Abstract

The orchid-bee fauna of the region of Porto Velho, in the state of Rondônia, Brazil, close to the southernmost limits of the Amazon Basin, was surveyed for the first time using five different scents as baits to attract orchid-bee males. Five hundred and twenty-one males belonging to five genera and 29 species were collected with bait traps during 26 non-consecutive days from November, 2011 to January, 2012. Eulaema nigrita Lepeletier, 1841 and Eulaema meriana (Olivier, 1789) were the most common species in the region and, together, represented almost 50% of all collected bees. Although the observed richness conforms to similar inventories in the region, the diversity (H'= 2.43) found in the present study is one of the highest ever recorded for orchid bees in the Amazon Basin.

摘要

巴西朗多尼亚州韦柳港地区靠近亚马逊盆地最南端边界，首次使用五种不同气味作为诱饵来吸引兰花蜂雄性个体，对该地区的兰花蜂动物群落进行了调查。在2011年11月至2012年1月的26个非连续日期间，用诱饵陷阱捕获了属于5个属29个物种的521只雄性个体。1841年的黑带尤拉蜂和1789年的梅里安娜尤拉蜂是该地区最常见的物种，两者合计占所有采集到的蜜蜂的近50%。尽管观察到的丰富度与该地区类似的调查结果相符，但本研究中发现的多样性（H'= 2.43）是亚马逊盆地兰花蜂有记录以来最高的之一。
