摘　　要：气象因子是影响昆虫种群数量最重要的因素之一。本研究采用马来氏网收集法,2014年5月-2015年10月连续两年对青岛市重要花生害虫西花蓟马种群数量与气象因子间的关系进行了研究,结果如下:相关分析表明,最大风速风向、极大风速风向、最低气温、日最低地表气温、平均相对湿度等5因子与西花蓟马数量密切相关;偏相关分析表明,平均地表气温、极大风速、平均气温、极大风速风向、平均日降雨量、平均相对湿度、最高气温、平均风速等8因子与西花蓟马数量明显相关;通径分析表明,各气象因子都直接或间接影响西花蓟马数量,直接作用大于间接作用的气象因子为平均气温和平均日降雨量,间接作用大于直接作用的气象因子是最低气温和日最低地表气温,最大风速与西花蓟马数量变动直接和间接作用均呈负相关。通径分析决策系数由大到小依次为最大风速、平均相对湿度、平均日降雨量、极大风速、平均风速。综合分析表明,与西花蓟马数量变动密切相关的气象因子为最大风速、极大风速与风向、平均相对湿度、平均日降雨量、最高气温和平均地表气温。Meteorological factors are one of the most important factors affecting the insect population.In this study,the relationship between the meteorological factors and the population number of Frankliniella occidentalis,which is an important peanut pest in peanut field in Qingdao,with the method of Malay network collection for two consecutive years from May 2014 to October 2015 were studied.The correlation analysis results showed that the five factors of the maximum wind speed direction,the extreme wind direction,the minimum air temperature,daily minimum surface temperature,average relative humidity are closely related to the change of the number of Frankliniella occidentalis;the results of partial correlation analysis show that the eight factors,including the average surface temperature,extreme wind speed,average air temperature,extreme wind speed direction,average daily rainfall,average relative humidity,maximum air temperature and average wind speed are significantly correlated with the quantity dynamics of Frankliniella occidentalis.The results of path analysis showed that all meteorological factors directly or indirectly affect the population variation of Frankliniella occidentalis.The direct effect is greater than the indirect effect of meteorological factor with average temperature and the average daily rainfall.The indirect effect is greater than the direct effect meteorological factor with minimum air temperature and daily minimum surface temperature.The maximum wind speed is negatively correlated with both direct and indirect effects of population variation of Frankliniella occidentalis.The decision coefficient of path analysis in turn is maximum wind speed,average relative humidity,average daily rainfall,extreme wind speed and average wind speed.The comprehensive analysis showed that the main meteorological factors closely related to the quantity dynamics of Frankliniella occidentalis are extreme wind speed,extreme wind speed direction,average relative humidity,average daily rainfall,maximum air temperature
