摘　　要：目的 :利用析因设计进行现场有选择性摄食试验 ,组合筛选灭鼠毒饵 ,以提高毒饵的接受性 ,并评价优选毒饵的灭鼠效果。方法 :将食糖、花生油、食盐和鱼粉取 2～ 3种浓度全面组合后制备成 36种 0 .0 0 5 %溴敌隆颗粒试验毒饵 ,与对照毒饵一起在现场进行有选择性摄食试验 ,运用SPLM中文统计软件处理数据 ,优选配方 ,并利用优选配方毒饵和对照毒饵进行现场灭鼠效果试验。结果 :第 13号试验毒饵为优选毒饵 ,摄食系数为 1.94,对照毒饵的摄食系数为 0 .5 4。鱼粉的添加不但降低了毒饵的接受性 ,而且与食盐间有交互作用。各诱饵间无二级交互作用。现场灭鼠试验 ,优选毒饵的灭鼠率为 97.1% ,对照毒饵为 70 .0 %。结论 :应用析因设计组合筛选灭鼠毒饵 ,方法可行 ;Objective: Factorial experiment was applied to the choice feeding test on field to screen the combinations of attractants of rodenticide baits for the most suitable bait and to evaluate the palatability of the trial poison baits and the mortality of the most suitable bait. Methods: 36 kinds of 0.005 % bromadiolone trial poison baits combined entirely by sugar, peanut oil, salt and fish meal on 2-3 levels of concentration and control poison bait were tested in the choice trial on field, in which SPLM was implemented in analysis of variance. Result: The 13th trial poison bait was the most suitable, which feeding coefficient was 1.94 , relatively that of control poison bait was 0.54 . There was interaction between salt and fish meal. On the field poisoning test, the most suitable poison bait gave 97.1 % of mortality, but control poison bait 71.6 %. Conclusion: The field trial of screening on the combinations of attractants of rodenticide baits by factorial experiment bait is feasible; the mortality of the most suitable bait is better.
