Study of infection rates and indices of the ectoparasites on the rodent in frontiers Korea, Russia and northeast China

Objective To investigate infested rates and indices of fleas, gamsid mites and chigger mites on the rodents in frontiers of Korea, Russia and Northeast China. Methods To catch rodents by the cage,collection fleas, gamasid mites and chigger mites. Results 10 species rodents were catched in 6 cities and countries. ~2 433 fleas were collected, the rodents with total infested rated and infested indices by fleas are ~52.2% and ~1.7 respectively. Cricetulus triton with higher infested rates and infested indices by fleas are ~73.8% and ~5.4 respectively. ~7 497 gamasid mites were collected, the rodent with total infested rates and infested indices by gamasid mites are ~58.3% and ~3.8 respectively. The rodent with higher infested rates of gmasid mites is Apodemus speciosus ~(68.0%) ,and higher infested indices by gmasid mites is Cricetulus triton ~12.8 . It was collected for ~9 295 chigger mites,the rodent with total infested rates and infested indices by chigger mites are ~31.0% and ~6.8 respectively. The rodent with higher infested rates by chigger mites is Clethrionomys rufocanus ~(92.0%) , and higher infested indices by chigger mites is Microtus fortis ~(51.3) . Conclusion The infested rates and indices of fleas, gamasid mites, chigger mites on rodeuts in frontiers of Korea, Russia and Northeast China were givea which is favorable for rodents and their ectoparasites control.
