茶麸原药、五水硫酸铜原药、农用碳酸氢铵对福寿螺都有一定的毒杀作用,其中茶麸原药对福寿螺的防效最佳,药后24 h,15 d螺龄的福寿螺的死亡率高达76.7%,药后48 h防效达100%;五水硫酸铜原药防效次之,药后24 h,防效达40.3%,药后48 h也表现出良好防效,达100%;而农用碳酸氢铵对低龄螺呈现出一定的防效,在药后48 h对6 d螺龄的防效达100%,但对25 d以上的高龄螺防效则较差.

In the paper, we found that tea bran technical material (TC), chalcanthite TC and agricultural ammonium bicarbonate could kill certain Ampullaria gigas, and tea bran had best control effect, with the death rate of fifteen days' A. gigas of 76.7% 24 hours after using the tea bran TC, while the death rate reached to 100% after using the pesticide 48 hours. Chalcanthite TC had better control effect, and the death rate was 40.3%24 hours after using chalcanthite TC, while the death rate reached to 100% 24 hours later. Agricultural ammonium bicarbonate could kill certain younger A. gigas, and the death rate of six days' A. gigas was 100% 48 hours after using the pesticide, but it had worse control effect on older A. gigas.
