稻纵卷叶螟的预测预报,主要采用田问赶蛾,查化蛹进度预测蛾盛期和卵孵盛期;查发蛾高峰及新虫包和卷叶尖出现情况,预测防治对象田和施药时间。实践证明,沿用一种调查方法进行预测,往往与实际发生情况出入很大,甚至会错过防治时机。因此必须中、短期预报相结合,特别是主要类型田新虫包和卷叶尖的检查,对于指导防治有重要意义。 Prediction and prediction of rice leaf roller, the main use of field moths, check the progress of moths to predict the moth peak and egg hatch peak; check the hair moth peak and the emergence of new worm package and roll tip predict the field of prevention and control Application time. Practice has proved that the use of a survey method to predict, often very different from the actual situation, and even missed the timing of prevention and treatment. Therefore, we must medium and short-term forecast combination, especially the main types of Tian new insect package and leaf tip inspection, for the guidance of prevention and treatment is of great significance.
