研究复方中药提取物对蚜虫的杀灭效果，结果表明；5个浓度梯度的样品溶液对蚜虫均有明显的触杀作用．且死亡率随浓度增高而显著增加，即使在低浓度31．3mg/mL时，对蚜虫仍有一定的触杀作用，在24、48h后死亡率分别达40．00％、51．25％。
研究複方中藥提取物對蚜蟲的殺滅效果，結果錶明；5箇濃度梯度的樣品溶液對蚜蟲均有明顯的觸殺作用．且死亡率隨濃度增高而顯著增加，即使在低濃度31．3mg/mL時，對蚜蟲仍有一定的觸殺作用，在24、48h後死亡率分彆達40．00％、51．25％。

The research on the kill action of the compound Chinese herb extracts for aphids was made.The results showed that all of the five concentration gradients of the sample solution had apparent effects of killing aphids,and mortality increased significantly with increasing concentration. Even at low concentration of 31.3 mg/mL, there still had contact toxicity for aphids, mortality rate achieved 40.00%, 51.25% after 24,48 hours, respectively.
