Abstract:

Objective To grasp the Rhombomys opimus distribution characteristics and activity patterns, and to provide basic information to improve epidemic monitoring. Methods Circadian clamps of catching mice, single bagging seized ectoparasites identified routes caverns law sent to the laboratory survey observed activity patterns and comprehensive analysis of the R. opimus population distribution. Results In 11 ports in northern Xinjiang border five R. opimus population distribution, accounting for 66.7% of the entire ports in northern Xinjiang, the westernmost Xinjiang, longitude 80°37', latitude 43°40'are Lata port to longitude 82°48'north latitude and 46°41'Timbuktu port, especially in the highest density of Alashankou and two wings district, Xinjiang eastern longitude 93°20'31"north latitude and 44°14'32" port of Laoyemiao recent new found R. opimus distribution area. Found that the great gerbil not only mixed with wild rodents in vector exchange transfer. In the R. opimus distribution crossings average capture rate of 3.2%, 89.6% of the dye flea rate, the flea index 14.0, the major media in the border areas of the western region of Xinjiang and Kazakhstan R. opimus Xenopsylla minax in eastern Mongolia ports X. skrjabini. And describes the R. opimus annual seasonal, day activity patterns, caverns, nesting habitat, foraging characteristics. Conclusion The R. opimus in Kazakhstan, and Mongolia, the dominant species in the port vicinity, according to the distribution of the characteristics and activities of the law, to provide basic information to guide and improve epidemic monitoring.
