摘要
应用主分量分析方法对贵德蝠蛾 (HepialusguideraYan)各虫态、天敌、温度和湿度因子进行了分析 ,由此了解到影响贵德蝠蛾种群数量变动的主导因子是湿度 ,其次是天敌和温度。
Key ecological factors of population system of Hepialus guidera Yan were analysed from its′ each stage and natural enemies, temperature and relative humidity in the soil with the priciple component analysis method Result showed that key factor of affecting population dynamic, H guidera is soil relative humidity,which can provide important reference for studying further in the laboratory
