The Argentine ant, Linepithema humile (Dolichoderinae), is one of the most widespread invasive ant species in the world. When established in optimal habitat, this species usually excludes most other local ants and can heavily impact other arthropods as well. Although Argentine ants have been present in southern Europe for more than 100 years, they were first noted in Corsica, a French Mediterranean island, in 1957 in only one urban station. In this study, we aimed to map precisely their geographical distribution in Corsica and to quantify their presence by using an infestation index. We recorded changes in the distribution of Argentine ants in Corsica over the past decade. Argentine ants appeared to be well established within their introduced range and spreading along the Corsican coasts principally through Human-mediated jump-dispersal but not homogenously.
阿根廷蚁（Linepithema humile，蚁亚科）是世界上分布最广的入侵蚁种之一。当在适宜栖息地定殖后，该物种通常会排挤掉大多数其他本地蚂蚁，并且对其他节肢动物也会产生严重影响。尽管阿根廷蚁在南欧已存在100多年，但它们于1957年首次在法国地中海岛屿科西嘉岛被发现，当时仅在一个城市地点。在本研究中，我们旨在精确绘制它们在科西嘉岛的地理分布，并通过使用侵染指数来量化它们的存在情况。我们记录了过去十年中科西嘉岛阿根廷蚁分布的变化。阿根廷蚁似乎在其引入范围内已很好地定殖，并主要通过人类介导的跳跃扩散沿着科西嘉岛海岸扩散，但并非均匀扩散。
