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.
