目的摸清部队营区蚤类及其宿主的种群和地理分布,评价蚤防治效果。方法选择18个营区及其周围作为调查点,收集啮齿动物及体表蚤,并对蚤和宿主进行分类鉴定;使用20%高效氯氰菊酯+残杀威乳油连续2次施药。结果 18个营区共捕获啮齿动物675只,分为2目5科11种,其中啮齿目分为3科5属9种;自兽体表获蚤882只,染蚤率为45.63%,蚤指数为1.31。以背纹仓鼠的染蚤率(59.65%)最高,蚤指数以大仓鼠(2.44)最高,带蚤种类以褐家鼠(7种)最多;共获蚤932只,经鉴定分为11属13种,人蚤、印鼠客蚤、不等单蚤和二齿新蚤各调查点均有分布,二齿新蚤(36.37%)为营区优势蚤种;3个营区观察点灭蚤前阳性指数为0.21,灭后降至0.004,平均灭蚤率为97.96%。结论部队营区及其周围蚤类宿主呈多样性分布,蚤种群较单一,结合营区综合治理和鼠类防治开展药物灭蚤效果显著,可在蚤危害的营区推广应用。
Objective To find out the population and geographical distribution of fleas and their hosts in battalion barracks and to evaluate the control effect of fleas. Methods 18 battalions and their surroundings were selected as investigation sites to collect rodents and body fleas, and the fleas and hosts were classified and identified. Two successive doses of 20% beta-cypermethrin and carbamazepine were used. Results A total of 675 rodents were captured in 18 battalions and divided into 2 orders, 5 families and 11 species. Among them, rodents were divided into 9 families of 3 families, 5 genera and 9 species. 882 fleas were collected from the beast body, the flea flea rate was 45.63% Is 1.31. The rate of flea infection (59.65%) was the highest in desiccated hamsters, the highest in flea index was in hamster (2.44), and the number of fleas in flea was the largest in Rattus norvegicus (9 species). A total of 932 fleas were identified and divided into 11 genera 13 Species, flea, Indian rat fleas, not equal to the single flea and bifidal flea survey points are distributed in the survey, New Daphnia magna (36.37%) for the dominant camp flea species; campsite observation point positive flea flea before 0.21, down to 0.004 after extinction, the average flea-killing rate was 97.96%. Conclusion The flea hosts in the battalion and its surrounding areas are distributed in a variety of ways. The population of fleas is relatively monotonous. Combining with the comprehensive management of the camp area and the prevention and control of rodents, the drug flea flea has a remarkable effect and can be popularized and applied in the camps affected by fleas.
