- 摘要:
- 利用索氏提取法用乙醇水加热提取番匣茎叶的有效成分，并对提取物对槐蚜的杀虫活性进行了测定。结果表明：室内叶片法生测试验提取物对槐蚜毒效的LC50为11.8323 mg/mL，田间防治效果测定试验浓度为30 mg/mL时，对槐蚜的防治效果为94.66%。因此，番茄茎叶提取物对槐蚜有很好的杀虫效果。
- 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.
