Objective: To characterize the biological characteristics of natural vectors of Yersinia (Y.) pestis in China.
Methods: Species and genera of natural vectors of Y. pestis in China and their faunal distribution were characterized with modern insect taxonomic techniques. The ecological roles of natural vectors of Y. pestis in natural plague foci were determined according to insect ecological experiments.
Results: There were 63 species of natural vectors of Y. pestis including 28 major reservoirs and 35 secondary ones.
Conclusion: The biology characteristics of major vectors on Y. pestis and their roles in natural plague foci were defined.
