Abstract: The paper reported the Mice LD50 determination and Rodent control field tests with Botulinum Type C.The LD50 were 0.0891±0.0473 ml/kg by 25℃ for 48h; 0.1363±0.0597 ml/kg by 30℃ for 48h;0.1712±0.0652ml/kg by 35℃ for 48h.The Botulinum Type C was powerful for rodent control.In the field tests with rice baits, the killing rate by the Botulinum Type C was 91.08%; 89.41% and 88.04%.It was showed that the Botulinum Type C fit in with the South China.
摘要: 目的:观察C型肉毒梭菌毒素对小白鼠的LD50及现场灭鼠效果。方法:毒力测定采用定量药液灌胃法;用粉迹法调查鼠密度,计算灭鼠率。结果:该药在25℃、30℃、35℃放置48小时,对小白鼠的LD50分别为0.0891±0.0473、0.1363±0.0597和0.1712±0.0652ml/kg;现场试验,昼最高气温20~25℃,夜最低气温15~18℃,3个试点村的灭鼠率分别为91.08%、89.41%、88.04%。结论:C型肉毒梭菌毒素的毒力甚强,适宜在我国南方地区推广使用。
