Abstract: 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.

Key words: Extracts from tomato stems and leaves, Pest control, Biological detection, Botanical pesticide
