| Abstract: | The extract from leaves of Juglans mandshurica is extracted by common method.The results showed that the extract from leaves of Juglans mandshurica has insecticidal activities in contact toxicity and stomach poisoning action for Lymantria dispar.The corrected mortality is more than 50% when the concentration of the extract was above 5g/L and the insecticidal time was above 3d for all.The insecticidal activities in contact toxicity and stomach poisoning action of alcohol extract are better than chloroform extract and ethyl acetate extract. |
