| 摘 要： | 在恒温条件下用新鲜烟叶饲养斜纹夜蛾，得到危害烟草的斜纹夜蛾各虫态的发育历期，用直线回归法求得斜纹夜蛾各虫态的发育起点温度和有效积温，为烟草斜纹夜蛾的预测预报提供了基础数据。根据所得数据和云南主要烟区的月平均温度推算得到昆明、楚雄、大理1年发生3～4代，玉溪、宜良4～5代，宾川、永仁5～6代。

| Abstract: | In this research the duration of Prodenia litura Fabricus's every developmental period was obtained by feeding it with fresh tabacco leaves;The developmental zero temperature and effective accumulated temperature of Prodenia litura through line-regression method were obtained at difterent development periods. Based on these data and the average monthly temperature in main tobacco districts in Yunnan, a conclusion was got that each year there are 3～4 generations of Prodenia litura occured in Kunming, chuxiong and Dal, 4～5 generations in Yuxi and Yiliang, 5～6 generations in Binchuan and Yongren. This research provided basic data for the forecast of tabacco Prodenia litura. |
