目的通过监测,了解达州市蚊类构成及蚊密度消长情况,为保障人民身体健康,消除疾病传播媒介工作提供可靠的科学依据。方法对捕获的成蚊进行分类鉴定,并统计分析。结果共捕获成蚊3181只,发现蚊种4类。优势种为致倦库蚊和三带喙库蚊,蚊密度7月达到最高峰,6~8月蚊密度维持在较高水平。各生境蚊密度以农村为高。结论全年蚊密度消长趋势基本呈单峰曲线,提示在乙脑、疟疾等传染病流行季节,需加强防蚊、灭蚊工作,大力开展除四害活动。
Objective To understand the changes of mosquito composition and mosquito density in Dazhou through monitoring so as to provide a reliable scientific basis for protecting the people’s health and eliminating the disease media. Methods The captured adult mosquitoes were classified and identified and statistically analyzed. Results A total of 3181 adult mosquitoes were captured and 4 mosquito species were found. The dominant species were Culex pipiens quinquefasciatus and Culex tritaeniorhynchus, mosquito density reached its peak in July, mosquito density maintained at a high level from June to August. The density of habitat mosquitoes in rural areas is high. Conclusion The trend of decline and growth of mosquito density in the whole year is basically single peak curve, suggesting that in the epidemic season of infectious diseases such as Japanese encephalitis and malaria, mosquito control and mosquito control should be intensified to carry out the activity of removing four victims.
