毒鼠磷毒杀社鼠的浓度选择

Selection of the Bait Concentration of Gophacide for Poisonning Rattus niviventer

室内毒杀试验表明,0.1、0.3、0.5、0.7和1.0%的毒鼠磷大米毒饵对社鼠的毒杀效果均高达100%。适口性以0.1、0.3和0.5%毒饵最好,这3种浓度的毒饵摄食量显著或极显著高于0.7%和1.0%。因此,毒杀社鼠应选择0.5%以下浓度为好。

The rice baits with 0.1, 0.3, 0.5, 0.7 and 1% concentrations of gophacide were used to poison Rattus niviventer in laboratory. The results show that the effect of all these baits is very good, with the killing rate of one hundred percent. The blits with 0.1, 0.3 and 0.5% gophacide are better palatable than other baits. Therefore the best baits for poisonning the rat are those with lesser than 0.5% gophacide.
