摘    要:为了证实草地螟Loxostege sticticalis L.(鳞翅目: 螟蛾科)由我国华北越冬区向东北迁飞危害的假说并提供直接的证据, 采用网捕成虫喷雾染料标记释放回收的方法,于2009年越冬代草地螟成虫盛发期间(6月1-4日)分别在内蒙古武川县(41.07°N, 111.42°E)和察右中旗(41.13°N, 112.58°E)的6个标放点共标记当地越冬代草地螟成虫约181万头并自然释放。标记释放后, 在东北、 西北和华北11个草地螟常发省(市、 区)组织各级监测预警部门利用虫情测报灯、 捕虫网和性诱剂诱捕器等多种器械进行回收, 先后于2009年6月7-29日在内蒙古科右中旗、 乌兰浩特、 扎兰屯分别回收到由察右中旗标记释放的成虫9头, 在辽宁省北票市回收到由武川县标记释放的成虫1头。标记释放点至回收点直线距离为725~1 117 km。这是迄今为止世界上确认的草地螟最远迁飞距离。这些证据不仅证实了我国越冬代草地螟成虫能从华北迁往东北危害, 而且为进一步了解草地螟的种群动态规律, 改善草地螟的预测预报技术提供了重要的科学依据。

关 键 词:草地螟    迁飞    标记释放回收    迁飞距离    迁飞路线    越冬区

Abstract:A mark-release-recapture (MRR) experiment was conducted in June, 2009 in Inner Mongolia Autonomous Region, and the peak for the overwintering adult population of the beet webworm, Loxostege sticticalis L. (Lepidoptera: Pyralidae) was detected in order to demonstrate the migratory pathway and capacity of this species from northern region to northeast region in China. In July, about 1.8 million adults were caught by nets, marked by spraying colorant and released at 6 sites distributed in Wuchuan County (41.07°N, 111.42°E) and Chayouzhongqi (41.13°N, 112.58°E) of Inner Mongolia during June 1st-4th, 2009. At the monitoring and forecasting units of the beet webworm at various levels in the 11 main occurrence provinces or autonomous regions in northern China, methods such as trap lamps, clap nets and pheromone traps were used to recapture the adults of this moth. Nine adults, released at Chayouzhongqi, were recaptured at Keyouzhongqi, Wulanhaote, and Zhalantun County, respectively, in northeastern Inner Mongolia during June 7th-25th, and 1 adult released at Wuchuan County was recaptured at Beipiao County of Liaoning Province on June 29th. The straight distances from the released sites to the recaptured sites were from 725-1 117 km. This is the longest distance taken by the migratory flight of the beet webworm that has been recorded in the world. These results not only prove the soundness of traditional assumption that the beet webworm originated from northern China is one of the sources for the 1st generation of the moth in northeastern China, but also provide important basis to improve the forecast and management technology of the beet webworm.
Keywords:Loxostege sticticalis  migration  mark-release-recapture (MRR)  migration distance  migration route  overwintering areas
