摘  要：
Based on the monitoring data of agricultural rodent species from 1986 to 2010 in Yuqing County,Guizhou Province,the population composition and its fluctuation were elucidated herein.The agricultural rodents belong to 2 orders(Rodentia,Insectivora),3 families(Muridae,Cricetidae,Soricidae) and 7 species.Rattus norvegicus was dominant species among the residential rodents,accounting for 84.83% of the total.Apodemus agrarius mainly distributes in the rice field and dryland,accounting for 95.84%,87.43%,respectively,of the total.Apodemus agrarius was the dominant species of residential rodents.Population dynamics tended to decline in different years.The population dynamics varied highly among different months and seasons.Population dynamics peak was in May~June and October~ November.March and October were the best prevention and control period.
