中文摘要：

         采用计算机模拟混色技术，结合正交设计，定量测定了有翅桃蚜Myzus persicae（Sulzer）对青（C）、洋红（M）、黄（Y）和黑（K）4色成分模式混合色的选择性反应。第1组L25(5⁶)试验结果表明，因子效应顺序为：Y﹥M﹥K﹥C。最佳理论混合色参数为C=25%、Y=25%、M=100%、K=0，模拟色板的叶色竞争系数（LCC）达77.78%。第2组L16(4⁵)正交试验结果表明，当C、M、Y、K分别在10%～ 40%、10%～ 40%、85%～ 100%和0～ 15%区间变化时，对所有处理的叶色竞争系数均无显著影响。模拟色板叶色竞争系数与黄色成分和黑色成分的回归方程分别为LCC＝0.0390Y²-0.1875Y+0.5591（R²＝0.9913）和LCC＝0.0163K²-0.1237K＋0.6176（R²＝0.7926）。

英文摘要：      Quantitative bioassays on selection responses of alate Myzus persicae（Sulzer） to CMYK，the colour mixture of cyan, magenta, yellow and black, were conducted using computer simulated colours, designed with the orthogonal optimization method. Results of the first experiment using L25(5⁶) array design showed that the factorial effects were as follows: Y>M>K>C. The best theoretical mixed colour parameters were C=25%, Y=25%, M=100%, K=0, and the leaf colour competitive coefficient (LCC) of alate M. persicae to this mixed colour reached up to 77.78%. Results of the second experiment using L16(4⁵) array design showed that all the CMYK parameters have not significant effect on LCC values of the simulated colour, when the C, M, Y and K values were in the ranges of C∈［10%, 40%］, M∈［10%, 40%］, Y∈［85%, 100%］, and K∈［0, 15%］ respectively. The regression equation of LCC with yellow component and black component was LCC＝0.0390Y²-0.1875Y＋0.5591 (R²＝0.9913) and LCC＝0.0163K²-0.1237K＋0.6176 (R²＝0.7926), respectively.
