| 摘 要： | 研究了百合上桃蚜种群数量季节变动动态。结果表明．为害百合的桃蚜主要来源于周围植物迁入的有翅蚜,桃蚜种群在5～6月达最高峰。气候因子旬平均温度和降雨量明显影响桃蚜种群数量变动．其回归关系式分别为：Y1=13．9757 0．007198X1—0．0000007572X1^2和Y2=10．2812 0．02267X2 0．0000032586X2^2。桃蚜种群数量变动与天敌数量变动呈密切正相关．其回归关系式为：Y3=635．3057 1．5661X3-0．00009311X2^2。

| Abstract: | The population dynamic of Myzus Persicae on Lilium Speciosum was studied. M. persicae on lily was mainly alar that came from other host plant around the vicinity. There was a peak from May to June. Population dynamic of M. persicae was significantly influenced by climatic factors such as average temperature and rainfall. The influence of climatic factors on population dynamic of M. persicae could be described by the equation: Y _1= 13.9757+0.007198 X _1-0.0000007572 X_1 ~2 and Y _2=10.2812 +0.02267 X _2+0.0000032586 X_2 ~2 , respectively. The significant influence of natural enemies on population dynamic of M. persicae could be described by the equation: Y_3 =635.3057+1.5661 X_3 -0.00009311 X_3 ~2 . |
