Abstract:

Objective To investigate the species and distribution of fleas in the frontier ports of China. Methods The fleas were collected from the rodents captured by snap-trap and live-trap, during the period from 2001 to 2015. Results The fleas were identified as 113 species or subspecies, belonging to 6 families, and 28 genera. Due to the complex habitats, the northern port areas have large variety of host rodents and the fleas. The fleas in the Xinjiang port areas possess the most diversity, reaching 57 species and subspecies, among which, 29 species occurring in Alashankou port. Closely followed were Inner Mongolia port areas, including 24 species in Erlianhaote port, then Heilongjiang port areas, including 19 species in Suifenhe port area. For the habitats of the southern port areas are monotonous, and the common host animals were commensal rodents,the species of fleas were less. Only 1-2 species were captured at most of those ports. Conclusion The species and distribution of fleas in the important frontier ports of China were studied, which provided the basic data for the prediction, risk analysis and prevention and control of flea borne diseases at frontier ports in the whole country.
