摘要
采用点滴法测定了山西晋中、临汾、运城地区麦长管蚜对5种有机磷杀虫剂的敏感性。结果表明,以LD50值比较,晋中地区麦长管蚜的敏感性次序为氧化乐果>辛硫磷>马拉硫磷>敌敌畏>乐果;临汾地区的敏感性次序为马拉硫磷>氧化乐果>辛硫磷>敌敌畏>乐果;运城地区为马拉硫磷>氧化乐果>辛硫磷>乐果>敌敌畏。3个地区相比较,对各种杀虫剂的敏感性以运城最为敏感,其次为临汾、晋中地区。
Susceptibility of Sitobin avenae Fab to 5 Organophosphorous insecticides in Jinzhong,Linfen and Yuncheng regions of Shanxi was tested. The results showed that compared at LD50 sensitivily order of Jinzhong strain was omethoate>phoxim>malathion>dichlorovos>dimethoate. Lin fen strain was malathion>omethoate>phoxim>dichlorovos>dimethoate, and Yuncheng strain was malathion> omethoate>phoxim>dimethoate>dichlorovos. Yunchng strain was the most susceptible to each of the five organophosphorous insecticides, followed by Linfen and Jinzhong Strains.
