谷子钻心虫(即一代玉米螟虫)是谷子苗期重要蛀食性害虫。从1983～1985年应用期距预测法对谷子钻心虫的防治适期进行了预测预报及指导大田防治。一、防治适期根据谷子钻心虫的生活规律,通常把田间螟卵孵化的始盛期作为防治适期指标。但是,这个指标调查难度较大,时间性强,不易提前预测。然而,通过对多年玉米螟各虫 Barley borer (ie, a generation of corn borers) is an important pest-eating pest at the seedling stage of the millet. From 1983 to 1985, the application of the interval prediction method for the control of millet borer suitable period for forecasting and guidance field control. First, the control period According to the law of life of millet worms, usually the beginning of the field borer hatching as the control index. However, this index survey is more difficult, timeliness, not easy to predict in advance. However, the worm passed on the corn borer for many years
