Background Halyomorpha halys (Stål, 1855), the brown marmorated stinkbug (BMSB) is a highly successful invasive species, native to eastern Asia. It has managed to spread into North America and Europe in recent decades, causing severe damage to various crops. BMSB has been detected in Europe in 2004 and has since expanded in more than 20 countries from Sweden to Greece and Spain to Turkey, the South European Territory of Russia (Krasnodar region) and Abkhazia. In 2012, we set up a citizen science survey to monitor BMSB expansion in France. New information The present crowdsourcing survey was initiated in 2012 and provided a large number of occurrence points of BMSB. These data allowed to track the expansion of the species in France from 2012 to 2019 and brought information about its phenology and distribution in various habitats. The dataset comprises both valid and invalid sightings, thereby allowing us to examine changes in the quality of citizen reports during the course of the survey. Despite a large proportion of misidentifications, the survey provided a large number of valid occurrences. Furthermore, valuable information on hemipterans of Pentatomidae and Coreidae families entering habitations were also gathered. The dataset also illustrates that, although designed for a large public, the Agiir application was mostly used by urban dwellers with very few sightings stemming from professionals of agricultural sectors.

一种众包方法来跟踪法国褐栗臭虫 Halyomorpha halys (Stål, 1855) 的扩张情况

背景 Halyomorpha halys (Stål, 1855)，褐斑蝽 (BMSB) 是一种非常成功的入侵物种，原产于东亚。近几十年来，它已成功传播到北美和欧洲，对各种农作物造成了严重破坏。BMSB 于 2004 年在欧洲被发现，此后已扩展到 20 多个国家，从瑞典到希腊，从西班牙到土耳其、俄罗斯的南欧领土（克拉斯诺达尔地区）和阿布哈兹。2012 年，我们开展了一项公民科学调查，以监测 BMSB 在法国的扩张情况。新信息 本次众包调查于2012年启动，提供了大量BMSB的发生点。这些数据可以追踪该物种从 2012 年到 2019 年在法国的扩张情况，并带来有关其物候学和在各种栖息地分布的信息。该数据集包含有效和无效的目击记录，从而使我们能够在调查过程中检查公民报告质量的变化。尽管存在很大比例的错误识别，但该调查提供了大量有效的事件。此外，还收集了有关蝾螈科和蝼蛄科半翅目进入栖息地的宝贵信息。该数据集还表明，尽管 Agiir 应用程序是为广大公众设计的，但主要由城市居民使用，很少有来自农业专业人士的目击事件。此外，还收集了有关蝾螈科和蝼蛄科半翅目进入栖息地的宝贵信息。该数据集还表明，尽管 Agiir 应用程序是为广大公众设计的，但主要由城市居民使用，很少有来自农业部门专业人士的目击事件。此外，还收集了有关蝾螈科和蝼蛄科半翅目进入栖息地的宝贵信息。该数据集还表明，尽管 Agiir 应用程序是为广大公众设计的，但主要由城市居民使用，很少有来自农业部门专业人士的目击事件。
