中文摘要：本研究旨在探讨酸模乙醇提取物对3种常见害虫(绿豆象、米象、小菜蛾)的杀虫活性，以期为后续研究酸模的杀虫机制提供理论基础。实验采用不同浓度的酸模粗提物为测试药液，利用驱避法和拒食法对3种害虫进行实验。结果表明:酸模粗提物对绿豆象和米象的最佳驱避浓度分别为30 mg/mL和50mg/mL;对小菜蛾2龄幼虫，30～80 mg/mL的浓度具有显著的拒食效果，拒食率可达到84％以上。因此，酸模粗提物有望作为一种有效的害虫驱避剂和拒食剂，值得进一步深入研究。

外文标题：Study on Biological Activity of Ethanol Crude Extract of Rumex acetosa L.Against Three Pests

外文摘要：The aim of the experiment was to investigate the insecticidal activity of ethanol extract of Rumex acetosa L.against three common pests(Callosobruchus chinensis,Sitophilus oryzae,Plutella xylostella),in order to provide a theoretical basis for the subsequent study of the mechanism of R.acetosa insecticidal.The crude extract of R.acetosa with different concentrations was used as the test liquid,and the three pests were tested by repellent and antifeedant methods,respectively.The results showed that the best repellent concentrations of R.acetosa crude extract against C.chinensis and S.oryzae were 30 mg/mL and 50 mg/mL,respectively.For the 2nd instars of P.xylostella,the concentration of 30 mg/mL to 80 mg/mL had a remarkable anti-feeding effect,and the anti-feeding rate could reach more than 84％.Therefore,the crude extract of R.acetosa is expected to be an effective pest repellent and antifeedant,which is worthy of further study.
