南京市城区蚊虫综合治理效果的研究

目的研究在城市生态环境中采取针对蚊幼防治的蚊虫综合治理效果。方法在南京市的试验区，开展健康教育和蚊虫孳生地处理，采用诱蚊灯法和诱蚊诱卵器法分别监测库蚊和伊蚊密度。结果采取综合治理措施后，试验区库蚊和伊蚊的相关密度指数分别为0．123和0．132，与对照区相比，密度下降率分别为87．7％和86．8％，蚊虫密度平均为1．2只／灯，阳性孳生地下降率为95．5％。结论针对蚊幼的综合治理有较好的防治效果。采取政府机构开展人群的健康教育、居民清除自家的各种蚊幼孳生地、专业除害队伍清除公共地段的蚊幼孳生地，并对无法清除积水的区域投加灭蚊幼缓释剂的蚊虫综合治理策略，可在城市灭蚊工作中推广应用。

Study on the effect of integrated mosquito control in Nanjing, China

Objective To study the effect of integrated control aimed at mosquito larvae in the urban environment. Methods The health education to the urban residents and treatment of mosquito breeding sites were conducted in the test zone of Nanjing city. The densities of Culex and Aedes mosquitoes were monitored by light traps and ovitraps. Results The population related index（PRI） of Culex and Aedes mosquitoes were 0. 123 and 0. 132 respectively, and decreased by 87.7 % and 86.8% respectively. The mean of mosquito population was 1.2 for one lamp and the decreased rate of positive breeding sites was 95.5 %. Conclusion There is good effect in the urban integrated control aimed at mosquito larvae. It is valuable and practicable to adopt the strategy of the integrated mosquito control in the city. For example, health education is conducted to all people by government, their own mosquito breeding sites are cleared away by the urban residents themselves, the mosquito breeding sites in the public places are cleaned up and the larvicide is used in permanent breeding sites by pest control operators （PCO）.
