摘　　要：旨在探索番茄茎叶提取物对萝卜蚜的杀虫效果。通过不同溶剂提取物杀虫试验、番茄茎叶乙醇提取物室内浓度梯度生测试验、田间小区杀虫效果试验、提取物不同溶剂萃取杀虫试验、不同浓度乙酸乙酯的杀虫试验。结果显示,提取溶剂采用乙醇提取、提取物的室内生测半致死浓度为10.5 mg/m L、高浓度的提取物田间杀虫效果较为理想、萃取溶剂为乙酸乙酯、乙酸乙酯室内生测的半致死浓度为6.51 mg/m L。Insecticidal Test of the extracts from tomato stems and leaves to Lipaphis erysimi Kaltenbach were explored in this paper. Through the insecticidal test of the extracts by using different solvent, the biological detection of indoor concentration gradient of ethanol extracts from tomato stems and leaves, the insecticidal effect test in field plot, the insecticidal test by using different concentration of ethyl acetate, the result showed the extraction solvent was ethanol, half lethal concentration of indoor biological detection was 10.5 mg/mL, the insecticidal effect by using high concentration of extracts in field plot was ideal, the solvent extraction was ethyl acetate. The half lethal concentration of indoor biological detection of ethyl acetate was 6.51 mg/mL.
