豆秆黑潜蝇(Melanagromyza sojae)是汉中盆地夏大豆上的主要害虫之一。以前我区很少发生,自1980年以来,随着大豆的需求量不断增大,种植面积也随之增加,发生量逐年上升,为害日趋加重,特别是近两年来,豆秆黑潜蝇已成为汉中地区大豆生产上的障碍因素。自1988年以来,大豆苗期被害株率常在50%左右,严重的达80%以上,生长后期被害株率90～100%。现将我们对该虫的观察结果报告如下,供参考。

The stalk Melanagromyza sojae is one of the major pests on summer soybean in the Hanzhong Basin. In the past, my area seldom occurred. Since 1980, with the increasing demand of soybean, the acreage will also increase, the amount will increase year by year, the harm will be aggravated. Especially in the last two years, Become Hanzhong obstruction of soybean production factors. Since 1988, soybean seedling damage rate is often about 50%, severe up to 80%, the late growth rate of 90-100% victims. Now we observe the results of the worm as follows, for reference.
