摘　　要：将 3种药用植物材料分别粉碎后与淀粉、明胶配合制成直径 2～ 3mm的植物颗粒剂用于灭钉螺试验 ,结果表明 ,钉螺取食 3种颗粒剂后 ,2 4h死亡率分别达到 92 5 %～ 10 0 % .其毒杀效果明显优于相同植物的其它灭螺方法 ,对钉螺的致死时间比氯硝柳胺化学灭螺剂 (1× 10 -3g·L-1)提前 12～ 2 4h .用 3种植物颗粒灭螺剂进行野外灭螺实验 ,钉螺死亡率最高可达 6 1 5 % .Plant granules (2～3mm) made of starch,gelatin and medicine plant powder were used to kill Oncomelania hupensis. The results showed that after eating the plant granules,the mortality of the snail was 92.5%～100% within 24hrs.The poison effect of the plant granules was much better than that of others,e.g.,they could kill snails 12～24h earlier than Niclosamidum (1×10 -3 g·L -1 ).In a field experiment,the snail mortality was up to 61\^5% by using plant granules.
