稻纵卷叶螟目前已成为水稻生产的主要害虫之一,各国对其研究也逐步深入。国外在抗性鉴定、抗性育种方面研究得深入扎实,国内在迁飞、测报、生物防治方面成绩突出。早期研究多偏重于生物学特性及地方发生规律,近期研究多集中于生态学特性及综合防治。国内外研究均认为氮肥水平对稻纵卷叶螟种群数量上升和危害加重有直接的密切关系, Rice leafroller has now become one of the major pests of rice production, and various countries have gradually deepened their research. Abroad in the resistance identification, resistance breeding research in-depth solid, the domestic migration, measurement, biological control outstanding achievements. Most of the early studies focused on the biological characteristics and the local occurrence rules. Recently, most studies focused on the ecological characteristics and integrated prevention and treatment. Domestic and foreign studies all believe that the nitrogen level has a direct and close relationship with the increase of the population of the Cnaphalocrocis medinalis and its increased harm,
