试验选取宁夏地区10种植物粗提物对枸杞主要害虫枸杞蚜虫(Aphis sp.)、蓟马(Tetranychus kanza-wai )、木虱若虫(Poratrioza sinica )进行杀虫活性筛选.结果表明：披针叶黄华(Thermopsis lanceolata )、乳浆大戟(Euphorbia esula)、狼毒(Stellera camaejasme)和伏毛铁棒锤(Aconitum flavum)对枸杞主要害虫具有较好的杀虫活性,经过毒力回归分析,4种植物乙醇提取物对枸杞蚜虫的LC50值分别为258.90、303.79、529.73和822.90 mg/L,尤其以披针叶黄华和乳浆大戟效果较为明显,可进一步分离纯化,提高杀虫活性.

This paper reported bioactivity screening of extracts from 10 plants in Ningxia against major pests of wolfberry,including wolfberry aphids,thrips and psyllid nymph.The results showed that four spe-cies of plants which included Thermopsis lanceolata,Euphorbia esula,Stellera camaejasme,Aconitum fla-vum possessed strong biological activities against major pests on wolfberry.The regression analysis demon-strated,the LC50 of ethanol extracts from four species of plants to wolfberry aphids were 258.90,303.79, 529.73 and 822.90 mg/L,respectively especially T.lanceolata and E.esula,which were worth to be studied deeply.
