对异心叶桉提取物作室内杀钉螺实验观察，发现异心叶桉树叶和树枝中含有较高的杀钉螺成分。树叶水浸液浓度5000mg／L和10000mg／L室内浸杀钉螺72h死亡率分别为60．0％和87．5％；树叶乙醇提取物25mg／L浸杀钉螺72h死亡率达100％，在25±1℃时对钉螺浸杀48h和72h的LC50分别为16．0mg／L和12．2mg／L。鱼毒试验发现该提取物对斑马鱼毒性较低。认为桉树是具有较高杀灭钉螺价值的候选植物。
The isolates of Eucalyptus extract for indoor kill snail experimental observation found that different heart leaves and branches of Eucalyptus leaves contain higher ingredients to kill snails. The mortality rates of leaf water immersion 5000mg / L and 10000mg / L indoor diphtheria 72h were 60.0% and 87.5% respectively. The mortality rate of leaf ethanol extract 25mg / L dip snail 72h was 100% The LC50 of snail for 48h and 72h at ± 1 ℃ were 16.0mg / L and 12.2mg / L, respectively. Fish poisoning test found that the extract of zebrafish toxicity is low. Eucalyptus is considered to be a candidate plant with higher value for killing snails.
