中文摘要：

为了探究西双版纳地区将自然森林转换成橡胶林后，盘猛蚁属（Discothyrea Roger）蚂蚁在自然森林片段和橡胶林中的分布状况，采用Winkler分离法收集蚂蚁，依据形态学鉴定方法，鉴定盘猛蚁属蚂蚁。研究共收集到两种盘猛蚁属蚂蚁：滇盘猛蚁（Discothyrea diana）和版纳盘猛蚁（Discoth yrea banna），且均来自于枯落物较为丰富的自然森林片段，而在橡胶林中没有发现。说明了将自然森林转换成单一作物的橡胶林，会影响盘猛蚁属蚂蚁的群落分布。

英文摘要：

In order to assess the distribution of ant genusDiscothyrea Roger in forest fragments and rubber plantations after converting forests into rubber plantations in Xishuangbanna, ants were collected by Winkler bags and identified into species based on morphological taxonomy. Two species of ant genusDiscothyrea Roger, Discothyrea diana and Discothyrea banna, were found in forest fragments with much leaf litter. However, no ant genus Discothyrea Roger was found in rubber plantations. Our study showed that transforming forests to monocultural rubber plantations has impacts on the distribution of ant genus Discothyrea Roger.
