摘要
B型烟粉虱是近二十年来入侵世界各国并暴发成灾的一种世界性重要害虫。近年来 ,B型烟粉虱的入侵机制研究表明 ,其成功定殖、扩散、暴发与其对入侵地区的土著烟粉虱种群和其它昆虫种群的竞争取代有关 ;竞争取代包括生态位竞争 ,生殖干涉 ,其危害寄主对其它昆虫的影响等方面。B型烟粉虱抗药性的形成也是这种生物成功入侵的重要影响因素。同时 ,生态环境 (包括寄主植物、气候因子、越冬场所等 )的影响也不容忽视。最后本文还探讨了B型烟粉虱入侵机制研究动态及其意义。
Bemisia tabaci (Gennadius) biotype B is an important pest that have outbreaked and caused severe damage worldwide through the last 20 years. Recent progress in studying mechanisms of its invasion indicates the greater ability of competitive displacement which involves the competition of ecological niche, reproductive interference, the interactions of whitefly and virus with indigenous B. tabaci and other competing herbivores, is the most important factor. The successful invasion and rapid spread is affected by the pesticide resistance. In the meantime, the ecological environment (such as host, climatic factor, overwintering sites) also affected the invasion of B. tabaci biotype B. Finally the importance of the invasive mechanism of B. tabaci biotype B and potential directions for future research are discussed.
