[Abstract]:Objective to explore a molecular phylogenetic method for identification of necrophilic flies in forensic medicine. Methods Mitochondrial DNA (mtDNA) Cytb and ND1 gene were amplified by PCR, polyacrylamide gel electrophoresis (page) silver staining was used to type the genotypes, DNA genetic analyzer was used to sequence the typing products, and the sequence was analyzed by systematic chemical software and statistical method. A method for species identification of necrophilic flies in forensic medicine was established. Results the mtDNA Cytb and ND1 genes of 6 species of necrophilic flies in three regions of China were amplified, electrophoretic and sequenced. The phylogenetic relationship of these necrophagous flies was established, and the method of identifying the species of coriophilic flies by forensic medicine was preliminarily established in combination with the results of phylochemical analysis. Conclusion based on mtDNA Cytb and ND1 genes, a molecular phylogenetic method for identification of species of necrophilic flies was established.
