甘薯粉虱Bemisia tabaci（Gennadius）（半翅目：粉虱科）对许多作物造成严重的作物损失。这些损失中最严重的往往与该害虫生物型B和Q的入侵和建立有关。2007年的研究表明，Q型在中国大部分野外种群中与其他生物型共存。为了确定该领域的生物型组成的现状，2009年进行了广泛的调查，主要覆盖中国东部地区。利用线粒体细胞色素氧化酶I生物型B和Q的特异性引物和基因测序技术，对我国19个省、自治区61个粉虱种群的生物型组成及其分布进行了研究。2009年在我国仅发现生物型B和Q。其中，Q型占优势的有44个（100.0%），B型占优势的有17个（100.0%）。目前的调查表明，在中国大部分地区，Q型已迅速取代B型。
The sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), causes severe crop losses to many crops. The worst of these losses are often associated with the invasion and establishment of biotypes B and Q of this pest. Previous research in 2007 showed that biotype Q occurred with other biotypes in most field populations in China. To determine the current status of the biotype composition in the field, an extensive survey covering mainly eastern parts of China was conducted in 2009. Using polymerase chain reaction primers specific for the mitochondrial cytochrome oxidase I of biotypes B and Q and gene sequencing, we determined the biotypes composition in 61 whitefly populations and their distribution across 19 provinces in China. Our research revealed that only biotypes B and Q have been found in the field in 2009 in China. Among them, biotype Q was dominant in 44 locations (100.0%) and biotype B was dominant in 17 locations (100.0%). The current survey indicates that biotype Q has rapidly displaced biotype B in most locations in China.
