目的 研究影响社区外环境有害生物防制服务工作质量的关键因素，为提高城市有害生物控制质量提供依据。方法 项目督导组通过投标形式，受武汉市爱国卫生运动委员会办公室委托，以第三方专业机构的身份，按自定的《督导方案》，于2010－2014年对武汉市有害生物防制（PCO）公司承包的712~1 006个社区外环境有害生物防制工作质量进行督导考核。结果 2010－2014年2 000延长米的鼠迹数≤2.30，蚊幼阳性路径指数≤0.73，蜚蠊成若虫阳性房间率≤1.63％，蝇幼虫及蛹的检出率≤8.91%。民意调查知晓率为72.60%。结论 该督导项目促进了社区外环境有害生物防制工作质量，有效地控制了武汉市社区外环境有害生物密度，改善了居民生活环境；针对督导项目中发现的共性问题，提出了改进建议。

Objective To investigate the influencing factors of quality control on pest management services for the external environment, provide evidence to improve the service quality of pest control. Methods The performance of pest control in the external environment of community throughout the city that pest control operation(PCO)companies contracted with was evaluated by a project supervision panel through public bidding, as the third party specialist agency, and on a commission basis by Office of Patriotic Health Movement of Wuhan according to its internal supervision scheme. Results The results of evaluation on the performance of pest control in 712 to 1 006 community units in external environment that PCO companies contracted with from 2010 to 2014 were obtained. The five years'rodent density of extending 2 000 m was ≤2.30, Path index of mosquito larvae and pupae ≤0.73, and the positive rate of cockroach adults and nymphs indoor ≤1.63％, the positive rate of fly larvae and pupae ≤8.91%. The results met the required standards set forth by the National Patriotic Health Campaign Committee. Conclusion Through the supervising evaluation campaign, the quality of pest control in PCO companies was improved, the density of the four pests in the external environment of community of Wuhan city declined, the wellbeing of the residents was enhanced.
