Objective To characterize the biological characteristics of natural vectors of Yesinia (Y.) pestis in China.Methods Species and genera of natural vectors of Y.pestis in China and their faunal distribution were characterized with modem 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.

Objective To group and characterize natural plague foci in China.Methods A novel two-class typing method as well as a three-indication nomenclature method were established to group and characterize the natural plague foci,on the basis of eco-geographical landscapes of plague foci,genetics of Yersinia pestis,zoology of rodent reservoirs and the entomology of flea vectors.Results A total of 12 distinct natural plague foci (including 19 subtypes) as well as their biological features were characterized.Conclusion Natural plague foci in China were grouped and characterized in this study.
