Resumo

In order to investigate phenological patterns and seasonal and geographic variations in the preference for fragrances of Euglossini males, monthly sampling was carried out from August 2007 to July 2009 in two coastal areas of Atlantic Forest in Ubatuba, northern coast of the state of So Paulo. Fourteen aromatic baits were used, 3 of them in the first year (August 2007 to July 2008) and the other 11 in the second year (August 2008 to July 2009). A total of 1,475 individuals from 22 species were collected. The highest frequency of the individuals of the majority of the sampled species occurred in the hot/super-humid season. However, Eulaema cingulata (Fabricius) showed peaks of abundance in the cold/less-humid season on Anchieta Island. Seasonal variation in fragrance choice by males was not registered. Males of El. cingulata showed preference for beta-ionone on Anchieta Island and for benzyl acetate in the Picinguaba region, characterizing the single example of geographic variation in preference for scent baits we recorded.
