Objective To investigate the species, population density, habitat distribution, and seasonal trend of adult mosquitoes in Jiading district, Shanghai, China in recent years, and to provide a scientific basis for the control of mosquitoes and mosquito-borne diseases. Methods Adult mosquitoes were monitored by the CO2-baited baited light trap method in various habitats from 2018 to 2020, and analyzed mosquito species composition, seasonal fluctuation, and density differences between various habitats.Differences in mosquito species composition were examined using Chi-squared test, and ANOVA was used to analyze differences of density in different habitats. Results Culex pipiens pallens accounted for the highest proportion (82.70%) of the captured mosquitoes, followed by Cx. tritaeniorhynchus (10.32%) and Aedes albopictus (5.49%). The composition ratio of each mosquito species was significantly different in different years (P ≤ 0.001). The densities of Cx. pipiens pallens and Cx. tritaeniorhynchus peaked in June and July, respectively, being 2.28 and 0.39 mosquitoes/lamp·h, respectively. The peak periods of Ae. albopictus and Anopheles sinensis lasted for a longer time, appearing from June to September and from July to September, respectively. Among various types of habitats, the average mosquito density was highest in hospitals (1.41 mosquitoes/lamp·h) and lowest in parks (0.25 mosquitoes/lamp·h). Cx. pipiens pallens was the absolutely dominant species in all monitored habitats. The densities of Cx. tritaeniorhynchus (0.51 mosquitoes/lamp·h) and An. sinensis (0.07 mosquitoes/lamp·h) in livestock sheds were significantly much higher than their densities in other habitats (F=3.763, P=0.012; F=6.194, P<0.001). The peak time of Ae. albopictus varied greatly in different habitats. During the peak season of mosquito activity, Ae. albopictus densities in hospitals and parks showed a decrease followed by an increase, with the decline occurring in August and June, respectively. Conclusion The density of mosquitoes in Jiading district is generally at a relatively low level. However, mosquito control in hospitals, livestock sheds, and residential areas should be strengthened. Targeted, scientific, and effective control strategies should be taken according to the activity patterns of different mosquito species.
