| 摘 要： | １９９４－１９９５年，采用浸渍法建立了２２种杀虫剂对甘肃敦煌棉蚜的毒力回归线，可作为今后用浸渍法监测棉蚜抗药性的相对敏感毒力基线，与国内敏感棉蚜种群的毒力基线比较，１９９４年敦煌棉蚜对氰戊菊酯和灭多威处于敏感性水平，对氰化乐果和久效磷达到中抗水平（３１．４２和２７．４５倍），对溴氰菊酯达极高抗水平（２７４．３９倍）；对联苯菊酯、三氟氯氰菊酯、高效氯氰菊酯等药剂显示出早期抗性的迹象。１９９５年棉蚜对

| Abstract: | During 1994 1995,the cotton aphids(A phis gossypii Gbver) were collected from Dunhuang city,Gansu province,and were tested with twenty-two kinds of in secticides by means of leaf-dip method recomm ended by FAO(1980).The relative toxicity baseline of susceptibility for each insecticide to the aphids was established,whick can be used as the relatively suscep tible standard for comparisaon of tolerance of resistance level Compared with the toxicity baselines of insecticides to the susceptible cotton aphids in China,it was found that the aphids were suscep tible to fenvalerate and methomy1 in 1994,had already devebped middle levels of resistance to omethoate and monocrotophos(31.42 and 27.45-fold),and reached extremely high level of resistance to deltan ethrin(274.39-fo1d),had early-stage sign of resistance to biphenthrin,cyhabthrin and alphacyper methrin.In 1995,the aphids were also suscep tible to fenvalerate and methomy1,was middle level of resistance to monocrotophos(34.16-fold),achieved high level of resistance to omethoate(55.36-fold),and maintained extremly high level of resistance to deltan ethrin(303 66-fold). |
