| 摘 要： | 通过对采自我国内蒙古丰镇县13个春小麦病株标样进行4种蚜虫连续传毒比较,不同温度饲毒和接种试验,薄膜饲毒,2种蚜虫成若蚜传毒比较和血清学酶标试验等,明确我国内蒙古丰镇县小麦黄矮病毒株系为由麦二叉蚜和麦长管蚜有效传播的麦二叉蚜麦长管蚜株系(GAV)。对于这个株系,禾缢管蚜与玉米蚜是不能传播的。这种株系在我国冬麦区春麦区都有分布。

| Abstract: | Based on biological tests such as the comparative transmission by means of 4 aphid species,the comparative transmission after acquisition and inoculation at different temperature,the comparative trans-mission after acquisition virus through membrane on purified virus preparations by means of 4 aphid species and transmission by adults and nymphs of greenbug and English grain aphids,and ELISA assays.The 13 isolates of WYDV collected from spring wheat field in Nei Menggu Fengzhen county in 1984 could be identified as GAV.The GAV is transmitted very effectively by greenbug and English grain aphid but not by the oat bird-cherry aphid and the corn leaf aphid.The strain is now known to be present in winter and spring wheat area in northern China. |
