The response of Meriones shawi to seven rodenticides was investigated in laboratory feeding tests. The species proved to be much less susceptible to anticoagulants than most other species of rodent pests. Brodifacoum (at 0·005%), although giving complete mortality after only 8 days' continuous feeding, was more toxic than warfarin (0·025%), coumatetralyl (0·0375%), difenacoum (0·005%) and bromadiolone (0·005%). Calciferol (0·1%), though toxic, was significantly unpalatable. Zinc phosphide (5·0%) presented for 2 days in a choice test against unpoisoned food gave 80% mortality and appears to be the most suitable of these compounds for the control of M. shawi in the field.
