用溴敌隆进行了食品行业灭鼠试验,0.005%溴敌隆对食堂、食品加工房、食品库、副食售卖店、饲养场平均灭鼠率分别为95.69%、95.58%、95.15%、100%、93.24%,其中饼干(糕点)加工房灭鼠率98.79%,明显高于肉食加工房90.36%(x~2=8.71 P<0.01);烟酒库灭鼠率100%高于果品库88.23%,差异有极显著性意义(μ=21.47 P<0.01)。溴敌隆与敌鼠钠盐毒饵杀灭褐家鼠分别为96.09%、83.33%,差异有显著性意义(x~2=3.92 P<0.05);杀灭小家鼠为94.50%,87.56%,差异无显著性(x~2=1.2 P>0.05);杀灭黄胸鼠为92.23%,81.81%有显著性差异(x~2=4.81 P<0.05)。溴敌隆死鼠高峰在投毒后第3～5天。从解剖55只死鼠均可见典型的抗凝血杀鼠剂病变,经8个月的动态观察,以食品加工房回升率最快(10.46%),副食售卖店回升率最慢(1.91%)。作者认为溴敌隆药源充足,毒鼠力强,安全可靠,适用于城乡大面积灭鼠。
The experiment of rodent control was conducted with bromadiolone in the food industry. The average rate of rodent infestation of 0.005% bromadiolone was 95.69%, 95.58%, 95.15% and 95.15% respectively in canteens, food processing houses, food banks, , 93.24% respectively. The rate of rodent control in biscuits processing was 98.79%, which was significantly higher than that in meat processing workshops 90.36% (x ~ 2 = 8.71 P <0.01) , The difference was extremely significant (μ = 21.47 P <0.01). The ratio of bromadiolone and natriatal sodium bait to kill brown locusts was 96.09% and 83.33%, respectively, with significant difference (x ~ 2 = 3.92 P <0.05). The killing rate was 94.50% and 87.56% (X ~ 2 = 1.2 P> 0.05). There were significant differences between the two groups (x ~ 2 = 4.81 P <0.05). Bromadiolone rat peak in the poisoning after 3 to 5 days. From the dissection of 55 dead rats showed typical anticoagulant rodenticides lesions, after 8 months of dynamic observation, the fastest rate of food processing room (10.46%), the slowest recovery rate of non-staple food stores (1.91%) . The author believes that bromadiolone sufficient source, tetramine strong, safe and reliable, suitable for large-scale urban and rural anti-rat.
