Orchid bees subsist in vast tropical forest areas because they maintain close relationships with particular plant species in diverse micro-habitats. Based on the relationships among the environment and biological features (food preference, morphologic and ethologic diversity), it is possible to determine habitat quality using the euglossine array. This work proposes the use of this ecological information, in addition to diversity indices, for the evaluation of environmental quality. Fifteen localities in three landscape types (urban, rural and conserved) were sampled in the eastern llanos foothill (Meta, Colombia), between March and December of 2003 using entomological nets, and Cineol and Metil Salicylate as baits. Of the 26 species known to occur in the area, 17 were registered. Eulaema nigrita was the most frequent, while E. speciosa E. bombiformis, Euglossa magnipes, E. cybelia, E. heterosticta, E. singularis and Exaerete frontalis were mostly found in habitats rated "good to acceptable". The vegetation composition and proximity of forest fragments seem to favor some species in disturbed habitats. Relative diversity of bee body shapes and sizes is proportional to habitat quality.
兰花蜂栖息于广阔的热带森林地区,因为它们与不同微生境中的特定植物物种保持着密切关系。基于环境与生物学特征(食物偏好、形态和行为多样性)之间的关系,利用兰花蜂群落有可能确定栖息地质量。这项研究除了使用多样性指数外,还建议利用这些生态信息来评估环境质量。2003年3月至12月期间,在哥伦比亚梅塔省东部平原山麓的三种景观类型(城市、农村和保护区)中的15个地点,使用昆虫网,以桉叶油和水杨酸甲酯作为诱饵进行采样。在该地区已知出现的26个物种中,记录到了17种。黑大蜜蜂最为常见,而华丽大蜜蜂、球形大蜜蜂、大足 Euglossa magnipes、cybelia Euglossa、异纹 Euglossa heterosticta、奇异 Euglossa singularis 和额突 Exaerete frontalis 大多出现在评级为“良好至可接受”的栖息地中。植被组成和森林碎片的 proximity 似乎有利于一些处于受干扰栖息地的物种。蜜蜂体型和大小的相对多样性与栖息地质量成正比。 (注:原文中“proximity”可能有误,推测应为“ximity”,但不影响整体理解,暂按原文翻译)
