Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 3
Abstract
The bees of the Euglossina subtribe are widely distributed in the Neotropical region, being more diversified in the humid forests. The purpose of this research was to carry out a survey of the species of this subtribe in a fragment of Atlantic Forest, a remnant of altitude swamp, located in a region of the Brazilian Semiarid. The study was conducted in the municipality of Portalegre, Rio Grande do Norte, between February and August 2015. Data collection was performed monthly between 08h00 and 16h00, using traps containing the eucalyptol, eugenol and vanillin essences. A total of 123 males, distributed in four genera and six species were collected, which are: Eufriesea danielis (43.09%), Euglossa melanotricha (25.20%), Euglossa cordata (15.45%), Eulaema nigrita (13.82%), Euglossa fimbriata (1.63%) and Exaerete dentata (0.81%). The interval between 8:00 a.m. and 10:00 was the most active, with 54.4% of the total collected males. The community of the bees studied region showed greater preference for eucalyptol, attracting five species and 67 individuals (53.6%). The species Eufriesea danielis is reported here the first time for the Northeast region of Brazil, while Exaerete dentata has its first record for the state of Rio Grande do Norte.
