目的为推广溴敌隆新剂型,掌握溴敌隆颗粒毒饵使用技术,给今后大面积灭鼠提供良好的交替更换杀鼠剂。方法在贵州省余庆等5县(区)对0.005%溴敌隆颗粒毒饵防制家栖及农田鼠类进行药效试验。结果0.005%溴敌隆颗粒毒饵对住宅区褐家鼠、黄胸鼠、农田黑线姬鼠的适口性较好,且具有很好的安全性。投药后15d,对家栖和农田鼠类的平均防制效果分别为84.23%和85.72%,平均取食率分别为31.99%和33.20%。各示范区农田大面积防制效果均达80.00%以上。结论0.005%溴敌隆颗粒毒饵是一种较理想的商品毒饵,可以作为贵州省重点地区大面积灭鼠的首选交替杀鼠剂推广使用。
Aim To promote the development of new formulations of bromadiolone and to master the use of bromadiolone baits, it will provide a good alternative to rodenticides for large-scale delustering in the future. Methods In the five counties (districts) such as Yuqing in Guizhou Province, the efficacy test of 0.005% bromadiolone bait was used to control the home and farm animals. Results 0.005% bromadiolone baits had good palatability with Rattus norvegicus, Rattus flavipectus and Agkistrodon acutus in residential area and had good safety. The average control effect on domesticated and farmland rodents was 84.23% and 85.72% respectively on the 15th day after dosing. The average feeding rates were 31.99% and 33.20% respectively. The demonstration area of farmland control effect of large area reached 80.00%. Conclusion 0.005% bromadiolone bait is an ideal commercial bait, which can be used as the first choice of alternative rodenticide in a large area in Guizhou Province.
