目的 了解山东省临沂市白纹伊蚊幼蚊密度和季节消长规律，评估其传播登革热风险，预防登革热发生和流行。方法 应用布雷图指数（BI）法进行媒介伊蚊幼蚊监测和评估；应用SPSS 20.0软件进行统计学分析，分类资料比较用χ2检验。结果 2018-2020年白纹伊蚊幼蚊BI均值为14.98，各年度依次分别为18.97、10.79和13.88；兰陵县BI高于河东区和沂南县。农户、废旧物品处3年平均BI分别为33.03和27.00，有区域流行风险；居民区为14.36，有暴发风险；工地和公园分别为9.31和9.27，有传播风险；医院为4.33，无风险。积水容器幼蚊阳性率为21.72%，以废旧轮胎阳性率最高为40.34%。2018-2020年白纹伊蚊幼蚊BI峰值分别出现在8月（54.63）、8月（40.00）和7月（47.51）；6-8月易发生登革热区域流行，5、9和10月有传播风险，3、4和11月无风险。结论 临沂市白纹伊蚊密度较高，存在登革热暴发和区域流行的风险，应加强媒介伊蚊监测和风险管控。
Objective To investigate the density and seasonal variation of Aedes albopictus larvae in Linyi, Shandong province, China and assess the transmission risk of dengue fever, and to prevent the occurrence and epidemic of dengue fever. Methods The Breteau index (BI) was adopted to monitor Ae. albopictus larvae. SPSS 20.0 software was used for statistical analysis, and Chi-squared test was used for comparison of categorical data. Results The BI values of Ae. albopictus larvae were 18.97, 10.79, and 13.88 from 2018 to 2020, respectively, with a mean value of 14.98. The mean BI was higher in Lanling county than in Hedong district and Yinan county. In the three years, the mean BI of households and waste collection stations was 33.03 and 27.00, respectively, indicating a regional epidemic risk of dengue fever; the mean BI in residential areas was 14.36, indicating an outbreak risk of dengue fever; the mean BI of construction sites and parks were 9.31 and 9.27, respectively, indicating a risk of transmission; the mean BI was 4.33 in hospitals, suggesting no risk of dengue fever. The positive rate of mosquito larvae in total water containers was 21.72%, and the waste tires had the highest positive rate of 40.34%. The BI of Ae. albopictus larvae peaked at 54.63 in August 2018, at 40.00 in August 2019, and at 47.51 in July 2020. There was a high regional epidemic risk of dengue fever from June to August, a transmission risk in May, September, and October, and no risk in March, April, and November. Conclusion There is a high density of Ae. albopictus mosquitoes in Linyi, indicating an outbreak or regional epidemic risk of dengue fever. Aedes surveillance and risk control should be strengthened.
