【摘要】：目的对滇西地区室内地面游离蚤进行调查和分析,了解蚤类分布和构成情况,评估蚤媒疾病传播的风险。方法选择滇西地区10个县(市、区),每县选择4个自然村,每村随机抽取20个家庭,共800个家庭。每户室内放置10个水盘,连续3晚,每日晨捡蚤,显微镜下进行蚤种鉴定,计算捕获率、蚤指数、构成比及雌雄比。结果 800个家庭中,346个家庭(43.25%)捕到地面游离蚤。放置24 000水盘/夜,捕获地面游离蚤2406匹,捕获率为10.03%,蚤指数为0.100;分属3科5属5种,其中人蚤占72.73%。雌雄比为1∶0.65。结论滇西地区室内地面游离蚤中,人蚤为优势蚤种。蚤媒疾病发生的条件与风险仍然存在,应加强蚤情监测,及时采取灭蚤措施,防止蚤媒疾病的发生与流行。
[Abstract]:Objective to investigate and analyze the indoor free fleas in western Yunnan, to understand the distribution and composition of fleas, and to assess the risk of flea-borne disease transmission. Methods 10 counties (cities, districts, 4 natural villages) were selected. A total of 800 families were randomly selected from 20 families in each village. 10 water pans were placed in each household for 3 consecutive nights. The fleas were picked up daily in the morning. The flea species were identified under the microscope, and the catch rate and flea index were calculated. Results out of 800 families, 346 families (43.25) caught free fleas on the ground. By placing 24000 water plates per night, 2406 free fleas were captured, with a catch rate of 10.03 and a flea index of 0.100; 5 species belonging to 3 families, 5 genera and 5 species, respectively. The ratio of male to female is 1: 0.65. Conclusion in the indoor free fleas in western Yunnan, human fleas are the dominant species. The conditions and risks of flea-borne diseases still exist. It is necessary to strengthen the monitoring of flea situation and take flea killing measures in time. To prevent the occurrence and prevalence of flea-borne diseases.
