摘　　要：对朱砂叶螨(Tetranychuscinnabarinus(Boisduval))危害后豇豆(Vignasinensis)幼苗叶片PPO、PAL和POD活性及同工酶进行了研究.结果显示:随着危害时间延长,处理叶片PPO、PAL和POD的活性与对照相比均升高,差异显著,且两处理之间也存在显著差异;POD同工酶电泳结果显示,随着危害程度的增大,除了部分同工酶谱带加强外,还诱导产生了新的同工酶谱带.Populations of carmine spider mite have been studied to determine their influence on PPO,PAL and POD isoenzymes of cowpea seedling leaves.The results are as follows:1)2～8d after treatment,the activities of PPO,PAL and POD increase remarkably(P<001)compared with control group,and there is difference(P<005)between different population groups.2)The POD isoenzymes are analyzed by using PAGE.The results show that the activities of some POD isoenzymes enhance,furthermore several new POD isoenzymes are induced with damaged days and increasing densities.
