To screen suitable anticoagulant rodenticides for pest rodent control in rural areas of southern Xinjiang,we tested the control efficacy of coumatetralyl,bromadiolone,and brodifacoum on pest rodents using three kinds of evaluation methods,including snap-trap,food consumption,and powder trace,in Shule county,Kashi.We also evaluated the safety of rodenticides for Gallus domestiaus and Columba livia by gavage.The results showed that the control efficacy of coumatetralyl and bromadiolone reached a similar level 10 days after successive bait delivery,including the percentage of positive blocks and the consumption of normal wheat.In the coumatetralyl zone,we found a higher percentage of households along with decreased wheat consumption and lower percentage of Rattus norvegicus in captured pest rodents,compared with the bromadiolone zone.However,the consumption of rodenticide was higher in coumatetralyl zone.The control efficacy of bromadiolone alone for 30 days reached 90.9％,while the control efficacy was only 65.9％using the control strategy of 10-day bromadiolone and 20-day brodifacoum.The toxicity level of rodenticides to local poultry,e.g.,chicken and pigeon,from low to high followed the order of coumatetralyl,bromadiolone,and brodifacoum.Therefore,coumatetralyl and bromadiolone are suitable for rodent control in the rural areas of southern Xinjiang.
