摘    要:烟粉虱是一种危害严重的世界性害虫,是一个快速进化的复合种.本文利用mtCOI分子标记方法,对2010和2011年采自我国9个省(市)的33个烟粉虱种群进行了生物型鉴定和系统发育分析.结果表明: 我国目前存在着B型、Q型、ZHJ-1型、ZHJ-3型、An型以及Nauru型等6种生物型,且不同生物型的分布是不均匀的.遗传距离及系统发育树的分析结果显示,海南省的An型和台湾省的An型聚为一支,为同一来源;中国B型与来自法国和乌干达的B型的亲缘关系较近,同源性达到99%以上;中国的Q型与来自摩洛哥和法国的Q型聚为一个分支,而来自以色列和土耳其的Q型烟粉虱单独聚为一支,说明中国的Q型烟粉虱与来自地中海西部的Q型烟粉虱亲缘关系更近,可以推断中国的Q型烟粉虱的起源地为地中海西部地区.

Abstract:Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae) is considered taxonomically as a species complex and could cause serious damages to crops by directly feeding on phloem and/or indirectly transmission of plant viruses. In this study, biotypes and phylogenetic relationships of 33 geographic populations of B. tabaci collected from nine provinces of China in 2010 and 2011 were studied based on the mitochondrial COI gene. The results showed there were a total of six biotypes of B. tabaci (B, Q, ZHJ-1, ZHJ-3, An and Nauru) recovered in China and the geographical distribution of these six biotypes was uneven. Phylogenetic analysis showed that biotype An B. tabaci from Taiwan clustered together with Hainan biotype An populations, indicating these two geographic populations might originate from a same ancestor. In addition, biotype B B. tabaci in China had a 99% genetical similarity compared to that from France and Uganda. However, relationships of biotype Q on the phylogenetic tree were divided into two different clusters. One was occupied with the population from China and Western Mediterranean Sea countries (France and Morocco) and the other contained biotype Q populations from Eastern Mediterranean Sea countries (Israel and Turkey). Overall, the results suggested that biotype Q B. tabaci in China was genetically similar to that from Western Mediterranean Sea countries and it could be highly possible that Chinese biotype Q B. tabaci originated from Western Mediterranean Sea areas.
Keywords:Bemisia tabaci  biotypes  mtDNA COI  genetic distance  phylogenesis
