Abstract:
The effective component of leaves and stems of Solanum lycopersicum were extracted with alcohol-water solution by soxhlet method accompanied by heating to boiling,and the insecticidal activities of extracts were detected against Aphis sophoricola Zhang.The results showed that the extracts of indoor leaf bioassay were toxic to Aphis sophoricola Zhang with LC50 of 11.8323 mg/mL.The results of the control efficiency determination experiment in the field indicated that the control efficiency of the extracts was 94.66% against the insect when the concentration of extracts was 30 mg/mL.Therefore,the extracts from leaves and stems of Solanum lycopersicum had a fine insecticidal activity against Aphis sophoricola Zhang.
