Abstract: 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.
