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 São 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 β-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.
为了研究尤金蜂雄蜂对香味的物候模式、季节和地理变化，2007年8月至2009年7月期间，在圣保罗州北部海岸乌巴图巴的大西洋森林的两个沿海地区进行了月度采样。使用了14种芳香诱饵，其中3种在第一年（2007年8月至2008年7月）使用，另外11种在第二年（2008年8月至2009年7月）使用。共收集到来自22个物种的1475只个体。大多数采样物种的个体出现频率最高的是在炎热/超湿润季节。然而，在安基埃塔岛，带纹尤拉蜂（Eulaema cingulata (Fabricius)）在寒冷/较干燥季节出现数量峰值。未记录到雄蜂对香味选择的季节变化。在安基埃塔岛，带纹尤拉蜂的雄蜂对β-紫罗兰酮表现出偏好，而在皮钦古阿巴地区则对乙酸苄酯表现出偏好，这是我们记录到的对气味诱饵偏好存在地理变化的唯一实例。
