The use of biological control agents to control pests is an alternative to pesticides and a tool to manage invasive alien species. However, biocontrol agents can themselves become invasive species under certain conditions. The harlequin ladybird () is a native Asian biocontrol agent that has become a successful invader. We reviewed articles containing "" to gather information on its presence and surveyed entomologists researching Coccinellidae around the world to investigate further insights about the current distribution, vectors of introduction, habitat use and threats this species pose. The harlequin ladybird has established populations in at least 59 countries outside its native range. Twenty six percent of the surveyed scientists considered it a potential threat to native Coccinellidae. Published studies and scientists suggest , native to Europe, is under the highest risk of population declines. Strict policies should be incorporated to prevent its arrival to non-invaded areas and to prevent further expansion range. Managing invasive species is a key priority to prevent biodiversity loss and promote ecosystem services.
使用生物防治剂来控制害虫是农药的一种替代方法，也是管理外来入侵物种的一种手段。然而，生物防治剂在某些情况下自身也可能成为入侵物种。异色瓢虫是一种原产于亚洲的生物防治剂，现已成为一种成功的入侵物种。我们查阅了包含“异色瓢虫”的文章，以收集有关其分布情况的信息，并调查了世界各地研究瓢虫科的昆虫学家，以进一步了解该物种目前的分布、引入途径、栖息地利用情况以及它所构成的威胁。异色瓢虫已在其原生范围之外的至少59个国家建立了种群。26%的受访科学家认为它对本地瓢虫科构成潜在威胁。已发表的研究和科学家表明，原产于欧洲的[某种瓢虫]面临种群数量下降的风险最高。应制定严格政策，防止其进入未受入侵的地区，并防止其进一步扩大分布范围。管理入侵物种是防止生物多样性丧失和促进生态系统服务的关键优先事项。
