烟粉虱传播的植物病毒病及其化学防治研究进展

烟粉虱是一种世界性重大害虫,传播植物病毒病,严重危害农林业生产。烟粉虱可以传播400多种植物病毒,主要包括双生病毒科Geminiviridae的菜豆金色花叶病毒属Begomovirus、长线病毒科Closteroviridae的毛病毒属Crinivirus、乙型线状病毒科Betaflexiviridae的香石竹潜隐病毒属Carlavirus和马铃薯Y病毒科Potyviridae的甘薯病毒属Ipomovirus。其中,菜豆金色花叶病毒Begomovirus是烟粉虱传播的主要病毒,在所传播的病毒中约占90%。治虫防病是控制此类病毒病的主要方法,双酰胺类及新烟碱类等杀虫剂是目前防治烟粉虱的主要药剂。目前生产中虽然还缺乏对病毒病高效的化学药剂,但抗病毒药剂的研发受到人们的广泛关注。通过对烟粉虱传播的病毒病类型,以及治虫防病的化学药剂进行综述,期望为烟粉虱及其传播的病毒病防控提供思路。

Research Progress of Plant Virus Disease Transmitted by Bemisia tabaci and Chemical Control

Bemisia tabaci is a major worldwide pest that spreads plant virus diseases and seriously harms agricultural and forestry production. B. tabaci can transmit more than 400 plant viruses, mainly including Begomovirus of the family Geminiviridae, Crinivirus of the family Closteroviridae, Carlavirus of the family Betaflexiviridae and Ipomovirus of the family Potyviridae. Among them, Begomovirus is the main virus transmitted by B. tabaci, which accounts for about 90% of the transmitted viruses. Insect control is the main method to control such virus diseases. The main insecticides to control B. tabaci are bisamides and new nicotine. At present, although there is a lack of effective chemical agents for virus diseases, the research and development of antiviral agents has attracted wide attention. The types of virus diseases transmitted by B. tabaci and the chemical agents for pest and disease control were reviewed in order to provide ideas for the prevention and control of B. tabaci and its transmitted virus diseases.
