达乌尔鼠兔发生规律及防治技术研究

多年调查研究发现,达乌尔鼠兔在定西地区每年可繁殖2~3胎,每胎产仔数3~5只,平均4.12只。日活动呈明显的双峰型,全年活动主要集中在5~10月,9月和10月是最高峰。烟雾炮熏杀,弓型夹、平板夹捕杀、防啃剂喷涂树干等防效较好,生物控制也是一种有效的辅助防治措施。

Research on Control Technique and Occurrence Regularity of Ochtona daurica

Based on the investigation and survey for many years,the results showed that Ochtona daurica repro-duced 2 to 3 embryo each year in Dingxi region,and delivered 3 to 5 at a litter,an average of 4.12.Daily activity is ob-viously bimodal,the annual event mainly concentrated from May to October,September and October were prominent peak.The methods of fumigating with gun-smoke,clamping bow,hunting with clamping plate,and daubing anti-snaw-ing medicament over tree trunks had better control effects,biological control was also an effective secondary prevention measures.
