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.

Key words: Chinolyda flagellicornis, Activities of protective enzymes, Diapause
