Male orchid bees were collected by chemical baiting in four forest fragments in parks of the city of Belo Horizonte, Minas Gerais, southeastern Brazil. One thousand three hundred and twenty-five males belonging to 14 species were captured within one year. The capture data were compared through correlation tests. The data suggest that abundance of orchid bees tend to increase with fragment size, although no correlation between species richness and fragment size was obtained. The results presented herein suggest that forest fragments in a large city may be of importance concerning conservation of orchid-bee faunas.
在巴西东南部米纳斯吉拉斯州贝洛奥里藏特市公园的四个森林片段中,通过化学诱饵收集雄性兰花蜂。一年内捕获了属于14个物种的1325只雄性兰花蜂。通过相关性测试对捕获数据进行比较。数据表明,尽管未获得物种丰富度与片段大小之间的相关性,但兰花蜂的数量往往会随着片段大小的增加而增加。本文给出的结果表明,大城市中的森林片段对于兰花蜂动物群的保护可能具有重要意义。
