“…It was not feasible to measure the real impact of weather changes on the bee activity during the day, which should become a potential target for further researches in the Cerrado area. In general, bees visit flowers mostly at the morning period due to the good climate conditions and floral resources availability (Melo et al 2009, Oliveira et al 2011 and this may explain the male euglossine bee activity at the baits.…”

The orchid bees are a very important group of pollinators distributed in the Neotropics. Although a lot of studies concerning male euglossine bees have been done in this region, few works have so far been carried out in the Cerrado biome. This manuscript has the main objective to present the orchid bee community from a Gallery Forest in the Northeastern Brazilian Cerrado landscape, taking account the species composition, abundance, seasonality and hourly distribution. Male euglossine bees were collected monthly from October 2007 to May 2009, in the Reserva Florestal da Itamacaoca belonging to the Companhia de Água e Esgoto do Maranhão, in Chapadinha municipality, Maranhão State. The scents eucalyptol, eugenol and vanillin were utilized, between 07:00 and 17:00hr, to attract the euglossine males. Cotton balls were dampened with the scents and suspended by a string on tree branches 1.5m above soil level, set 8m from one another. The specimens were captured with entomological nets, killed with ethyl acetate and transported to the laboratory to be identified. A total of 158 individuals and 14 species of bees were recorded. The genus Eulaema was the most representative group of euglossine bees in relation to the total number of the sampled individuals, accounting for 50.6% of bees followed by Euglossa (26.6%), Eufriesea (15.2%) and Exaerete (7.6%). The most frequent species were Eulaema nigrita (27.8%), Eulaema cingulata (19%) and Euglossa cordata (18.3%). Many species typical of forested environments were found in samples, like Euglossa avicula, Euglossa violaceifrons and Eulaema meriana, emphasizing the role played by the Gallery Forests as bridge sites to connect the two great biomes of Amazonia and Atlantic Forest. The occurrence of Exaerete guaykuru represents the second record of this species for the Neotropical region, and both records coming from the Gallery Forest zones. The male euglossine bees were sampled mainly in the dry season, where 62.5% of the individuals were collected in that period. Eufriesea species appeared at the baits only in the wet season. The hourly frequency of bees at scent baits showed a clear preference for the morning period, where 87.9% visited the baits from 07:00 to 12:00hr. The euglossine bee fauna found in the Northeastern Maranhão Cerrado is represented chiefly by species of large geographic distribution and by some forest bee species, where their occurrence is maybe related to to the environmental conditions supported by the

“…A disadvantage of pan traps is that captures are biased towards small insects (Roulston et al 2007;Minckley 2008;Souza and Campos 2008), and larger bees like Bombus, Centris, Svastra, Melissodes, Megachile, and Apis are Knoll and Santos (2012), Nemésio and Silveira (2006), Pearson and Dressler (2009), Nemésio and Morato (2006), Ramírez et al (2010), Melo et al (2009), Janzen et al (1982), Tonhasca et al (2003), Breed et al (1999) Florez et al (2002), Cane (2001), Ricketts (2004) (Cane et al 2000;Roulston et al 2007;Popic et al 2013). Additionally, trap placement can significantly affect bee captures (Droege et al 2010).…”

“…The main advantage of baits is their effectiveness in attracting orchid bees (Tribe: Euglossini) (Janzen et al 1982;Tonhasca Jr. et al 2003;Nemésio and Morato 2006;Nemésio and Silveira 2006;Melo et al 2009;Pearson and Dressler 2009;Ramírez et al 2010;Knoll and Santos 2012), whose males are attracted to the bait odors, and also collect aromatic compounds (Dodson et al 1969). Orchid bee flight is so rapid that they are infrequently collected using other methods (Dressler 1982).…”

“…For instance, there is a large variation in the type and quantity of baits used in either bait traps or lures. The majority of studies reviewed used 2-6 baits per study (Janzen et al 1982;Becker et al 1991;Breed et al 1999;Roubik 2001;Tonhasca Jr. et al 2003;Melo et al 2009;Brosi 2009;Knoll and Santos 2012;Schüepp et al 2012), but two studies used as many as 13-20 (Nemésio and Silveira 2006;Pearson and Dressler 2009). Among the studies reviewed, the most common baits were methyl salicylate, skatole, eugenol, vanillin and cineole.…”

most effective sampling protocols in open tropical systems; conversely, malaise traps, nets and baits may be the most effective in forests. Declining bee populations emphasize the critical need in method standardization and reporting precision. Moreover, we recommend reporting a catchability coefficient, a measure of the interaction between the resource (bee) abundance and catching effort. Melittologists could also consider existing methods, such as occupancy models, to quantify changes in distribution and abundance after modeling heterogeneity in trapping probability, and consider the possibility of developing monitoring frameworks that draw from multiple sources of data.

“…Nevertheless, it is important to point out, particularly in the current study, that although two sampling sites were used, more species could have been collected with increased sampling efforts. Besides, some studies have shown that different Euglossini species can display distinctive pattern of daily activity (Santos & Sofia 2002;Nemésio 2007b;Melo et al 2009). Thus, the restrict period of sampling (9-11 h) used in the current study may have interfered on the number of species collected.…”
