摘　　要：[目的]明确白粉病和斑叶蝉共同危害对葡萄叶片生理生化特性的影响,为病虫害防治提供参考。[方法]以哈密地区无核白葡萄品种为试验材料,研究感染白粉病后不同斑叶蝉种群对葡萄生理指标变化的影响。[结果]当感染白粉病后随虫口密度增加,叶绿素含量减少,过氧化物酶(POD)和超氧化物歧化酶(SOD)活性也随之增加,丙二醛(MDA)和可溶性蛋白含量变化复杂。[结论]感染白粉病后,斑叶蝉危害给葡萄造成损伤,葡萄自身也进行了一系列复杂的适应防御反应。[Objective] Effects of powdery mildew and Erythroneura apicalis on physiological and biochemical characteristics of Vitis vinifera to provide reference for controlling pest and diseases. [Method]Effects of different populations of Erythroneura apicalis on physiological and biochemical characteristics of Vitis vinifera infected by powdery mildew were studied by taking the varieties of Thompson seedless in Hami district as the experimental material. [Result]After Vitis vinifera was infected by powdery mildew,chlorophyll content decreased as the populations of Erythroneur aapicalis increased; POD and SOD activities rose as the populations of Erythroneur aapicalis rose; while MDA and soluble protein contents were complicated. [Conclusion] After Vitis vinifera was infected by powdery mildew,Erythroneura apicalis caused damage to Vitis vinifera,meanwhile Vitis vinifera also took a series of complex adaptive defense responses after infected by powdery mildew and Erythroneura apicalis.
