Objective To study the correlations between population density indices of Aedes albopictus monitored in different types of residential areas, and to provide a basis for the rational use of Aedes mosquito monitoring indices. Methods The density monitoring indices of Ae. albopictus were investigated in 28 residential areas of four types in Pudong New Area, Shanghai, China, and their correlations were analyzed by Pearson correlation analysis. Results From May to October, the highest container index (CI) of 28 residential areas was found in enterprise dormitories (35.78%), the highest housing index (HI) was in rural cooperatives (6.74%), the highest mosquito ovitrap index (MOI) was in commercial housing communities (11.11), the highest Breteau index (BI) was in construction sites (21.14), the highest Aedes route index (RI) was in construction sites (8.33 places/km), and the highest adult mosquito density (AMD) was recorded in a construction site[0.97/(lamp·night)]. There were positive correlations between BI and HI, between BI and MOI, and between BI and RI in the general environment (r=0.665, 0.517, and 0.614, all P<0.05). In commercial housing residential areas, a positive correlation was found between BI and HI, between BI and MOI, and between HI and MOI (r=0.991, 0.926, and 0.905, all P<0.05). In resettlement residential areas, BI and HI were positively correlated (r=0.958, P=0.001). In rural cooperatives, a positive correlation was found between BI and HI, between HI and MOI, between RI and AMD, and between AMD and MOI (r=0.995, 0.818, 0.837, and 0.813, all P<0.05). In other residential areas (urban villages, enterprise dormitories, construction sites, and school dormitories), BI was positively correlated with RI (r=0.992, P=0.001).Conclusion Duplicated monitoring with both BI and HI should be avoided in residential areas such as commercial housing residential areas, resettlement residential areas, and rural cooperatives. Duplicated mosquito monitoring with both BI and RI should be avoided in urban villages, enterprise dormitories, construction sites, school dormitories, and other residential areas with large external environment. Duplicated monitoring with both BI and MOI should be avoided in commercial housing residential areas. Both BI and MOI should be selected to complement each other for monitoring Aedes mosquito the resettlement residential areas, rural cooperatives, and other residential types.
