve correlação entre a freqüência de A. mellifera com número de umbelas com flores, em ambas cultivares, e de outros insetos em...

ABSTRACT The blueberry (Vaccinium ashei Reade, Ericaceae) is a small fruit with great growth potential in Brazil. This research was developed in order to identify the insects found on associated to the different phenological stages of blueberry in order to implement the integrated pest management for this crop. Insect samples were collected from three orchards, in the region of Pelotas, RS, from January 2010 to June 2012. The data were analyzed based on the composition and abundance of the collected insects. In all three sites, 2,354 insects were studied and the majority belonged to Hymenoptera (72%), Coleoptera (16%), Hemiptera (6%) and Diptera (4%). Forty-one families were identified with 59% of the listed insects belonging to the Apidae family,...

This study aimed to investigate the floral biology and pollination requirements of sesame (Sesamum indicum L.), cultivar CNPA G2. The study was carried out at Barbalha, State of Ceará, and consisted of two phases: floral biology and pollination requirements. Flowers were observed as for time of anthesis, lifespan and stigma receptivity, and were applied the following pollination treatments: open pollination, hand cross-pollination, hand self-pollination, pollination restricted with tulle bags and pollination restricted with paper bags. Significant differences (p < 0.05) were detected between treatments for the number of fruits harvested 30 days after pollination. It was shown that the sesame plant presents a mixed-pollination system, because it can...
