摘要
笔者于1992年2月至1993年1月,在玉溪市两个自然村室内进行了鼠类及体外寄生蚤类调查研究.鼠类年均捕获率7.25%;褐家鼠为优势种,占73.49%,捕获率高峰期在9月;黄胸鼠和小家鼠为常见种,捕获率高峰期分别在3和4月。3种家鼠年均孕鼠率为14.57%,平均胎仔数为7.3只,10月为全年生殖高峰。鼠体染蚤率54.3%,总蚤指数3.15匹/鼠;印鼠客蚤和缓慢细蚤为优势种,前者数量高峰期在9~10月,后者出现3个高峰曲线,高峰期指数较稳定,不等单蚤为常见种,高峰期在12月。鼠体染蚤率与总蚤指教基本一致。
During the February 92 and January 93,we investigated the home rats and their ectoparasitic fleas in two natural villeges of Yuxi City, The mean rat-captured rate in one year was 7.25%, the Rattus norvegicus was the most common(73.49%),and the peak of capturing was in the September, Rattus flavipectus and Mus musculus were the common species, the peak of capturing rate was in the March and the April, respectively,The mean rat pregnant rate was 14.57%,the average number of the cffapring in a rat is 7.3,in which the peak time of the teproducti on tate was in the October during a year.The rate of rats infected with fleas was 54.3% the total flea indez was 3.15 Xenopsylla cheopis and Leptopsylla segnis were is the dominating species The former peak phase during the August to the ctober, the latter presented three peak curves;the index of the peak was stable,and the Monopsyllus anisus was the common species which the peak was in the December,and the rate of rats infected with fleas was compatible with the total flea index.
