为明确无患子皂苷对甜菜夜蛾的控制作用,本试验分别用添加无患子皂苷(0.25、0.5、1、2、4、8、16 mg/g)的混毒饲料喂养甜菜夜蛾2龄幼虫,测定甜菜夜蛾幼虫存活率、幼虫发育历期、蛹重、化蛹率、卵孵化率、性比等指标...展开更多 为明确无患子皂苷对甜菜夜蛾的控制作用,本试验分别用添加无患子皂苷(0.25、0.5、1、2、4、8、16 mg/g)的混毒饲料喂养甜菜夜蛾2龄幼虫,测定甜菜夜蛾幼虫存活率、幼虫发育历期、蛹重、化蛹率、卵孵化率、性比等指标。采用液相色谱-质谱联用仪(HPLC-MS)分析无患子皂苷中的主要化学成分。结果表明,喂饲后72 h,取食4 mg/g混皂苷饲料的甜菜夜蛾幼虫开始死亡,其幼虫存活率随皂...

In order to clarify the control effect of Sapindus saponin on Spodoptera exigua,the 2nd instar larvae of S.exigua were fed with the feed mixed with seven different concentrations(0.25,0.5,1,2,4,8 and 16 mg/g)of Sapindus saponin.The larval survival rate,larval developmen...MORE In order to clarify the control effect of Sapindus saponin on Spodoptera exigua,the 2nd instar larvae of S.exigua were fed with the feed mixed with seven different concentrations(0.25,0.5,1,2,4,8 and 16 mg/g)of Sapindus saponin.The larval survival rate,larval developmental duration,pupal weight,pupation rate,egg hatching...
