摘 要:黑线姬鼠是吉林省多种生境中的优势鼠种。本研究表明,黑线姬鼠在四种生境中的构成比超过30%,年度间构成比有差异。各生境中幼、成比不同,年度间幼、成比有所差别。各生境性比(♂∶♀)基本一致,且多种生境中大于1;年度间性比有所差别。黑线姬鼠密度逐年下降,但降低幅度逐年减小。每年呈双峰型规律消长,高峰出现时间较稳定,即每年6~7月和9~10月。上述规律同吉林省流行性出血热(EHF)发病率变化规律基本一致。Studies on dynamic state of A. agrarius infestation in eight habitats have been done in Jilin Province. A.agrarius was the dominant species in most of habitat, constitution ratio of A. agrarius in four habitats surpasses 30%. Constitution ratio of A.agrarius in every year were different. Age ratio (young/adult) inevery habitat and year were different . Sex ratio ( male/female) in every habitat were identifiable, but in every year were different. The curve of A. agrarius population density of each month during eight years shows that the population density come down every year and the range of fall reduces year by year. There were two speaks of population density every year (on June to July and September to October) .These laws were approximately the same to that the EHF morbidity changes.
