吉林省七年鼠情监测结果分析

吉林省经七年来的鼠情监测,基本查清与人们接触密切的鼠类,特别是传播疾病的主要鼠类的分布规律,分析出我省家鼠有两个高峰(6月和10～11月),野鼠也有两个高峰(6月和10月),这与我省流行性出血热两个高峰相吻合,鼠峰在病峰之前。1986年以后,由于我省开展大规模灭家鼠活动,家鼠高峰已不存在规律性。通过几年来的灭鼠活动,使家鼠密度呈下降趋势,城镇褐家鼠和小家鼠构成比发生变化。城镇未爆发家鼠型流行性出血热。鼠情监测为灭鼠防病工作提供了科学依据。

An Analysis on The Monitoring Result of Rodent infestation for seven years in Jilin Province.

A monitoring result of rodent infestation for seven years in Jilin province has by and large'found out the distribution of human beings the rodents contacting closely to especially the species that spread diseasses to man. It has been shown that there are two density peaks for both commensal rodents ty (in June and between October and November) and field the species( in June and in October), which coincide with the two peaks of EHF incidence in Jilin province, and the peaks for rodent are anterior to those for the disease. Since 1986, the peaks of commensal rodent density have become irregular because of the extensive commensal rodent control campaign which has made the density tend to decline. The constitution ratio of Rattus norvegicus to Mus musculus has changed in cities and towns and no break-out of Rattus EHF appeared recent years. The monitoring result provides the scientific basis for rodent control and disease prevention.
