广东登革热媒介白纹伊蚊孳生容器类型及其防制效果研究

OBSERVATION ON BREEDING CONTAINER TYPES OF VECTORIAL AEDES ALBOPICTUS OF DENGUE AND THEIR CONTROL EFFECTS IN GUANGDONG PROVINCE

目的 :研究广东省登革热媒介白纹伊蚊的孳生容器类型 ,进一步做好对登革热病的防制。方法 :按系统随机调查法 ,以抽样流行过登革热的 4个地区为调查对象 ,针对不同孳生容器类型 ,采用不同处理方法处理孳生地为主的综合防治措施。。结果 :白纹伊蚊阳性孳生容器除山区外 ,均以废瓶罐和花卉型积水容器为最普遍。其容器类型分布 ,城区以花卉型为主 ,农村以废瓶罐型为主 ,山区以特殊容器 (腌菜缸周围边积水 )型为主 ,乡镇兼有花卉和废瓶罐两型。根据不同种类容器 ,应用不同处理方法并结合综合防治措施 ,均获得满意效果。结论 :采用不同方法处理孳生地为主的综合防制措施 ,可将蚊媒控制在不足为害的水平。

Objective:To study the breeding containers of dengue vectors and the control strategy in Guangdong province. Methods:Investigation on breeding containers of Aedes albopictus was made through random and systematic sampling methods in four districts of dengue fever epidemic in Guangdong province in June-December from 1996 to 1998. Results:Among different kinds of water containers,the waste water jars,bottles and tins,etc, and water vases in which the flowers and plants grown, were the most common breeding containers except in the mountains. The distribution of water containers showed that the water vases were the major breeding place in the city proper and that the waste water jars in the rural area, as well as the pickle jars in the mountains. However, both water vases and wasts jars were the major breeding places in the town. After applying different treatment methods depending on different kinds of breeding containers and combining with other synthetic measures, satisfactory result were obtained. Conclusion: The synthetic measures by using mainlg different treatment methods on breeding places may control vector Aedes albopictus breeding.
