摘　　要： 烟粉虱具有较强的飞行潜力,飞行高度可以超过150m,在田间的扩散距离最远可以超过7km,但在食源丰富地区,较少作远距离的扩散,绝大部分飞行高度在距地面0.5m左右.烟粉虱具有搜索飞行和迁飞飞行特性,它是寻找适宜寄主和扩大生境的重要方式.烟粉虱不具备“卵子发生与飞行共轭”的典型特征.可见光、温湿度、寄主质量和风等是影响烟粉虱飞行行为的重要生态因子.本文对烟粉虱的飞行能力、飞行生理学和影响飞行的生态因子进行了综述,对非露地越冬区利用烟粉虱的飞行特性实施IPM策略进行了探讨. Bemisia tabaci, a pest insect with stronger capabilities of flying and host plant-exploitation, is capable of flying 150 m high and over a distance as far as 7 km, but hardly flies higher than 0.5 m and long distance in food-abundant areas. B. tabaci has the characteristics of both searchingand migrating flying, which enable it to exploit and locate on suitable hosts. Up to now, no oogenesis-flight syndrome of B. tabaci has been detected. Visual spectrum, air temperature and relative humidity, host quality, and wind speed are the main factors affecting the flight behavior of B. tabaci. In this paper, the flying capability of B. tabaci and the factors affecting its flight behavior were summarized, and the corresponding IPM strategies in the areas where B. tabaci could not overwintering in open field were discussed.
