摘要: 目的 对某室外污水处理试验系统各单元中淡色库蚊幼虫孳生情况进行调查,并探究气象因素和水质对其孳生的影响。方法 于2015年5月10日至11月27日和2016年4月4日至8月31日,利用勺捕法采集某污水处理试验系统的蚊幼虫,并记录采样当天的气象因素;对系统中浮床水质的总氮、总磷、总有机碳、五日生化需氧量和化学需氧量进行测定分析。结果 淡色库蚊幼虫密度在最低气温> 13.0℃开始增加,春末夏初气温19.0~28.0℃为淡色库蚊幼虫最适宜生存温度,蚊幼虫的孳生达到最高水平,在最高温度> 31.0℃后锐减。蚊幼虫密度的快速增长期伴有较多的阴雨天气,衰减期伴有长时间无降雨天气或连续强降雨。蚊幼虫密度与总氮、总磷、总有机碳、五日生化需氧量和水质综合污染指数均呈正相关。结论 水质、最低气温、最高气温和降雨等对淡色库蚊幼虫的孳生均有影响,以最高气温影响最明显。

Abstract: Objective Investigating the quantity and variation of Culex pipiens pallens larvae to weather condition, and water quality in an outdoor water treatment testing system in Shanghai, China. Methods Collecting mosquito larvae and pupae during May 10th to November 27th in 2015 and April 4th to August 31th in 2016, and recording the daily temperature, precipitation, weather, analyzing the TN, TP, TOC, BOD5 of water samples at the same time. Results The density of larvae started to increase when the daily minimum temperature reached 13.0℃, peaked when the daily temperature ranging 19.0 to 28.0℃, and collapsed after the daily maximum temperature higher than 31.0℃. The rapid increasing of density was accompanied with wet or cloudy weather, while the decreasing period was accompanied with sunny day or heavy rainfall. The correlation of Cx. pipiens pallens larvae density and TN, TP, TOC, BOD5, comprehensive pollution index of water quality was relatively positive. Conclusion Water quality, daily minimum and maximum temperatures and weather have impact on the breeding of Cx. pipiens pallens, especially daily maximum temperature.
