Fruit flies under Tephritidae are one of the diverse and agriculturally important insects. It needs reliable taxonomic procedures to resolve species complexes and genetic structure analysis to effectively control this pest. Little attention has been given to the analysis of genetic diversity in South Indian populations. By using mitochondrial cytochrome oxidase I and II (cox1 and cox2), the genetic analysis of B. dorsalis from eight locations of major fruit growing areas in western parts of Tamil Nadu were investigated. Genetic diversity indices such as a number of haplotypes (H), haplotype diversity (Hd), nucleotide diversity (π), and the average number of nucleotide differences between sequences (k) of the populations revealed that Bactrocera dorsalis has a high level of genetic diversity with distinct genetic structure. Future studies should concentrate on extensive sampling from varied geographical locations of south India along with complete species delimitation, and also microsatellite marker analysis which would enable us to understand the complete genetic and population structure of this pest. This information will be useful to devise an area-wide management programme for this destructive pest.
