一代二化螟的预测预报,一般只以稻田禾蔸虫量为依据进行。这样只能预测前期蛾峰,后期蛾峰往往预测不到。为了探讨更合理的测报方法,获得较准确的预测结果,笔者于近几年在临川县湖南乡对越冬二化螟的虫源分布及发育进度作了较为详细的调查, The prediction and forecast of the generation of striped stem borers are generally based on the amount of grasshoppers in the paddy field. This can only predict the early moth peak, post-moth often unpredictable. In order to explore a more reasonable method of measuring and obtaining more accurate prediction results, the author made a more detailed investigation on the distribution and development of the borer, Chilo suppressalis, in Hunan Province in Linchuan County in recent years.
