Permakulturní praktiky a možnosti jejich využití
Žáková, Erika
In the first part of the Bachelor thesis, the concept of permaculture is defined, as well as its history and then, there is a description of permaculture principles and practices which can be used in both rural and city environment. In the second part, the author compares the differences in agrotechnical approach and revenues in permaculture and intensive agriculture. The point was to capture and objectively review the advantages and disa-dvantages of these types of agriculture and determine the limit factor. Within the field investigation, a visit to a natural garden, which belongs to a family house, took place. The result is a plan creation, foto documentation, a description of cultivated crops and practices used in this garden.

The thesis is formed by two parts. The first part, theoretical, contains a research on the municipality, the municipality budget, especially its revenue part, and the main element was Zákon č. 338/1992, Zákon České národní rady o dani z nemovitých věcí in its valid wording from 1.1.2016. The practical part is focused on research of the law in years 2005 to 2016, on identifying changes in the law in these years and the financial impact they had on the municipality Tišnov and its budget. In the next part is the information generalized to municipalities of similar size as Tišnov. The discussion is formed by opinions and possible metods of mak-ing the real estate tax more effective from different authors and these are summa-rized and compared in the conclusion.

Use of macroorganisms and microorganisms in biological control of whiteflies
ŽÁKOVÁ, Erika
Whitefly is one of the most important greenhouse pests that can cause significant damage to crops. Whitefly suck juice from plants and produce honeydew which is sugar source for saprotrophic fungi called sooty mold. Fungi cover the leaves and reduce the leaf assimilation area. The most serious harm of whiteflies is attributed to transfer of many plant viruses. The most serious whiteflies commonly found in the greenhouses are Trialeurodes vaporariorum and Bemisia tabaci. For the control of whitefly populations, the seasonal inoculum strategy of biological control is used, with the aim of immediately overlapping the pest with the right choice of natural enemies. Biological control contributes to the control of whiteflies in the greenhouse, specifically the use of natural enemies based on macro-organisms and microorganisms. The macroorganisms include parasitoids and predators. The most important commercially used whitefly parasitoids are Encarsia formosa, Eretmocerus eremicus and E. mundus. Predators used in biological control against whitely is the predatory bug Macrolophus caliginosus, the predatory ladybug Delphastus catalinae and the predatory mite Amlyseius swirskii. Parasitic wasps are narrowly specialized in both whitefly species, while predators are polyphagous species that can feed on more pest species. Bioproducts based on entomopathogenic fungi are also used against whiteflies in the abroad. The most important species are Aschersonia aleyrodis, Isaria fumosorosea, Beauveria bassiana and Lecanicillim muscarium. For the effective use of these bioagents, it is important to have knowledges not only about pest, but also about interaction among pest - natural enemy - host plant. So it is important to perform quality monitoring of whiteflies in the greenhouse to make the use of natural enemies profitable.
