摘要

采用浸虫法测定了48种植物的丙酮提取物对小菜蛾(Plutella xylostella L.)的杀虫活性,并研究了苍耳(Xanthium sibiricum Patrin.)不同溶剂提取物对小菜蛾和棉蚜(Aphis gossypii Glover)的触杀作用以及苍耳丙酮提取物不同溶剂萃取物对小菜蛾的触杀作用。结果表明,在供试的48种植物中,500g·L-1黄花蒿(Artemisia annua L.)、泽漆(Euphorbia helioscopia L.)、夏至草〔Lagopsis supina(Steph.ex Willd.)Ik.-Gal.ex Knorr.〕、苍耳及葎草〔Humulus scandens(Lour.)Merr.〕的丙酮提取物对小菜蛾的杀虫活性较强。在苍耳的不同溶剂提取物中,苍耳丙酮提取物的杀虫活性最强,乙醇和乙酸乙酯提取物的杀虫活性次之。另外,50g·L-1苍耳丙酮提取物的氯仿萃取物对小菜蛾的杀虫活性最强,24h和48h的校正死亡率分别为88.33%和91.67%。 

Abstract

Insecticidal activity of extracts from forty-eight plants against to Plutellaxy lostella L. was studied by dipping method. Contact toxicity activities of different solvent extracts from Xanthium sibiricum Patrin. Against to P. xylostella and Aphis gossypii Glover and different partitioned extracts of acetone extract from X. sibiricum against to P. xylostella were also researched. The results show that 500g·L- 1 acetone extracts from Artemisia annua L., Euphorbia helioscopia L., Lagopsis supine (Steph. ex Willd.) Ik.-Gal. ex Knorr., X. sibiricum and Humulus scandens(Lour.) Merr. possess better to xicity activity to P. xylostella. In different solvent extracts from X. sibiricum, the toxicity of acetone extract is the highest, that of ethyl acetate and alcohol extracts are the second. Toxicity activity of 50g·L- 1 chloroform. partitioned extract of acetone extract from X. sibiricum against to P. xylostellais the highest, and the adjusted mortalities for 24h and 48h are 88.33% and 91.67% respectively.
