Abstract:[Objectives]  Natural enemies play an important role in regulating pest populations. Understanding and mastering the feeding relationship and transfer and diffusion of natural enemies can provide a basis for quantitative evaluation of the control functions of natural enemies. [Methods]  In this study, the micro-landscape system composed of apple trees (Malus pumila) and Cnidium monnieri (L.) Cuss. is taken as the research object. The main line of the C. monnieri and Celery aphid (Semiaphis heracleid Takahashi) and lady beetle (Harmonia axyridis (Pallas)) were used, to measure the content of rubidium in plants and insects. [Results]  Two approach of laboratory and field sampling are combined by using the rubidium marking method. By measuring the content of rubidium in natural enemies, the effect of planting functional plants on the control of natural enemies in orchards was quantitatively evaluated. [Conclusion]  The rubidium marking technique is an important method to trace the feeding and transfer of natural enemies in agroecosystem.
