下水道采用竹节法灭鼠效果探索

A field trial of the deratization effect by using "bamboo joints" in sewers

目的比较竹片法与竹节法灭鼠效果,探讨使用竹节法控制下水道(窨井)鼠类的效果以及观察鼠类对不同毒饵的拖食情况,为下水道灭鼠提供技术依据。方法①用竹节与竹片盛放毒饵,用相同饵料比较观察鼠类拖食率。②在竹节的每一格竹节中投放用蔗子、新鲜稻谷配成的0.005%溴敌隆毒饵以及溴敌隆蜡块,观察鼠类拖食情况。③在菜市场、餐饮店等行业周边下水道应用竹节法进行灭鼠效果评价。结果在菜市场周边的下水道获得的数据表明,竹节法拖食率(6.02%)高于传统竹片法的拖食率(1.39%),且二者差异有统计学意义(x^2=8.10,P<0.05);下水道鼠类对3种鼠饵的拖食率,蔴子饵为85.07%,其次是新鲜稻谷,蜡块的拖食率最低。结论竹节法在下水道(窨井)中的使用,具有良好灭鼠效果。

Objective To compare the efficacy of ＂bamboo strips＂ and ＂bamboo joints＂ baiting methods to control eommensal rodents that dwell the underground sewage in Shanghai, China. Methods （1）the foraging rate was compared between ＂bamboo strips＂ and ＂bamboo joints＂; （2）Observation was made to compare the foraging rate among the baits of Asako, fresh rice dubbed 0.005% bromadiolone bait and Bromadiolone wax blocks; （3）Trails were conducted in the underground sewage system adjacent the groceries and restaurants. Results Data from underground sewage system adjacent the groceries and restaurants indicated that the foraging rate in ＂bamboo joints＂ method （6.02%） was significantly higher than traditional ＂bamboo strips＂ method （1.39%） （X2=8.10, P〈0.05）, the rodent populations dwelling in underground sewage systems showed a foraging rate of 85.07% on Asako, followed by that on fresh rice dubbed with bromadiolone bait and then bromadiolone wax block. Conclusion The ＂bamboo joints＂ method was recommended for rodent control in underground sewage system by baiting.
