| 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. |
