Objective To analyze the monitoring results of mosquito ovitraps in different residential communities in Xuhui District,Shanghai,so as to provide theoretical basis for developing scientific and efficient density control strategies for Aedes albopictus in residential communities,and to reduce the risk of dengue fever transmission in the local area.Methods Use mosquito ovitraps to monitor mosquito density every two weeks in 168 residential communities from June to October,record the positive rate of mosquito ovitraps of 3 types of residential buildings in 8 monitoring rounds.The Shapiro-Wilk test was used to analyze the normal distribution of the positive rate of mosquito and egg attractants,the Kruslal-Wallis test and Mann-Whitney U test were used to analyze the non parametric test of the positive rate of mosquito ovitraps,Spearman correlation analysis was used to analyze the correlation between the positive rate of mosquito ovitraps and the green coverage ratio,as well as between the positive rate of mosquito ovitraps and property fees.Results The average positive rate of mosquito ovitraps was 5.17%;among the 8 monitoring rounds,the highest positive rate of mosquito ovitraps was 6.62%in the 3rd round(July),the lowest was 2.98%in the 8th round(October),and it slightly increased to 4.92%in the 6th round(September);among the three types of residential communities,the average positive rate of mosquito ovitraps in ordinary communities was 5.80%,which was higher than that in high-rise building communities at 3.94%,and the difference was statistically significant(P<0.001),in low-density communities,positive rates of mosquito ovitraps was 5.10%,and the difference was not statistically significant.Meanwhile,the positive rate of mosquito ovitraps was significantly negatively correlated with property fees,and had no correlation with green coverage ratio.Conclusion The positive rate of mosquito ovitraps in residential communities reached its peak in July,followed by a second peak in September.The average positive rate of mosquito ovitraps in ordinary residential areas was significantly higher than that in high-rise building communities,and the positive rate was significantly negatively correlated with property fees.Each residential community can carry out Aedes albopictus contro method based on the situation of property personnel.
