亚洲地下白蚁（Coptotermes gestroi）是一种重要的经济结构和农业害虫，已在世界许多地区建立。首次用系统地理学的方法阐明了在美国波多黎各联邦新发现的C gestroi的起源；美国俄亥俄州;美国佛罗里达州;以及澳大利亚的布里斯班。利用3个基因（16S rRNA、COII和ITS），在3个最优标准下(包括表型和枝系假设（最大简约性、最大似然性和邻居联结性），研究了在马来西亚、泰国和新加坡本土以及4个引种地区采集的C gestroi的系统发育关系。这三个基因一致地支持了来自新加坡和俄亥俄州的白蚁样本之间的密切遗传关系，而来自澳大利亚、波多黎各和佛罗里达州基韦斯特的白蚁样本与来自马来西亚的白蚁样本之间的密切遗传关系。航运记录进一步证实，新加坡和马来西亚可能分别是俄亥俄和澳大利亚C. gestroi的起源。这些数据为利用系统地理学来了解外来白蚁的传播历史提供了依据。偶然的是，我们也从鼻白蚁的两个属物种的ITS集群中获得了协同进化的见解。(c) 2006爱思唯尔公司版权所有。
Coptotermes gestroi, the Asian subterranean termite (AST), is an economically important structural and agricultural pest that has become established in many areas of the world. For the first time, phylogeography was used to illuminate the origins of new found C gestroi in the US Commonwealth of Puerto Rico; Ohio, USA; Florida, USA; and Brisbane, Australia. Phylogenetic relationships of C gestroi collected in indigenous locations within Malaysia, Thailand, and Singapore as well as from the four areas of introduction were investigated using three genes (16S rRNA, COII, and ITS) under three optimality criteria encompassing phenetic and cladistic assumptions (maximum parsimony, maximum likelihood, and neighbor-joining). All three genes showed consistent support for a close genetic relationship between C gestroi samples from Singapore and Ohio, whereas termite samples from Australia, Puerto Rico, and Key West, FL were more closely related to those from Malaysia. Shipping records further substantiated that Singapore and Malaysia were the likely origin of the Ohio and Australia C. gestroi, respectively. These data provide support for using phylogeography to understand the dispersal history of exotic termites. Serendipitously, we also gained insights into concerted evolution in an ITS cluster from rhinotermitid species in two genera. (c) 2006 Elsevier Inc. All rights reserved.
