摘要 [目的]探究不同条件下辣蓼草乙醇提取物对玉米蚜的拒食活性。[方法]采用单因素试验和正交试验，研究不同浓度、温度和时间条件下辣蓼草提取物对玉米蚜的拒食率。[结果]提取物浓度为100.00 mg/mL、温度为30 ℃、时间为48 h时辣蓼草提取物对玉米蚜的拒食活性最高。提取物浓度对辣蓼草拒食活性影响最大，其次为处理时间因素。[结论]该试验结果为开发以辣蓼草为原料的植物性杀虫剂提供了理论依据。

Abstract [Objective]The aim was to study on antifeedant activity of Polygonum hydropiper ethanol extract on corn leaf aphid under different conditions.[Method]Using single factor and orthogonal test，the antifeedant activity of Polygonum hydropiper ethanol extract on corn leaf aphid under different concentration，temperature and time was studied.[Result]The results showed that under concentration of 100.00 mg/mL，temperature 30 ℃and time 48 h，the antifeedant activity of Polygonum hydropiper ethanol extract was the highest.Extract concentration was the key factor influencing the antifeedant activity，followed by time factor.[Conclusion]The study provides theoretical basis for development of vegetable insecticide with Polygonum hydropiper as raw material.
