【摘要】 日光蜂对苹果绵蚜的功能反应符合HollingⅡ型模型,其数学模型为:Na=0.1246No/(1+0.1246×0.0127No)。日光蜂寄生苹果绵蚜的数量随苹果绵蚜密度的增加而增加,但日光蜂寻找效应随苹果绵蚜密度的增加而降低,其数学模型为:E=0.1246/(1+0.1246×0.0127No)。日光蜂的最大寄生量和最佳寻找密度分别为50.40和194.46头。日光蜂寻找效应随其自身密度的增加而降低,其数学模型为:E=0.1698P-1.0639。不同温度条件下日光蜂对苹果绵蚜的寄生量有差异,在22℃时寄生量最高。更多还原

【Abstract】 The Aphelinus mali is a mainly parasitism of Eriosoma lanigerum,and effectively control the damage of Eriosoma lanigerum in the apple orchard.Functional response and searching efficiency of the Aphelinus mail were determined in the laboratory.The result showed that the functional response was belong to Holling,’s type Ⅱ;the mathematical model of functional response was Na=0.1246No/ （1+0.1246×0.0127No）;the daily maximum numbers of parasitism and the optimal searching efficiency was 50.40 and 194.46 aphids,respectively;the searching efficiency decreased with the increase of Eriosoma lanigerum density and Aphelinus mali density,the mathematical model were E=0.1246/（1+0.1246×0.0127No） and E=0.1698P^-1.0639,respectively.The result showed that the suitable temperature to parasitism was about 22℃.更多还原
