In this project funded by the Americas Program of the Office of International Science and Engineering, Philip S. Ward and Alexander Wild will provide a taxonomic revision and phylogenetic analysis of the Neotropical ant genus Linepithema Mayr 1866. This project is a collaborative effort with John A. Kochalka at the Museo Nacional de Historia Natural in Paraguay. It involves field work in the center of diversity for Linepithema in southern South America, museum visits to examine important myrmecological collections and type specimens in South America and Europe, and development of DNA sequence data to be used in phylogenetic reconstruction.Linepithema is an extremely important invasive ant, and the Argentine ant L. humile is highly successful and one of the most damaging invasive pest ants worldwide. A proper taxonomic treatment of this group is required for its correct identification and potential management through bio-control. The results of the project will be posted on the Internet and will be accessible to a very broad audience. On a broader scale, this study should help provide a more rigorous understanding of the nature of invasive species as a whole. The field work abroad will provide an international experience that will enhance a graduate student's training.

在这项由国际科学与工程办公室美洲计划资助的项目中，菲利普·S·沃德和亚历山大·怀尔德将对新热带蚂蚁属Linephema Mayr 1866进行分类修订和系统发育分析。这个项目是与巴拉圭国家历史博物馆的约翰·A·科查尔卡合作完成的。它包括在南美洲南部线虫多样性中心的实地工作，参观博物馆以检查南美洲和欧洲重要的真菌生态收藏品和模式标本，以及开发用于系统发育重建的DNA序列数据。线虫是一种极其重要的入侵蚂蚁，阿根廷蚂蚁L.Humile是非常成功的，也是世界上最具破坏性的入侵蚂蚁之一。对这一群体进行适当的分类处理是正确识别和通过生物防治进行潜在管理所必需的。该项目的结果将在互联网上公布，并将向非常广泛的受众开放。在更广泛的范围内，这项研究应该有助于更严格地理解入侵物种作为一个整体的性质。国外的实地考察将提供一种国际经验，这将加强研究生的培训。
