摘要
目的测试几种常见武汉市售鼠药对褐家鼠和黄胸鼠药效。方法在实验室做无选择摄食实验,测试8种鼠药对褐家鼠及3种鼠药对黄胸鼠的药效。结果除1号鼠药毒杀率达80%外,其他7种鼠药对褐家鼠毒杀率均达100%。1号、3号鼠药对黄胸鼠毒杀率10%,经χ2检验它们与该鼠药对褐家鼠毒杀率相比有极显著差异(χ2=9.90和16.36>χ0.01=6.63)。6号鼠药毒杀率为70%与该鼠药对褐家鼠毒杀率相比无显著差异(χ2=3.53<χ0.05=3.84)。结论黄胸鼠比褐家鼠更能耐受某些鼠药,在以黄胸鼠为主的地点灭鼠可以选用6号灭鼠剂或增加鼠药在现场留存时间。
Objective To study the effect of common used rodenticides in Wuhan against Rattus norvegicus and Rattus flavipectus. Methods No-choice dieting test in laboratory. Eight kinds of rodenticides against Rattus norvegicus and 3 rodenticides against Rattus flavipectus were tested. Results The death rate of No. 1 rodenticides to Rattus norvegicus was 80% , and which of the other 7 rodenticides were 100%. The death rate of No. 1 and No. 3 rodenti- cides to Rattus flavipectus were 10%, the difference between them and the death rates of the respective rodenticides to Rattus norvegicus were remarkable （ X^2 = 9. 90 and 16. 36 〉 X0 01 = 6. 63 ）. The death rate of No. 6 rodenticides to Rattus flavipectus were 70% , and the difference between it and the death rates of the rodenticide to Rattus norvegicus was not remarkable （ X^2 = 3.53 〈 X0.05 = 3. 84 ）. Conclusion Rattus flavipectus were more endurable to some rodenticides than Rattus norvegicus. No. 6 rodenticide could be selected or keep for longer time in rodent control when infested mainly with Rattus norvegicus.
