Composition and diversity of bees (Hymenoptera) attracted by Moericke traps in an agricultural area in Rio Claro, state of São Paulo, Brasil

Abstract

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.

Preliminary results of bowl trapping bees (Hymenoptera, Apoidea) in a southern Brazil forest fragment

“…The presence of representatives of Andreninae and Apinae and the absence of Colletinae and Megachilinae (groups previously known for the study site by the authors) were also a pattern recovered in other Brazilian localities using bowl traps (Krug & Alves-dos-Santos 2008;Souza & Campos 2008), but see Aisen & Feinsinger (1994) and Droege et al (2010) for studies where these groups were sampled.. The introduced honey bee (Apis mellifera Linnaeus, 1758), a species attracted to bowls (Krug & Alves-dos-Santos 2008;Droege et al 2010), were not sampled in this study, but its presence in the study area was confirmed by personal observation and hand-netting.…”

“…Aizen & Feinsinger (1994) showed a greater richness of Apinae for Argentinean Chaco, but Augochlora and Dialictus morphospecies were not sorted in their study. For Brazil, such abundance of Halictinae has been previously recorded, including the higher richness of Dialictus (Krug & Alves-dos-Santos 2008;Souza & Campos 2008) confirming the prevalence of the group. Dialictus is a group also strongly sampled by netting in southern Brazil, as reported by Krug & Alves-dos-Santos (2008), Gonçalves et al (2009), Sakagami et al (1967.…”

“…This method has recently gained increased attention among melittologists, especially after the contribution of Droege et al (2010). Published studies from Brazil reached to different conclusions about the performance of this sampling method, some reporting efficient captures (Krug & Alves-Dos-Santos 2008;Souza & Campos 2008), but others reporting very poor performances (Gonçalves & Brandão 2008;Gonçalves et al 2012). Currently, at least 11 studies using pan traps have been carried out in different regions of the country (as reported by Simões et al 2012).…”

Abelhas (Hymenoptera, Apidae sensu lato) do Estado de Mato Grosso do Sul, Brasil

“…Dentre os levantamentos feitos no Brasil, apenas recentemente as bandejas amarelas foram empregadas em inventários e apontam uma eficiência relativamente maior em comparação à captura em flores (Krug & Alves-dos-Santos, 2008;Souza & Campos, 2008). Essa metodologia é muito utilizada na Costa Rica e, na América do Norte, faz parte das técnicas tradicionais de amostragem em trabalhos faunísticos de Hymenoptera (Darling & Packer, 1988;Hanson & Gauld, 1995 Zanella, 2002 6 X Lophopedia minor Aguiar, 2009 6 X Lophopedia nigrispinis (Vachal, 1909) 6 X Lophopedia pygmaea (Schrottky, 1902) I, III, V 1, 2, 6 MUBIO X Lophopedia sp.…”

Effectiveness of two sampling methods used for collecting Ichneumonidae (Hymenoptera) in the Cabañeros National Park (Spain)

“…As a consequence, they are the most commonly used traps in studies of Ichneumonidae (Anento & Selfa, 1997a, b;Kumagai & Graf, 2000Skillen et al, 2000;Sääksjärvi et al, 2004). The Moericke yellow traps are commonly used for sampling aphids (Moericke, 1950(Moericke, , 1951, flies or bees (Duviar & Pollet, 1973;Monsevi ius, 2004;Laubertie et al, 2006;Souza & Campos, 2008), but, although less effective than the Malaise traps, are also used for collecting Ichneumonidae as well (Sawoniewicz, 1986(Sawoniewicz, , 1995Hilszcza ski, 1998;Onody & Penteado-Dias, 2002) because they collect species not caught by Malaise traps (Delfín & Burgos, 2000;Leirana-Alcocer & González-Moreno, 2007).…”
