摘　　要：为明确冀中南小麦—玉米连作田黑麦秆蝇的简便高效防控技术,设置了冬小麦分期播种、夏玉米种子处理及苗期喷雾等试验。结果表明:冬小麦晚播控害效果明显,可在显著降低黑麦秆蝇麦田危害的同时压低虫源基数;后期若进行夏玉米连作,可选用高剂量噻虫嗪种衣剂进行种子处理、2叶期或4叶期结合苗期除草使用噻虫嗪喷雾等措施可进一步减轻危害。In order to clarify the simple and effective control technology of rye stem fly in wheat and corn field in central and southern China,the effects of phased sowing,summer maize seed treatment and seedling spraying were tested.The results showed that the control effect of late sowing of winter wheat was obvious,which could significantly reduce the harm of rye stem fly in wheat field and reduce the insect source base at the same time;Late summer corn continuous cropping,high doses of thiacream seed coating agent could be used for seed treatment,2 leaf stage or 4 leaf stage combined with seedling stage weeding and thiazoxam spray to further reduce the harm.
