谷子钻蛀性害虫在我省发生普遍而严重,对谷子的生产威胁很大,且最难于防治.这类害虫常年为害率平均为10-20%,其为害程度与导致产量损失的关系过去报道甚少.近两年来我们以当地谷子钻蛀性害虫的主要种类为对象,进行了自然感虫和人工模拟产量损失试验研究,取得了良好结果.为拟定防治指标提供了依据. Mildew boring sex insects in our province is widespread and serious, the threat to the production of millet large, and the most difficult to control. Pests perennial damage rate of 10-20% on average, the degree of harm and lead to yield loss in the past reported Very few.In the past two years, we took the main species of the local moth borer pests as the object, carried out natural insects and artificial simulated yield loss experimental study, and achieved good results for the formulation of control indicators provide the basis.
