| 摘 要： | 用点滴法系统监测了河北省主要棉区广平县、冀县、辛集市、献县和定兴县的棉铃虫对常用杀虫剂主要品种的抗药性。各地棉铃虫对溴氰菊酯的抗性逐年增加，由１９９１年的１０－３１倍增加到１９９５年的２００倍以上。对久效磷的抗笥也呈逐年增加的趋势，由１０－２２倍增长到４０倍以上。对辛硫磷和对硫磷，各地棉铃虫的敏感性缓慢地逐年下降，至１９９５年，敏感性降低４－１１倍，处于敏感性明显降低和产生代度抗性之间。对于另一种

| Abstract: | The resistance to some conventional insecticides of Heliothis armigera in Hebei province was monitored in 1991 ~ 1995. Every year, the adults were captured in Guangping,Jixan, Xianxan, Xinji and Dingxing, and their off-spring larvae were used for assay with the topical application method. In the 5 years, the resistance of the insect on various places to decamethrin was increased rapidly from 10~31 fold to more than 200 fold, and resistance to monocrotophos increased from 11 ~ 22 fold in 1991 to more than 40 f0ld in 1995. To parathion and phoxim, the susceptibilities of H. armigera lowered showly by 4~ 11 fold.Constant susceptibility of the insect to methomidophos was maintained in all the places. In most places, H. armigera have got resistance of more than 10 fold to methomyl by 1995. |
