Male euglossine bees were collected in the savannas (Cerrado) of Barreirinhas, in the western coastal lowland zone of Maranhão State. Animals were baited with cineole, eugenol, methyl salicylate and benzyl benzoate. Nine species belonging to 4 genera were found. Euglossa cordata was the most abundant (63,31%), followed by Eulaema cingulata (17,80%), Eulaema nigrita (7,63%), Euglossa modestior (4,94%) and Eufriesea ornata (4,16%). The others Euglossa chalybeata, Euglossa fimbriata, Euglossa melanotricha and Exaerete smaragdina, were less frequently found, representing only 2,16% of the total sample (combined). The bees were active in both the rains and dry seasons, especially on the first. Cineole was the most attractive aromatic compound (78,2% of specimens and 8 species), followed by eugenol (19,9% and 5 species), benzyl benzoate (0,6% and 2 species) and methyl salicylate (1,3% and 1 species).
