【摘要】 目的初步调查5.12地震灾后四川省汶川映秀镇小型兽类体表寄生虫.方法 2011年1月采用夹夜法和笼捕法捕获样区小型兽类,通过毛刷反复疏检,并用镊子逆毛检取捕获鼠体表寄生虫,然后按形态学分类方法进行鉴定.结果共捕获8只小型兽类,隶属2目2科、3属、4种.体表寄生虫隶属2纲5目,其中昆虫纲中有蚤目1属、1种,虱目2科3种,鞘翅目,虱啮目,蛛形纲中有蜱螨目1目、2股.褐家鼠体表寄生虫种类繁多,包括螨、蚤、虱、鞘翅目和虱啮目5种类型,其中褐家鼠革螨指数与蚤指数分别为12.5和0.75.结论所有小型兽类都发现体表寄生虫,其中褐家鼠在捕获小型兽类中是优势种,体表寄生虫丰富度和指数都较高,应引起密切关注.更多还原

【Abstract】 Objective: To investigate the community of parasites on small mammals in Wenchuan,Sichuan Province.Method: Small mammals are captured with mouse traps,and all the parasites on the body surface of the hosts are completely collected by using a double-edged fine-toothed comb and forceps.Results: A total of 8 small mammals are captured,which belong to 2 order,2 families,3 genera and 4 species.The parasites belong to 2 class,5 orders.The main kinds of external parasite are: gamasides,Siphonaptera,AnopiUra and Psocoptera.The Rattus norvegicus is infected with gamasides,flea,sucking lices,psocoptera,coleoptera.The indexes of flea and gamasid mite on Rattus norvegicus are 0.75 and 12.5,respectively.Conclusion: Rattus norvegicus is the dominant species of small mammals.Both the richness and diversity index of parasite commuity of Rattus norvegicus are high.So,close attention should be paid to this situation.更多还原
