Abstract: Objective To study the composition of mosquitoes in underground spaces (including parking garages and air-raid shelters) of Jing'an district, Shanghai, China in winter, and to explore effective methods for mosquito control. Methods In January 2019, 15 underground spaces, which had mosquito infestation in winter before, were selected from Jing'an district, Shanghai, and 1% temephos granules were used to control the mosquito-positive standing water habitats. An investigation was performed using the labor hour method and ladle method. The Wilcoxon rank-sum test was used to compare the mosquito density changes to evaluate the control effect. Results Before control, the mean temperature and humidity of the selected sites in the experimental group were 10.76℃ and 56.96%, respectively. The positive rate of mosquitoes in standing water habitats was 25.93%, and the ladle index was 3.17 mosquito larvae/scoop. The mean adult mosquito density was 5.39 mosquitoes/room·h. A total of 92 female mosquitoes (91.09%) were captured, all of which were Culex pipiens complex, with an ovarian development ratio of 5.43%. The proportions of blood sucking and fat body accumulation were 1.09% and 15.22%, respectively. After control, the positive rate of mosquitoes in standing water habitats was 0, and the mean adult mosquito density was 0.21 mosquitoes/room·h, which was significantly lower than that before control (F=3.186, P=0.001). During the same period, the adult mosquito density in the uncontrolled underground space was 6.49 mosquitoes/room·h, which was significantly higher than that in the controlled sites (F=2.823, P=0.005). Conclusion In winter, there are still mosquito breeding in the underground areas of Jing'an district, Shanghai. Using 1% temephos granules to control the breeding sites such as rainwater wells and water-collecting wells can effectively reduce the mosquito density.
