草地螟 meaning in English
loxostege sticticalis; meadow webworm (也叫“黄缘条螟”, 杂食性害虫)
Examples
- 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。 - The ground based light - trap caught large numbers of l . sticticalis on the next evening , after an immigration event , so priority of catching peaks in searchlight trap to ground based light - trap was a good indication of migration
草地螟迁入后第二晚地面灯诱虫器诱到大量蛾子，故探照灯诱虫器诱虫高峰早于地面灯诱虫器一天可作为草地螟迁入的一个良好的指示。 - Ovary development stage of females in catches and radar observation indicated that l . sticticalis migrated to northeast in early june , to southwest in august and september , and locally - bred moths dispersed over shorter distances in july and august
卵巢发育进度法和雷达观测表明草地螟在6月初向东北迁飞，在8月和9月向西南迁飞，当地繁殖的蛾子在7 、 8月份进行短距离扩散。 - 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。
