箭头线段粗细和端点大小指代各营养级关系强弱;储蓄植物提供花粉或替代猎物的寄主,直接或间接为捕食性天敌提供有限的替代食物,从而维持和增殖其种群;在目标害虫出现时,天敌控制其种群,从而减轻其对目标作物的危害,达到生物防治目标
Fig. 1. A model of banker plant system of predators for biological control of arthropod pests
Level of interaction among trophic levels shown by thickness of arrows and size of circular endpoints. Banker plant provides nutrition, such as pollen, or host for alternative prey, to support the predatory natural enemy ahead of the preys’ arrival. When the target prey is destructive to crop, the predator could control them to some extent
