棉蚜对几种杀虫剂抗性的监测

１９９１～１９９５年系统监测了河北省广平、冀县、献县、辛集和定兴棉蚜对几种常用杀虫剂的抗药性。５年内，各地棉蚜对溴氰菊酯的抗性在１１００～１７０００倍的超高抗范围内波动；对久效磷、氧化乐果和呋喃丹的抗性多在１０～４０的中抗范围，个别年份及个别地区为低抗或高抵。５年内，棉蚜对上述３种药剂的抗性无明显发展。对另一种氨基甲酸酯类杀虫剂涕灭威，各地棉蚜仍基本上敏感。不同地区棉蚜的抗药性水平无明显的差异。

Insecticide-Resistance Monitoring of Aphis gossypii in Hebei Province

The resistance of Aphis gossypii to some conventional insecticides in Guangping,Jixan, Xianxan,Xinji and Dingxing in Hebei province was monitored in 1991-1995.In these 5 years,the resistance levels to decamethrin of Aphis gossypii in all the places varied in a range of 1100-17000 times.The resistance to monocrotophos,omethoate and carbofuran of the insect was in a range of 10-40 times in majority and no significant increase to the 3 insecticides.Aphis gossypii kept susceptible to aldicarb.There were no significant differences in the insecticide-resistance levels among the different places.
