| Abstract: | DNA barcoding is a kind of new method using mtDNA to identify of species,and is also the basis of biological fast identification,classification,phylogeny and evolution analysis.In this study,parts of COI gene in 6 species 4 genera 2 tribes of Tachininae(Diptera,Tachinidae) from Liaoning Province,China were amplified and sequenced.The sequences of COI were analyzed and phylogenetic trees of those species were constructed by use of MEGA4 software.The result revealed that DNA barcoding is consistent with morph... |
