麦种蝇在陕西关中地区,近几年来,为害日益严重。从1960年4月以来,我们对麦种蝇的生活史、习性、犯獗的原因及其防治进行了研究。证明小麦受害程度和栽培技术有密切的关系。栽培技术影响小麦的生长发育及麦田小气候;同时也影响麦稈蝇的活动、取食、繁殖和为害。改进栽培技术,促进小麦生长发育是防治麦稈蝇的有效措施。一、播种期:播种期与麦稈蝇为害的关系,在不同季节表现有明显差別。秋苗期,播种早的受害重。根据对南大2419,612,6028,碧玛1号等四个品种的调查,凡9月播种的小麦,秋苗被害株率达25.1％;—54.0％;10月上中旬播种的被害株率
Wheat species flies in Shaanxi Guanzhong area, the damage in recent years, increasingly serious. Since April 1960, we have conducted a study on the life history, habits, causes and prevention of wheat germ. Prove the degree of wheat damage and cultivation techniques are closely related. Cultivation techniques affect the growth and development of wheat and microclimate in wheat fields, but also affect the activity, feeding, reproduction and damage of wheat flies. Improving cultivation techniques to promote the growth and development of wheat is an effective measure to prevent and control wheat flies. First, the sowing period: sowing date and the relationship between the harm of straw flies in different seasons showed significant differences. Autumn seedlings, sowing early victims heavy. According to the investigation of four varieties of Nanda 2419, 612, 6028 and Pima 1, the rate of the victim plants seeding in September was 25.1% and 54.0%
