Abstract: Objective To investigate species composition on gamasid mites,chigger mites and flea on the rodent in frontiers of Korea,Russia and Northeast China. Methods To catch rodents with cage,and collect the ectoparasites of the rodent. Results 15 891 ectoparasites of the rodents belonged to 9 family,27 gerea and 55 species,which were recorded from 6 cities and counties of frontiers Northeast China,of which gamasid mites belonged to 20 species,9 gerea and 4 family;chigger mites were 15 species ,6 gerea and a family;flea survey were 20 species,12 gerea and 4 family. The species composition of the rodent ectoparasites varies with different rodents species. Conclusion Base is given for further studies on faunal distribution and species composition on rodent ectoparasites in frontiers of Korea,Russia and Northeast China.
