“…CANE et al (2000) compared the use of Moericke traps to entomological nets and collected comparatively few bees in the traps -the opposite of the results obtained by MONSEVIÈIUS (2004), even taking into consideration the different regions of collection. In another survey, STEPHEN & RAO (2005) used yellow and blue Moericke traps and collected 369 bees of 17 genera, the majority being Bombus (62.1%) and Halictidae (23.8%).…”

ABSTRACT. The composition and diversity of bees in an agricultural area in Rio Claro, state of São Paulo, Brazil, were studied from May 2003 to June 2004, using Moericke traps. The collection site, an area with 58.08 hectares, is characterized by grain production and direct planting, with 70% of the surrounding area planted with sugar cane. During the study, 456 bees were collected, distributed among 20 genera, pertaining to the families Andrenidae (4.8%), Apidae (40.8%) and Halictidae (54.4%). Specimens of genera Dialictus (38%) and Diadasia (30%) predominated in this area. The species diversity, assessed using the Shannon and Simpson indices, were H'=1.88 and 1/ D= 4.15, respectively, and the Evenness index was 0.61.

“…We sampled pollinators during the summers of v www.esajournals.org 2007 and 2008 using ultra-violet reflective blue vane traps (Stephen and Rao 2005). Blue vane traps consist of a plastic container (15 cm diameter 3 15 cm high) with a blue polypropylene screw funnel with two 24 3 13 cm semitransparent blue polypropylene cross vanes of 3 mm thickness (SpringStar, Woodinville, WA, USA) (Stephen and Rao 2005).…”

Abstract. Rangelands are significant providers of ecosystem services in agroecosystems world-wide. Yet few studies have investigated how different intensities of livestock grazing impact one important provider of these ecosystem services-native bees. We conducted the first large-scale manipulative study on the effect of a gradient of livestock grazing intensities on native bees in 16 40-ha pastures in the Pacific Northwest Bunchgrass Prairie. Each pasture was exposed to one of four cattle stocking rates for two years and grazing intensity was quantified by measuring utilization. We measured soil and vegetation characteristics related to floral and nesting resources as well as several metrics of the bee community. Increased grazing intensity significantly reduced vegetation structure, soil stability, and herbaceous litter and significantly increased soil compaction and bare ground. Native bees responded with changes in abundance, richness, diversity, and community composition. Responses varied with taxa and time of season. Bumble bees were sensitive to grazing intensity early in the season, showing reduced abundance, diversity, and/or richness with increased intensity, potentially because of altered foraging behavior. In contrast, sweat bees appeared unaffected by grazing. These results show that native bee taxa vary in their sensitivity to livestock grazing practices and suggest that grazing may potentially be a useful tool for managing pollination services in mosaic agroecosystems that include rangelands.

“…According to Cane et al (2001), bowl traps have selective biases, especially for the collection of many large-bodied species (Roulston et al 2007;Minckley 2008; but see Krewenka et al 2001;Stephen & Rao 2005 reports of bumblebee sampling). Also, they have a low performance when compared with hand-netting and malaise traps in dense forested areas (Gonçalves & Brandão 2008;Gonçalves et al 2012).…”

Abstract:In recent years bowl traps have gained attention as a useful method for sampling bees and are now commonly used across the world for this purpose. However, specific questions about the method itself have not yet been tested on different regions of the globe. We present the preliminary results of bowl trapping in a Semidecidual Seasonal forest fragment in southern Brazil, including the test of two different color bowls, two different habitats, and the interaction of these variables in bee species number and composition. We used blue and yellow bowls in the border and in the core trails of the forest fragment. In five sampling days between October to December bowl traps captured 745 specimens of 37 morphospecies, with Halictinae bees being the richest and most abundant group. Non parametrical statistical analyses suggested that different colors of bowl traps influenced bee richness and composition and thus, they should be used together for a more complete sampling. Different trails influenced only the composition, while the interaction with different colors did not have a significant effect. These results, as well as the higher taxonomic composition of the inventoried bees, are similar to other studies reported in the literature.
