Palatability of different rodenticide baits at large construction sites in the eastern coastal area of Shanghai,China
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.
