Abstract:

Objective To compare the results of fixed and mobile monitoring for optimizing the surveillance program for Aedes albopictus. Methods From May to October 2012, 5 fixed sites were selected for the larval population monitoring of Ae. albopictus; meanwhile, at least 7 villages were selected as mobile monitoring sites in each month. Fifty households were monitored in each village. The data at each monitoring site were collected, and the breteau index (BI), container index (CI), and house index (HI) were calculated. The monitoring data obtained by the two methods were subject to analysis of variance and correlation analysis. Results The average BI, CI, and HI at fixed monitoring sites were 5.20, 15.55%, and 4.53%, respectively. BI varied slightly in different months, but the value in October was significantly lower than those in other months. The average BIs in Jiulian of Jiangdong, Qingsu of Yiting, Jiangwan of Choujiang, Siqian of Houzhai, and Dongqianwang of Choucheng were 4.67, 2.33, 4.67, 8.00, and 6.33, respectively. The analysis of variance showed that the average BI at different fixed monitoring sites varied insignificantly from May to October. The Pearson correlation analysis revealed no significant correlation between the BIs in different months at each monitoring site. The average BIs at mobile monitoring sites from May to October were 5.43, 8.60, 2.00, 5.00, 1.60 and 1.64, respectively. In each month, the average BI at fixed monitoring sites was not significantly correlated with that at mobile monitoring sites. Conclusion Fixed monitoring can reflect the temporal change in the density of Ae. albopictus, and mobile monitoring can expand the monitored area and improve the representativeness of monitoring data. The two methods can be combined to improve the monitoring of Ae. albopictus.

摘要：

目的 通过流动监测和固定监测在现场的平行性试验，分析2种方式对白纹伊蚊的监测效果，为优化白纹伊蚊监测方法提供科学依据。方法 2012年5－10月选择5个固定监测点开展白纹伊蚊幼虫密度监测，同时每个月选择至少7个流动村进行平行监测，每个村监测50户居民，收集每个监测点资料，计算布雷图指数（BI）、容器指数（CI）和房屋指数（HI），对2种方式的监测数据进行方差分析、相关性分析等。结果 固定监测点5－10月监测的平均BI、CI和HI分别为5.20、15.55%和4.53%，不同月份的BI差别较小，只有10月的BI明显小于其他月份；江东九联、义亭青肃、稠江江湾、后宅寺前和稠城东前王的平均BI分别为4.67、2.33、4.67、8.00和6.33，经方差分析，不同固定监测点各月份的平均BI差异无统计学意义。对不同监测点不同月份的BI进行Pearson相关性分析，各监测点不同月份的BI无显著相关。流动监测点5－10月各月的平均BI分别为5.43、8.60、2.00、5.00、1.60和1.64。经相关性分析，固定监测和流动监测每月的平均BI无显著相关。结论 固定监测可以反映白纹伊蚊密度的时间变化趋势，流动监测可以扩大监测范围，提高监测数据的代表性，二者结合可以更科学地进行白纹伊蚊监测。
