摘要:

目的 调查河南省永城市的蚊种构成、密度、季节消长及其分布,了解该地区优势蚊种及其活动规律,为防控蚊媒疾病提供依据。方法 根据不同地理方位选择3个乡镇作为调查点,于2010年7-10月采用诱蚊灯法在人房外、户外和牲畜棚等不同生境开展蚊类调查,每月2次,对捕获的蚊类进行形态学鉴定、记录,并利用Excel 2007和SPSS 20.0软件进行数据分析。结果 共捕获蚊虫20 684只,隶属4属5种,平均蚊密度为34.08只/(灯·夜);三带喙库蚊为优势蚊种,占捕获总数的54.12%。牲畜棚蚊密度最高,达50.58只/(灯·夜),人房外和户外环境蚊密度差异无统计学意义,3种生境蚊密度差异有统计学意义(F=74.450,P<0.01)。蚊密度7月开始增高,7月下旬为活动小高峰,9月达活动最高峰,10月开始下降。任湖和孟庄村蚊密度于9月上旬达最高峰,呈单峰分布,以任湖村蚊密度最高;3个乡镇的蚊虫数量和蚊种构成差异有统计学意义(χ2=2 033.097,P<0.01)。结论 永城市蚊虫分布依生境和地方性特征而不同,可根据不同地区、生境及蚊种季节变化趋势,采取针对性的防蚊灭蚊措施开展蚊虫防治工作。

Abstract:

Objective To decide the predominant mosquito species in Yongcheng city, and their natural occurrence, density, seasonal fluctuation, and habitat distribution. The results will guide the vector management in this area. Methods Light-trapped method was used twice a month in three towns which lies in different direction in Yongcheng area. Dwellings, houses premises, and livestocks were selected as the surveillance sites in each town. Excel 2007 and SPSS 20.0 were used for data analysis. Results The total mosquito number obtained in 2010 were 20 684 with the average density 34.08/(trap·night). Culex tritaeniorhynchus took up to 54.12%, which was the predominent species. The mosquito density in livestocks was 50.58/(trap·night) which was the highest; the mosquito density around dwellings and their premises had no significant difference. Mosquito density showed statistical significance in 3 surveillance habitats (F=74.450, P<0.01). Mosquito density began to increase in July, reach a small peak activity in late July, and reached the highest peak activity in September, followed a decline in October. The mosquito density in Renhu and Mengzhuang villages reached the peak in early September, showed a unimodal peak activity. Renhu had the highest mosquito density. Three towns showed statistically significant differences in mosquito species and their density (χ2=2 033.097, P<0.01). Conclusion The distribution of mosquitoes in Yongcheng city varied according to habitat and village characteristics, then the mosquito prevention and control work should be based on the mosquito distribution in different habit, different village, and seasonal performance by species in this area.

Key words: Light-trapped method, Mosquito species composition, Distribution, Seasonal fluctuation
