赣州市区家栖鼠类群落结构及季节消长研究

The Study of Community Structure and Seasonal Fluctuation of Commensal Rodents in Ganzhou Urban Area

目的了解赣州市区鼠类群落结构变化及其原因。方法夹夜法。结果共捕鼠297只,隶属2目2科3属4种,其群落结构为褐家鼠+小家鼠+臭+黄胸鼠,以褐家鼠和小家鼠为主要构成,鼠密度平均为3.09%。市区家栖鼠全年数量变动曲线出现初春(3～5月)与夏末(8～10月)两个高峰。结论赣州市区鼠类以褐家鼠和小家鼠为主要防制对象。

Objective To investigate the change of Rodent Community Structure and the cause, to provide basis for controlling the rodent density. Methods The method of night trapping. Results ~297 rodents were captured, belong to 4 Species 3 genus 2 families and 2 orders. The community structure are: Rattus norvegicus+Mus musculus+Suncus murinus+Rattus flavipectus.The rat density was ~3.09% , Rattus norvegicus and Mus musculus were predominant species. The yearly seasonal fluctuation of the population amount are two peak periods of the population amount in early spring and later summer (March to May and August to October). Conclusion Rattus norvegicus and Mus musculus will be control as a leading role in Ganzhou Urban Areas.
