摘　　要：以款冬蚜虫为试验对象,采用浸虫法,研究了12种植物提取物对款冬蚜虫的触杀活性。结果表明:12种植物提取液在10mg/mL浓度下对款冬蚜虫均有一定的触杀作用,其中狼毒大戟、鸢尾、粗茎鳞毛蕨3种植物提取物对款冬蚜虫48h的触杀活性达80%左右,狼毒大戟提取物的毒力最强,24h的致死中浓度(LC50)为9.025mg/mL,鸢尾、粗茎鳞毛蕨24h的致死中浓度(LC50)分别为16.111、33.612mg/mL。狼毒大戟、鸢尾、粗茎鳞毛蕨具有研究开发的价值。Taking coltsfoot aphids as research object,using insect-soaking method,the insecticidal activities of the crude extracts of 12 plants were tested against coltsfoot aphids.The results showed that at concentration of 10mg/mL,alcohol extracts from 12 plants had a certain insecticidal activity on coltsfoot aphid.Insecticidal activity of extract fromEuphorbia fischeriana,Iris tectorum,Dryopteris crassirhizoma were stronger than others,their corrected mortality reached about80%after 48 hours.The toxicity of extracts from E.fischeriana was the strongest,which LC50 on the aphid was9.025mg/mL after 24 hours,and LC50 of the extracts of I.tectorum,D.crassirhizoma were 16.111 mg/mL,33.612mg/mL respectively after 24 hours.E.fischeriana,I.tectorum and D.crassirhizoma had excellent value for further research and development.
