摘  要:
主要对草乌、辣椒提取物对不同试虫的生物活性进行了初步研究。结果表明,草乌根提取物表现出较好的触杀活性,1g·mL-1草乌根提取物对麦二叉蚜和天幕毛虫的校正死亡率分别为78.51%和70.32%。辣椒果实提取物表现出较好的拒食活性,0.0625g·mL-1辣椒果实提取物对小菜蛾的拒食率为94.78%。

摘  要:
The bioactivity of two plant extracts, Aconitum kusnezoffii Reichb. and Capsicum annuum var. annuum was chiefly studied. Aconitum kusnezoffii Reichb. root extract showed favourable contacting insecticidal activity. The adjusted value of mortality rate of 1 g﹒mL-1 Aconitum kusnezoffii Reichb. extract against two pests, Schizaphis graminum (Rondani) and Malacosoma neustria testacea Motschulsky, was 78.51% and 70.32%. Red pepper fruit extract showed favourable antifeedant activity. The antifeedant rate of 0.0625 g﹒mL-1 Capsicum annuum var. annuum extract against Plutella xylostella (L.) was 94.78%.
