The two largest Atlantic Forest remnants in the state of Espírito Santo, eastern Brazil, namely 'Reserva Biológica de Sooretama' (REBIO Sooretama) and 'Reserva Natural Vale' (RNV), were surveyed for their orchid-bee faunas. Seventeen scent baits were used to attract orchid-bee males. Three-thousand, two hundred and twenty-five males belonging to 24 species were actively collected with insect nets during 100 hours in March, April and December, 2009. In comparison with a previous study in the same area twelve years before, it is evident that the abundance of all forest-dependent orchid bees analysed declined around 50%, and it was statistically significant (P = 0.022) for Euglossa marianae Nemésio, 2011, the most sensitive to anthropogenic disturbances of all Atlantic Forest orchid bees. On the other hand, the abundance of populations of species tolerant to open or disturbed areas rose. Possible explanations are discussed.
对巴西东部圣埃斯皮里图州两个最大的大西洋森林遗迹，即“索雷塔马生物保护区”（REBIO索雷塔马）和“瓦尔自然保护区”（RNV）的兰花蜂动物群进行了调查。使用了17种气味诱饵来吸引兰花蜂雄蜂。2009年3月、4月和12月，在100小时内用昆虫网积极收集了属于24个物种的3225只雄蜂。与12年前在同一地区进行的一项先前研究相比，很明显，所有分析的依赖森林的兰花蜂的数量下降了约50%，对于2011年的玛丽安娜兰花蜂（Euglossa marianae Nemésio）来说，这具有统计学意义（P = 0.022），它是所有大西洋森林兰花蜂中对人为干扰最敏感的。另一方面，耐开阔或受干扰地区的物种数量有所增加。文中讨论了可能的解释。
