辣蓼草提取物对玉米蚜的拒食活性
Antifeedant Activity of Polygonumhy dropiper Extract on Corn Leaf Aphid
摘要
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 Polygon um 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,tem-perature 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 vegeta -ble insecticide with Polygonum hydropiper as raw material.关键词
