目的比较烟炮、磷化铝和溴敌隆毒饵3种灭鼠方法对二连浩特口岸地区鼠类控制效果。方法室内采用粉迹法、室外采用堵洞查盗法调查鼠密度;口岸地区物流仓库采用综合防治;野外长爪沙鼠危害区分别采用烟炮、磷化铝熏蒸处理和一次性饱和投放溴敌隆大米毒饵进行控制。结果物流仓库鼠密度为15.85%,野外3个样方鼠密度在19～23洞/hm~2之间。物流仓库灭鼠效果为89.53%;野外3个现场灭鼠效果均为100%。结论口岸地区室内采取综合防治措施,室外采用毒饵、烟炮和磷化铝熏蒸处理可取得理想灭鼠效果,在应急情况下,加大1倍用量可完全控制鼠害。
Objective To compare the rodent control effects of three kinds of rodenticides, namely, guns, aluminum phosphide and bromadiolone bait, on Erenhot Port. Methods The indoor density was determined by the method of chalking method and the density of stool holes was used outdoors. The integrated control of the logistics warehouse in the port area was adopted. The hazard zone of wild gerbils in the wild gerbils were treated with flue gas, aluminum phosphide and fumigated with one- Long rice bait control. Results The density of rat in logistics warehouse was 15.85%, and the density of 3 quadrats in field was between 19 and 23 holes / hm ~ 2. The rodent control effect of the logistics warehouse was 89.53%; the field rodent control effects were 100% in the field. Conclusion The comprehensive prevention and control measures are taken in the interior of the port area. Fumigation treatment with poison bait, smoke gun and aluminum phosphide can achieve the ideal rodent control effect. In case of emergency, increasing the dosage of 1 times can completely control the rodent pests.
