摘要:

用保护酶活性测试盒测定了鞭角华扁叶蜂幼虫期及预蛹滞育期间机体内保护酶系统的活力。结果表明,幼虫体内SOD和CAT活力与虫龄呈正相关,POD活力与虫龄呈负相关。同幼虫期比较,滞育预蛹体内3种保护酶的活力均有较大幅度的下降,其中SOD和CAT活力的变化表现出与气温变化的相关性,而POD活力受气温的影响较大。雄性预蛹体内3种保护酶的活力显著高于雌性,但总的代谢趋势相一致。

Abstract:

The activities of enzymes of protective system of the larvae and diapausing prepupa of sawfly Chinolyda flagellicornis were determined by the testing boxes of protective enzymes.The results showed that there was a positive correlation between the activities of protective enzyme SOD,CAT and the instars,while that there was a negative correlation between POD activities and the instars. Compared with the larva,the activities of the three protective enzymes reduced sharply in the diapausing prepupa. The activities of POD,SOD and CAT were closely correlated with the temperature. The activities of all three protective enzymes in male were obviously higher than that in the female prepupa, but there was no difference in the dynamics of them.
