摘要
自1985年4—11月作者对山东省鼠类及体外寄生革螨进行了调查。捕获鼠类7种,隶属于2个科。检获革螨21种,隶属于6科,12属。其中山区血革螨,橄形血革螨,拟达呼尔血革螨,巴钝绥螨,混毛绥螨和里新约螨为山东首次报道。其中社鼠为矮肛厉螨,鼩鼱赫剌螨,厩真厉螨和三角血厉螨的新宿主报道。大林姬鼠为三角血厉螨的新宿主报道。聚类分析表明,大仓鼠和黑线姬鼠;社鼠和大林姬鼠;褐家鼠和小家鼠;黑线仓鼠可划分为四个不同的生态组。山区、丘陵和平原农耕区在鼠体寄生螨的群落的种类组成上有一定差异。调查说明社鼠喜欢栖居于山区。黑线姬鼠为山东省野生鼠类的优势种。
From April to Novermber, 1985, 2597 Gamasides (belonging to 6 families,12 genera and 21 species) were collected from 7 rodent species(Apodemus agrarius, A. speciosus, cricetulustriton, C. barabensis, Niviventerconfucianus, R. norvegicus and Mus muscuius)trapped from 13 districts in Shandong province. of 376 rodents, 293 or 77.9% were infested with mites. Six Species of these gamasides (haemogamasus moncicola, H. oliviformis, H. paradouricus, Amblyseius barkeri, Lasioseius confucus and Neojordensia levis)are the first time reported from Shandong. Niviventer confucianus is a newly reported host of Proctolaelaps pvgmaeus, Haemolaclaps triangularis, Hirstionyssus sunci and Eulaclaps stabularis. H. triangularis is found for the first time on the body of A. speciosus in this province. Cluster analysis demonstrated that species composition of gamasides are different from Mountain ranges, Hilly lands and Plain districts. These differences are closelv related to their characteristic habitats. C. triton and A. agrarius, N. confucionus and A.speciosus, R.norvegicus and M.musculus, C.barabensis are clustered into four ecological groups, which are grouped according to their ectoparasite similarity. A.agrarius is the predominant rodent species in Shandong. The distribution of N. confucianus is restricted to the Mountain Tai district.
