摘要: 目的用浓度分别为0.10%、0.15%、0.20%的C型肉毒毒素对大同市草地害鼠进行杀灭试验,以确定草地灭鼠应用的最佳浓度。方法试验采取随机区组排列设计,试验区设4个小区,其中一个小区为对照组,另3个小区采用不同浓度的C型肉毒毒素进行处理。结果C型肉毒毒素有很高的安全性,不伤害鼠类天敌;利用0.10%、0.15%、0.20%三个浓度的C型肉毒毒素均能有效地杀灭害鼠,各浓度间灭鼠效果差异无显著性(P>0.05)。结论利用C型肉毒毒素进行草地灭鼠可行,从经济效益及生物多样性考虑,其最佳浓度为0.15%。

Abstract: Objective To acquire the optimum concentration of Type-C botulin used in killing wild rodent on the grassland in Datong city.Methods A killing rodent test was performed with 0.10%?0.15% and 0.20% Type-C botulin respectively.Results The results showed that Type-C botulin had high safety without killing natural enemies of rodent.The several concentrations of Type-C botulin could kill rodent efficiently.There was no obvious difference among them in killing rodent(P>0.05).Conclusion In view of the economic effciency and biodiversity,we consider that Type-C botulin could be used to control rodent effectively in Datong city and the optimum killing concentration should be 0.15%.
