“…Nada se sabe sobre os mecanismos que promovem o início do comportamento de coleta nos machos de Euglossini, mas pode-se pensar em estímulos ambientais. Existem evidências para isso, pois machos nascidos e mantidos em cativeiro não coletam substâncias aromáticas oferecidas a eles, mesmo as fortemente atrativas a seus co-específicos vivendo em condições naturais (PERUQUETTI & CAMPOS 1997;PERUQUETTI 1998); 2) estes compostos estariam ausentes dos materiais utilizados pelas fêmeas para a construção do ninho. Essa observação estaria de acordo com a hipótese de LUNAU (1992) para explicar a evolução do comportamento de coleta nos machos de Euglossini.…”

ABSTRACT. Eugl ossine bees (Apidae) frem Atlantic Forest sites: abundance, richness, and bi ological aspects. Co llection data of Euglossinae males from Parque Estadual do Rio Doce (PERD) and Viçosa, both areas w ith remnants of Atlantic Rain Forest (Mata Atlântica) in Minas Gerais state, Brazil are presented. Comparisons made among three fragments with different sizes and states of di sturbance fi'om Viçosa showed difterences in abundance of most common spec ies and apparently, Eu/aema nigrita Lepeletir, 1841 can be an useful indicator of disturbed sites . Some populations of euglossine bees seems to be restrict to a forest fragment, there being few or no tlow of individuais OI' species of one fi'agment to another, even when they are only I km apal1. 15 species of euglossines were sampled in PERD, and the most abundant was Eu/aema cingu/ata (Fabricius, 1804). At Viçosa, 10 species were samp led, E. nigrita was the predominant one. Methyl sali cylate attracted no males at both sites, in spite of large numbers of species and individuais sampled using this bait in other regions. The majority ofspecies and indi viduais were collected in the rainy season. Only 0,58% ofsampled males carried orchid pollinia (Cataselum Richard, Cycnoches Lindley and Coryanthes Hook) on their bodies. Emergence data of [our species 01' Eug/ossa Latreille, 1802 reared from trap nests suggest lhat sex ralio in Euglossini is not a constant w ithin the lribe. A li sl of 57 eugloss ine spec ies now known to occur in Mata Atlântica are oftered. KEY WORDS. Apidae, Euglossini, Atlantic Forest, conservation, bioindicator Há 35 anos machos de Euglossini vêm sendo coletados com auxílio de iscas contendo compostos aromáticos similares aos encontrados em flores de algumas Orchidaceae e de outras plantas e em alguns fungos. Foi LOPES (1963) o primeiro a verificar que machos dessas abelhas podiam ser atraídos e capturados utilizando-se armadi lhas contendo compostos aromáticos como iscas. Isto, associado a sua grande diversificação ecológica e taxonômica, abundância e importância em alguns ecossistemas, faz desses insetos candidatos a indicadores das qualidades ambientais de áreas naturais ou de conservação (BROWN 1991).

“…Duas hipóteses são sugeridas para o fato de alguns compostos considerados bons atrativos não atraírem Euglossina em determinados locais: (1) estes compostos aromáticos não estariam presentes em nenhum recurso natural utilizado pelos machos para obtenção de fragância, não sendo assim reconhecidos (PERUQUETTI & CAMPOS, 1997;PERUQUETTI, 1998); ou (2) estes compostos estariam ausentes nos materiais utilizados pelas fêmeas para a construção do ninho (PERUQUETTI et al, 1999).…”

ABSTRACT. Euglossina bees (Hymenoptera, Apidae) collected in an eucalyptus monoculture surounded by Cerrado, Urbano Santos, MA, Brazil. Males of Euglossina bees were collected in benzil benzoate, eucaliptol, eugenol, methyl salicylate and vanillin scent baits in an eucalyptus monoculture surrounded by cerrado, located in the municipality of Urbano Santos, Maranhão. The collections were carried out monthly, from April 2001 to April 2002, between 8 a.m. and 4 p.m., totaling 96 hours of sampling, resulting in 58 individuals of 3 genera and 10 species. Euglossa Latreille, 1802 was the most abundant genus, followed by Eufriesea Cockerell, 1909 and Eulaema Lepeletier, 1841. The most frequent species were Euglossa cordata (Linnaeus, 1758), Euglossa gaianii Dressler, 1982 and Euglossa modestior (Dressler, 1982). Eucaliptol was the most attractive chemical bait. The highest frequencies of visits were in the morning and the highest abundance in September, in the drought period, and December, in the rainy period.

“…Euglossa have nest architecture in the subgenera Euglossa s.s. and Glossura similar to Eufriesea, with brood cell divisions and closing plugs of resins only (Garófalo et al, 1998;Peruquetti, 1998;. Entrance diameters varied from 11-22 mm.…”

“…Entrance diameters varied from 11-22 mm. Brood cells may be linear (vertical or horizontal) or clustered (Garófalo et al, 1998;Peruquetti, 1998;, and the usually oval cells vary from 4-14 per nest (Garófalo et al, 1998;Peruquetti, 1998;. Preliminary plugs were not mentioned, while a distal empty space is typical (Parra-H & Nates-Parra, 2009).…”

“…Twenty genera are recognized in this tribe, four of which are found in Mexico and Central America (Ashmeadiella, Atoposmia, Heriades and Osmia; Michener, 2007). Osmiini nest in the soil and in existing cavities (Rozen et al, 2010;Rozen-Jr. & Praz, 2016), using a variety of materials, including petals, mud, pebbles and resins (Praz et al, 2008). Osmiini from the New World tend to nest aboveground more than those from the Old World (Praz et al, 2008), however, the group lacks phylogenetic consensus which is necessary for a proper reconstruction of nesting behavior (Praz et al, 2008;Gonzalez et al, 2012).…”

What do we know about Neotropical trap‑nesting bees? Synopsis about their nest biology and taxonomy

Cavity-nesting bees are enigmatic because they are difficult to observe in the wild, hence trap-nests (man-made cavities) provide the means by which these bees may be studied. Trap-nests is an efficient methodology to study these bees and are common worldwide. These traps have been used for a variety of reasons, including inventories, to examine pollen load, to study habitat disturbance, and bee conservation. However Neotropical trap-nesting bees’ taxonomy and biology are still poorly known and here we provide a review about these subjects. We searched for trap-nest bee studies in the Neotropical Region using Google Scholar and ISI Web of Science at any time in the past to December 2017. We found 109 independent studies, most of which were from Brazil (87 studies), followed by Argentina (10 studies), and other countries had fewer than five studies each. A total of 140 species, 24 genera, 10 tribes and three subfamilies were reported in trap-nests. Nest architecture was described for only 49 species. Taxonomy is only well-known for 14 genera, somewhat known for seven and is essentially unavailable for three genera. Construction material, closing plug and cell shape are similar among species in the same tribes and genera. Vestibular and intercalary cells, and the preliminary plug are variable, even at the specific level. Apinae is the most studied group with available data for all genera recorded in trap-nests. Colletinae is the least-studied group and nothing is known for their nesting biology. Megachilinae is intermediate, with some studies of taxonomy and nesting. We suggest that further trap-nest studies should provide more detailed information on nest architecture and construction materials, including explicit mention of structures that are absent. All Neotropical bees need more taxonomic studies, but some, such as Hylaeus and Megachile, require more attention since Hylaeus is essentially unknown and Megachile is very common on trap-nests.
