南方春烟区应用烟芽茧蜂防治烟蚜主要技术障碍及对策

Main Technical Obstacles and Countermeasures of Controlling Tobacco Aphid by Aphidius gifuensis in Spring Tobacco Area in Southern China

南方春烟区在烟叶种植制度、地理气候等方面存在许多特殊性,针对在烟蚜茧蜂繁育过程中存在的大棚内温湿度不协调等特殊情况,通过改造繁蜂大棚内部结构、改变寄主的培育方式、改善大棚内温湿度环境、调整接蚜时间等措施,能有效改善烟蚜和烟蚜茧蜂的繁殖效率,提高烟蚜的生物防治效果。

There existing particularityin tobacco cropping system, geographyand climate of spring tobacco area insouthern China, in view of temperatureand humidity incoordination and otherspecial circumstances in greenhouse inAphidius gifuensis breeding process, byreconstructing the inner structure ofgreenhouses, changing breeding mannerof host, improving the temperature andhumidity in greenhouse, adjusting inocu-lation time of aphid, the tobacco aphidand Aphidius gifuensis reproductive ef-ficiency were effectively improved,andthe biological control effect of tobaccoaphid increased.
