Introduction In Europe nature conservation emphasizes protection of remain biodiversity of secondary habitats formed and maintained by agriculture. Although, studies rather examined wildlife of natural habitats, than of cultivated landscape elements (croplands, country roads, roadsides, etc.), but investigation of later is crucial to understanding the system functionality. Orthopterans, known as indicators of habitat structure and natural value, were analysed in a traditional intensively used agricultural landscape to determine how different landscape elements (arable lands and linear habitats) maintain Orthoptera diversity. Materials and Methods Sampling was made along the Sajó and Tisza rivers to determine which habitats can preserve higher diversity compared to semi-natural control sites. In our three-year study (2018-2020), 36 sampling sites of relevant habitats for orthopterans were sampled with sweep-netting and transect counts. Results In the poorly known area, 29 Orthoptera species including protected Gampsocleis glabra (Her.), Acrida ungarica (Her.), and Celes variabilis (Pall.) were caught. Four different Orthoptera assemblages were distinguished. Intensively cultivated fields (maize, sunflower, and wheat fields) showed lower diversity compared to less intensively cultivated and/or disturbed lucerne and red clover fields, roadsides, country roads, and semi-natural sites (hayfields, pastures). The diversity and composition were primarily affected by intensity of land use and secondarily by the culture. Lucerne and red clover fields with grass-like vegetation structure preserved a significant part of the original (natural) fauna, while crop rotation also increased diversity. Conclusions During the study we identified habitat types effectively preserve insect diversity, even under a long-term intensive land use regime. Landscape management and cultivation planning regarding these findings can help sustainable agriculture and maintain of higher diversity.
