摘　　要：研究了美洲黑杨不同无性系对分月扇舟蛾(Clostera anastomosis)体内消化酶和保护酶活性的影响。结果表明,大多数抗性无性系对分月扇舟蛾体内的3种消化酶活性有显著的抑制作用,而94-30、94-12、74-4等几个感性无性系的3种消化酶的活性比对照有一定的提高;分月扇舟蛾幼虫取食抗性无性系后,体内SOD和CAT酶活性相对于对照显著上升,说明这些无性系对分月扇舟蛾的SOD和CAT酶活性有显著的激活作用,而94-30、94-12、74-4等几个感性无性系对这两种酶的活性影响不大,甚至有轻微抑制作用。不同无性系对分月扇舟蛾幼虫POD酶活性的影响无显著相关性。The influences of 18 clones of Populus deltoides on the activities of digestive and protective enzymes in larva of Clostera anastomosis were studied. Results indicated that most of the resistant clones inhibited the activities of three digest enzymes in larvae of Clostera anastomosis statistically, while the three digest enzymes activity tested in No. 94-30,94-12, 74-4 clones were higher than those of controls. The activity of superoxide dismutase （SOD） and catalase （CAT） in larva of Clostera anastomosis were higher than that of control statistically after feeding with resistant clones. However, no distinct effects of No. 94-30,94-12, 74-4 clones on the activity of the two enzymes, even weak inhibition were showed. A significant relationship between peroxidase （POD） activity in larvae of Clostera anastomosis and certain clones of Populus deltoids did not exist. The results founded scientific basis for selecting new poplar strains worthy of extending in production.
