ABSTRACT
Objective To identify the species of sarcosaphagous flies by amplifying cytochrome oxidase subunitI (CO I) gene fragment,combined with morphological characteristics.Methods The DNA of sarcosaphagous flies was extacted by modified Tris balanced phenol-Tris saturated phenol protocol,the amplificationand sequencing of CO Ⅰ fragment were conducted,and the results were then compared with the database for analysis.Results The modified DNA extration method by Tris balanced phenol-Tris saturated phenol could obtain effective DNA of sarcosaphagous flies,and be applied for CO Ⅰ fragment amplification,and thus for identification of the species of sarcosaphagous flies.Conclusion The DNA extracted from sarcosaphagous flies by modified Tris balanced phenol-Tris saturated phenol protocol could be used astemplate for the amplification of CO Ⅰ fragment,and the system could identify the species of sareosaphagous flies after sequencing and alignment with the sequences of database.Compared with traditional identification methods of using morphological characteristics,the current system is more accurate and could be more widely applied.
