The peach fruit fly, Bactrocera zonata, is among the most serious and polyphagous insect pest of fruit
crops in many parts of the world under genus Bactrocera. In the present study, the genetic structure,
diversity and demographic history of B. zonata in India were inferred from mitochondrial cytochrome
oxidase 1 (cox1) and NADH dehydrogenase 1 (nad1) sequences. The efficiency of DNA barcodes for identification
of B. zonata was also tested. Genetic diversity indices [number of haplotypes (H), haplotype
diversity (Hd), nucleotide diversity (p) and average number of nucleotide differences (k)] of B. zonata
populations across India maintain high level of genetic diversity without isolation by distance among
the geographic regions. Non-significant negative correlation between pairwise Fst and geographic distance
suggests a high level of gene flow among studied populations of B. zonata. The possibility of
sudden expansion of B. zonata revealed through mismatch distribution analysis as well as negative
Tajima’s D and Fu’s Fs values further supported by star-like network of haplotypes. DNA barcoding analysis
suggests that B. zonata specimens can be clearly differentiated from other species with 100%
accuracy of identification. Therefore, cytochrome oxidase 1 (cox1) barcode sequences generated in the
present study could be a valuable source for the rapid identification and global population genetic
study of B. zonata.
