[目的]在前期研究基础上,系统评价羽裂蟹甲草Cacalia tangutica的杀虫活性.[方法]采用触杀、胃毒和点滴等方法测定了羽裂蟹甲草中9种化学成分对家蝇Musca domestica、致倦库蚊Culex pipiens quinquefasciatus、菜粉蝶Pieris rapae、亚洲玉米螟Ostrinia furnacalis、红火蚁Solenopsis invicta的生物活性.[结果和结论]无羁萜对家蝇3龄幼虫的触杀活性明显,1μg/头点滴处理后48 h,校正死亡率达到86.18%,与鱼藤酮(85.67%)无显著差异.无羁萜和山奈酚对致倦库蚊4龄幼虫的毒杀活性与鱼藤酮不显著,处理后72 h,校正死亡率均超过80%.此外,无羁萜对菜粉蝶3龄幼虫、亚洲玉米螟4龄幼虫、红火蚁表现出了一定的触杀活性,无羁萜、槲皮素和山奈酚对红火蚁还具有较明显的胃毒活性.结果表明无羁萜、槲皮素、山奈酚是羽裂蟹甲草中的活性成分.

[Objective] To assess the insecticidal activities of Cacalia tangutica based on previous resear-ches.[Method] The activities of several compounds from Cacalia tangutica against Musca domestica, Culex pipiens quinquefasciatus, Pieris rapae, Ostrinia furnacalis, Solenopsis invicta were bioassayed by contact , stomach poison and drop treatment .[Result and conclusion] The results indicated that friedelin possessed a strong contact toxicity against third-instar larvae of M.domestica, and the corrected mortality was 86.18%after treatment for 48 h with 1 μg each larva by topical application , which was not signifi-cantly different from that of rotenone ( 85.67%) .Friedelin, kaempferol and rotenone were equitoxic to fourth-instar larvae of C.pipiens quinquefasciatus.The corrected mortalities after treatment for 72 h were more than 80%.Moreover, friedelin had some degree of contact toxicities against third-instar larvae of P.rapae, fourth-instar larvae of O.furnacalis and S.invicta.Friedelin, quercetin and kaempferol had obvious stomach poison activities to S.invicta.Generally friedelin , quercetin and kaempferol are the ac-tive ingredients of C.tangutica.
