| 摘 要： | １９９０～１９９５年间在陕西渭南、三原、大荔棉区，采用毛细管点滴法测定了棉花苗蚜对九种常用有机磷及菊酯类杀虫剂的抗药性。结果表明，与敏感种群相比，陕西各棉区苗蚜对有机磷类杀虫剂基本处于敏感水平；对久效磷的抗性相对较高，其ＲＲ值为２．５～４．５．对菊酯类杀虫剂则表现出极高的抗药性，１９９５年测定发现，对溴氰菊酯的ＲＲ值高达１３４５７１；而对氯氰菊酯则相对敏感些，三原苗蚜仅为１４．３６；而渭南苗蚜种群则高达１６４．８６

| Abstract: | The resistance of cotton bud aphids ( Aphis gossyppii Glov.) to several insecticides was detected by means of topical application during 1990 to 1995 in the counties of Weinan,Sanyuan and Dali,Shaanxi Province.The results showed that,compared with sensitive strains,all these aphids were generally sensitive to OPS.The most resistable one was monocrotophos,with a resistance index of 2.5-4.5. However,to pyrethroids,much resistance existed.The result of the investigation in 1995 indicated that the most resistable one was decamethrin whose resistant index was 134571,and to other ones,cyhalothrin 13577,and fenvalerate 2103. But to cypermethrin,the bud aphids were comparatively sensitive. |
