1992～ 1 994年在西华县分别设置了棉铃虫综合治理区和化学防治区。治理区连续 3年实施棉铃虫综合治理技术 ,化防区全部实施化学防治措施。至 1 994年 ,治理区棉铃虫对功夫菊酯、来福灵和灭多威的抗性分别为 1 992年的 0 .71 ,0 .58和 0 .41 ,对敌杀死、甲胺磷和甲基 1 60 5的抗性有所上升 ;而化防区棉铃虫对测试药剂的抗性均有不同程度增长。表明综合治理对延缓棉铃虫抗性发展具有较好效果
1992-1994 in Xihua County, respectively, set up a comprehensive management of bollworm and chemical control areas. Management area for three consecutive years of implementation of integrated management of cotton bollworm, chemical prevention and control zones all the implementation of chemical control measures. By1994, the resistance of H. armigera in the control area to cyhalothrin, leflunomide and methomyl were 0.71, 0.58 and 0.41 in 1992, respectively, killing the enemy, methamidophos And the resistance of methyl 1 60 5 increased. However, the resistance of H. armigera to test agents increased in varying degrees. The results showed that comprehensive treatment had a good effect on retarding the development of cotton bollworm resistance
