| dc.description.abstract-translated | This thesis capitalises on data on non-target Macrolepidopteran moths captured by a crop pest monitoring system, operated by the Czech Phytosanitary Administration. The monitoring system uses 21 Minnesota light traps, distributed amidst intensive farmlands of the Czech Republic, and records abundance of 7 species of quarantine pests. In this thesis, I processed and analysed all non-target species (total: 704), captured during three years in 274 559 individuals. The data were used to study the influence of landscape determinants on diversity, abundance and community composition of the moths. For species richness, abundance, as well as community composition, large landscape scales (1 km radius circles) were more important than local scale factors (e.g., habitat diversity within 100 m radius circle). Additionally, regionally common land covers, such as percentage area of woodlands, were more important than regionally rare land covers. Last but not least, I demonstrated the positive effect of crop diversity on moths community composition. | eng |
