    烟蚜茧蜂规模繁殖中烟蚜越冬寄主筛选

    Winter Host Selection of Myzus persicae for Mass Rearing of Aphidius gifuensis

    • 摘要: 烟蚜越冬种群保育对保障烟蚜茧蜂规模繁殖具有十分重要的意义。通过接种烟蚜与烟蚜茧蜂,对玉溪地区8种不同寄主植物上烟蚜的增长数量、烟蚜茧蜂寄生烟蚜后形成僵蚜的体重进行了比较。结果表明,接种后,油菜、白萝卜、红萝卜上烟蚜数量以及僵蚜体重均可达到烟蚜茧蜂繁殖技术指标要求,可作为烟蚜茧蜂规模化繁殖体系中烟蚜的理想越冬寄主。

       

      Abstract: Maintenance of over-wintering population of Myzus persicae plays a vital role in mass rearing of Aphidius gifuensis. Numbers of M. persicae and weight of aphid mummies of A. gifuensis on 8 host plants in Yuxi of Yunnan Province were examined through inoculation of aphids and adult A.gifuensis respectively. The results showed that numbers of M. persicae and weight of mummified aphids of A. gifuensis were satisfactory feeding on oilseed rape, white radish and red radish, suggesting these three crops could be the suitable winter hosts of M. persicae for mass rearing of A. gifuensis.
