Hospodářský význam chrousta Melolontha hippocastani F. v gradačním území LS Strážnice
Opavský, Tomáš
The aim of this work was to assess the presence of the chestnut cockchafer in LS Strážnice, primarily on the Vracov and Bzenec areas. Using the soil probes the etiology and abundance of the grubs in the soil profile were examined. The current population density of the chestnut cockchafer in this area has been compared with historical damage. Based on the evaluation of health status of the seedlings, the damage caused on planting in the Bzenec area from 2013 and 2014 was evaluated financially. In older cultures of the age 5-10 years, the ability to regenerate trees after being infested by grubs was evaluated. The course and the intensity of swarming were evaluated by light traps. Climatic conditions were scanned via usage of meteorological stations. The ovaries of the deceased females were examined by autopsy. Selection of the laying place of the females was analyzed from the historical materials. The results of the work proved that there is an ever-increasing population of Melolontha hippocastani F. in area of LS Strážnice. Economic loss on planting in the Bzenec area in the years 2013-2014 exceeded 2.5 million Czech crowns. At a time when roots are not eat by grubs, slightly damaged pine trees can regenerate. The number of captured imagos in the Vracov area exceeded all quantity recorded in previous years. The first eggs ready for laying appeared on females on May 6, 2015. The selection of the oviposition site of the females was evaluated with the preference of laying in the old stands.

Chroust maďalový (Melolontha hippocastani F.) – hospodářský význam a možnosti eliminace škod v gradačním území LS Strážnice
Opavský, Tomáš
The aim of this work was to evaluate the amount of damage caused by the grubs of forest cockchafer. The damage was assessed in relation to the habitat conditions of the mining and cultivation practices. The pilot plant treatment of Actara 25 WG and Force 1.5 G was evaluated for efficacy against 2nd and 3rd grub instars. A methodical design of aerial intervention to inhibit the forest cockchafer during the 2019 swarming was drawn up. When evaluating the amount of damage, 59,233 pieces of seedlings were checked in 2017. The pilot plant treatment was applied to 4 473 pieces of seedlings and the application was carried out in seven different variants on three districts of the Forestry Administration in Strážnice. The average amount of damage caused by the infestation of forest cockchafer grubs in the Forestry Administration in 2016–2018 is 36%. The Actara 25 WG applied by irrigation was evaluated as the most efficient variant during pilot plant treatment. Based on the vegetation inspection and the extent of the damaged area, an aerial intervention was proposed in two variants to inhibit the forest cockchafer swarming in 2019.

Analysis of Attendance in Czech Ice Hockey Extraliga
Opavský, Tomáš ; Novotný, Jiří (advisor) ; Kuchár, Róbert (referee)
The aim of this Master's thesis is to find, describe and analyse factors influencing the audience demand for Czech ice hockey extraliga matches and on the basis of the observed facts to try to suggest conceivable measures to increase such demand. There are especially mathematical and statistical methods widely applied in the practical part of the thesis. Particularly, arithmetic averages, correlation analyses and various kinds of specific coefficients are used. Average attendances and significance of individual factors are evaluated using the method of comparison, namely its factual, temporal as well as spatial form. The main contribution of this thesis consists mainly in the current mapping of the extraleague club fans' opinions and attitudes through the implementation of the comprehensive on-line survey whose results are contained in individual paragraphs.
