摘  要：
斜纹夜蛾是我国子莲的主要害虫之一,每年对子莲的生产造成严重损失。本研究通过利用3种性诱剂诱集斜纹夜蛾雄虫,更精细的研究其发生规律,并筛选出高效的性诱剂产品。结果显示:斜纹夜蛾在子莲田内,发生始于5月下旬之前,第一次调查已有422只雄虫,盛发期为7~8月份,7月中下旬和8月中旬是盛发期内2个易爆发期,10月下旬下降到低点。NK处理斜纹夜蛾性诱剂诱杀数量最多,ZJ处理的次之。NK处理斜纹夜蛾性诱剂在子莲斜纹夜蛾的精准预报预测和无害化生产中将发挥更积极的作用。

摘  要：
The oriental leaf-worm moth Spodoptera litura(Fabricius, 1775) is one of the main pests in the field of seed lotus, causing enormous economic loss for seed-lotus production every year. The present study aimed to uncover the more specific occurrence regularity of S. litura by three using sex pheromones, and screening the high-performance sex pheromone. The field trial results showed that the initial occurrence of S. litura was before late May? the adults occurred mainly from July to August? there were two peaks in middle and late July and middle August, respectively? the population size was toward to lowest level in late October. Also, the sex pheromone from New Con Inc., Ningbo had the most trapping amounts of S. litura. The sex pheromone of Pherobio Technology Co., Ltd. had secondary trapping effects. So, the sex pheromone from New Con Inc., Ningbo could be applied to forecast the occurrence of S. litura and the innocuous production of seed lotus.
