Abstract:

The aims are to select the host suitable for Myzus persicae growth and reproduction in Fujian tobacco area, enlarge the reproduction of Myzus persicae and Aphidius gifuensis, and improve the control effect. The eggplant, oilseed rape, white radish, Chinese cabbage, cowpea, ‘Honghuadajinyuan’ and ‘K326’ were used as materials. The parasitism rates of Myzus persicae and Aphidius gifuensis were detected by pot-culture method. The results showed that the number of M. persicae population in Chinese cabbage and oilseed rape was relatively high, the number in Chinese cabbage was respectively 129.07 (2012) and 109.14 (2017) individuals per plant, and the number in oilseed rape was respectively 110.79 (2012), 99.82 (2017) individuals per plant. The number of M. persicae in cowpea was relatively low, which was 0.27 (2012) and 1.23 (2017) individuals per plant, respectively. The number of M. persicae in Chinese cabbage and oilseed rape had no obvious difference. There were differences after infecting A. gifuensis 7 days and 15 days, but the parasitism rate reached more than 98% after infecting A. gifuensis 30 days and the difference was not obvious. Thus, Chinese cabbage and oilseed rape are the suitable hosts for Myzus persicae growth and reproduction in Fujian tobacco area.
