摘　　要：[目的]更好地利用烟蚜茧蜂防治烟蚜,进一步明确不同散放次数对烟蚜的防治效果。[方法]从不同烟蚜茧蜂散放次数对烟蚜的控制、防治效果以及烟叶田间表现等方面进行研究。[结果]不同散放次数对烟蚜的控制效果表明,多次散放及提早散放烟蚜茧蜂僵蚜,有利于茧蜂早期繁殖,对烟蚜种群控制相对较好。在药剂防治与放蜂防治烟蚜的效果对比中,蚜茧蜂对烟蚜在长期作用和防治稳定性方面对烟蚜有明显效果,且在放蜂总量一定条件下,以3次放蜂处理防效表现最好,稳定性强,田间调查表明,烟叶破损率和烤后经济收益表现均以3次放蜂处理最佳。[结论]烟蚜茧蜂作为重要的烟叶绿色防控手段,在确保烟叶品质和促进烟农增收方面具有良好的推动作用。[Objective] To make better use of Aphidius gifuensis to control Myzus persicae, and to further clarify the control effect of different release times on Myzus persicae.[Method]The control, control effect and tobacco leaf field performance of Myzus persicae were studied by different dispersal times of Aphidius gifuensis.[Result]The control effect of different times of dispersal on the tobacco aphid showed that multiple and early dispersal of the aphid were beneficial to the early reproduction of the cocoon bee, and the control of the population of the tobacco aphid was relatively good.In the control of tobacco aphids by pesticides and releasing bees, the long-term effect and stability of aphid on tobacco aphids were obvious, and the control effect of three releasing bees was the best under certain total amount of releasing bees.[Conclusion]Aphid wasp, as an important means of tobacco green control, played a good role in ensuring the quality of tobacco leaves and promoting the income of tobacco farmers.
