摘要: 目的评价长期使用敌鼠钠盐的地区敌鼠钠盐对黄胸鼠的毒杀效果。方法现场使用不同浓度毒饵进行7d饱和投药。结果0.10%和0.16%稻谷毒饵的盗食率分别为35.99%和26.21%,灭效分别为79.44%和92.70%。0.10%小麦毒饵的盗食率和灭效分别为38.36%和85.92%。2种稻谷毒饵的盗食率差异有显著性(χ2=12.97,P<0.01),灭效差异无显著性(χ2=0.32,P>0.05)。相同浓度的敌鼠钠盐稻谷和小麦毒饵之间盗食率和灭效差异均无显著性(χ2=0.64,P>0.05;χ2=0.03,P>0.05)。结论该地使用敌鼠钠盐防制黄胸鼠仍有良好效果,不宜盲目提高药物的使用浓度,但灭鼠药物的轮换使用应予以重视。

Abstract: Objective To evaluation the efficiency of Diphacinon Na against R.flavipectus in area of Diphacinon Na applied for a long time.Methods A saturated Diphacinon Na bait was applied at different baits for a 7 day period in field test.Results Paddy with this rodenticide at 0.10% and 0.16% the feeding rates of R.flavipectus were 35.99% and 26.21%,the killing rates were 79.44% and 92.70%.The feeding rate and killing rate for R.flavipectus were 38.36% and 85.92% at 0.10% wheat bait treat ment.The feeding rate showed significant difference(χ2= 12.97,P< 0.01)and the killing rate showed no statistical significance(χ2=0.32,P>0.05) between 0.10% and 0.16% paddy bait.The feeding rate and killing rate showed no significant difference(χ2= 0.64,P>0.05,χ2= 0.03,P>0.05) between 0.10% paddy bait and 0.10% wheat bait.Conclusion The killing effect still was well and blindly raise the concentration of bait was not suitable for Diphacinon Na against R.flavipectus.But for switched rodenticides application should be paid more attention.
