烟蚜茧蜂在不同寄主植物上的扩繁效果及防治蚜虫效果研究

Study on Propagation Effect of Aphidius gifuensis on Different Host Plants and Its Control Effect on Aphids

试验采用盆栽成株法研究烟叶、大豆、花椰菜、萝卜繁蚜繁蜂效果,并在烟叶、茶叶、柑橘、葡萄田调查大面积释放烟蚜茧蜂对蚜虫的防治效果。结果表明:批量扩繁烟蚜茧蜂时,可采用萝卜作为寄主,提高整体繁蜂效率;与不放蜂对照区相比,大面积释放烟蚜茧蜂防治蚜虫效果较好,且经济效益、生态效益与社会效益良好。

The propagation effects of aphids and Aphidius gifuensis in tobacco,soybean,cauliflower and radish were studied by pot growing method,and the control effect of releasing Aphidius gifuensis in large area on aphids was investigated in tobacco,tea,citrus and grape fields.The results showed that radish could be used as host to rapidly propagate aphids and Aphidius gifuensis,and the overall propagation efficiency could be improved.Compared with the control area without Aphidius gifuensis release,the control effect of large-scale release of Aphidius gifuensis against aphids was better,and the economic,ecological and social benefits were good.
