Western corn rootworm (WCR), or LeConte, became a very serious quarantine maize pest in Europe in the mid-1990s. Between 1995 and 2010, European countries were involved in international projects to share information and plan common research for integrated pest management (IPM) implementation. Since 2011, however, common efforts have declined, and an overview of WCR population spread, density, and research is in serious need of update. Therefore, we retained that it was necessary to (1) summarize the research activities carried out in the last 12 years in various countries and the research topics addressed, and analyze how these activities have contributed to IPM for WCR and (2) present the current distribution of WCR in the EU and analyze the current population levels in different European countries, focusing on different management strategies. A review of scientific papers published from 2008 to 2020, in addition to direct interviews with experts in charge of WCR management in a range of European countries, was conducted. Over the past 12 years, scientists in Europe have continued their research activities to investigate various aspects of WCR management by implementing several approaches to WCR control. A considerable amount of new knowledge has been produced, contributing to the development of pest management strategies applicable in EU farming systems. Among the 10 EU countries analyzed, there is no country reporting economic damage on a large scale. Thanks to intensive research leading to specific agricultural practices and the EU Common Agricultural Policy, there are crop-rotation-based solutions that can adequately control this pest avoiding insecticide use.
西部玉米根萤叶甲（WCR），即 LeConte，在20世纪90年代中期成为欧洲一种非常严重的检疫性玉米害虫。1995年至2010年期间，欧洲国家参与了国际项目，以共享信息并规划综合虫害管理（IPM）实施方面的共同研究。然而，自2011年以来，共同努力有所减少，WCR种群扩散、密度及研究的概述迫切需要更新。因此，我们认为有必要：（1）总结过去12年各国开展的研究活动及涉及的研究主题，并分析这些活动如何促进了WCR的综合虫害管理；（2）介绍WCR在欧盟的当前分布情况，并分析不同欧洲国家的当前种群水平，重点关注不同的管理策略。我们对2008年至2020年发表的科学论文进行了综述，并直接采访了一系列欧洲国家负责WCR管理的专家。在过去12年里，欧洲科学家通过实施多种WCR控制方法，继续开展研究活动，以调查WCR管理的各个方面。已经产生了大量新知识，有助于制定适用于欧盟农业系统的虫害管理策略。在分析的10个欧盟国家中，没有一个国家报告有大规模的经济损失。由于深入研究产生了特定的农业实践方法以及欧盟共同农业政策，存在基于作物轮作的解决方案，能够在避免使用杀虫剂的情况下充分控制这种害虫。
