摘要
烟蚜茧蜂是烟蚜的优势寄生性天敌,对烟蚜具有较好的控制作用。通过烟草漂浮育苗繁育烟蚜茧蜂防治烟蚜技术已日趋成熟并在云南烟草上得到大规模应用。该项生物防治措施的推广将是实现农业生产大幅度降低化学农药使用量的重要途径。文章对影响该技术各环节的因素进行了分析探讨,提出优化烟草漂浮育苗繁育烟蚜茧蜂效果的措施和对策,建议系统研究制约烟草漂浮育苗繁育烟蚜茧蜂的技术瓶颈,探索产业化途径,为烟蚜茧蜂更广泛的应用提供依据和技术支撑。
Aphidus gifuensis is a domipant natural enemy of Myzus persicae playing an important role in controlling M. persicae. Breeding A. gifuensis by tobacco floating-seedling system has been developed, and has been applied in Yunnan province in a large scale, which suggested that such a way could be important in reducing the chemical pesti- cides consumption. In this paper, factors which affected the production of A. gifuensis in the tobacco seedling float- ing system were analyzed, and optimizations were proposed. Several technical bottlenecks were suggested to be fur- ther studied for exploring the industrial production and furthermore to encourage a broader range of applications.
