摘要: 目的 了解青海省部分地区不同季节的蚊密度,探究蚊密度与气象因素之间的关系。方法 利用Excel 2022软件对2018-2021年青海省5个监测点的蚊密度进行圆形分布法的计算,并推算各监测点蚊密度高峰日和高峰期;利用SPSS 22.0软件对青海省西宁、格尔木和玉树市的蚊密度与相关气象因素进行多元线性回归分析。结果 青海省调查点的蚊虫季节消长高峰日为7月19日,高峰期为6月10日-8月28日;蚊密度和气象因素回归方程为y=-2.19+0.47x1+0.01x3+0.02x4x1:月平均气温;x3:月平均相对湿度;x4:月平均气压)(F=20.613,P<0.001)。在海拔3 700 m的玉树市发现有蚊虫孳生。结论 青海省部分地区蚊密度与气温、相对湿度、气压之间存在一定相关关系,且蚊密度高峰期基本都集中在7月中旬。

Abstract: Objective To study the seasonal distribution of mosquito density and explore the relationship between mosquito density and meteorological factors in some areas of Qinghai Province, China.Methods The data on mosquito density of five surveillance points of Qinghai Province from 2018 to 2021 were analyzed using the circular distribution method to calculate the peak day and peak period of mosquito density at each surveillance point. A multiple linear regression analysis was conducted to determine the relationship between mosquito density and meteorological factors in Xining, Golmud, and Yushu of Qinghai Province with SPSS 22.0.Results The peak day of seasonal fluctuations of mosquitoes of surveyed points in Qinghai Province was July 19, and the peak period was from June 10 to August 28. The regression equation for mosquito density and meteorological factors was y=-2.19+0.47x1+0.01x3+0.02x4 (x1, mean air temperature; x3, monthly average relative humidity; x4, monthly mean air pressure) (F=20.613, P<0.001). Mosquitoes have been found breeding in Yushu City with an altitude of 3 700 meters.Conclusions There is a certain correlation between the mosquito density in some areas of Qinghai Province and the local monthly average temperature, monthly average humidity, and monthly average air pressure, and the peak period of mosquito density is basically concentrated in mid July.
