【摘要】 应用均匀设计法研究了蝙蝠葛鲜根的不同提取液对三化螟的触杀作用。结果表明,乙醇浸提液对三化螟具有较强的触杀作用,72 h后对三化螟的致死中浓度(LC50)为7.148 3 mg·mL-1,触杀致死率为95.5%;乙酸乙酯浸提液和水蒸汽蒸馏液对三化螟的触杀作用不显著。更多还原

【Abstract】 The contacting death effects of various extractions from root of Menispermum dauricum DC.on Tryporyza incertulas was studied by the method of uniform design.The results showed that ethanol extract had high contacting activity,the 72 h LC50 of death was 7.1483 mg·mL-1,the rate of death was 95.5%.Wet distillation and ethyl acetate extracts had indistinctively contacting activity.更多还原
