Vondřich, Vladimír ; Šrůtka, Petr (advisor) ; Nakládal, Oto (referee)
This thesis aims to analyze actual state of the nun moth (Lymantria monacha L.) in the Brdy region in the year 2015. The main objective was to determine its population density. For the research several sites were selected in which three monitoring methods were used: adhesive tree bands, dropping method and pheromone-baited traps. The results revealed that the nun moth only occurs in the forest in minimal numbers. Another objective was to evaluate colour forms of moths and determine connection between colour forms of caterpillars and moths. For the lack of captured caterpillars no results were acquired. The majority of moths caught on pheromone-baited traps had gray colouring and relatively small number of moths (21%) had basic (white) colouring.
