Objective To optimize the method for the extraction of mosquito mitochondrial genome DNA. Methods The optimized method was improved from the protocol for the extraction of animal mitochondrial genomes, and was based on the modification for high-concentration-salt precipitation and nuclear DNA removing. The mtDNA samples were tested using spectrophotometry, agarose gel electrophoresis and amplification products of COⅠ. Results The method was showed to be rapid and efficient for single mosquito in our studies. The gel electrophoresis demonstrated that the mtDNA samples extracted were essentially free of nuclear DNA and protein. A number of applications with different mosquito species indicated that the method was highly suitable to extract the mitochondrial genome DNA of individual mosquitoes. Conclusion The optimized method is easy and efficient for mosquito samples, and the extracted mtDNA is high quality and suitable to studies on mitochondrial DNA.
