Abstract: Objective To study the rodent species composition and population dynamics for providing scientific basis to rodent control.Methods To capture rodents with trapnight for rodent specimen at the same period of each month from 2001-2005 in residential area,rice field and dry farm land.Results The results showed that Apodemus agrarius is a dominant mouse species,which takes up 89.97% of total number of all rodents species in field.The mean pregnancy rate,litter size and reproductive index of eight years were 26.97%,5.14 and 0.66 respectively.According to the body weight and reproductive characters,the control counter measures has been put forward based on the occurrence rule and prevention technique in recent years.Conclusion Apodemus agrarius are the target rodents for surveillance and control;March and August are the key periods for rodent control.Chemical control is one of the main rodent control measures.
