目的掌握蒙自市城区及市郊蚊类群落组成及其特征,为虫媒传播疾病防控提供科学依据。方法采用灯诱法调查成蚊,计算密度,同时调查伊蚊幼虫孳生容器,计算布雷图指数。结果捕获成蚊2属3种共21 799只。5个调查点成蚊平均密度为22.24只/(盏·夜)。包括流行性乙型脑炎主要传播媒介三带喙库蚊9 816只,占45.03%,但优势种为致倦库蚊10 860只,占49.82%。幼虫调查在轮胎收购点等特殊场所发现登革热传播媒介白纹伊蚊,布雷图指数(BI)0.04。结论蒙自市区蚊种少,但成蚊密度高,发现有流行性乙型脑炎和登革热传播媒介,应持续开展媒介监测。 Objective To understand the composition and characteristics of mosquito communities in urban areas and suburbs of Mengzi City and provide a scientific basis for the prevention and control of insect-borne diseases. Methods Light trap method was used to investigate adult mosquitoes and calculate density. At the same time, the mosquito larvae were surveyed to calculate the Brettiler index. Results A total of 21 799 mosquitoes from 2 genera were captured. The average density of adult mosquitoes in the five survey sites was 22.24 / (light · night). Including 9 816 (three) Culex tritaeniorhynchus, the major vectors for Japanese encephalitis, accounting for 45.03% of the total, while 10 860 predominant species were Culex pipiens quinquefasciatus (49.82%). Larvae survey Dengue vectors such as Aedes albopictus and Bretzeed Melancholy (BI) 0.04 were found at special sites such as tire purchases. Conclusion There were few mosquito species in the urban area of ​​Mengzi, but the density of adult mosquitoes was high. There was epidemic encephalitis and dengue vector found, and media monitoring should be continued.
