Objective To select palatable rodenticide baits,so as to provide support for reducing time invested and improving rodent control quality in large-scale rodent control activities.Methods Wax block baits,rice baits,corn baits,wheat baits,and peanut baits containing 0.005%brodifacoum were each paired up with a type of bait base(naturally dried peanuts)in a 1∶1 ratio.The baits were placed in a saturated manner.Bait consumption was monitored and recorded consecutively for seven consecutive days.Analysis of variance and bivariate correlation analysis were performed.Results The 7-day cumulative feeding coefficient(FC)was 0.57 for the peanut baits,indicating good palatability;0.18 for the rice baits,0.18 for the wax blocks,and 0.17 for the corn baits,indicating moderate palatability;and 0.10 for the wheat baits,indicating poor palatability.There were significant differences in the 7-day cumulative FC of different baits in paddy field(F=25.340,P<0.001),residential area(F=5.667,P=0.002)and forest habitat(F=3.190,P=0.022),and the 7-day cumulative FC of peanut bait was the highest in the three habitats,which was 0.69,0.54 and 0.49,respectively.The corn baits also showed good palatability in residential areas with a 7-day cumulative FC of 0.41.Conclusion Before starting construction at construction sites in the eastern coastal area of Shanghai,China,peanut baits containing brodifacoum can be used for large-scale rodent control work,which can improve the efficiency of rodent control.
