为了进一步探索革螨在流行性出血热(以下简称出血热)流行病学的意义,我们于1976年3月至1977年2月、1977年6月至1978年2月在丹阳县先后选择出血热发病数相近、地形、土质、植被等自然条件基本相同的陵口、折柳、横塘公社,进行了黑线姬鼠鼠体和窝巢的革螨种群分布的季节消长的调查,现将结果报告如下。调查方法调查系用定点、定数、定人、定时的野外挖洞法,每半个月查二十个有鼠鼠窝。为了捕到鼠窝中的鼠,挖洞时间根据鼠类活动规律而定,春秋季节一般鼠类夜间活动,在白天挖洞。冬天气温低,鼠类一般白天觅食,故在早上和傍晚挖洞。挖鼠洞的同时测气温、
In order to further explore the leather mite epidemiological significance of epidemic hemorrhagic fever (hereinafter referred to as hemorrhagic fever), we in March 1976 to February 1977, from June 1977 to February 1978 in Danyang County have selected hemorrhagic fever The incidence of similar, topography, soil, vegetation and other natural conditions are basically the same Lingkou, Liu Liu, Wang Tong communes, black line Apodemus murine and nest nest leather mite population distribution of the seasonal decline survey results now The report is as follows. Investigation Method Survey Department of fixed-point, fixed number, set people, regular field digging method, every two weeks check twenty rat rat. In order to catch mice in the rat’s nest, the burrowing time is determined according to the rules of the mouse activity, and during the spring and autumn, the mouse activity at night usually burrows in the daytime. Winter temperatures are low, mice usually foraging during the day, so digging holes in the morning and evening. Excavating the hole at the same time measuring temperature,
