供水系统摇蚊的生长繁殖规律与预警预防

Growth, Reproduction Regularity and Prediction of Chironomid Midge in Water Supply System

对深圳地区给水处理厂及其他地点摇蚊的种属进行了鉴定,确定了优势种;通过实验室人工繁殖,总结出影响摇蚊生长繁殖的主要因素;提出沉淀池是摇蚊生长的不稳定环境,清洗沉淀池对其消长规律有明显影响;通过对摇蚊幼虫来源、环境和水质参数、构筑物中摇蚊成虫和幼虫密度的监测,可对摇蚊爆发进行预警预报,从而采取适宜的预防措施。

Species of chironomid midge were identified as well as the superior ones in water works and other places in Shenzhen. Main factors that influenced the reproduction and growth of chironomid midge were determined by means of artificial breeding in the laboratory. Sedimentation tank is an unstable environment for the growth of chironomid midge and tank washing has a significant impact on its growth. Monitoring of larva sources, environmental and water quality parameters, density of larva and adult chironomid midge in structure will enable to foresee booming of chironomid midge and adopt corresponding preventive measures.
