目的观察城市社区外环境灭鼠毒饵站的有效性。方法在黄石市6个社区外环境灭鼠毒饵站内分别投放0.005%的溴敌隆稻谷毒饵、大米毒饵、蜡质颗粒毒饵,用目测法观察毒饵站的有效性。结果 6个社区毒饵站平均有效率分别为93.13%、71.96%、69.31%、77.80%、47.78%、24.58%。投放蜡质颗粒毒饵的毒饵站有效率高于稻谷毒饵站(P<0.01),稻谷毒饵站有效率高于大米毒饵站(P<0.01)。每月补投毒饵社区的毒饵站有效率高于未补投毒饵社区毒饵站有效率(P<0.01)。毒饵站有效率与毒饵站灭鼠率具有相关性(r=0.676,P<0.01)。结论城市社区外环境毒饵站有效率与投放的毒饵种类及频次相关,定期补投毒饵、投放蜡质颗粒毒饵可提高毒饵站有效率。
Objective To observe the effectiveness of the rodent poison bait station outside the urban community. Methods The contents of 0.005% bromadiolone rice bait, rice bait and wax particle bait were respectively put into 6 community external environmental rodent bait stations in Huangshi City. The effectiveness of bait bait station was observed by visual inspection. Results The average effective rates of the six community bait stations were 93.13%, 71.96%, 69.31%, 77.80%, 47.78% and 24.58% respectively. The efficiency of the poison bait station put waxy bait station was higher than that of the rice bait station (P <0.01), and the efficiency of the rice bait station was higher than that of the rice bait station (P <0.01). The monthly effective rate of bait bait station was higher than that of bait station failed bait station (P <0.01). The efficiency of the bait station was correlated with the rate of rodent control at the bait station (r = 0.676, P <0.01). Conclusion The efficiency of poison bait station in urban community is related to the type and frequency of bait put in. The poison bait is regularly replenished and the waxy bait is put in to improve the efficiency of the bait station.
