摘要: 本文报道辽宁省化工研究院研制的溴杀灵,对福建省常见3种家鼠的毒力和灭鼠效率。溴杀灵对褐家鼠的LD50为1.801±0.233mg/kg,对黄胸鼠的LD50为3.292±0.421mg/kg,对小家鼠的LD50为11.003±1.431mg/kg。0.01%溴杀灵大米毒饵对黄胸鼠平均摄食系数为1.75,室内灭效为100%,现场灭鼠对褐家鼠的杀灭率为89.96%。

Abstract: The toxicity and killing efficiency of Bromethallin were investigated against three species of rodents in Fujian during April to July, 1994. The results showed that the LD50 were 1.801±0.233mg/kg for Rattus norvegicus,3.292±0.421mg/kg for Rattus flavipectus and 11.003±1.431mg/kg for Mus musculus, respectively.The feeding coefficient of the rice bait ( 0.01% Bromethallin) was 1.75.Its killing ratioes appeared to be 100% against R,flavipectus in laboratory test and 89.96% against R,norvegicus in field test.
