Abstract

Recently many forensic scientists are trying to use the DNA 'barcode' region (upstream portion of mitochondrial cytochrome oxidase subunit I) to identify the species of forensically important fly species. We have analyzed to compare their sequences of the 'barcode' region for twelve blow fly species[A. grahami, C.lata, C. vicina, H.ligurriens, L. ampullaceal, L. Caesar, L. illustris, P. sericata, P. regina, T. calliphoroides, C. megacephala, C. pinguis] collected from the rural and urban regions in Korea. Intra- and interspecies sequence divergences were calculated as 0~0.9% and 0.9~11.4%, respectively. Phylogenetic trees were drawn with Mega 3.1 and Network 4.20 programs. The result illustrates that each genus is grouped as monophyletic group except for T. calliphoroides and all the same species were monophyletic group. This suggests that the 'Barcode' region of COI gene could be a marker for identification of necrophagous blow fly species. But the two closely related species, L.illustris and L.caesar show little differences from each other. Therefore more individuals of these species should be examined for population study.
