Abstract：Fleas are not only important medical insects, but important propagation media of plague which is legal category A infectious disease in China. There are more than 2,500 species of fleas in the world, and they are rich in genetic diversity. Genetic diversity can not only reveal the genetic variation and system evolution and clear some problems of morphological classification, but provide an important scientific basis for the control and prevention of insect-borne infectious diseases as well. This paper reviews the application of molecular biology technologies (RAPD, SSR, SNP, GWAS, rDNA and mtDNA) to research on the genetic diversity of fleas.
