摘要:

目的 调查定边县鼠疫疫区革螨种群构成,为进一步研究革螨在传播和保存鼠疫菌中的作用提供基础资料。方法 鼠体螨采集法、窝巢螨采集法。采集的革螨用霍氏液封片,制成革螨玻片标本,光学显微镜下鉴定螨种。结果 共收集革螨3科5属6种463只,北野血革螨占检获总数的40.6%,格血厉螨占33.0%,仓鼠真厉螨占24.8%; 其它为少量宫卵巨螯螨、褪色巨螯螨和阿尔及利亚厉螨。捕鼠859只,挖巢135个。长爪沙鼠为主要宿主动物,占总捕鼠数的90.9%。长爪沙鼠鼠体带螨率7.3%,窝巢带螨率23.7%。收集的革螨绝大多数为雌性个体。结论 主要鼠种寄生革螨种类少,群落结构简单。北野血革螨、格血厉螨、仓鼠真厉螨为长爪沙鼠寄生的优势螨种。

Abstract:

Objective To investigate the community structure of gamasid mites in a plague area of Dingbian county for further revelation of the role of these species in transmitting and preserving the plague bacillus. Methods The mites were collected from rodent bodies and nests, fixed in Hoyer’s medium and identified under the microscope. Results A total of 463 gamasid mites under 6 species, 5 genera and 3 families were collected. The dominant species included Haemogamasus kitanoi, Haemolaelaps glasgowi and Eulaelaps cricetuli, accounting for 40.6%, 33.0% and 24.8%, respectively, followed by a small amount of Macrocheles matrius, Macrocheles decoloratus and Laelaps algericus. Eight hundred fifty-nine rodents were captured and 135 nests were investigated. The dominant host mammal was Meriones unguiculatus, accounting for 90.9% of the total captives. The mite-carrying rate was 7.3% in M. unguiculatus and 23.7% of all nests. Most of the collected mites were female. Conclusion The community structure of gamasid mites is simple in this area with only a few species parasitic on the dominant host rodents. The dominant gamasid mites found on M. unguiculatus included H. kitanoi, H. glasgowi and E. cricetuli.
