烟粉虱Bemisia tabaci是一个复合种,它具有的生物型分化、较强的传播病毒的能力和抗药性、较快的繁殖速率等特征使其成为我国农业生产中重要害虫之一.本研究利用细胞色素线粒体氧化酶I基因,对采集自江苏、广东和云南三省的烟粉虱样本进行了生物型鉴定,并对烟粉虱生物型与寄主植物之间的关联性开展了调查.结果表明,在广东和云南省,都存在未鉴定的土著种群与入侵的B型、Q型共存的现象;同时,在本研究中广东省尚未采集到Q型烟粉虱,而在江苏采集到的粉虱样本全部为人侵型.研究结果还表明,相对于入侵种而言,土著种群显示出更强的寄主植物趋同性;丰富的寄主植物以及本身具有的多食性特性有助于B型、Q型等生物型在世界各地的广泛入侵.

The sweetpotato whitefly,Bemisia tabaci(Gennadius),is a species complex that is considered an important agricultural pest because of its diversity in biotypes,capacity to transmit viruses,high resistance to chemicals and rapid physiological development.Its biotype status in Jiangsu,Guangdong and Yunnan provinces was determined by using mitochondrial DNA Col markers and correlated with their host plants and locations.Results indicated that.in Guangdong and Yunnan,the local unresolved biotypes and the already known biotypes 0f B.tabaci(B and O)coexist the fc'rnler is relatively more dependent on its host plants than the invasive biotypes.No Q biotype of B.tabaci has been found in Guangdong and no local biotype has been found in Jiangsu in this studv.Multitudinous host plants and the inherent polyphagous characteristics enhance the wide invasion of B and Q biotypes in different counties.
