X. cheopis and L. segins are the main surface parasitic fleas of the main host animals, Rattus flavipectus, in the plague foci of Yunnan, Yersinia pestis is isolated. According to the experimental study of the media efficacy of two species of fleas, the characteristics of ecological biology and the prevalence of plague in recent years, it is believed that the rat flea is the main transmission medium for the rat plague, and the slow flea is not
