Abstract: Objective To compare the surveillance results of Aedes albopictus between Guangzhou emergency mosquito vector control team (municipal emergency response teaml) and district Center for Disease Control and Prevention (CDC) of Guangzhou and to provide a scientific basis for the prevention and control of vector-borne diseases such as dengue fever. Methods The weekly data of the surveillance of dengue vector Ae. albopictus in Guangzhou from March to December in both 2016 and 2017 were collected. The data were summarized and statistically analyzed by WPS Excel and SPSS 17.0 softwares. The comparison of risk levels was performed by the paired Chi-square test. Results The mean standard space index (SSI), mosquito ovitrap index (MOI), and adult mosquito density index (ADI) monitored by the city emergency team were 1.46, 6.02, and 2.87, respectively. The average SSI, MOI, and ADI of each district level were 0.41, 7.29, and 1.83, respectively. The density dynamics of Ae. albopictus were almost the same in the streets, towns, and parks of the city emergency team and each city district level, which peaked from May to August, and then declined gradually from October. The proportion of Ae. albopictus surveillance sites at the city emergency team meeting the requirements of mosquito vector control was about 50.49% of those at the district level, and the proportions of low, medium, and high transmission risks were higher than those of each city district level. The number of parks, schools, hospitals and other places as surveillance sites at the city emergrncy team was relatively small, which only accounted for 12.86% of the total number of surveillance sites in the city emergency team. The surveillance at the city emergrncy team had higher risk level than that at each district level at the same time and at the same location. Conclusion The mutual complementation needs to be realized between the Guangzhou mosquito vector emergency team and district CDCs regarding surveillance of Ae. albopictus. They can jointly guide the prevention and control of mosquito-borne infectious diseases such as dengue fever through comprehensive evaluation of the control effect of Ae. albopictus.

摘要： 目的 比较广州市蚊媒应急队（市应急队）与广州市各区疾病预防控制中心（市各区级）白纹伊蚊监测结果，为登革热等媒介伊蚊传播疾病的预防控制提供科学依据。方法 收集2016－2017年3－12月的广州市登革热媒介白纹伊蚊监测周报数据，采用WPS Excel和SPSS 17.0软件对数据进行汇总和统计分析，风险等级比较采用配对χ²检验。结果 市应急队监测的平均标准间指数（SSI）、诱蚊诱卵器指数（MOI）和成蚊密度指数（ADI）分别为1.46、6.02和2.87，市各区级的平均SSI、MOI和ADI分别为0.41、7.29和1.83；市应急队与市各区级在街镇和公园监测的白纹伊蚊密度动态消长情况大致相同，均在5－8月达最高，从10月开始，蚊媒密度均逐渐下降；市应急队开展的白纹伊蚊监测点达到蚊媒防控要求的比例约为市各区级的50.49%，低、中、高度传播风险的比例均高于市各区级；市应急队监测点中公园及学校、医院等场所的数量较少，仅为市应急队监测点总数量的12.86%；同一时间、同一地点市应急队监测的风险等级比市各区级监测结果高。结论 广州市蚊媒应急队和各区CDC的白纹伊蚊监测工作应相互补充，综合评价白纹伊蚊控制效果，共同指导登革热等媒介伊蚊传播疾病的防控工作。
