Monitor of rodent density in Tai'an city in 2010

Objective To grasp the population composition and its seasonal fluctuation of rodent in Tai'an city,and provide scientific basis for developing mosquito control program.Methods Night trap method was used to monitor the rodent density.Results A total of 103 rodent were captured,with the average rodent density of 1.9%.Of which,the dominant specie was Rattus norvegicus(58%),and the density was 1.1%.The fluctuations of the rodent density followed a single-peaked curve,the peak value appearing in April.It was different from the seasonal fluctuations of the rodent density in different habitats.The rodent density in special industry was very high(2.6%).Conclusion The level of rodent density is high,and the main control targets are Rattus norvegicus in Tai'an city,so it should take the integrated measures to reduce the rodent density according to the characteristics of its breeding,habits and seasonal dynamics,and strengthen the surveillance,warning and measures of rodents and its diseases.
