大豆胰蛋白酶抑制剂和防御信号物质对斜纹夜蛾幼虫保护酶的影响OA北大核心CSCDCSTPCD
Effects of soybean trypsin inhibitor and defense signaling compounds on the protective enzymes in Spodoptera litura larvae
以广食性害虫斜纹夜蛾为研究对象,连续6代自二龄或三龄开始用含有大豆胰蛋白酶抑制剂(soybean trypsin inhibitor,SBTI)的人工饲料喂养幼虫,饲养至五龄时测定SBTI对幼虫保护酶的影响.结果表明,SBTI抑制斜纹夜蛾幼虫SOD、CAT活性,随着饲养代数的增加,SBTI的抑制效果降低；SBTI可显著升高斜纹夜蛾幼虫POD活性.预先接触外源植物防御信号物质茉莉酸甲酯和水杨酸甲酯48 h均可显著影响斜纹夜蛾幼虫体内保护酶SOD、P…查看全部>>
In this study, the second or third instars of euryphagous insect Spodoptera litura larvae were continuously fed with the diets containing soybean trypsin inhibitor (SBTI) for six genera-tions , and the protective enzyme activities in the midgut and fatbody of the fifth instars of S. Litu-ra larvae were evaluated. SBTI inhibited the SOD and CAT activities, but the inhibition effect decreased with the increase of successive culture generation. On the other han…查看全部>>
