Abstract: Objective To observe the toxicant efficiency of Bromadiolone against R.flavipectus.Methods The choice and nonchoice feeding tests of different baits to R.flavipectus were conducted in laboratory.Three-day pulsed baiting was conducted in field.Results The feeding indice of R.flavipectus were 0.88,0.73,1.11 and 0.13 to 0.005% wheat bait,rice bait,paddy bait and granular bait in choice feeding tests.One-day and four-day nonchoice feeding tests of 0.005% wheat bait,rice bait and paddy bait,the death rates of R.flavipectus were no more than 30%.Two-day nonchoice feeding test of 0.005% granular bait,the death rate was 80%.Two-day and three-day nonchoice feeding tests of 0.01% wheat bait,the death rates were 60% and 75%.The field test of 0.015% wheat bait against R.flavipectus,the killing rate was 93.02%.Conclusion The palatability of 0.005% fresh Bromadiolone bait were well.But the killing effect were bad for R.flavipectus.The quality of Bromadiolone was worth to evalue.
