| 摘 要： | 1999年9－10月利用昆虫雷达对华北地区昆虫秋季回迁的观测表明，秋季迁飞主要发生于19：00－05：00时，飞行高度一般在300－2000m。迁飞方向与风向一致，多为从东北向西南方向迁飞。运行速度和飞行高度成正相关，迁飞个体的平均运行速度由392m高度的4.8m/s增加到2000m处的27.8m/s。空中灯光诱捕表明，甜菜夜蛾和棉铃虫为优势迁飞种类。

| Abstract: | Flight and migration are important activities in the life cycles of many insect pests.Most insects can move several kilometers in one night even without wind assistance.If the insects climb to altitudes above the planetary boundary layer to gain wind assistance,they can indeed travel long distances during one or more nights.The capability of some insects to take long distance migration makes them potentially access to their favorable habitats for feeding and breeding,which become a major factor that insect ... |
