摘　　要：利用烟粉虱[Bemisia tabaci(Gennadius)]B生物型和Q生物型mtDNA COⅠ基因片段的特异性引物及烟粉虱mtDNA COⅠ基因片段通用引物,对2009年采自北京市海淀区、昌平区和河北廊坊市的蔬菜所3个基地的烟粉虱种群的生物型进行了鉴定,同时以本实验室在温室内长期饲养的B型烟粉虱种群作为对照。结果表明,2009年在3个地区所采集的烟粉虱全部为Q型,而在2004年这3个基地发生为害的烟粉虱全部为B型,表明Q型烟粉虱已经取代了B型烟粉虱在这些地区发生为害。An extensive survey of Bernisia tabaci populations covering 3 areas in and around Beijing was conducted in 2004 and 2009 in order to define the biotype status of the pest. Sampling was done both on protected and out- door cultivations of vegetables. Biotype identification was performed using molecular diagnostics based on the mitochondrial cytochrome oxydase I gene of biotype-specific primers and universal primers. The results indicated the presence of only the biotype Q in 2009, but only biotype B in 2004, showing the B biotype B. tabaei was replaced by Q biotype B. tabaci in these areas.
