摘 要：
为了解北京地区甜菜白带野螟的种群动态和虫源性质,于2013年在北京延庆利用探照灯诱虫器对甜菜白带野螟成虫开展了逐日监测,并进行了统计分析。结果表明,北京延庆仅见1代成虫,主要出现9月份,且雄虫明显多于雌虫。分时段数据显示,甜菜白带野螟可整夜扑灯,9月19日数据符合迁入种群特征。风场分析表明,成虫数量变化与风向密切相关。上述证据表明,2013年北京延庆诱集的甜菜白带野螟成虫属于迁飞性种群。

摘 要：
In order to discover population dynamics of Spoladea recurvalis Fabricius and related migration possibility,surveys were carried out in Yanqing district of Beijing with search light trap in 2013. The results showed that there was only1 generation of S. recurvalis which mainly occurred in September, and the male was significantly more than the female.Section samples data showed that S. recurvalis can be trapped in whole night and data of 19 thSeptember was in line with characteristics of migratory insect species. Wind field analysis showed population dynamics was closely related to wind direction. In conclusion, S. recurvalis caught in Yanqing in 2013 belonged to migratory population from the above evidences.
