瑞香狼毒根提取物对四种蔬菜害虫的生物活性
Bioactivity of Extraction of Stellera chameajasme on Four Vegetable Pest Insects
【摘要】 应用叶碟法就瑞香狼毒 (StellerachameajasmeL .)根乙醇提取物 (简称SCEE)对4种重要蔬菜害虫的拒食率、LC50 和处理后 7d的校正死亡率进行了测定。结果表明 ,SCEE对菜粉蝶、桃蚜的生物活性很强 ,对斜纹夜蛾和小菜蛾的生物活性较弱
【Abstract】 Bioactivity of SCEE (extraction of root of Stellera chameajasme with ethanol by dip) such as LC 50 (lethal concentration causing 50% mortality), antifeedant rate and corrected mortality within 7 days after treatment of SCEE to larvae were tested with leaf discs. The results showed that SCEE possessed strong bioactivity on Myzus persicae and Pieris rapae,while SCEE possessed weak bioactivity to Plutella xylostella and Spodoptera litura.
