【摘要】 目的掌握"四害"密度及变化,为除四害提供科学依据。方法按卫生部《全国病媒生物监测方案》制定十堰市城区四害密度监测方案。结果老鼠阳性率为0.28%,苍蝇平均密度0.14只/笼(带),蚊虫密度0.97只/人工小时,蟑螂密度指数0.08只/(盒.夜)。结论四害密度处于较低水平,种类变化不大,除四害以环境防制为主,辅以化学药物,把四害密度控制在较低水平。更多还原

【Abstract】 [Objective]To master the density and changes of the Four Pests,provide the scientific basis for eliminating the Four Pests.[Methods]According to the National surveillance plan for vector density(Ministry of Health),the surveillance plan for the Four Pests density in Shiyan urban area was developed.[Results]The positive rate of the rats was 0.28%,the average density of the fly was 0.14 per cage,the density of the mosquito was 0.97 per labor hour,and the density of the cockroach was 0.08 per box night.[Conclusion]The density of the Four Pests is at a low level,and the species changes are not obvious.The Four Pests elimination should be dominated by environment control,assisted by chemical drugs,so as to keep the density of the Four Pests at a low level.更多还原
