摘  要:
以藏川杨为对象,研究了室内藏川杨饲养柳蓝叶甲的产卵量,以及取食藏川杨后柳蓝叶甲体内超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性的变化。结果表明:室内藏川杨饲养柳蓝叶甲的产卵量较取食中林46产卵量低,幼虫阶段的存活率与在中林46叶片上进行的饲养有一定的差异。柳蓝叶甲取食藏川杨后,SOD和CAT活性表现出前期降低,随后升高,最后又下降的趋势,而POD活性则表现出前期升高,随后维持在较低的水平;取食藏川杨后,POD和CAT活性虽在变化趋势与取食中林46的相似,但除3龄幼虫POD高于取食中林46的以外,其它均低。

摘  要:
Taking Populus szechuanica as object,the fecundity of Populus szechuanica indoor feeding Plagiodera versicolora was studied,and the changes of SOD,POD,CAT activities in Plagiodera versicoloraafter eating two poplars were studied.The results showed that fecundity of Populus szechuanica indoor feeding was lower than that on fast growing poplar Zhonglin-46,there were some differences on survival of Plagiodera versicolora that in feeding with Populus szechuanicaand fast growing poplar Zhonglin-46.After eating Populus szechuanica,the activities of SOD and CAT decreased first,then increased,and decreased at last,but POD increased at first and then maintained at a lower level;except POD on third instar larvae was higher than feeding by Zhonglin-46,others were lower.
