Abstract: Mitochondrial cytochrome oxidaseⅠ(mt COⅠ) (~830 bp) gene sequences were utilized as markers to identify biotypes of 5 populations of Bemisia tabaci in China. Of the 720 characters examined for COⅠsequences, only 2 bases exhibited divergence and overall similarity was 99.7%. Examination of 423 characters in populations from Xi'an and Tulufan revealed that these two populations were of the same haplotype as AZB3. The results indicated that all 5 populations were of the B-biotype.

Key words: Bemisia tabaci, PCR, mtDNA, COⅠ sequence, biotype
