| 中文摘要: |
| 载体植物系统（Banker plant system, BPS）通过建立自然天敌的自我维持机制以持续控制田间及保护地害虫。本研究分别以玉米蚜Rhopalosiphum maidis (Fitch)和小麦Triticum aestivum L.作为替代猎物和载体植物，构建龟纹瓢虫Propylaea japonica (Thunberg)载体植物系统防控桃蚜Myzus persicae (Sulzer)，通过正交试验设计优化该载体植物系统中各因子的组合，并对该系统繁殖的龟纹瓢虫对玉米蚜和目标害虫桃蚜的取食选择性进行研究。结果显示，龟纹瓢虫成虫获得量最大的组合是小麦播种后第四天接蚜720头，待蚜虫扩繁5天后，投入龟纹瓢虫初孵幼虫30头。取食选择性试验结果表明小麦载体植物扩繁的龟纹瓢虫对靶标害虫桃蚜具有良好的捕食作用。 |
| 英文摘要: |
| Banker plant system (BPS) is a form of conservation biological control with the goal of sustaining a reproducing population of natural enemies to suppress the pest for a long time. We selected Rhopalosiphum maidis (Fitch) and Triticum aestivum L. as the alternative prey and banker plant for Propylea japonica (Thunberg) establishing banker plant system to against Myzus persicae (Sulzer). Feeding preference experiments and orthogonal array design were conducted to optimize this kind of BPS in the paper. The result showed that the optimal combination for the maximum quantity of P. japonica adult was introducing 720 R. maidis the fourth day after sowing wheat seeds, five days later, introducing 30 newly hatched P. japonica larvae. The feeding preference experiment demonstrated P. japonica had strong preference for M. persicae as well as R. maidis. |
