Efficacy of three anticoagulant rodenticides against Rattus rattus and Meriones libycus under laboratory conditions

Three anticoagulant rodenticides were used against Rattus rattus and Meriones libycus in choice and no choice feeding tests under laboratory conditions. In choice feeding tests, brodifacoum (0.005 %) and chlorophacinone (0.005 %) were more effective (P<0.05) than coumatetrahyl (0.0375 %) against R. rattus. Brodifacoum (0.005 %) and coumatetrahyl (0.0375 %) were more effective (P<0.05) than chlorophacinone (0.005 %) against M. libycus. In no choice feeding tests, coumatetrahyl (0.0375 %) and brodifacoum (0.005 %) were more effective than chlorophacinone (0.005 %) against M. libycus It was concluded that brodifacoum (0.005 %) was more effective against R. rattus while, coumatetrahyl (0.0375%) was more effective against M. libycus.
