近十年来，二化螟种群迅速上升。据宿松县30a螟虫发生为害测报调查资料分析，水稻二化螟近年发生特点是：越冬场所广，基数大；发育极不整齐，蛾峰多，盛发期长；为害时间长，转株为害严重，被害症状多；三代发生为害加重。据此提出了防治对策。明确减少越冬虫源、秋收灭茬、科学管水、合理施肥等农业措施的防治作用。提出药剂防治一代二化螟应改一次施药为一次重点，重发区补治、挑治。明确在新的发生情况下，各代的防治对象田、防治适期和防治指标。

In latest 10 years, rice stalk borer population increased quickly. The analysis was performed based on the data of rice stalk borer occurred in Susong county for 30 years. And the result showed that the occurring characteristics of rice stalk borer in recent years are as the following: broad overwinter place and large bases, unidentical growth and more moth peak, long full occurred time, long damage time and serious damage at the 3rd generation. And then, the control strategies are offered as following. Conform the effect of the agriculture strategies such as decreasing the overwinter population, clearing the rice stubble, managing irrigation scientifically, and fertilizing reasonably. Control the 1st generation rice stalk borer using pestcide once in major area, and supplementary or selecting control in the serious area. Conform the control target field, controlling time and controlling index in the new situation.
