[目的]探讨2-十三烷酮、槲皮素和单宁酸3种植物次生物质与杨扇舟蛾谷胱甘肽S-转移酶(GSTs)的关系。[方法]用0.01、0.10和1.00 mg/ml浓度的2-十三烷酮、槲皮素和单宁酸处理的杨树叶子分别饲养杨扇舟蛾幼虫,测定喂饲后72 h内杨扇舟蛾虫体GSTs的活性。[结果]低浓度的2-十三烷酮和槲皮素对杨扇舟蛾体内GSTs活性有抑制作用,且随着浓度升高,杨扇舟蛾体内GSTs活性又略有回升,具有一定的诱导作用;而单宁酸的浓度越大,杨扇舟蛾体内GSTs活性越低,不存在诱导作用。[结论]为杨扇舟蛾的有效防治提供了参考。
[Objective] The research aimed to discuss the relationship between secondary metabolites of 2-tridecanone, quercetin and tannic acid and Glutathione S-transferase (GSTs) [Method] The larvae of C. aeruginosa were fed on poplar leaves treated with 2-tridecanone, quercetin and tannic acid in concentrations of 0.01, 0.10 and 1.00 mg / ml, respectively. Activity of parasites GSTs. [Result] Low concentrations of 2-tridecanone and quercetin had inhibitory effects on the GSTs activity of B. aeruginosa, and the GSTs activity of A. noctua rose slightly with the increase of concentration, and had a certain induction effect While the concentration of tannic acid increased the activity of GSTs in C. aeruginosa was lower and there was no induction effect. [Conclusion] This provided a reference for the effective control of.
