目的了解云南省腾冲市蚊媒组成及分布特点,为腾冲市虫媒传染病防控提供科学依据。方法 2012年7月和2013年8月,根据腾冲市地理位置选取南部(新华、蒲川)、中部(中和、清水)和北部(滇滩、固东)6个乡(镇)9个村,采用诱蚊灯通宵捕蚊,对所获蚊虫进行鉴定、解剖、计数和统计学分析。结果共捕获蚊虫14 266只,隶属于2亚科8属11亚属31种,优势蚊种北部地区为中华按蚊(1 729/3 440,50.26%),中部地区为昆明按蚊(990/2 888,34.28%),南部地区为三带喙库蚊(3 626/7 928,45.74%)。结论腾冲市蚊媒组成及分布较为复杂,存在多种传染病传播媒介。因此,制定虫媒传染病的防控措施要因地制宜。
Objective To understand the composition and distribution of mosquito vectors in Tengchong, Yunnan Province, and to provide a scientific basis for prevention and control of vector-borne diseases in Tengchong. Methods In July 2012 and August 2013, nine villages (towns) in the south (Xinhua and Puchuan), central (Zhonghe and Qingshui) and northern (Diantan and Guandong) townships were selected according to the geographic location of Tengchong City , The use of mosquito lamp all night catch mosquitoes, mosquitoes were identified, anatomical, counting and statistical analysis. Results A total of 14 266 mosquitoes were captured, belonging to 11 subgenuses of 8 genera and 2 subfamilies. The dominant mosquito species were Anopheles sinensis (1 729/3 440 and 50.26%) in the northern area and Anopheles mosquitoes (990 / 2 888,34.28%), Culex tritaeniorhynchus (3 626/7 928,45.74%) in the southern area. Conclusion The composition and distribution of mosquito vectors in Tengchong City are quite complicated, and there are many kinds of vectors for transmitting infectious diseases. Therefore, the development of prevention and control of vector-borne diseases should be adapted to local conditions.
