目的开展某部营区的蚤侵害调查,分析蚤害原因,评价蚤防治效果。方法蚤种类调查采用鼠体蚤指数法,粘蚤纸法用于营区不同场所蚤密度调查并评价灭蚤效果,蚤防治采用环境治理、大面积灭鼠和药物灭蚤相结合。结果捕获鼠25只,分类鉴定为3种,褐家鼠(84.0%)为营区优势鼠种;鼠体染蚤率为40.0%,鼠体蚤指数为2.12,蚤经分类鉴定为二齿新蚤、特新蚤指名亚种和缓慢细蚤3种,其中二齿新蚤(83.02%)为营区优势蚤种;不同场所蚤分布呈明显不均衡态势,以家属区贮藏室蚤密度最高,而人员活动密度最高的宿舍区则未捕获;通过2次药物处理后,所有场所灭蚤率均达100%。结论本次营区蚤害主要是由野猫和鼠类宿主活动带入,分布范围较广,危害较重,通过综合灭蚤措施,蚤害在短时间内得到了有效控制。
Objective To investigate the flea infestation in a certain barracks area, analyze the causes of flea infestation, and evaluate the control effect of fleas. Methods Fleas species fleas index method was used to investigate fleas flea density in different areas of the camp and to evaluate fleas flea control fleas prevention and control by environmental governance, a large area of rodent control and drug flea flea combination. Results Totally 25 mice were captured and classified into 3 species. Rattus norvegicus (84.0%) was the dominant species in the camp. The rate of flea infection was 40.0% in mice and 2.12 in flea index. The fleas were identified as Daphnia magna (Subspecies flea), New Zealand flea (subspecies) and slow flea flea (83.02%) were predominant flea species. The distribution of fleas in different habitats was obviously unbalanced, with the highest flea density The highest density of dormitory area was not captured; after two drug treatment, all places flea flea rate reached 100%. Conclusion The flea in this camp was mainly brought by the activities of host cats and rats and distributed in a wide range with heavy damage. The flea infestation was effectively controlled within a short period of time by comprehensive flea measures.
