The Identification of Biotypes of Bemisia tabaci in Shanghai Area
摘要
Abstract
The Bemisia tabaci (Cennadius) species complex is one of the most devastating agricultural pests in the world, which is composed of numerous bieiypes. These biotypes show different biological traits with respect to host range,virus -transmission capabilities and insecticide resistance. In this study, the 45 Bemisia tabaci populations from 10 different regions of Shanghai were collected and analyzed based on the gene sequence of Mitochondrial cytochrome oxidase 1 ( mtDNA COI). The results show that the populations from Jiading, Jinshan and Xuhui districts were only Q biotype, and only B biotypes was found in Minhang district, but B and Q biotypes co - exist in other districts. Moreover, among the total 45 populations of Bemisia tabaci i-dentified in this study, 31 populations were Q biotype, 68. 9% proportion and B biotype 31. 1% respectively. In addition, most populations collected from greenhouse were Q biotype(87. 0% ). The results indicated that Q biotype spreads widely in Shanghai area and may replace the B biotype as a major crop pest in Shanghai area.关键词
