摘要: 本文对福建家鼠寄生蚤的数量及组成比进行了统计、分析、比较,1981~1990年总蚤指数比1952~1066年低一倍:在北部,缓慢细蚤比1952~1966年明显减少。1981~1990年蚤类组成比以印鼠客蚤(Xenopsylla cheopis)占优势(65.90%),但南部和北部组成比有所不同,印鼠客蚤和缓慢细蚤(Leptopsylla segnis)南部多于北部,不等单蚤(Monopsyllus anisus)的数量在我省北纬24°~28°不同纬度间依次递增,说明该蚤的分布有明显的区域性。

Abstract: In this paper,the author has made a statistics on the population densities & species composition proportions of three species of fleas parasited on domestic rodents in Fujian during 1981-1990,which is compared with the data obtained during 1952-1966.The results show that the population index of all fleas in 1981-1990 was only half time thanlower hat in 1952-1966,and the population density of Leptopsylla segnis was distinctly lower in 1981-1990 than in 1952-1966.During 1981-1990,the different species composition proportions were 65.90%of Xenopsylla cheopis.17.55% of L. segnis and 16.35% of Monopsyllus anisus. Furthermore,the population densities of X. cheopis & L. segnis were higher in south than in north of Fujian。The population density of M.anisus increased gradually from 24°to 28° of north latitude. Which shows the regular ar ea distribution of this species of flea.
