目的及时掌握洪涝灾区病媒生物密度变化情况,为虫媒传染病的防治提供依据。方法采用目测法、笼诱法、粘捕法和笼日法分别测定灾后蚊、蝇、蟑和鼠密度。结果灾后蚊幼滋生地多为小型积水,农村阳性率高于城区;蝇密度城区灾民安置点明显高于乡镇、村;蟑、鼠密度未见明显性变化。结论灾后不宜进行大范围化学杀虫、应根据监测数据对虫媒密度高、重点部位进行化学防治处理,一般地区以环境治理为主。
Objective To grasp the change of vector density in flooded areas in time and provide the basis for the prevention and control of vector-borne diseases. Methods The density of mosquitoes, flies, cockroaches and mice were determined by visual inspection, cage induction, stick-catching method and cage-cage method respectively. Results Most mosquito and juvenile breeding areas were small waterlogging, and the positive rate in rural areas was higher than that in urban areas. The resettlement points of the victims in urban areas were significantly higher than those in towns and villages. The density of cockroaches and mice did not change significantly. Conclusion It is not advisable to carry out a wide range of chemical insecticides after a disaster. Based on the monitoring data, chemical insecticides should be treated at high density and key sites. In general, the area is dominated by environmental management.
