摘要
[目的]筛选适宜的繁蜂技术和方法。[方法]采用烤烟漂浮苗、成株、假植苗3种方法繁殖烟蚜茧蜂，并对繁蜂效果进行分析。[结果]漂浮苗繁蜂成本较低，周期短，但是病害发生较严重；成株繁蜂量较大，但是周期长，成本也较高；假植苗繁蜂效果较好，成本较低。[结论]试验结果为毕节选择适宜的繁蜂方法提供了理论依据和技术支撑。
Abstract
Objective] To screen the appropriate propagation technology and method.[Method] Aphidius gifuensis Ashmead was propagated by flue-cured tobacco floating seedlings, adult plants, and heeled-in seedlings.The propagation effects of A.gifuensis were analyzed.[ Result] Floating seedlings had relatively low cost and short cycle of propagation , but the disease occurrence was relatively serious .The adult plants could propagate a large amount of A.gifuensis, but needed long cycle and high cost.Heeled-in seedlings showed relatively good propagation effects and relatively low cost.[ Conclusion] The research results provide theoretical basis and technology support for the selection of appropriate propagation method of A.gifuensis in Bijie.
