近10年我国烟粉虱发生为害及防治研究进展

烟粉虱是我国重要农业害虫,近10年来我国烟粉虱发生为害呈现以下特点:烟粉虱的优势生物型/隐种由B型更替为Q型;传播植物病毒(如黄化曲叶病毒、番茄褪绿病毒)成为了烟粉虱重要的为害方式;烟粉虱抗药性问题逐渐突出;化学农药尤其新烟碱类杀虫剂的广泛使用是Q型烟粉虱取代B型烟粉虱的关键因素。烟粉虱的综合防控措施日益完善,抗药性治理与非化学防控措施受到重视,但是依靠农药的现状并未完全改变。本文综述了近10年来我国烟粉虱的发生为害及防治方面的概况,探讨了今后烟粉虱防控方面的研究内容。

Research progress on the damages and management of Bemisia tabaci (Gennadius) in China over the past 10 years

The sweetpotato whitefly, Bemisia tabaci (Gennadius), is an important insect pest in crops. Over the past 10 years, B.tabaci has been researched extensively and intensively in China. The dominant biotype of this pest in most area of China has changed from biotype B to biotype Q during this period; the transmission of plant viruses such as Tomato yellow leaf curl virus (TYLCV) and Tomato chlorosis virus (ToCV) has been the important damage mode of B.tabaci; the insecticide resistance problem of B.tabaci gradually occurred in many regions; the application of insecticides, especially neonicotinoids, is the key factor involved in the displacement of B biotype by Q biotype of B.tabaci. The measures in the integrated management of this pest have been supplemented, among which the non-chemical measures have been emphasized. However, the control of this pest still depended mainly on the application of insecticides in most regions. This paper reviewed the research progress on the damages and management of B.tabaci in China over the past 10 years and discussed the future research in the management of this pest.
