摘  要:
迁飞是昆虫区域性灾变的重要因素之一,阐明昆虫在空中的运动过程对发展迁飞害虫预警体系有重要意义。昆虫空中运行过程由起飞、运转和降落三个阶段组成,近年来的研究证实多种昆虫具有主动定向的能力,迁飞过程中的共同定向行为决定平均位移速度、迁飞轨迹和降落区域。昆虫的定向机制包括太阳罗盘定向、地磁定向、星空标志定向、偏振光定向、对风漂移的补偿和风定向等。

摘  要:
Migration is one of the most important factors that affect regional disasters of insects,and the knowledge on aerial movement of insects plays an important role in establishing the alarm system of migratory insect pests.The aerial flight process roughly consists of three stages: taking-off,navigation and landing.The investigations in recent years indicated that many insects possess the ability of orientation during migration process,which determines their displacement speed,migratory trajectory and landing location.Insect orientation mechanisms mainly include sun compass,magnetic compass,celestial cues,polarized light,compensation for wind drifts and wind orientation.
