摘　　要：采用枫杨的新鲜根皮、茎皮和叶的水浸液处理钉螺，并用五氯酚钠溶液处理和清水饲养钉螺实验作对照．结果表明，５％以上的枫杨各部水浸液对钉螺具有２０％～１００％的毒杀致死作用．处理时间在２４０ｈ左右时，其死螺率可达９３．５％～１００％，含２．５％的新鲜枫杨叶和２．５％的新鲜乌桕叶、池杉叶、樟叶、羊蹄全株、青蒿全株等的混浸液，处理钉螺２４０ｈ亦分别具有９６．７％、９３．３％、８０％、１００％、８６．With pentachlorophenol sodium and pure water as controls, the soaking liquids of the fresh roots, stem barks, and leaves of Pterocarya stenoptera were used to examine their killing effect on Oncomelania hupensis . The result shows that the soaking liquid at>5% concentrations could kill 20～100% bodies of Oncomelania hupensis . When treated for 240h., the mortality of O.hupensis was up to 93.5～100%. The soaking liquid of 2.5% fresh leaves of P.stenoptera mixed with 2.5% leaves of Sapium sebiferum, Taxodium ascendens or Cinnamomum camphora, or with the whole boby of Rumex japonicus or Artemisia apiacea , killed 96.7%, 93.3%, 80%, 100%, 86.7% bodies of O.hupensis , respectively, when O.hupensis was treated for 240h.
