摘要
本文研究了瑞香狼毒根部粗粉乙醇提取物对水稻害虫大螟和二化螟的毒杀活性,当浓度为2.0g/L、作用时间为72h,乙醇提取物对大螟致死率为92.4%,二化螟的死亡率为20.9%。同时还系统研究了瑞香狼毒根部粗粉其它极性溶剂提取物对大螟和二化螟的胃毒活性、杀卵活性和内吸活性,结果表明瑞香狼毒对水稻大螟和二化螟具有一定的杀灭作用。
The paper studied on the killing activity of the ethanol extracts from stellera chamaejasme roots against pests sesamia inferens and chilo suppressalis walker, when the concentration of ethanol extracts was 2.0g/L and time was 72 hours; the death rate of sesamia inferens was 92.4% and the chilo suppressalis walker was 20.9%. Also the stomach poisonous activity, killing egg activity and in-attract activity were studied, the results showed that stellera chamaejasme had killing activity against sesamia inferens and chilo suppressalis walker.
