摘要： 为了解决粤北烟区烟草上主要害虫对烟草的危害问题，以烟草上烟蚜、烟青虫和斜纹夜蛾为试验材料，采用田间系统调查方法对上述主要害虫及其天敌种群进行了研究。通过3年连续田间调查，确定广东南雄烟区主要害虫为烟蚜、烟青虫和斜纹夜蛾；烟蚜种群发生规律呈现双峰型，烟田烟青虫成虫和幼虫1年有多个发生峰值，斜纹夜蛾幼虫在烟叶生产季节有2个发生高峰期。烟田优势寄生性天敌有寄生于烟蚜的烟蚜茧蜂和寄生于烟青虫幼虫的棉铃虫齿唇姬蜂及寄生于斜纹夜蛾的侧沟茧蜂；优势捕食性天敌主要有龟纹瓢虫、七星瓢虫、中华草蛉、红彩真猎蝽、烟盲蝽、狭带食蚜蝇和青翅隐翅虫等，其中红彩真猎蝽不仅捕食烟蚜，还捕食烟青虫和斜纹夜蛾幼虫，具有较好的研究价值和应用前景。

Abstract: In order to solve the problem of pests damage on tobacco in northern Guangdong tobacco area, with Myzus persicae, Heliothis assulta and Spodoptera litura as experiment materials, field experiment was conducted for investigating the population system of the main insect pests and their natural enemies. The results showed that Myzus persicae, Heliothis assulta and Spodoptera litura were the major pests in Nanxiong tobacco field. M. persicae and S. litura each has two population peaks each year, while several peaks occurred each year for H. assulta. The major predatory natural enemies in northern Guangdong were Coccinella septempunctata, Cyrtopeltis tenuis, Propylaea japonica, Chrysopa sinica, Harpactor fuscipes and Paederus fuscipes, while the main parasitoids were Aphidius gifuensis, Campoletis chlorideae and Microplitis prodeniae. H. fuscipes was a potential biological control agent for M. persicae, H. assulta and S. litura in tobacco fields.
