| 摘 要： | 本文应用二次通用旋转组合设计的方法进行了蚜茧蜂对麦蚜寄生能力的研究，得出了蚜茧蜂的寄生量模型：Ｙ＝９１．４０＋４３．６２Ｘ１＋２０．２７Ｘ２＋７．２５Ｘ１Ｘ２－１６．８３Ｘ１＾２＋３．４３Ｘ２＾２。并对模型进行了分析，表明对总寄生量的影响因素中麦蚜密度的大小大于蚜茧蜂本身密度的大小。在试验密度范围内，蚜虫和蚜茧蜂干扰作用不明显，且有相互促进的作用，但增加速度相同。

| Abstract: | By using quadratic regression common rotation design, the parasitizing action of aphidparasites on wheat aphids was studied under the experimental condition. The parasition model ofaphid parasites to wheat aphids was obtained as: Y = 91.40 + 43. 62X1 + 2O. 27X2 + 7. 25X1X2 -16.83X + 3 .43X2. The control efficiency analyzing on this model indicated that increasing ofwheat aphid density has grater effect on total paratisic amount of aphid parasites than that of in-creasing of aphid parasites. Wheat aphids and aphid parasites have little interference in this experi-ment densities, they even promote each other, but the increase speed is the same. |
