Genetic characterization, population genetics and demographics history of Bactrocera Zonata (Saunders) (Tephritidae: Diptera) of cox1 gene

Background: (1) Bactrocera zonata (Saunders) (Tephritidae : Diptera) , is one of destructive and invasive fruit fly species of the genus Bactrocera . In the present study, genetic structure, genetic diversity and demographic history of B.zonata was inferred from cytochrome oxidase I (cox1) gene sequence; (2) Methods: Analysis of similarity test shows in DNA barcode with 100% accurate identification of B.zonata specimen which was differentiated from other Bactrocera species; (3)Result: Descriptive statistic analysis of B.zonata revealed high genetic diversity through the indices [number of haplotypes (H), haplotype diversity (Hd), nucleotide diversity (p) and average number of nucleotide differences (k)]. Negative values of Tajima’s D and Fu’s Fs and star-like network of haplotypes inferred neutrality; (4)Conclusion: 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.
