摘要: 目的 掌握云南省腾冲市城区蚊种构成和空间分布、种群密度及季节消长情况,为蚊虫防治提供科学依据。方法 采用诱蚊灯法进行成蚊调查,布雷图指数(BI)法进行伊蚊幼虫调查,使用Fχ2(或Fisher确切概率法)检验对调查结果进行统计分析。结果 2018-2020年共捕获成蚊5属12种61 810只,城区优势蚊种为致倦库蚊和三带喙库蚊,城市周边地区优势蚊种为中华按蚊和三带喙库蚊。城区周边牛棚蚊虫平均密度为2 183.32只/(灯·夜),医院、学校、公园和居民区分别为12.29、4.93、4.29和2.68只/(灯·夜),伊蚊幼蚊调查11 986个容器,阳性容器80个,均为白纹伊蚊幼蚊,平均BI为0.66。结论 初步掌握了腾冲市城区蚊种构成和空间分布、种群密度、季节消长情况,进行蚊虫防制时,应根据蚊虫密度季节消长情况及蚊虫孳生环境类型,采取不同的控制措施。

Abstract: Objective To investigate the species composition, spatial distribution, population density, and seasonal fluctuation of mosquitoes in the urban area of Tengchong, Yunnan province, China, and to provide a scientific basis for mosquito prevention and control. Methods Adult mosquitoes were captured by the light trap method. Aedes albopictus larvae were investigated using the Breteau index (BI). The F test and Chi-squared test (or Fisher's exact test) were used for data analysis. Results A total of 61 810 adult mosquitoes were captured from 2018 to 2020, involving 12 species of 5 genera. The dominant species were Culex pipiens quinquefasciatus and Cx. tritaeniorhynchus in the urban area, and Anopheles sinensis and Cx. tritaeniorhynchus in the suburban area. The average mosquito density was 2 183.32 mosquitoes/light·night in cattle sheds in the suburban area, 12.29 mosquitoes/light·night in hospitals, 4.93 mosquitoes/light·night in schools, 4.29 mosquitoes/light·night in parks, and 2.68 mosquitoes/light·night in residential areas. A total of 11 986 containers were examined for Aedes larvae. There were 80 positive containers, all of which were positive for Ae. albopictus larvae. The average BI was 0.66. Conclusion The species composition, spatial distribution, population density, and seasonal fluctuation of mosquitoes in the urban area of Tengchong are preliminarily understood. Control measures should depend on the seasonal fluctuation of mosquito density and the breeding environment of mosquito.
