Results All the 7 field populations were found to have developed resistance to DDVP and propoxur.
结果7个种群对DDVP和残杀威均产生了不同程度的抗性。
The conclusion is that this equipment is very sensitive for tsumacide, carbofuran, propoxur and so on, but not for methamidophos.
发现该仪器对部分农药，如敌敌畏、呋喃丹、速灭威以及残杀威有很好的检出灵敏度，但对甲胺磷的检出灵敏度最差；
Nanjing population were lowly resistant to propoxur (2.8 times) and sensitive to dichlorovos, while Nantong strains were susceptible to both propoxur and dichlorovos.
南京种群对残杀威低抗（2.8倍），南京种群对敌敌畏、南通种群对敌敌畏和残杀威均敏感。
