[目的 ]评价进口杀它仗蜡块毒饵在大面积灭鼠中的应用价值。 [方法 ]用国产溴敌隆大米毒饵作为对照 ,褐家鼠为实验动物 ,实验室有选择性摄食法、无选择性摄食法和现场盗食试验测定两种毒饵的适口性、室内灭效和现场盗食率。 [结果 ]杀它仗蜡块和溴敌隆米饵的摄食系数分别为 0 .0 2 %和 0 .76 ;多剂量有选择性室内灭效杀它仗和溴敌隆分别为 30 %和 10 0 % ;单剂量无选择性室内灭效杀它仗明显高于溴敌隆 ;现场盗食率溴敌隆米饵高于杀它仗蜡块。[结论 ]进口杀它仗蜡块在城乡大面积灭鼠中的实际应用价值低于国产溴敌隆大米毒饵。
[Objective] To evaluate the application value of imported bait for killing wax paraffin in a large area of rodent control. [Method] The domestic brood eneral rice bait was used as a control. The Rattus norvegicus was used as the experimental animal. The selective feeding method, selective feeding method and on-site theft test were used to determine the palatability, Live stealing food rate. [Result] The food intake coefficients of killing wax tablets and brood-rifamil were 0. 02% and 0. 76 respectively. The multi-dose selective indoor-use kill-off and bromadiolone were 30% and 10% 0%; single-dose non-selective indoor kill kill their battles was significantly higher than bromadiolone; spot rate of brood-poison broodstock bait higher than kill its battle wax block. [Conclusion] The practical application value of imported paraquat wax blocks in the large-scale deratization of urban and rural areas is lower than that of homemade bromadiolone rice bait.
