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％。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.
