- The long distance high - altitude wind - borne migration of the beet webworm moths l . sticticalis and short distance dispersal were observed in 2001 and 2002
2001和2002年观测到了草地螟高空远距离的风载迁飞和短距离扩散。 - It was the first trial to employ the newly equipped migration data acquisition and analysis system for the scanning entomological radar and , a twin light - trap developed in china for , systematic long - term observations of migration of the beet armyworm spodoptera exigua , beet webworm loxostege sticticalis and cotton bollworm helicoverpa armigera in northern china the study provided direct evidence for the migration of 5 " . exigua in china , many parameters of migratory behaviour of the three species of insects , a better understanding of the relationship between migratory behaviour and wind or temperature field . the results enriched the theory of migration and provided new scientific knowledge for pest management in china
本研究初步阐明了我国华北地区空中昆虫群落结构，首次使用我国自行研制的扫描昆虫雷达的数字化数据采集及分析系统，及价廉、高效的姊妹灯诱虫法对华北地区甜菜夜蛾spodopteraexigua 、草地螟loxostegesticticalis和棉铃虫helicoverpaarmigera的迁飞进行了长期系统地观测，得到了甜菜夜蛾在我国北方迁飞的直接证据，三种害虫迁飞行为的若干参数，认识了昆虫迁飞行为与风温场的关系，丰富了昆虫迁飞理论，为我国害虫的治理提供了科学依据。
