大麝鼩是上海地区流行性出血热(EHF)主要传染源之一。近年来,作者对上海郊区农田生态系统中的大麝鼩生态学进行了初步调查和研究,观察到秋冬季大麝鼩种群的相对密度较高,10～12月份的夹夜捕获率分别为4.48、4.50、4.31,2月份以后的捕获率显著下降。大麝鼩一年有两个繁殖峰(3～5月及8～9月),冬季则有3～4个月的繁殖休止期。据136只大麝鼩胃的解剖分析,观察到其主要食昆虫、环节动物,不少胃内有鼠毛,也食少量植物和种子等。冬季大麝鼩和黑线姬鼠有集群及混居特性。冬季(12月)两兽的混居率高于秋季(10月),差异非常显著(t=3.62,P<0.01)。
Large musk deer is one of the main sources of epidemic hemorrhagic fever (EHF) in Shanghai. In recent years, the author conducted a preliminary investigation and research on the ecology of the Greater Musk deer in the farmland ecosystem in Shanghai suburbs. The relative density of the population of the large musk deer in autumn and winter was observed to be high, and the catching-night capture rates in October and December were respectively 4.48 , 4.50, 4.31, the capture rate after February decreased significantly. There are two breeding peaks in the big musk (3-5 months and 8-9 months), while the winter is 3-4 months breeding period. According to anatomical analysis of 136 large musk deer stomach, it was observed that its main food insects, annelids, many stomach rat hair, but also eat a small amount of plants and seeds. Winter Muskrat and Apodemus have cluster and mixed characteristics. In winter (December), the rate of the two beasts was higher than that in autumn (October), with a significant difference (t = 3.62, P <0.01).
