摘　　要：[目的]筛选出对棉蚜具有较好生物活性的植物。[方法]测定了8种中药材植物乙醇提取物对棉蚜的毒杀、触杀、忌避活性。[结果]在10 mg/ml的浓度下,藁本乙醇粗提物杀虫活性较好,48 h后内吸毒杀校正死亡率为70.69%,触杀校正死亡率为95.67%,忌避率为86.67%。[结论]藁本对棉蚜具有较好的生物活性,可望用于进一步研究与开发。[Objective] The aim was to screen plants which had good bioactivities to cotton aphid.[Method] Bioactivities of alcohol extracts from 8 Chinese herbs on the cotton aphid were tested.[Result] The insecticidal activity of alcohol extract from Ligusticun sinense Oliv was stronger than others at the dosage of 10 mg/ml,After 48 hours,the corrected mortality of systemic insecticidal activity was 70.69％,the corrected mortality of contact activity was 95.67％,and the calibrated evadible rate was 86.67％.[Conclusion] L.sinense had good bioactivity to cotton aphid,so it could be used to further exploration.
