Abstract:

Objective To explore the status of mosquito infestation in different types of residential areas in downtown Shanghai, and to analyze the causes and countermeasures. Methods Selecting 3 mosquito monitoring sites from 3 different types of downtown neighborhoods in the same area, conduct 224 days’ continuous mosquito monitoring in CO₂-light trapping method. Results Aedes albopictus is the predominant mosquito population in residential areas of downtown Shanghai (account for 72.35%), significantly higher than the density of sub-dominant Culex pipien pallens population (11.91 vs. 4.21/day·machine, P<0.05); Compared with the type of high-rise residential and old-fashioned villas environments, the old neighborhood environment faced more serious mosquito-infestation conditions, which has significantly higher mosquito density (total mosquito density, 28.91/day·machine, P<0.05), and much higher Ae. albopictus proportion (76.60%, P<0.05). Conclusion The situation of Ae. albopictus infestation in residential areas of downtown Shanghai is quite concerned, especially in old neighborhoods, whose living conditions and sanitary facilities are relatively poor. It is recommended that countermeasures should be taken to cope with the threat of Ae. albopictus-borne infectious disease in residential areas.
