| 摘 要： | 棉铃虫Helicoverpa armigera和绿盲蝽Apolygus lucorum是两种重要的经济作物害虫。为寻找一种安全高效的防治新手段，本文对10种中草药提取物触杀活性开展了研究。结果表明，在10种中草药提取物中，苦杏仁杀虫活性最高，药后7 d棉铃虫、绿盲蝽校正死亡率分别为65.4%和100%。发现苦杏仁粗提物经不同溶剂萃取后发现，氯仿萃取时析出物对绿盲蝽触杀活性最高，药后7 d校正死亡率可达96.9%。硅胶柱分离结果表明，流分L36-48具有较高的触杀活性，药后7 d校正死亡率为84.7%。本研究评价了10种中草药提取物对棉铃虫和绿盲蝽的触杀活性，并对苦杏仁有效成分开展了初步的分离鉴定，以期为两种害虫高效安全的新型药剂开发提供理论基础。

| Abstract: | Helicoverpa armigera and Apolygus lucorum are two important pests on economic crops. In order to find safe and efficient methods to control these pests, the contact activity of the extracts from ten Chinese herbal medicines was studied. The results showed that the insecticidal activity of bitter apricot kernel was the highest among the ten herbal extracts, and the adjusted mortalities of H. armigera and A.lucorum were 65.4% and 100% after 7 d, respectively. The bioassay results of the extract of bitter apricot kernel by systematic solvent extraction showed that the activity of the precipitates in chloroform extraction against A.lucorum was the highest, with an adjusted mortality of 96.9% at day 7 after treatment. The results of column chromatography showed that the fraction L36-48 had the highest contact activity with an adjusted mortality of 84.7% at day 7 after treatment. In this study, the contact activity of the extracts from ten Chinese herbal medicines was evaluated against H. armigera and A. lucorum, and the effective components of bitter apricot kernel were preliminarily isolated and identified. This study provides a theoretical basis for the development of new efficient and safe pesticides for control of the two insect pests. |
