T heresults showed that the acetone extract of C. zexlanicum had . . 50 95 5. 16 / a good activity to H armigera T he LC values and the LC values were mg mL and 27.26 mg/ mL after 72 h of treatment; the corrected mortality were 69.8% and 80.2% after 48 h and 72 h of treatment at 13.33 mg/ mL concentration and the corrected mortality was 64. 0% after 72 h of treatment at 6.67 mg mL concentration T heresults also indicated that acetone extract of/ . C. z exlanicum significantly inhibited esterase, carboxylesterase, alkaline phosphate esterase and acid phosphate esterase activities of H . armigera under various acetone extract concentrations of 5. 0 , 4. 0 , 3. 0 , 2. 0 and 1. 0 g mL the higher the treatment concentration the heavier the/ ; , inhibition.
