目的分析云南省玉龙鼠疫疫源地宿主动物和媒介蚤类的组成、数量,探讨其疫源地性质,为鼠疫防治提供科学依据。方法2007年2-12月在疫源地及周边地区设9个监测点,室外采用鼠夹法,室内鼠笼法捕获小兽类,梳捡体蚤,鉴别种类。结果共捕获鼠型动物3目5科11属19中,共2390只,绒鼠(Eothenomys spp.)47.28%,齐氏姬鼠(Apodemus chevrieri)37.11%。其中的绒鼠经头骨鉴定大绒鼠(E.miletus)、玉龙绒鼠(E.proditor)和黑腹绒鼠(E.melanogaster)分别占19.09%,79.25%,1.66%,玉龙绒鼠在鹿子村、玉龙雪山是主要鼠种,其他监测点以大绒鼠为主。检获鼠体蚤2科6属6种共625只,方叶栉眼蚤(Ctenophthalmus quadratus)和特新蚤(Neopsylla specialis)数量最多,分别为62.08%和22.56%。棕形额蚤(Frontopsylla spadix)和缓慢细蚤(Leptopsylla segnis)占8.16%和5.28%,未发现印鼠客蚤(Xenopsylla cheopis)。结论该疫源地鼠型动物和鼠体蚤类构成与剑川疫源地类似,但也有其独特性。
Objective To analyze the composition and quantity of host animals and vector fleas in the Yulong plague foci of Yunnan Province and discuss the nature of their foci and provide a scientific basis for the prevention and control of plague. Methods From February to December 2007, 9 monitoring sites were set up in the foci and the surrounding areas, and the outside was captured by the mouse clamp method. The indoor squirrel cage was used to capture the small mammals and the combs were collected to identify the species. Results A total of 2390 mice belonging to 11 genera, 3 orders, 5 families and 5 families were captured. Eothenomys spp. 47.28% and Apodemus chevrieri 37.11%. Among them, E.miletus, E.proditor and E.melanogaster accounted for 19.09%, 79.25% and 1.66% of the total amount of the cashmere skulls, Village, Jade Dragon Snow Mountain is the main species of rats, other monitoring points to the main plush. There were 625 species of 6 genera in 2 families, 625 species were found in the flea genus. The majority of Ctenophthalmus quadratus and Neopsylla specialis were 62.08% and 22.56% respectively. Frontopsylla spadix and Leptopsylla segnis accounted for 8.16% and 5.28%, respectively. Xenopsylla cheopis was not found. Conclusion The fleas in the murine and mouse body of the foci are similar to those of the Jianchuan Foci, but they also have their unique features.
