Abstract: Objective To analyze the role of National Sanitary City construction on vector control in Baiyin,Gansu province,China,and to provide reference and guidance for sustainable vector control in the future.Methods We collected data on vector density monitoring,on-site vector assessment,and insecticide resistance monitoring for National Sanitary City construction in Baiyin from 2017 to 2021,and analyzed the changes in various vector indicators since National Sanitary City construction using the chi-square test,analysis of variance,and t test.Results Since National Sanitary City construction in 2017,the densities of mosquitoes,flies,rodents,and cockroaches showed a decreasing trend in Baiyin district and Pingchuan district,with significant changes from 2017 to 2021(mosquitoes:F=180.443,P<0.001;flies:F=67.948,P=0.001;rodents:F=59.644,P<0.001;cockroaches:F=27.688,P=0.013).According to on-site vector assessments for National Sanitary City,the infestation rates of flies,rodents,and cockroaches significantly decreased from 2019 to 2021(flies:χ2=245.253,P<0.001;rodents:χ2=26.845,P=0.001;cockroaches:χ2=72.647,P<0.001).The pass rates of fly-and rodent-proof facilities increased year by year,achieving the national standard C level of vector density control or higher.Local flies showed varying degrees of resistance to five commonly used insecticides.The resistance level of domestic flies was higher in the counties or districts constructing National Sanitary City than in those not constructing.Conclusion National Sanitary City construction has promoted vector control in Baiyin,and decreased vector densities through comprehensive measures including environmental reform,breeding habitat treatment,and chemical control.However,the insecticide resistance of vectors has increased in Baiyin.Based on ecology,insecticide resistance,and pathogenic monitoring,future vector control should continue to strive for government support,combine the pest control operation and the general public,and take multiple measures to consolidate the achievements of the National Sanitary City and create a beautiful,civilized,and livable environment.

摘要: 目的 分析国家卫生城市创建对甘肃省白银市病媒生物防制的促进作用和效果影响,为今后病媒生物可持续防制提供借鉴和指导。方法 收集2017-2021年白银市国家卫生城市创建(创卫)病媒生物密度监测、现场评估和抗药性监测数据,采用χ2检验、方差分析、t检验等方法分析国家卫生城市创建后上述各指标的变化。结果 2017年开始创卫以来,白银市创卫县(白银区和平川区)蚊、蝇、鼠和蜚蠊密度呈逐年下降趋势,2017-2021年间密度差异均有统计学意义(蚊:F=180.443,P<0.001;蝇:F=67.948,P=0.001;鼠:F=59.644,P<0.001;蜚蠊:F=27.688,P=0.013);创卫后的2019-2021年病媒生物现场评估蝇、鼠、蜚蠊的侵害率逐渐下降,各年间差异均有统计学意义(蝇:χ2=245.253,P<0.001;鼠:χ2=26.845,P=0.001;蜚蠊:χ2=72.647,P<0.001),防蝇、防鼠设施合格率逐年提高,均达到国家病媒生物密度控制水平C级以上标准;当地家蝇对5种常用杀虫剂的抗药性水平不同,创卫成功的县(区)家蝇抗药性水平均高于未创卫的县(区)。结论 创卫促进了辖区病媒生物防制工作,通过环境改造、孳生地处理、化学防治等综合措施使病媒生物密度显著下降,但也可能导致辖区病媒生物产生抗药性,今后应以生态学、抗药性、病原学监测为基础,继续争取政府支持,发挥有害生物防制业和群众相结合模式,多项措施并举,巩固国家卫生城市成果,为群众创造美好、文明的宜居环境。
