Vineyards are hotspots of biodiversity due to their heat-favorable location and their richness of plant species and structures. Climate change-induced new species often occur first in these crops. At the same time, these are the crops with the highest pesticide applications. The challenge for modern plant protection in wine growing is to create a balance between crop management, fertilization, and plant protection on the one hand and nature and resource conservation on the other. In this project, in addition to the influence of different forms of cultivation and near-natural habitat structures in the vicinity of the vineyards, we will evaluate the effect of reduced plant protection through the cultivation of fungus-resistant grape varieties. Both classical methods of insect taxonomy and metabarcoding will be applied. Our results will provide information on the importance of local management and landscape structure for biodiversity in viticulture, especially for the insect order Hymenoptera, as a basis for long-term monitoring.
