东北边境地区鼠体外寄生蜱螨的种类组成研究

Study of Species Composition on the Ectoparasitical Acarinids of the Rodent in Frontiers of Northeast China

采用笼日法捕鼠,收集鼠体外寄生蜱螨,研究我国东北边境地区鼠体外寄生蜱、革螨和恙螨的种类组成。结果表明,在东北边境6市县9种鼠体采获寄生蜱螨16565只,计16属39种,其中蜱类3属4种,革螨8属20种,恙螨5属15种。优势种群:全沟硬蜱(75.6%);耶氏历螨(25.5%),厩真历螨(21.1%);波氏新恙螨(35.0%),高丽新恙螨(22.7%)。不同鼠体寄生蜱、革螨、恙螨的主要种类组成有所不同。

To catch rodents with cage and collect ectoparasitical acarinids of the rodent, study spocies composition of ectoparasitical ticks, gamasid mites and chigger mites on the rodent in frontiers of Northeast China. The results indicated that 16 565 acarinids belonged to 39 species and 16 genera on 9 species rodents from 6 couties in frontiers of Northeast China, of which ticks belonged to 4 species and 3 genera, gamasid mites were 20 species and 8 genera, chigger mites were 15 species and 5 genera. The predominant species of ticks were Ixodes persulcatus （75.6%）; gamasid mites were Laelaps jettmam （25.5%） and Eulaelaps stubularis （21.1%）; chigger mites were Netrombicula pomeranzevi （35.0%）andNetrombiculagardellai （22.7%）. The mostly species composition of ectoparasitical ticks, gamasid mites and chigger mites on rodents varies with different rodent species.
