Abstract: DNA barcoding which is based on molecular biology and bioinformatics is a new method for biology Taxonomy. It has been applied widely for species identification due to its quickness and accuracy. The task for insect species identification is difficult and complex owing to a wide variety of insects. Therefore, DNA barcoding could be an efficient method to identify insects. This paper briefly introduced the conception, principles, and operations of DNA barcoding, and reviewed the application of DNA barcoding in insect taxonomy, as well as the advantage and limitation of the method compared with traditional morphological classification methods. At the same time, the paper also discussed the feasibility of barcoding in insect taxonomy and its development prospect.
