Abstract: Objective To compare the effect of 5 rodenticide baits (zinc phosphide at 1%, diphacinone Na-salt, warfarin and coumatetralyl all at 0.025%, bromodiolone at 0.005%) against Tscheskia triton in laboratory. Methods The choice-feeding tests were conducted for single T.triton by feeding 4 anticoagulant rodenticides for 4-days and zinc phosphide for 12 hours. The toxicity and palatability of tested rodenticides was evaluated with killing rate and feed coefficient. Results The killing rates of five rodenticide to T.triton were as follows: 88.89% for zinc phosphide, 100% for diphacinone Na-salt and Bromodiolone, 50% for coumatetralyl and 10% for warfarin respectively. The feed coefficients of zinc phosphide, diphacinone Na-salt, warfarin, coumatetralyl and bromodiolone were 0.73,0.38,0.64,0.56 and 0.81 respectively. Conclusion Other three rodenticides could be applied to control T.triton except for coumatetralyl and warfarin. However, considering control cost and practicability, diphacinone Na-salt was the best choice.
