[目的]基于均匀设计法探讨黄花乌头、北乌头和高山乌头的水蒸气蒸馏液对大螟、玉米螟和大豆荚螟的触杀作用。[结果]对大螟的24 h触杀结果表明:3种乌头对大螟均有较强触杀作用,触杀活性顺序为北乌头>黄花乌头>高山乌头。48 h时黄花乌头和北乌头对大螟保持着较好的触杀作用,触杀活性顺序为北乌头>黄花乌头。72 h仅北乌头还保持着较强的触杀作用。24、48、72 h致死中浓度LC50值分别为12.72、5.43、1.44 mg/L,校正死亡率分别达85.7%、88.9%、98.2%;对玉米螟的24、48 h触杀结果表明:北乌头和高山乌头对玉米螟均有较强的触杀作用,触杀活性顺序为北乌头>高山乌头。72 h仅北乌头保持着较强的触杀作用。24、48、72 h致死中浓度LC50值分别为15.97、15.17、1.71 mg/L,校正死亡率分别达92.3%、95.0%、99.4%;对大豆荚螟的24、48、72 h触杀结果表明:北乌头和高山乌头对大豆荚螟均有较强的触杀作用,触杀活性顺序均为北乌头>高山乌头。其24、48、72 h致死中浓度LC50值分别为17.27、17.18、12.39 mg/L,校正死亡率分别达90.0%、91.8%、99.0%。[结论]3种乌头对大螟均有较强触杀作用,北乌头和高山乌头对玉米螟和大豆荚螟表现出较强的触杀效果,黄花乌头对玉米螟和大豆荚螟的触杀效果不显著。
[Objective] The research aimed to discuss the contact action of steam distillation liquid of Aconitum corolla, North aconite and Alpine aconite to Sesamia inferens, Ostrinia furnacalis and Soybean pod borer, based on the uniform design method. [Result] The result of 24 h contact with Sesamia inferers showed that all the three kinds of Aconitum showed stronger contact with Sesamia inferens. The order of contact activity was North Aconitum> Aconite> Aconitum acutum. 48 h when Aconitum and Aconite on the Stem borer to maintain a good contact action, contact activity order North Aconitum> Aconite. 72h North Aconit also maintained a strong contact effect. The lethal LC50 values of 24, 48 and 72 h were respectively 12.72, 5.43 and 1.44 mg / L, and the corrected mortality rates were 85.7%, 88.9% and 98.2% respectively. The results of 24 h and 48 h contact with corn borer showed that: Head and alpine Aconitum have a strong contact effect on the corn borer, contact activity order North Aconitum> alpine Aconitum. 72 h North aconite maintains a strong contact effect. The LC50 values of lethal concentration at 24, 48 and 72 h were 15.97, 15.17 and 1.71 mg / L respectively, and the corrected mortality rates were 92.3%, 95.0% and 99.4% respectively. North Aconitum and Aconitum acutum had stronger contact effects on Soybean pod borer, and the order of contact activity was North aconite> alpine aconite. The LC50 values of 24, 48 and 72 h lethal concentrations were 17.27, 17.18 and 12.39 mg / L, respectively. The corrected mortality rates were 90.0%, 91.8% and 99.0% respectively. [Conclusion] The three kinds of aconites had strong contact and killing effects on Sesamia inferens. The aconite and aconite aconite showed strong contact effects on the maize borer and Soybean pod borer, Touch effect is not significant.
