不同接蚜方式对烟蚜繁殖效果的影响

Effect of Different Aphid Inoculation Methods on Aphid Reproduction

利用盆栽成株法、漂浮盘育苗法两种繁蚜方法,研究了挑接法、抹接法、碎片法3种接蚜方式对烟蚜繁蚜效果的影响。结果表明：盆栽成株法繁蚜3种接蚜方式繁蚜速度（繁蚜量）表现为抹接法〉碎片法〉挑接法;漂浮盘育苗法繁蚜以碎片法接蚜繁蚜效率最好,其次是挑接法,抹接法效果最差。在相同的繁蚜时间里,采用成株法繁蚜的繁蚜量是漂浮盘育苗法的7.85-18.6倍。

The effects of different aphid Inoculation methods on aphid reproduction were studied with planting of potted plant and floating tray seeding methods. The result showed that ： when potted planting method was used, the velocity （ amount） of aphid reproduction was the highest with picking up method,that of wiping off method was the second,and that of fragment method was the third. When floating tray seeding method was used,the velocity （amount） of aphid reproduction was the highest with fragment method, that of picking up method was the second, and that of wiping off method was the third. During the same time of aphid reproduction, the amount of planting of potted plant was 7. 85 - 18. 6 times more than that of floating tray seeding method.
