Comparison of Hydrogen Peroxide,Antioxidant Enzymes and Hormones between Diapause and Non-diapause Prepupae of Cotesia vestalis
摘要
Abstract
In order to investigate the effects of hydrogen peroxide and hormones on diapause in Cotesia vestalis,hydrogen peroxide content,activities of three antioxidant enzymes（superoxide dismutase（SOD）,peroxidase（POD）,and catalase（CAT））,and contents of 20E and JH Ⅲ between diapause and non-diapause prepupae were compared.Results showed that the hydrogen peroxide content,SOD and POD activities and 20E content in diapause prepupae were significantly lower,while the CAT activity and JH Ⅲ content were significantly higher,when compared to those in non-diapause prepupae.We speculated that high concentrations of JH Ⅲ inhibited the synthesis and release of 20E,the latter reduced hydrogen peroxide content by decreasing SOD activity and increasing CAT activity,and finally caused prepupae of C.vestalis to enter diapause.关键词
