目的 :了解溴鼠灵对褐家鼠和杀它仗对黄胸鼠的毒杀效果。方法 :实验室用溴鼠灵对褐家鼠进行有选择性和无选择性试验。现场用杀它仗对黄胸鼠进行毒杀试验。结果 :褐家鼠对 0 .0 0 2 5 %、 0 .0 0 5 %溴鼠灵小麦和稻谷毒饵的摄食系数均大于 0 .75 ;0 .0 0 2 5 %～ 0 .0 0 5 %溴鼠灵小麦和稻谷毒饵 1～ 2次给药 ,毒杀率均大于 80 %。0 .0 0 5 %杀它仗蜡饵现场毒杀黄胸鼠 ,灭效为 90 .38%。结论 :溴鼠灵对褐家鼠的适口性良好 ,毒杀率高 ,可进行现场应用。杀它仗蜡饵在有效控制鼠类食物来源的前提下 ,盗食率较高 ,灭鼠效果较好。但因其价格高 ,各地应根据具体情况选择应用。
Objective: To understand the poisoning effect of Brodifac to Rattus norvegicus and to kill its battle on Rattus flavipectus. Methods: Rattus norvegicus was selectively and non-selectively tested in laboratory. Kill the battlefield on the scene to kill poisonous thorax test. Results: The feeding coefficients of Rattus norvegicus to 0,025,25%, 0,050% brodifacine and rice bait were all greater than 0,75% and 0,025,200% Bromhidium wheat and rice bait administered 1 to 2 times, the poisoning rate was greater than 80%. 0 .0 0 5% kill the battle wax bait live poisoned yellow rat, 90.88% off. Conclusion: Brodifacoum has good palatability to Rattus norvegicus and high toxicity rate, which can be applied on site. Kill its battle wax bait In the premise of effective control of rodent food sources, the higher rate of stealing food, rodent control effect is better. However, due to its high price, all localities should choose and apply according to the specific circumstances.
