Preliminary Report on Trap-barried System for Monitoring and Control Effects of Farmland Rodents

Effects of trap-barried system in farmland from 2010 to 2011 in Yuqing County,Guizhou Province were investigated in present paper.The results indicated three trap-barried system fences were set and 124 rodents were captured.The species of rodents were Apodemus agrarius,Rattus norvegicus,Mus musculus and Suncus murinus.Those composition and species of rodents coincided with the investigation results by the trap method.The average captured number was 24.80 per trap-barried system fence,and rodents captured during the former 2~3 months were more than that of the last 5~6 months.The control effect of rodents in corn fields and rice fields was 53.13%,the save loss rate was 1.87%.The cost of rodenticide application in local could be reduced by 38%.Therefore,trap-barried system may have a good application value in prevention and control of harmful rodents in farmland,and can be used to carry out the investigation and monitoring of rodent situation.
