Antarctica currently has few non-native species, compared to other regions of the planet, due to the continent’s isolation, extreme climatic conditions and the lack of habitat. However, human activity, particularly the activities of national government operators and tourism, increasingly contributes to the risk of non-native species transfer and establishment. Trichocera (Saltitrichocera) maculipennis Meigen, 1888 (Diptera, Trichoceridae) is a non-native fly originating from the Northern Hemisphere that was unintentionally introduced to King George Island in the maritime Antarctic South Shetland Islands around 15 years ago, since when it has been reported within or in the vicinity of several research stations. It is not explicitly confirmed that T. maculipennis has established in the natural environment, but life-history characteristics make this likely, thereby making potential eradication or control a challenge. Antarctic Treaty Parties active in the region are developing a coordinated and expanding international response to monitor and control T. maculipennis within and around stations in the affected area. However, there remains no overarching non-native invasive species management plan for the island or the wider maritime Antarctic region (which shares similar environmental conditions and habitats to those of King George Island). Here we present some options towards the development of such a plan. We recommend the development of (1) clear mechanisms for the timely coordination of response activities by multiple Parties operating in the vicinity of the introduction location and (2) policy guidance on acceptable levels of environmental impacts resulting from eradication attempts in the natural environment, including the use of pesticides.

由于地球的孤立，极端的气候条件和缺乏栖息地，与地球上的其他地区相比，南极洲目前很少有非本地物种。但是，人类活动，特别是国家政府经营者的活动和旅游业，日益增加了非本地物种转移和建立的风险。Trichocera（Saltitrichocera）maculipennis Meigen，1888（Diptera，Trichoceridae）是起源于北半球的一种非本地蝇，大约在15年前被无意地引入了海洋南极南设得兰群岛的乔治国王岛，自从有报道以来在几个研究站之内或附近。尚未明确证实斑纹丁香已在自然环境中建立，但生活史特征使其成为可能，从而使潜在的根除或控制成为挑战。活跃在该地区的南极条约缔约方正在制定协调一致的国际对策，以监测和控制斑潜蝇。在受灾地区的车站内和车站周围。但是，对于该岛或更广阔的海洋南极地区（与乔治王岛拥有相似的环境条件和栖息地），仍然没有总体的非本地入侵物种管理计划。在这里，我们提出了制定这种计划的一些选择。我们建议建立（1）明确的机制，以便在引入地点附近开展活动的多个缔约方及时协调应对活动，以及（2）关于在自然环境中进行根除尝试而造成的可接受的环境影响的政策指导，包括使用农药。
