球形小泡螺(Bulinus globosus)采自尼日利亚伊巴丹大学植物园内的水池,根据壳高分为3个螺龄组:0～48小时壳高0.65mm,2～4周壳高2.5～5.0mm,9～12周壳高9～12mm。含羞草科(Mimosaceae)的Tetrapleuratetraptera的茎皮的甲醇提取液经真空浓缩干燥,再以蒸馏水溶解稀释提取物配成所需的浓度。比较了Aridan对不同龄期螺及卵的毒性以及影响杀螺作用的理、化因素。同时进行了氯硝柳胺和硫酸铜的平行试验。还进行了Aridan对小白鼠和池塘环境中的动植物毒性试验。三组小白鼠分别每天喂以10、100、1000mg/L的药液3个月。在一个死水塘里喷洒2,000ml甲醇浸出液,使
Bulinus globosus was collected from a pond in the Botanical Garden of Ibadan University in Nigeria and divided into three groups according to the shell height: 0.65mm in 0-48h, 2.5-5.0mm in height in 2 ~ 4 weeks , 9 ~ 12 weeks shell height 9 ~ 12mm. The methanol extract of the bark of Tetrapleuratetraptera of the Mimosaceae was concentrated in vacuo and dried. The diluted extract was dissolved in distilled water to give the desired concentration. The effects of Aridan on the toxicity of spirulina and eggs at different stages and the effect of controlling molitrix were also compared. At the same time, niclosamide and copper sulfate were tested in parallel. Aridan also conducted animal and plant toxicity tests in mice and pond environments. Three groups of mice were fed with 10,100,1000 mg / L of liquid for 3 months. Spray 2,000 ml of methanol leachate in a dead pond
