正交试验在灭鼠毒饵诱饵组合筛选中的应用

Field Trial of Screen on Combination of Attractants of Rodenticide Baits by Orthogonal Design

目的 利用正交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 将糖精、花生油、食盐和白酒取 2～ 3种浓度选用L18(2 1× 37)正交表按设计组合后制备成 18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。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 5 5 ,对照毒饵的摄食系数为 0 5 1。现场灭鼠试验 ,优选毒饵的灭鼠率为 10 0 % ,对照毒饵为 79 0 %。结论 应用正交设计组合筛选灭鼠毒饵 ,方法可行 ;

Objective The orthogonal design was applied to the choice feeding test on field to screen on the combination of attractants of rodenticide baits and to evaluate the palatability of the trial poison baits and the mortality of the most suitable trail poison bait.Methods The orthogonal table L 18 (2 1×3 7) was selected.18 kinds of 0.005% bromadiolone trial poison baits combined by glucide,peanut oil,salt and alcohol on 2～3 levels of concentration and the control poison bait were tested in the choice trial on field,in which SPLM was implemented in analysis of variance.Results The 13 th trial poison bait was the most suitable,which feeding coefficient was 1.55,relatively that of control poison bait was 0.51.On the field poisoning test,the most suitable poison bait gave 100% mortality,but control poison bait 79.0%.Conclusion The field trial of screen on the combination of attractants of rodenticide baits by the orthogonal design was feasible;the mortality of the most suitable trail poison bait was better.
