Methods From July 12 to October 18, 2020, 60 mosquito ovitraps were placed in Zhujing and Langxia towns of Jinshan district, Shanghai, and 50 mosquito ovitraps were placed in Tinglin town each week to monitor the density of Ae. albopictus, and a database was established based on the data of the adult mosquitoes captured. The Skewness-Kurtosis test was used to test the normal distribution of adult Ae. albopictus mosquitoes captured by each mosquito ovitrap; the negative binomial goodness of fit was used to test whether the adult Ae. albopictus mosquitoes captured obeyed the negative binomial distribution, and the weighted estimation method in the moment method was used to calculate the common kc value of negative binomial distribution. Stata 14.0 software was used for statistical analysis. Results A total of 2 171 mosquito ovitraps were collected for the 13 times of monitoring in Jinshan district, and 767 adult Ae. albopictus mosquitoes were captured. In Zhujing, Langxia, and Tinglin towns, the mean of adult mosquitoes was higher than the median, and the variance was greater than the mean, which suggested aggregated distribution. The Skewness-Kurtosis test showed P<0.001, indicating positively skewed distribution. The goodness of fit test of negative binomial distribution showed a chi-square value of 6.389 (P=0.172), and the adult Ae. albopictus mosquitoes in the mosquito ovitrap obeyed negative binomial distribution, with a kc value of 0.522 (χ2= 18.297, P=0.107). Conclusion The adult Ae. albopictus mosquitoes captured by mosquito ovitraps show aggregated and positively skewed distribution, which obeys negative binomial distribution. %U http://www.bmsw.net.cn/EN/10.11853/j.issn.1003.8280.2021.04.020
