蚜虫迁飞的研究进展

Advance in the studies of migration of aphids

蚜虫的迁飞能造成危害扩展、病毒病传播和防碍人们的正常生活。蚜虫迁飞有其生理生态基础。寄主营养、蚜群拥挤度、天敌以及气候条件是刺激有翅蚜产生的主因素。蚜虫迁飞与卵巢发育存在明显的共轭关系。蚜虫迁飞多发生在晴朗的白天 ,并且温度、光照和风是影响迁飞行为的主导因子。蚜虫可上升到逆温层并随气流迁飞到上百公里以外的地方。目前 ,昆虫雷达观察、天气学分析和分子生物学方法已应用于蚜虫迁学的研究中 ,文章对蚜虫迁飞的生理生态基础、迁飞行为、影响迁飞的生态因子以及研究方法进行了综述 。

The migration of aphids would cause the crop's damage extension,virus diseases spreading and distrubance of our live.The ecological and physiological bases of aphid's migration were found.The host nutrients,crowding,enemies and climate were the main factors of the production of alatae aphid.There was a negative relationship between ovary development and imgration behaviour.The migration behaviour usually occurred in the daytime,and the temperature,light and wind were the main influence factors.The migratory aphids could asend to the height of inversion layer of air and migrate hundreds kilometers.Recently,the insect radar detection,climate analysis and molecular methods were used on the migration of aphids.The physiological and ecological base,migration behaviour,influence factors and the study methods of aphid migration are reviewed.
