目的 :研究毒饵盒对提高灭鼠效果的作用。方法 :采用自制毒饵盒与传统塑料饵袋灭鼠 ,分别对多年灭鼠仍保持一定密度、灭鼠难度较大的局部地区进行灭鼠效果对比评价。结果 :毒饵盒法盗食率为 43 .0 % ,毒饵袋法为2 0 .0 % ;经 15 0d灭效观察 ,试验区鼠密度 (粉迹法 )下降率 94.3 6% ,对照区仅为 69.2 9% (u =2 .896,0 .0 0 5 >P >0 .0 0 2 ) ;灭效RPI指数为 18.3 7。结论 :毒饵盒法的鼠类盗食率较高 ,现场灭鼠效果明显优于传统毒饵袋法
Objective: To study the effect of bait box to improve the anti-rat effect. Methods: The homemade bait box and traditional plastic bait bag were used to rodent the rats, respectively. The rodent control effect was evaluated in some areas where rodent control still maintained a certain density for many years, and rodent control was more difficult. Results: The poisoning rate was 43.0% in the bait box method and 20.0% in the bait bag method. After 15 days of inactivation, the decreasing rate of the mouse density in the experimental area was 94.36%, while that in the control area was only 69.2 9% (u = 2 .896,0 .0 0 5> P> 0 .0 0 2); the extinction RPI index was 18.37. Conclusion: The bait box method has higher rodent feeding rate, and the rodent control effect is better than the traditional bait bag method
