若干春小麦品种对灰翅麦茎蜂的自然抗性鉴定

Identification of the Natural Resistance of Several Spring Wheat Varieties to Cephus fumipennis Eversmann

以田间随机区组试验法鉴定了 1 3个春小麦 ( Triticum spp.)品种对灰翅麦茎蜂 ( Cephus fumipennisEversmann)的抗性。其中 ,永粮 1 2、高原 3 56、阿勃、互助红和辐射阿勃 1号对灰翅麦茎蜂的幼虫蛀茎危害的相对感性值较低 ,证明这 5个品种具有比其它品种较强的抗虫性。

The resistance of 13 spring wheat varieties to Cephus fumipennis Eversmann was measured in rendomized block designed field experiments.Compared with the others of the tested varieties, the relative susceptibility of Yongliang 12,Gaoyuang 356,Abbo., Huzhuhong, and Fushe Abbo.1 to the stem boring injury of the larval C.fumipennis were lower, showing that these 5 varieties possess higher resistance to the insect pest.The spring wheat varieties originated from Abbo. should be chosen to conduct the control of the pest.
