摘要
草地螟Loxostege sticticalis是一种世界性重大迁飞害虫,广泛分布于36°N-53°N之间,对欧洲、亚洲和北美洲多个国家的农、牧、林业生产安全造成重大威胁。蒙古国与我国新疆和内蒙古等草地螟发生区相邻,该国草地螟的发生对我国草地螟发生为害和预测预报有重要影响。为提高我国草地螟预测预报准确率,加强跨境源头治理,本文系统综述了蒙古国草地螟发生、为害概况、越冬场所以及跨境迁飞等研究进展;阐明了草地螟可在蒙古国全国范围内发生,周期性为害牧草、油菜和胡麻等经济作物以及草原植被等。幼虫在蒙古国中东部、北部和东南部越冬,越冬代和一代成虫均可随气流迁入到我国境内,同时我国华北草地螟越冬代也可跨境迁入到蒙古国。两国草地螟越冬区虫源互为迁飞虫源,对两国虫情发生和作物受害程度产生重要影响。为此,提出了加强中蒙草地螟跨境迁飞监测与源头治理等国际合作建议,以期提高两国草地螟早期预警水平,实现关口前移,源头治理。
The beet webworm,Loxostege sticticalis,a major migratory insect pest,with a global distribution between 36°N and 53°N,posing a major threat to agricultural,grassland,and forestry production across multiple countries in European,Asian and North American.Mongolia shares a border with key L.sticticalis outbreak regions in Xinjiang and Inner Mongolia,China,and population dynamics of L.sticticalis in Mongolia play a crucial role in forecasting and managing its outbreaks in China.To enhance early warning accuracy and cross-border pest control efforts,this study systematically reviews the occurrence,distribution,damage,overwintering sites and transboundary migration of L.sticticalis in Mongolia.It was found that L.sticticalis is widely distributed across Mongolia,causing periodic damage to pastures,rapeseed,flax,and other economic crops,as well as natural grassland vegetation.The larvae overwinter in the east-central,northern,and southeastern regions of Mongolia.Both overwintering generation and first-generation moths can immigrate into China via atmospheric currents,contributing to outbreaks.Likewise,overwintering L.sticticalis populations from North China can also migrate into Mongolia,indicating that the overwintering populations in both countries serve as mutual migratory sources,significantly influencing pest outbreaks and crop damage.Given these transboundary movements,we propose strengthening China-Mongolia collaboration on cross-border migration monitoring and source population management.Such international cooperation is essential for improving early warning systems and implementing proactive pest control strategies to mitigate L.sticticalis outbreaks at their source.
