摘  要:
采用玻片浸渍法,对狼毒,苦参和百部根丙酮提取物对二点叶螨的生物活性进行了测定。3种植物提取物对二点叶螨都有较高的生物活性,狼毒,苦参和百部根提取物48 h的LC50分别为8.47mg/mL,0.62 mg/mL和1.51 mg/mL,对于二点叶螨,苦参提取物的活性最强,百部提取物的次之,狼毒提取物的最弱。

摘  要:
By means of the slide-dip method recommended by FAO,the bioactivities of extractions from roots of Stellera chamaejasme,Sophpra flavescensait and Stemana japonica with acetone to Tetranychus urticaewere tested.The results indicated that 3 plant extracts showed higher bioactivities to Tetranychus urticae.The LC_(50)of extractions of Stellera chamaejasme,Sophpra flavescensait and Stemana japonica were 8.47(mg/mL),0.62 mg/mL and 1.51 mg/mL respectively.The extraction of Sophpra flavescensait possessed the strongest bioactivities to Tetranychus urticae,and followed by that of Stemana japonica and Sophpra flavescensait.
