Biological methods for the control of harmful arthropods based on the promotion and long-term establishment of antagonists have so far been insufficiently used in the cultivation of field crops in Germany. A major obstacle here is mobility and the associated migration of antagonists from the respective target crop. Flower strips represent a possible element for improving the living conditions of antagonists and thus for optimizing the ecosystem service 'pest control'. The overall objective of the HIPSteR project is therefore to harness volatile semiochemicals (Herbivore-Induced Plant Volatiles, HIPVs) to increase the attractiveness of flower strips for antagonists in the sense of an 'attract-and-reward strategy' (A&R strategy). This innovative strategy for the sustainable and biological regulation of harmful arthropods is to be implemented in organic viticulture as a model crop; a later transferability to other field crops is planned. To achieve the project objective, the following partial results are to be developed: (1) A practical, innovative formulation of selected HIPVs by means of microencapsulation allows an application in the field and ensures the release of the HIPVs in sufficient quantity and over a sufficient period of time. (2) Statements can be made about necessary application rates and application intervals of the formulated HIPVs and their attractiveness to selected antagonists. (3) The efficacy of the A&R strategy has been optimized under controlled conditions and is validated in practical vineyards. (4) Vine growers are provided with recommendations for sowing and maintenance of flower strips or companion plants as well as for the application of formulated HIPVs on flower strips and thus for the application of the attract-and-reward strategy in viticulture.
