牡丹江市周边农田啮齿动物种群数量及分布规律

摘要

为了解牡丹江市周边农田中啮齿动物种群数量和分布变化规律,以及对农业造成危害的主要害鼠种类及其生活习性,于2010年3-11月通过实地考察,利用夹日法、挖洞法、水灌烟熏法采集标本,结果表明,农田啮齿动物7种,隶属3目5科7属,黑线姬鼠（Apodemus agrarius）为主要优势种;啮齿动物的密度有2个高峰期,分别在6-7月和10月;黑线姬鼠和大仓鼠（Cricetulus triton）对农田危害最为严重,且有贮食行为。根据调查情况对害鼠提出防治措施,为预防鼠害提供科学依据。%The clip day,hole-digging,irrigating and smudging methods were used to collect the samples in the cropland regions of edge regions of Mudanjiang city for determining the population quantity and distribution regularity of rodents during the period from March to November of 2010.This study showed that 7 species rodents belonging to 3 orders,5 families,and 7 genuses were observed in this field survey.The Apodemus agrarius was the dominant species among all rodent species.The population density of rodents peaked in June-July and October.Apodemus agrarius and Cricetulus triton were the most harmful to cropland due to their food storage behavior.This study proposed the control measures for all rodents,which would provide scientific information for controlling rat trouble.
