“…The number of published studies showing the species composition of orchid bee fauna in the states of Pará and Maranhão is still less significant (Brito and Rêgo, 2001;Silva and Rebêlo, 1999) and most of them are small inventories carried out in very specific localities (Maués et al, 2012;Moura et al, 2011;Santos et al, 2011;Pereira et al, 2014;Taniguchi et al, 2012). Although recent studies have been taken on the state of Pará, addressing the effects of land use, isolation and climate changes on orchid bee assemblages, they are concentrated in the southeast and western of the state of Pará, outside of the BEC domain (Antonini et al, 2017;Brito et al, 2017;Solar et al, 2016), and ours is the first to addresses the rescue of historical records of these bees in the area.…”

The distribution of most species occurs in delimited regions with unique characteristics called "centers of endemism". In Eastern Amazon is located the Belém Endemism Center (BEC), one of the most intensely deforested in Brazilian Amazon. Here, we show information about orchid bee assemblages based on historical records from entomological collections. For each species, we calculated occurrence frequency and dominance, and we classified them in 3 statuses: common, intermediate or rare species. Curves of observed and estimated richness were built, based on Jackknife estimator. We found 1,257 specimens from 56 species, constituting records from 1917 to 2009, and one species is a new record for BEC. Higher number of specimens and species was concentrated in a few locations and surveys increased from the 70's. The results suggest a high richness of orchid bees in the BEC, although this scenario is far from what is expected for the entire area. The high occurrence of rare species may be related to their low representativeness in the collections, and the proximity between the areas had favored samplings. Even so, the species list and the conservation status presented here may be useful information in studies comparing past and current orchid bee fauna, and, allied to data on bees' responses to land use changes occurred in BEC over the years, can fit as a basis for defining priority areas for conservation.

“…Furthermore, Malaise traps may not be the most appropriate sampling method for bees. Although showed as highly effective for parasitoids (Mazón and Bordera 2008) and aculeates in general (Volpato et al 2020), with some reported bias either towards males (Aguiar and Santos 2010) or females (Mazón et al 2020), scent-baited traps or entomological nets seem to work better for bees (Santos Júnior et al 2014;Ferronato et al 2018;Alvarenga et al 2020). Other sampling methods should be used to complement Malaise traps, especially when time for field work is brief (McGravy et al 2016;Saunders and Ward 2018).…”

Ecosystems under ecological restoration should be monitored in order to investigate if the ecosystem is being functionally recovered, especially in highly vulnerable biodiversity hotspots like Andean forests. Here we sampled Hymenoptera families in four Andean forest reserves above 1800 masl from Southern Ecuador, in three conservation levels in each forest: low (degraded), medium (10–15 years of recovery) and high (well-conserved forest). All Hymenoptera families were classified into four functional groups: predators, herbivores, pollinators and parasitoids. A total of 32 hymenopteran families were collected, with parasitoids clearly dominating in the samples. Family assemblages were not statistically different, neither in abundance nor family richness. Assemblages were more similar between them in the high and medium areas than in low conservation areas, where assemblages were very variable and showed a higher functional diversity in two of the reserves. The low presence of pollinators may be due to the high humidity during the sampling and the sampling method. Although some results are promising for the restoring trajectory, especially for parasitoids, we should keep in mind that this is at family level, so it would be interesting to know if these patterns persist at lower taxonomic levels.

“…De forma geral, vanilina e eugenol têm se mostrado bastante atrativas em diversos estudos (PERUQUETTI et al, 1999;OLIVEIRA JUNIOR et al, 2015;SANTOS JÚNIOR et al, 2014). No presente trabalho, vanilina foi a isca odorífera com mais preferência, atraindo maior número em abundância de indivíduos, seguida por eugenol que atraiu maior número em riqueza de espécies, e a menos atrativa foi geraniol.…”

“…Alguns estudos também obtiveram resultados semelhantes em relação à maior número de espécies atraídas pela isca eugenol e espécimes por vanilina, ou vice-versa. Santos Júnior et al (2014), também observaram resultado semelhante, onde eugenol atraiu maior número de espécies. Ferreira et al (2011), observou em seu estudo resultado oposto, onde as armadilhas com eugenol coletaram maior número de espécimes, enquanto vanilina atraiu maior número de espécies.…”

As abelhas da tribo Euglossini (Hymenoptera: Apidae) são extremamente importantes na polinização das florestas neotropicais e por serem sensíveis a mudanças em seu habitat, são consideradas excelentes bioindicadores de qualidade ambiental. Nesse contexto, o presente estudo objetivou (i) comparar a riqueza de espécies e abundância de indivíduos de Euglossini entre fragmento de floresta, pastagem e plantação de soja; (ii) identificar a preferência pelas iscas odoríferas; e (iii) avaliar o efeito de borda sobre a riqueza de espécies e abundância de indivíduos. O estudo foi realizado no município de Mojuí dos Campos, Pará, Brasil, em três áreas: fragmento de floresta, pastagem e plantação de soja. Utilizou-se seis iscas odoríferas para atrair os machos: eugenol, eucaliptol, vanilina, benzoato de benzila, cinamato de metila e geraniol. Foram coletados 1668 indivíduos distribuídos em quatro gêneros e 11 espécies. Existe diferença significativa na abundância de Euglossini entre os ambientes (F(2,24) = 4,1007; p = 0,029), a maior abundância ocorreu na área de pastagem (866-52%). Houve diferença significativa tanto na abundância (F(5, 156) = 15,811; p < 0,001) quanto na riqueza de espécies (F(5, 156) = 70,039; p < 0,001) de Euglossini entre as iscas. Vanilina mostrou-se a isca mais atrativa e geraniol a menos atrativa. Não há diferença significativa na abundância (F(2, 24) = 1,8505; p = 0,178) e riqueza de espécies de Euglossini (F(2, 24) = 0,299; p = 0,744) entre os transectos borda, intermediário e centro, o que pode estar relacionado com a proximidade entre as áreas e a capacidade das abelhas de voar longas distâncias. Outro fator que pode influenciar nesse resultado, é a capacidade de dispersão dessas abelhas, que possibilita a exploraração localidades próximas. Fatores climáticos, diferença na volatilidade das substâncias, faixa etária das populações, pureza e composição isométricas das substâncias e ofertas de fontes naturais podem ter influenciado nesse resultado. Apesar dos resultados mostrarem um alto grau de degradação na área estudada, é necessário a realização de mais estudos, que levem em conta o tamanho dos fragmentos e o número de Eulaema nigrita em relação a outras espécies para que se possa obter dados mais precisos sobre os impactos dos diferentes usos da terra na diversidade das abelhas Euglossini.
