Demographic Expansion of the Predominant Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) Mitotypes Associated With the Cotton Leaf Curl Virus Epidemic in Pakistan

The association between Bemisia tabaci mitotypes and cotton leaf curl outbreaks in Pakistan was investigated using the mitochondria cytochrome oxidase I gene (COI) as a molecular marker. The 3′-651 base fragment has been used to resolve B. tabaci phylogenies. However, the 5′-618 base fragment was nearly unexplored. Phylogenetic analysis for 829 whiteflies from 11 districts in two provinces of Pakistan, indicated all haplotypes grouped on the...
