农田黑线姬鼠发生规律与防治技术

１９８５￣１９９５年１０年监测结果表明，黑线姬鼠为浙江农田优势种，每年４￣５月和９￣１０月为繁殖高峰期，６月和１０￣１１月为数量高峰。冬前冬后密度基数，种群年龄结构，繁殖力，温度，降水，天敌和药剂防治是影响种群数量变动的主要因子及预测的依据。根据害鼠密度与稻麦为类损失率及经济允许水平，提出主害期控制的鼠密度指标为：大小麦２．７％￣４．４％，早稻４．６％￣６．７％，晚稻６．９％￣８．４％，防治指标为

STUDY ON THE OCCURRENCES AND CONTROL TECHNIQUES OF STRIPED FIELD MOUSE IN FIELD

The monitoring results from 1985 to 1995 showed that striped field mouse is a advantageous species in Zhejiang Province. The maximum reproductive rate of the mouse is from April to May and from September to October every year , highest density in June and from October to November . Main factors, which affect population dynamics , are population density before and after overwintering, age components in population, reproduction, temperature, rainfall, natural enemies and chemical spray, these are also main basis for prediction of the mouse activities. According to the mouse density, the measurements of loss rates of rice and wheat,and economical injuring level,it is presented that the mouse density criteria in main damage stage on wheat and barley: 2. 7 % - 4. 4%, on early rice 4. 6%- 6. 7% ,6. 8% - 8. 4% on later rice, the criteria is-the mouse density 3% in early spring. Bromadiolone, Diphacin-Na-salt Cumatetragl are effective chemicals to the mouse, and can be made as baits for using in integrated rat managements.
