| 摘 要： | 研究了赤拟谷盗Tribolium castaneurn（Herbst）不同虫态（3-4龄幼虫、1-2龄蛹和羽化1天成虫）体内过氧化物酶（POD）、过氧化氢酶（CAT）、超氧歧化酶（SOD）活力在电子束辐照条件下的变化。结果表明,赤拟谷盗不同虫态的POD活力：羽化1 d成虫〉1-2龄蛹〉3-4龄幼虫;CAT活力：羽化1 d成虫〉1-2龄蛹〉3-4龄幼虫;SOD活力：3-4龄幼虫〉1-2龄蛹〉羽化1 d成虫。辐照处理后,保护酶活力随辐照剂量的增加呈先上升后下降的趋势,赤拟谷盗3种虫态POD活力均在500 Gy辐照剂量最高;3-4龄幼虫和1-2龄蛹CAT活力在420 Gy辐照剂量最高,羽化1 d成虫300 Gy最高;3-4龄幼虫和1-2龄蛹SOD活力在420 Gy辐照剂量最高,羽化1 d成虫500 Gy最高。本试验结果有助于阐明电子束辐照对储粮害虫的生理生化效应。 |

| Abstract: | By electron beam irradiation,enzyme activity changes of peroxidase(POD),catalase(CAT),superoxide dismutase(SOD) of Tribolium castaneurn(Herbst) in different insects states(3-4th instar larvae,pupae age 1 day to 2 days and adult for 1 day eclosion) have been investigated.The results showed that POD activity of Tribolium castaneum in different states was in order: adult > pupa> larvae;CAT activity: adult > pupa> larvae;SOD activity: larvae > pupa > adult.After irradiation,the protection enzyme activity rose f... |
