The two most used sampling methods in euglossine studies were used simultaneously: insect nets and bait traps. We collected 1,744 euglossine specimens belonging to at least 33 species. Of these, 1,221 were collected with insect nets and 523 in bait traps. Eulaema cingulata (Fabricius) and Eulaema meriana (Olivier) were the commonest species in both the Parque Zoobotânico and the Catuaba Reserve, followed by Euglossa amazonica Dressler, Euglossa ignita Smith, and Euglossa mixta Friese. Due to a combination of ‘dominant species’ and the specific composition of the orchid-bee fauna of the studied areas, the Acrean orchid-bee fauna has shown to be quite different from other areas sampled in Amazonia. As the sampling effort with bait traps was twice as higher as that with insect nets, the efficiency of the insect net method was 4.7 times greater, in average, than that with bait traps. Thirty-two of the 33 species were collected with insect nets, whereas only 24 species were collected with bait traps. The resulting community of orchid bees was also different. The large bees of the genus Eulaema Lepeletier were much more abundant in bait-trap (74% - 79%) than in insect net samples (37% - 39%). The considerable differences in efficiency between insect nets and bait trap collections suggest that the sole use of bait traps should be avoided in orchid bee studies or restricted to situations in which the use of insect nets is impossible. \u0000Key words: Amazonia, chemical baits, euglossine bees, Hymenoptera, insect nets, Insecta.","PeriodicalId":445542,"journal":{"name":"Lundiana: International Journal of Biodiversity","volume":"360 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126695471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The behavior of the predominant visiting bees Xylocopa (Neoxylocopa) cearensis Ducke 1910 and Centris (Centris) leprieuri Spinola 1841 was recorded with the aim of identifying their role as potential pollinators. The corolla is yellow, small, zigomorphic and homogamic. Anthesis is diurnal and longevity reaches ca 2 d (n=58); flowering synchrony is low (0.43) at the population level, resulting in a long flowering period. Mean nectar volume for first (2.13 ± 0.93 mL, n=27) and second day (0.96 ± 0.60 mL, n=26) flowers differed significantly (t=5.741, p<0.0001). Nectar concentration was lower in first day flowers (20%) than in second day flowers (26%), probably due to the reduction in volume caused by evaporation. Fruit formation was low in manual self-pollination (7%) and absent for spontaneous self-pollination. The highest percentage of fruit formation (89%) was found in control (natural conditions), suggesting that pollen vectors are important for the reproduction of C. brachiata. X cearensis and C. leprieuri collect nectar by landing on the four lower petals and introduicng their head into the corolla tube. Pollen adheres to the bee’s forehead at the same place that contact the reproductive structures of the flower. X. cearensis is the most efficient pollinator of C. brachiata, considering its local abundance, pattern of foraging activity, frequency of contact with reproductive structures and pollen transport. \u0000Keywords: floral biology, Cuphea brachiata, pollination.","PeriodicalId":445542,"journal":{"name":"Lundiana: International Journal of Biodiversity","volume":"69 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132478157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Schum. (Bignoniaceae), in the coastal strand vegetation (restinga) of Maricá RJ., between 1997 and 2000. The flowers display daytime anthesis, are yellow, very attractive, tubulous, hermaphrodite, odoriferous and produce nectar as the floral reward. The nectar is secreted by a nectariferous disk and accumulated in a chamber. The stigmas are bifid, wet and papillous. The stigmatic lobes are receptive to pollen only on the inner surfaces and are sensitive to disturbance. If the stigma is touched but no pollen is deposited, the lobes close and soon reopen. The same occurs when self-pollen is deposited on the receptive surface. However, after manual pollination with cross-pollen the lobes close permanently, enabling to estimate levels of pollination by monitoring stigma closure. Euglossa cordata L., Epicharis dejeanii Lepeletier and E. semiflava Moure are potential pollinators. Xylocopa ordinaria Smith is the primary nectar robber. The species is self-incompatible and has a low fruit set (Fruit/Flower=4.86%). The flowering pattern is the “multiple bang”, showing five episodes per year, with the same intensity, all of them occurring in the most hot and rainy months. \u0000Keywords: Anemopaegma chamberlaynii, floral biology, reproduction, restinga, phenology.","PeriodicalId":445542,"journal":{"name":"Lundiana: International Journal of Biodiversity","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115109288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
