溴敌隆颗粒与蜡块毒饵灭鼠效果现场评价

Field Evaluation of the Effect on Rodent Controlling with Granular and wax Block Bait of Bromadiolone

以0.005%溴敌隆颗粒毒饵,采用1、1、2间隔饱和投饵法(投放3次及6次)与连续5天饱和投饵法,对城乡家鼠大面积杀灭效果达88.64%～93.21%;同时采用1、1、2间隔饱和投饵法(投放6次),投放0.005%溴敌隆蜡块毒饵于居民住宅与企事业单位混合区,平均灭鼠率为76.07%。两种剂型的安全性良好,并对常见家鼠(褐家鼠、黄胸鼠、小家鼠)和臭鼩均有杀灭效果。建议在群众性灭鼠时,宜多采用间隔饱和投饵,以期提高灭效;蜡块毒饵的配方与制作工艺应予改进;在计划灭鼠时,应同时考虑灭蚤问题,以防止有关传染病的传播发生或回升。

Using granular toxic bait containing 0.05% bromadiolone with either 1.1.2 pulsed surplus baiting (disposed three and six time)or continuing surplus baiting for five days, 88.64～93.21% control rate was achieved in wide area of urban and countryside. In ling the region mixed with dwelling houses and enterprises, the average, 76.07% control ling rate was observed with wax block toxic bait containing 0.005% bromadiolone applied as 1.1.2 pulsed surplus baiting (disposed six times). Both forms of toxic bait were proved to be of safety, and were effective in killing domestic rodents(R. norvegicus, R. flavipectus and M. musnulus) as well as S. murinus. It is proposed that: pulsed surplus baiting would be more efficient for enhanre the controlling effectiveness in massive rodent controlling; the ingreaient and manufacture technology of wax block bart should be improved, and the elimination of flea should be included in rodent controlling program so as to prevent the occurance or increasing of infectious diseses.
