采用重捕标志法研究了棕背巢区,巢区面积7月份平均为250.89 m2,9月份平均为284.21 m2,雌雄间和季节间差异显著。棕背有集群分布现象。结合巢区面积和活动距离对鼠害防治布点规格与防治灭鼠率的关系进行了分析。
The reclaimed landmarks were used to study the brown-backed nesting area. The area of nesting area was 250.89 m2 in July and the average was 284.21 m2 in September. The difference between male and female was significant. Brown backfat has a cluster distribution phenomenon. According to the area and activity distance of nest area, the relationship between the specifications of rodent control and the rodent control rate was analyzed.
