中文摘要：
本文总结了我国1950—2013年粘虫Mythimna separata（Walker）发生、防治和损失概况，揭示了60余年中我国粘虫种群数量动态的演化规律。（1）南方地区越冬代种群发生年代间有波动，江淮1代发生区为害减轻，东北、华北、黄淮、西北和西南等2、3代发生区发生加重。（2）2代粘虫为发生最为广泛的1代，1995年以来粘虫主要危害作物已由小麦变为玉米。（3）寄主作物种植面积对种群数量总体变动起重要作用，气候条件影响年度间和区域间的种群波动和变化，农田生境影响小区域的发生危害程度。
英文摘要： The occurrence, management, and economic impact of the armyworm, Mythimna separata (Walker), inChinawas reviewed based on data from field surveys and poplar branch and light trap catches from 1950 to 2013. Several key characteristics of armyworm population dynamics are as follows: (1) The fluctuation of the overwintering generation of armyworms was slightly different in southern China, the population size of the first generation declined in Jianghuai region of central China, but the damage caused by the second and third generation have been progressively greater in recent years; (2) The most extensive spatial distribution of the second generation was seen in the Huanghuai region, northern, northeastern, southwestern and northwestern China, and since 1995, the major crop affected by armyworms has been wheat rather than corn. (3) The most important factor affecting armyworm population dynamics is the planting area of cereal crops, although annual and regional population fluctuations are determined by changing climate, the extent of crop damage depends on the local farm habitat.
