警惕南方黏虫传入我国

原产于美洲热带的南方黏虫Spodoptera eridania(Stoll)是一种多食性的农业害虫。2016年南方黏虫入侵到非洲4个国家，对木薯和番茄等作物造成了严重危害，目前在我国尚未发现该害虫及相关报道。本文综述了南方黏虫的形态特征、地理分布、生物学特性以及防治措施，为我国今后南方黏虫的检测、监测和防治工作提供参考。从适生性度看，南方黏虫的寄主植物在我国广泛分布；我国也存在气候环境与该虫生存条件相似的地区，且寄主植物所在区域的气候条件同样适于南方黏虫的生长发育。伴随着国际贸易和其自身强大的迁飞能力，南方黏虫具有入侵我国的可能性。因此，有必要对其入侵我国的威胁提出预警，加强边境口岸检疫是防范该虫入侵的主要手段。

Precaution of southern armyworm, Spodoptera eridania (Stoll), potential invasive pest in China

Southern armyworm, Spodoptera eridania (Stoll), native to tropical America, is a polyphagous agricultural pest. In 2016, southern armyworm invaded four countries in Africa causing serious harm to crops such as cassava and tomato. At present, the pest has not been found in China yet and with lack of Chinese literatures. This paper summarized its morphological characteristics, geographical distribution, biological characteristics and control measures, which may provide a reference for the detection and monitoring. Furthermore, there are plenty of host plants and suitable areas for its survival in China. The important point is that there were suitable overlapping ranges for both host plants and southern armyworm in regard to the climatic conditions. Therefore, this pest has the possibility of invading China in the future with international trade and its strong migratory ability. It is worthwhile to give early warning to the threat of invasion, and strengthening quarantine at border ports is the main means to prevent its invasion.
