ABSTRACT
It is an important topic that the plague vector efficiency has been studied in plague epidemiology from the plague found out,and it is one of the key issues that we recognized the plague preservation and prevalence in nature ecological system too.Current related biological basis,technical theory and new technology research and application,and other fields have made important achievements and progress in the study of plague vector efficiency,but a systematic and standardized evaluation of vector competency and efficiency is needed in modem vector transmission plague research.It is,therefore,necessary to establish specific and valid research indicators based on the plague natural ecological system and the plague nature quality and specific scientific research purpose,and these indicators will also be able to serve the research goal,improve the credibility and comparability of vector efficiency of research results.
