东北中朝俄边境地区鼠染体外寄生虫的率及指数调查

目的 调查我国东北中朝俄边境地区鼠染体外寄生蚤、革螨、恙螨的率及指数。方法笼日法捕鼠，采集其体外蚤、革螨和恙螨。结果在6县(市)捕获鼠类10种，捡蚤2433只，鼠总染蚤率为52．2％，指数为1．7，其中大仓鼠染蚤率(73．8％)及指数(5．4)最高。采获革螨7497只，鼠总染革螨率为58．3％，指数为3．8，其中大林姬鼠的染革螨率最高(68．0％)，大仓鼠染革螨指数最高(12．8)。采获恙螨9295只，鼠总染恙螨率为31．0％，指数为6．8，其中红背Ping染恙螨率最高(92．0％)，东方田鼠染恙螨指数最高(51．3)。结论对东北中朝俄边境地区鼠染体外寄生蚤、革螨和恙螨的率和指数进行研究，为开展鼠及体外寄生虫的防制提供了参考。

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.
