Abstract: Objective To study the behavior of Nosopsyllus wualis laizhouensis and Acropsylla episema girshami biting and sucking human blood,to provide evidence for evaluting the significance of N.w.laizhouensis and A.e.girshami in plague disease epidemiology. Methods Fix fleas fixed on volunteer's antebrachium and crus,to bite and suck freely. Results The sucking rate of N.w.laizhouensis is 63.48%,there were no significan differences among the sex of flea,man's age,man's blood type and position of biting. The sucking rate of A.e.girshami is 11.71%,the selectivity on man's blood type and position of biting was found in our study. Conclusion They all can bite and suck man's blood. The biting and sucking blood ability for N.w.laizhouensis is stronger than for A.e.girshami,and both of them are great significance in plague epidemiology.
