The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a phloem–feeding, economically important pest of crops worldwide. In addition to direct damage, it also vectors a number of plant viruses belonging to the family Geminiviridae. Its populations differ biologically with respect to insecticide resistance, virus transmission and host range. Therefore, understanding genetic variation among populations is important for management.. Barcoding Of Whitefly

We sequenced 850 bp of the mitochondrial COI(mtCOI) gene from B. tabaci populations surveyed across India. BLAST analysis of the mtCOIsequences generated in this study with sequences from the mtCOI dataset showed the presence of one of the biotypes of whitefly
