| 中文摘要: |
| 为了明确陕西关中地区玉米生长后期钻蛀性害虫的为害情况及不同玉米品种的抗虫性，为玉米后期钻蛀性害虫的有效防治提供依据，在陕西关中选择5个具有代表性的县区进行调查，并且于2016年6月8-10日在阎良区种植21个玉米品种，观察不同品种的抗虫性。结果表明，陕西关中地区玉米生长后期钻蛀性害虫有亚洲玉米螟、棉铃虫和桃蛀螟3种，其所占比例因地而异。玉米后期钻蛀性害虫对21个供试玉米品种为害程度均较高，但不同品种之间受害程度有一定差异。 |
| 英文摘要: |
| This study aimed to clarify damage of corn borers in late stage of corn and different corn varieties resistant to these corn borers in central Shaanxi area, so that a basis of effective control strategies can be provided. The occurrence and damage of the corn borer were investigated in five counties in central Shaanxi area. Twenty-one corn varieties were selected to investigate the corn resistance to these borers. The results showed that three borer species, Ostrinia furnacalis (Guenée), Conogethes punctiferalis (Guenée) and Helicoverpa armigera (Hübner), occurred in central Shaanxi in late corn growth period and the species proportion differs from region to region. The tested twenty-one maize varieties were all severely damaged by these borers, while the damage levels were different among these varieties. |
