| 中文摘要: |
| 对甘肃、青海地区春、冬小麦麦茎蜂及其天敌发生情况进行调查，发现灰翅麦茎蜂(Cephus fumipennis Eversmann)在甘肃地区的平均危害率为7.9%，在青海地区平均危害率为12.5%。调查发现，灰翅麦茎蜂天敌以镜面茎姬蜂(Collyria catoptron Wahl)为优势种，甘肃地区天敌寄生率为9.6%，青海地区仅为1.6%。有针对性地对麦茎蜂的发生原因进行了分析，提出了以天敌保护利用、抗虫育种为主的综合防治措施。 |
| 英文摘要: |
| The occurrence of Cephus spp.and their natural enemies on the spring wheat and winter wheat in Gansu and Qinghai was investigated.The results showed that the average damage rate by C.fumipennis was 7.9% in Gansu, while the rate was 12.5% in Qinghai.The dominant natural enemy of Cephus spp.was Collyria catoptron Wahl, and its parasitic rate was 9.6% in Gansu, but only 1.6% in Qinghai.The causes for the occurrence of Cephus spp.were also analyzed, and comprehensive control measures that mainly depend on the protection and utilization of natural enemies and insect-resistant breeding were finally put forward. |
