【摘要】:目的探索和分析同一区域不同季节及不同昼夜监测时段蚊虫种群动态的差异性。方法选取中心城区蚊虫较容易出现的公园和绿化区域环境类型(上海市人民广场及人民公园区域),按照地理分布设置5个监测点,每天分为3个连续时段,连续224 d采用CO2诱捕法进行成蚊监测。结果上海市城区中心地带不同蚊种的月份分布差异有统计学意义(χ2=187.923,P0.01),淡色库蚊为最优势蚊种〔13.35只/(d·台)〕;季节分布,淡色库蚊高峰期分布于5-6月〔19.93和28.19只/(d·台)〕,白纹伊蚊和三带喙库蚊高峰期在7月〔10.77和8.79只/(d·台)〕;昼夜节律方面,成蚊密度在3个时段的分布由高到低依次为夜晚和清晨时段(20:00至次日08:00)、傍晚时段(16:30-20:00)和白天时段(08:00-16:30);白天时段白纹伊蚊为优势种(构成比为65.70%),其他2个时段淡色库蚊为优势种(构成比分别为78.14%和66.05%)。结论不同季节及不同昼夜时段成蚊密度和种群构成差异有统计学意义,原因主要由不同成蚊的生态习性决定,研究中还发现较多与文献记载存在明显差异的现象,认为可能与上海市的城市环境及城市光污染有关,该影响因素有待进一步验证。
[Abstract]:Objective to explore and analyze the difference of mosquito population dynamics in different seasons and different diurnal monitoring periods in the same area. Methods the environmental types of parks and greening areas (Shanghai people's Square and people's Park) were selected, and 5 monitoring points were set up according to geographical distribution, which were divided into 3 consecutive periods every day. The adult mosquitoes were monitored by CO2 trapping method for 224th days. Results the monthly distribution of different species of Culex pipiens in downtown area of Shanghai was significantly different (蠂 2 187.923 P0.01g, Culex pipiens pallens was the most dominant species, 13.35 / d / d, and seasonal distribution, peak of Culex pipiens pallens was 19.93 and 28.19 / d in May-June). The peak periods of Aedes albopictus and Culex tritaeniformis were 10.77 and 8.79 in July. The distribution of adult mosquito density from high to low was 20: 00 in the evening and 20: 00 in the morning, 16: 30-20: 00 in the evening, and 08: 00-16: 30 in the daytime. Aedes albopictus was the dominant species in the daytime (the composition ratio was 65.70%, the other two periods were Culex pipiens pallens). The composition ratio was 78.14% and 66.05%, respectively. Conclusion there are significant differences in the density and population composition of adult mosquitoes in different seasons and different diurnal periods. The reasons are mainly determined by the ecological habits of different adult mosquitoes. It is suggested that it may be related to the urban environment and urban light pollution in Shanghai, and the influencing factors need to be further verified.
