我国稻田大螟发生规律与防治技术研究进展

自20世纪中叶以来，在长江中下游局部地区，稻田大螟的发生与危害呈逐年上升的趋势，并逐渐由常发性的次要害虫发展成为目前水稻上的主要害虫之一，在部分稻作田块的危害已接近或超过其他害虫。该文基于近几年国内有关稻田大螟发生与防治情况，就其种群变化、危害程度、发生规律、生物学特性、防治和测报技术等方面的研究进展进行了综述。 

Research Progress on Occurrence Rules and Control Technique of Sesamia inferens Walker in Rice Field in China

Since medium term of 20th century，occurrence and damages of Sesamia inferens Walker were increasing year by year in the middle and lower reaches of Yangtze River in China.And Sesamia inferens Walker had become one of major pest in rice field，occurrence and damages of Sesamia inferens Walker pest were likely to match or exceed other insect pest in part of rice field.Population dynamics，harmful levels，occurrence regularity，biological characteristics，control and forecast technique，and so on were summarized based on occurrence and control situation in recent years.
