以黑线姬鼠各月捕获数分别占全年总捕获数百分率的曲线表现为:一年中存在后峰突出的双峰型消长规律。黑线姬鼠在玉米地里,播种期和乳熟期活动密度较大,捕获率分别为6.75％,和6.5％;在水稻田里则孕穗期密度最大,捕获率为8.33％,呈基本对称的单峰型。表明在作物地黑线姬鼠随食物变化进行季节性转移,其规律是:小麦地→刚播种的玉米地→孕穗稻田、成熟玉米地→红薯地。
The curve of the monthly total number of captured semen of Apodemus agrarius in each month was as follows: the bimodal pattern of declining peak appeared in one year. Apodemus agrarius in the corn field, sowing and milking stage activity density, capture rate was 6.75%, respectively, and 6.5%; in paddy field is the highest density at booting stage, capture rate was 8.33%, showed a basic symmetry Of the unimodal type. The results indicated that the Apodemus agrarius in the crop had seasonal changes with the change of food, the regularity was: wheat land → freshly planted corn land → booting rice field and mature corn land → sweet potato land.
