The stick tea thrip (Priesner) (Thysanoptera: Thripidae) is a destructive pest in tea plantations in south and southwest China. To control this pest, a non-crop banker plant system was developed using a polyphagous predator (Poppius) (Heteroptera: Anthocoridae) with the black bean aphid (Scopoli) (Hemiptera: Aphididae) as an alternative prey and the faba bean as the banker plant to support the predator in targeting the pest. The fitness of on tea plants and faba bean was evaluated to determine its host specificity. Moreover, the control efficacy of the banker plant system on on tea plants was tested in the laboratory and compared with that of direct release of . The experiments showed that faba bean was an excellent non-crop host for because, while the aphid population increased quickly on faba bean, it could only survive for up to 9 days on tea plants. Compared with direct release of , lower densities of pest were observed when introducing the banker plant system. Our results indicate that this banker plant system has the potential to be implemented in the field to improve the control of the pest thrips.
茶棍蓟马（普里斯纳）（缨翅目：蓟马科）是中国南方和西南部茶园中的一种毁灭性害虫。为了防治这种害虫，开发了一种非作物替代植物系统，使用多食性捕食者（波皮乌斯）（半翅目：花蝽科），以黑豆蚜（斯科波利）（半翅目：蚜科）作为替代猎物，并以蚕豆作为替代植物来支持捕食者捕食害虫。评估了该捕食者在茶树和蚕豆上的适合度，以确定其寄主专一性。此外，在实验室中测试了替代植物系统对茶树上茶棍蓟马的防治效果，并与直接释放捕食者的效果进行了比较。实验表明，蚕豆是该捕食者优良的非作物寄主，因为虽然蚜虫种群在蚕豆上迅速增加，但在茶树上最多只能存活9天。与直接释放捕食者相比，引入替代植物系统时观察到害虫密度较低。我们的结果表明，这种替代植物系统有可能在田间实施，以改善对害虫蓟马的防治。
