摘　　要：为有效防治烟青虫,依据湖南省各烟草测报点多年系统调查的数据,进行了烟青虫发生规律及预测预报研究。结果表明,烟青虫理论发生代数与实际发生代数一致;各地第1代蛾量均多于第2和第3代,一般始蛾早、始发蛾量多的年份预示当年烟青虫发生量偏多;与烟青虫预测预报相关的主要因子有引诱微环境、天敌、冰冻、诱集植物等。In order to effectively control Heliothis assulta Guenée,its regularity of occurrence and forecasting were studied on the basis of years＇ records collected from each monitoring point in tobacco planting areas in Hunan.The results showed that the actual number of generations of Heliothis assulta Guenée agreed with that of predicted ones;the population of the first generation was always larger than that of the following generations.Generally,more moths＇ emerged earlier than usual foreshadows its prevalence in that year;the major factors relevant to forecast were microenvironment of attraction,natural enemies,frost,attractive plant,etc.
