Abstract
Abstract Biological activity of an extract of the root of Stellera chameajasme with ethanol by dip (SCEE) against 5 insect pests, Pieris rapae, Plutella xylostella, Spodoptera litura, Myzus persicae , and Ostrina fumalis as tested. The LD, of stomach poison of SCEE against the fifth instar larvae of P. rapae was 12. 32 μarvae day 2 after treatment. With SCEE at concentration of 5, 2. 5 and 50 mg/mL, the fifth instar larvae of P. rapae , the third instar larvae of P. xylostella , and the third instar larvae of S. litura by disc leaf dipped method, had corrected mortalities of 100%, 31. 03 % and 16. 67 % 7 days after treatment respectively. The LC 50 of SCEE against M. persicae was 0. 599 2 mg/mL after day 2 treatment by leaf dipped method. With SCEE at 10 mg/mL for the third instar larvae of O. furnucalis by mixture pesticide method, the corrected mortalities of 65. 52% and 85. 72% days 7 and day 14 after treatments respectively. The results showed that SCEE possessed strong biological activity to P. rapae, O. furnacalis , and M. persicae , while possessed weak biological activity to S. litura and P. xylostella .
