Abstract Conservation measures such as those under the European Green Deal aim to counteract biodiversity loss by increasing share of organic farming and reducing pesticide use, well proportion semi-natural habitats (SNH) in agricultural landscapes. Given large environmental impacts agriculture, it is important thoroughly understand effects on organisms provide evidence-based effective implications for conservation. In this study, we analysed how vineyard management, reduction, landscape composition affect Orthoptera densities species composition. Therefore, sampled herb- vine-dwelling orthopterans a paired design classic fungus-resistant grape (FRG) varieties conventionally organically managed vineyards along heterogeneity gradient. Here, FRG allowed us study effect 44% reduced applications real-world conditions. Total herb-dwelling did not differ between conventional vineyards, but were 2.9 times higher management. contrast, total Orthoptera, mainly driven dominant Phaneroptera falcata , similar tended be 1.4 grapes Furthermore, management system SNH radius 500 m surrounding influenced
