Objective To master the background of fleas and mites at Changchun Longjia International Airport so as to provide a scientific basis to prevent and control vector- borne diseases. Methods From July 2010 to June 2011, the live rats were captured by the cage method. The fleas and mites carried on the surface of rats were ana- lyzed, classified and identified by flea collection method and rats＇body mite index method. Results 62 rats were captured and the rate of fleas infected rats was 20.97%. 30 Fleas were captured, belonging to five types, in which Ctenophthalmus congeneroides congeneroides was the dominant species, with a composition ratio of 50.0%. 70 mites were captured, in which Laelaps jettmari was Rats infected mites rate was 29.03%. Conclusion prevent the spread of disease caused by fleas, mites the dominant species and its composition ratio was 57. 1%. Efforts of vector control should be strengthened effectively to and other vectors at the port area.
