%X To reveal the mechanism and the effect of A risaema erubescens Schott against Oncomlania hupensis, the experiments were conducted in greenhouse by killing O. hupensis with the water extracts of A. erubescens. The physiological indices of liver after treatments with the water extract of tubers were also detected in this experiment. It was found that the water extracts of A. erubescens could kill O. hupensis effectively, especially, that of tubers. Mortality of O. hupensis was 88.4% after treatment with 0.1% water extract of tuber for 3d and 100% for 5d. The order of the plant parts against 0. hupensis: tuber> leaf>stem. MDA content and the activities of POD and SOD of liver treated with the water extracts of A. erubescens tuber were detected. It was found that MDA contents were 225.8% and 306.9% of controls after treating with 0.1% and 1% of water extracts of tubers for 24h, respectively. The MDA content of liver after treatment with 0.1% water extract of tubers for 48h was 129.6% of that after treatment for 24h. The activities of POD and SOD in the treated liver were significantly decreased except that in 0.1% treatment for 24h. The results in the study indicated that the water extracts of the total A. erubescens could kill 0. hupensis effectively, especially, that of tubers. An oxidative damage and a significant decrease of antioxidant capacity of 0. hupensis liver were caused by the water extracts of tubers, which might play an important role in decreasing the detoxification capacity of liver and finally, leading to the death of 0. hupensis.
