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。 Since the middle of the 20th century, the occurrence and harm of Sesamia inferers in the middle and lower reaches of the Yangtze River have been increasing year by year, and gradually developed from the major secondary pests to become one of the major pests on rice. The damage done to fields is close to or over other pests. In this paper, based on the occurrence and control of Sesamia inferens in China in recent years, the progress of researches on the population changes, the degree of harm, the occurrence rules, the biological characteristics, the prevention and the measurement techniques and so on are summarized.
