根据３年田间试验结果，对所设计的６种害虫３种不同组合的棉花多虫复合为害系统，进行了害虫对棉花桃数、铃重、烂桃、僵瓣、皮棉绒长及品级、总产量和产值影响的逐步回归分析，分别建立了各复合为害系统害虫与棉花产量结构要素、品质要素、产量及产值的最优线性回归模型。定量地描述了多虫复合为害系统中害虫对棉花产量和产值的为害损失，初步探讨了多虫复合为害规律，明确了复合为害系统中各类害虫对棉花产量、品质和产值的影响途径。
According to the results of three years of field experiments, the pest was tested on three different combinations of six cotton insect pests such as peach number, boll weight, rotten peach, stiff petal, cashmere length and grade, Yield and output value of the impact of the gradual regression analysis, respectively, established a complex damage system of pests and cotton yield structure elements, quality factors, output and output value of the optimal linear regression model. Quantitative description of the pests in the multi-pest complex damage system of pests on the yield and output value of cotton damage, preliminarily discussed the rule of multi-pest compound damage, clear pests in the compound damage system on cotton yield, quality and output value ways.
