【摘要】 烟粉虱Bemisia tabaci(Gennadius)是一种重要的农业害虫,并含有许多生物型。其中,烟粉虱Q型和B型是目前研究最为广泛深入的两种生物型。近20年来,烟粉虱B型传入世界各地并暴发成灾,被视为入侵性最强的生物型。相对于烟粉虱B型,烟粉虱Q型是近年来引起人们高度重视的一种新的生物型。在介绍烟粉虱Q型与B型系统发育关系以及基因交流的基础上,着重论述这两种生物型的种群动态及其影响因子的研究进展,以期揭示烟粉虱Q型与B型的成功入侵机制,并为其控制提供依据。更多还原

【Abstract】 Bemisia tabaci(Gennadius)is an important agricultural insect pest and comprises numerous biotypes.Biotypes Q and B are most well-studied biotypes among them.The biotype B has invaded many countries and regions and erupted worldwide during the last 20 years and was considered as the most invasive biotype.Compared to biotype B,biotype Q has been a new harmful biotype during the recent years.On the basis of introduction of the phylogenetic relationship and gene flow between biotypes Q and B of B.tabaci,the population dynamics of the two biotypes and the influential factors were introduced.The purpose of the review was to explore the invasion mechanism so that the reference information of the two invasive biotypes was provided to help their control.更多还原
