Abstract

Comparative assessment of the mitochondrial cytochrome oxidase I (mtCOI) gene sequence uncovers the Bemisia tabaci mitotypes. The current study aims to define B. tabaci mitotypes found in various agro ecological zones across India. Phylogenetic analysis of 13 samples from various agroclimatic regions revealed presence of four mitotypes: Asia 1, Asia II 1, Asia II 5 and Asia II 7. Among, Asia II 1 was found to be abundant and widespread distribution in the thirteen locations studied. From the 13 sequences examined, 7 haplotypes viz., three of Asia II 1, two of Asia II 5, each one of Asia 1 and Asia II 7 were identified. Nucleotide diversity was observed to be greater in Asia II 5 (0.00388) than in Asia II 1 (0.00258), and haplotype diversity was observed to be greater in Asia II 5 (1.000) than in Asia II 1 (0.600).
