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.
