Abstract

NEVES, Edinaldo Luz das  and  VIANA, Blandina Felipe. Inventory of the Euglossinae (Hymenoptera, Apidae) fauna of southern Bahia, Brazil. Rev. Bras. Zool. [online]. 1997, vol.14, n.4, pp. 831-837. ISSN 0101-8175.  http://dx.doi.org/10.1590/S0101-81751997000400007.

This paper reports the results concerning collection of Euglossinae bees in a mangrove ecosystem in Valença(13º22'08"S and 39º04'20"W), Bahia. These samples were made twice a month, for a year. The chemical baits Citronella, Eucalyptol, Eugenol, Metyl Salicylate and Vanillin attracted 1,144 specimens distributed among twelve species and two genera: Eulaema (Lepeletier, 1841) and Euglossa (Latreille, 1802). The predominam bee species was Eulaema nigrita (Lepeletier, 1841) consisting of 49.4% of the collected specimens, followed by Euglossa cordata (Linnaeus, 1758) with 44.88%, Euglossa imperialis (Cockerell, 1922) with 2.4% and Eulaema meriana flavescens (Friese, 1899) with 1.6%. Theothers species, considering sporadic visitors, Euglossa securigera (Dressler, 1982), Euglossa chalybeata (Friese, 1925), Euglossa liopoda (Dressler, 1982), Euglossa gaianii (Dressler, 1982), Euglossa townsendi (Cockerell, 1904), Euglossa truncata (Rebelo & Moure, 1995), Euglossa melanotricha (Moure, 1967) and Euglossa sapphirina (Moure, 1968) represented together only 1.8% of the total sample. The Euglossinae were more active from October to May. Eucalyptol was the most attractive bait, attracting 1,120 specimens. Methyl Salicylate attracted 17 specimens, followed by Eugenol, which attracted 04 specimens and Vanillin, which attracted 03 specimens. Citronella was not an attractive chemical.
