摘要
目的描述光滑拟颚虱和古北拟颚虱的形态并讨论其医学意义。方法在新疆长尾黄鼠、灰旱獭和喜马拉雅旱獭体采集这两种吸虱标本,制片鉴定后描述两性形态并绘图。结果光滑拟颚虱和古北拟颚虱的形态与金大雄(1999)的描述基本一致。本文增添了光滑拟颚虱雌性外生殖器、古北拟颚虱两性全图和雄性外生殖器伸出体外时的形态图。结论首次用中国的标本记述以上两种吸虱形态。二者均能自然感染鼠疫菌,且感染率较高,因此它们在鼠疫疫源地的保存方面可能具一定的意义。
Objective To describe the morphology of Linognathoides laeviusculus （ Grube, 1851 ） and L. palaearctus Olsoufiev, 1938 and discuss their medical significance. Methods The specimens of the two sucking lice species were collected from Citellus undulatus, Marmota baibacina and M. himalayana. The sheet glass specimens were made for classification and distinction. According to the specimens, male and female morphology of the two species was described and figured. Results The morphology of L. laeviusculus and L. palaearctus is the same basically to that described by JIN Da - xiong （ 1999 ） , and the figures of female out - reproductive organs of L. laeviusculus, two sex full body of L. palaearctus and male out - reproductive organs stretched out of the body were added in this paper. Conclusious The sucking lice from Citellus undulatus and Marmota （ M. baibacina and M. himalayana ） are L. laeviusculus and L. palaearctus respectively. The morphology of aforesaid two species is first described with Chinese specimens. Both of them can be infected with Yersinia pestis wtih a high infective rate. Therefore they might possess significance in conservation of plague foci to some extent.
