衢县为大、小麦混作区。大麦一般比小麦和其它作物成熟期早,是春季农田鼠类的主要食物源。鼠害在夏熟作物中亦以大麦较为严重,田间株受害率达5—20%。危害大麦的鼠类以黑线姬鼠(Apodemus aqrarius)为优势种群。据1986—87年大麦生育期间农田7956夹次的调查,捕获鼠类260只,黑线姬鼠占74.2%,褐家鼠、黄胸鼠等其它五个鼠种共占25.8%。为了解鼠类在大麦田的取食行为,提供合适的鼠害抽样技术,笔者等对大麦田鼠害株的田间
Qu County, wheat mixed area. Barley, generally mature earlier than wheat and other crops, is the main source of food for the spring farm mice. Rodents are also more serious in barley crops in summer, the damage rate of field strains of 5-20%. Rodents that endanger barley dominated Apodemus aqrarius. According to the survey of 7956 farms during 1986 to 1987 barley, 260 rodents were captured, Apodemus agrarius accounted for 74.2%, and other five rodents such as Rattus norvegicus and Rattus flavipectus accounted for 25.8%. In order to understand the feeding behavior of rodents in the barley field and provide appropriate rodent sampling techniques,
