营区鼠密度调查及灭鼠效果观察

The rodent density and effect of deratization in military barrack

目的调查驻济南部队营区鼠密度状况,考核灭鼠效果。方法采用饱和投毒法,0.005%溴敌隆小麦毒饵连续投毒4～5 d,粉迹法测定鼠密度确定营区鼠情和灭鼠效果。结果调查21个单位不同场所营区鼠密度,阳性房间率为2.5%,粉迹法阳性率为6.2%,有18个单位灭鼠前鼠密度超过国家除"四害"灭鼠标准。营区内以招待所(12.0%)密度最高,其次是食堂、伙房(9.2%),仓库、车库(8.4%)和围墙四周(8.2%)。通过0.005%溴敌隆大面积灭鼠,对10个灭鼠单位灭效考核发现,5个单位的灭鼠率达到100%,3个单位的灭鼠率在90%以上。结论通过多年灭鼠工作,济南部队营区鼠密度能有效控制在较低水平,灭鼠效果较好。

Objective To investigate rodent density and evaluate effect of killing in barrack of Jinan military.Methods Throwing wheat poison bait of 0.005% bromadiolone for 4-5 days,powder trace method was used to make sure the rodent density and the effect of killing rodent.Results The rodent density was investigated in different sites in 21 units.The rate of positive rooms was 2.5%,the positive rate of powder trace method was 6.2%.The rodent density of 18 units were more than the national standard before killing.The rodent density was highest in the guest house（12.0%）.The rodent density of other place of dining room and kitchen was 9.2%,warehouse and garage was 8.4% and aside the wall was 8.2%.The rodent killing rate was 100% in 5 units and 90% in 3 units after throwing 0.005% Bromadiolone in evaluating 10 units.Conclusion The rodent density can be controlled at lower level in barrack of Jinan military with killing rat work through several years.
