不同寄主植物繁蚜繁蜂及防治蚜虫效果研究

采用盆栽成株法研究烟叶、大豆、花椰菜、萝卜繁蚜繁蜂效果,然后在烟草及茶叶、柑橘、葡萄放飞蚜茧蜂防治蚜虫,结果表明,批量扩繁蚜茧蜂前期可以萝卜迅速繁蚜后接种烟叶繁蜂,可提高整体繁蜂效率。与空白对照(不放蜂)相比,放飞僵蚜苗防治蚜虫效果较好；与化学防治相比,生物防蚜节约了防治成本,取得了良好的经济效益与社会效益。

Study on reproduction of aphids and bees from different hosts and their control effects on aphids

The effect of aphid propagation in tobacco, soybean, cauliflower and radish was studied by pot growing method, and then aphid cocoon wasps were released in tobacco, tea, citrus and grape to control aphids. The results showed that the early stage of mass propagation of aphid cocoon wasps could quickly reproduce radish, and then inoculate tobacco leaves to reproduce wasps, which could improve the overall bee propagation efficiency. Compared with the blank control (without bees), the effect of flying stiff aphid seedlings on aphid control was better; Compared with chemical control, biological aphid control has saved the control cost and achieved good economic and social benefits.
