摘要
随着陕西烟草种植面积不断扩大,烟蚜成为严重影响烟草生产的问题之一。调查发现,陕西烟田蚜虫主要天敌昆虫14种,分布于4个目6个不同科属,其中优势种为异色瓢虫、大灰食蚜蝇和烟蚜茧蜂,可在其中进一步挑选防治效果好、成本低、操作性强的天敌昆虫。
The tobacco planting area expands unceasingly in Shaanxi,Myzus persicae(Sulzer) is an important problem to influence the tobacco production. The research on species of aphids natural enemy insects in Shaanxi,the result shows that there are14 species of aphids natural enemy insects,distributed in six different genera.
