Abstract:

  【Abstract】 Objective To understand the population composition and seasonal fluctuation of fleas parasitized on Rattus tanezumi in Leizhou city. Methods R.tanezumi were captured in selected districts of Leizhou city from 1985 to 2004. Fleas were collected from their body surface and identified to count the flea index and its  composition  proportion.  Results A total of  1721 R.tanezumi were caught, and about 2345 fleas belonged to 4 species were collected. Among them, Xenopsylla cheopis and Leplopsylla segnis were the dominant species, the average index of them were 1.24 and 0.12, and the proportion of them were 91.13% and 8.66%, respectively. The index and composition proportion of  Pulex irritans and Ctenocephalides felis felis were very low. Conclusion R.tanezumi was the dominant host of X.cheopis and L.segnis. The number of X.cheopis increased year by year, but that of L.segnis decreased year after year.
