A study was conducted in an early second-growth forest aiming at knowing the richness, relative abundance, seasonal distribution, and hourly frequency of euglossine bees, and their association with scent baits. Male bees were attracted to cineole, vanillin, methyl salicylate, and eugenol. The baits were hooked 1.5 m high and 6 m from one another. The specimens were collected from December 1997 to November 1998, once a month, from 7:00 to 17:00 h. A total of 339 male euglossine bees were caughts, accounting for 19 species and four genera. The most common species was E. cordata, making up 69.9% of the individuals, followed by E. truncata (2.3%), E. violaceifrons, and E. smaragdina (2.1%). The most attractive scent was cineole, which baited 87% of the specimens and 73.7% of the species. Vanillin, the second most visited bait, eured 7.6% of the specimens and 26.3% of the species. E. surinamensis was only collected with this bait. Methyl salicylate and eugenol baited combined 2.6% of the...
Euglossine Bees (Hymenoptera: Apidae) of Buriticupu, Amazonia of Maranhão, Brazil1
Acta Amazonica, 1999
Male euglossine bees attracted to cineole, vanillin, methyl salicylate, eugenol and benzyl benzoate, were collected from October 1995 to September 1996, twice a month, between 06.00 and 12.00 hours, at the Companhia Vale do Rio Doce Forest Reserve, Buriticupu-MA. It were sampled 1740 individuals, 37 species and 4 genera. Euglossa was the most abundant genus (23 species), followed by Eufriesea (8), Eulaema (4) and Exaerete (2). The most frequent species were Euglossa pleosticta (33% of the collected individuals), Euglossa truncata (12,7%), Euglossa avicula (6,3%), Eufriesea superba (5,2%), Euglossa fimbriata (4,8%) Euglossa violaceifrons (4,4%), Eulaema nigrita (4,1%), Euglossa cordata (4,0%), Eulaema meriana (3,4%). Cineole attracted 66% of males and 70% of species, vanillin (20%; 59%), methyl salicylate (7,4%; 54%), eugenol (5,6%; 44%) and benzyl benzoate (0,7%; 10,8%). The highest abundance of individuals (78,3%) and species (34) occurred in the rainy season (January-June). The sp...

The present catalogue lists the bee types (Hymenoptera, Apidae s.l.) deposited in the Museu de Zoologia, Universidade de São Paulo, Brazil (MZSP). The Hymenoptera collection of the MZSP is one of the most important collections for the Brazilian and Neotropical faunas, holding relatively large number of types and represented taxa. The Apidae collection includes a total of 473 type-specimens (101 holotypes, 30 lectotypes, 190 paratypes, 34 paralectotypes, and 119 syntypes) that represent 257 species currently classified in 88 genera, 22 tribes, and five subfamilies (Andreninae, Apinae, Colletinae, Halictinae, and Megachilinae). Label data and additional information from the MZSP registers, literature sources, and taxonomic remarks are given, including high-resolution photographs of holotypes and lectotypes available through links to Specimage (image database of The Ohio State University).
Euglossine bees (Apidae) in Atlantic forest areas of São
We investigated the diversity of euglossine bees in ten areas of Atlantic Forest Domain in São Paulo State, Brazil. Bees were collected with odor baits for 2 years, from March 2007 to March 2009. From a standardized effort during the first year of sampling, we compare the four areas using indexes of diversity, evenness, and similarity of euglossine communities. In the second year, we added six new places for presenting a general overview on the Atlantic forest in São Paulo. A total of 2,395 individuals of 23 species were recorded in the study areas. Ilhabela had the highest number of species (19) and individuals (1,260). The most attractive odor bait was eucalyptol, which attracted 16 species and 58 % of all individuals. Euglossa cordata (Linnaeus 1958) was the most abundant species, representing 50 % of the individuals sampled; apparently, populations of this species are more abundant at low altitudes, as for example on islands and on the coast. The results also suggest a difference in richness among altitudes, since coastal areas (where the climatic variation are milder) had more species. The present study advances knowledge on the occurrence of euglossine bees in the Atlantic Forest and fills the lack of a systematic study of these bees of coastal areas in São Paulo State. orchid bees / pollinators / diversity / deforestation / conservation
Orchid Bees (Hymenoptera: Apidae: Euglossini) in Seasonally Dry Tropical Forest (Caatinga) in Brazil
Sociobiology, 2018
Euglossini bees are important Neotropical pollinators, but there is a lack in the knowledge about this fauna in dry tropical environments. The aims of this study were to evaluate the richness and abundance of euglossine bees in two fragments of seasonally dry tropical forest (Caatinga), as well as to assess the distribution of euglossine species richness in the Caatinga environment. Males were collected along 12 consecutive months, using traps with aromatic baits. The species richness (S=5) was lower than in rainforests and savannas. Euglossa cordata (L.) was the dominant species in the assemblage, representing 70% of the individuals. The highest abundance occurred in the rainy season. Euglossini fauna presents low local species richness in Caatinga areas, however the beta diversity is higher, since assemblages in different habitats have differences in species composition.
