We report the first detection of Fall Armyworm (FAW), Spodoptera frugiperda (Smith, 1797), in Bhutan. FAW feeds on more than 300 plant species and is a serious pest of many. It has been spreading through Africa since 2016 and Asia since 2018. In Bhutan, this species was first detected in maize fields in the western part of the country in September 2019 and subsequently found infesting maize crops in southern parts of the country in December 2019 and April 2020. Using morphological and molecular techniques the presence of the first invading populations of S. frugiperda in Bhutan is confirmed through this study. We present an updated reference DNA barcode data set for FAW comprising 374 sequences, which can be used to reliably identify this serious pest species, and discuss some of the reasons why such compiled reference data sets are necessary, despite the public availability of the underlying data. We also report on a second armyworm species, the Northern Armyworm, Mythimna separata (Walker, 1865), in rice, maize and other crops in eighteen districts of Bhutan.

秋季粘虫Spodoptera frugiperda)的最新全球COI条码参考数据集,以及该物种在不丹的首次记录

我们报告了在不丹首次发现秋天粘虫(FAW),Spodoptera frugiperda(史密斯,1797年)。一汽以300多种植物为食,是许多植物的严重害虫。自2016年以来一直在非洲传播,自2018年以来一直在亚洲传播。在不丹,该物种于2019年9月在该国西部的玉米田中首次发现,随后于2019年12月在该国南部发现了侵染性玉米作物, 2020年4月。使用形态学和分子技术,发现了第一批入侵的弗氏链球菌。这项研究证实了不丹的存在。我们提供了一个由374个序列组成的一汽更新的参考DNA条码数据集,可用于可靠地识别这种严重的有害生物种类,并讨论了尽管基础数据可公开获得,但仍需要这种汇编参考数据集的一些原因。我们还报告了不丹十八区水稻,玉米和其他农作物中的第二种夜蛾物种,北部夜蛾,Mythimna separata(Walker,1865年)。
