Marketing reasearch cosmeticals for animals
Bartoňová, Klára ; Mgr.Jan Ríha,Ph.D. (referee) ; Souralová Popelková, Miriam (advisor)
This Bachelor's Thesis deals with marketing research of the market with cosmetics for animals. In the practical part of the thesis a survey of the market was carried out. For this purpose a questionnaire was developed and sent out to owners of domestic animals. The questionnaire was then verbally evaluated and the crucial results were put into a graph. The theoretical part focuses on description of the most used veterinary preparations, their specifics, the most important chemicals contained in them, sensory evaluation of products, potential toxicity and undesirable effects on an animal. The valid legislation requirements applying to veterinary preparations within Czech Republic are mentioned in the conclusion. To specify individual products correctly I contacted a number of distributors concerned with the issue.

Rezistence škůdců řepky k vybraným účinným látkám insekticidů
Hajda, Tomáš
Resistence population of pollen beattle on selected locations of Moravia and Silesia were observed during the 2017. Beattles were taked off in the field during spring and their sensitivity to insecticides active substances indoxacarb, chlorpyrifos, thiacloprid, tau-fluvalinate, cypermethrin and lambda-cyhalothrin were tested in laboratory. Tested using methods of IRAC – 11, 21, 25 and 27. Mortality of beattles at various concentrations of active substances was evaluated after 24 hours. Levels of resistance were changed for individual location.

Voltammetric determination of pesticides using meniscus modified silver solid amalgam electrode
Gajdár, Július ; Fischer, Jan (advisor) ; Dejmková, Hana (referee)
The aim of this bachelor thesis is to find the optimal conditions for voltammetric determination of pesticides cypermethrin, deltamethrin and difenzoquat on meniscus modified silver solid amalgam electrode using differential pulse voltammetry. Conditions under which cypermethrin and deltamethrin could be determinated were found in previously published works. These conditions were reproduced. Substances were studied in methanol and dimethylformamide solutions. The optimal conditions for determination of these two substances were not found. Voltammetric behaviour of difenzoquat was studied in different pH using Britton-Robinson buffer. The optimal pH 11 was chosen. The reproducibility of measurement was studied at concentration 1·10-4 mol·l-1 , peak was stable (RSD = 3%). Sharp maxima were found at high concentrations of analyte, addition of gelatine led to one well- defined peak. Peak potencial was - 1,4 V. Calibration dependences were measured at concentrations 2·10-7 mol·l-1 - 1·10-4 mol·l-1 . Limit of determination was 6,1·10-7 mol·l-1 . Linear dynamic range of this method was found between concentrations 6,1·10-7 - 2·10-5 mol·l-1 . Difenzoquat was determined in model samples of drinking and river water. Limits of detemination were achieved at concentrations 3,4·10-7 mol·l-1 in drinking water and...

Rezistence blýskáčka řepkového (Meligethes aeneus, Fabr. 1775) k pesticidům na vybraných lokalitách jižní Moravy
Kubátová, Kateřina
My thesis is devoted to the resistance of pollen beetle (Meligethes aeneus, son. Brassicogethes aeneus Fabricius, 1775) to pesticides in selected localities in southern Moravia. Collecting adults was performed in the spring of 2013 by tapped into polyethylene bags. Adults are collected from the stands of oilseed rape, mustard and poppy. Tests were performed on the basis of the methodology of Insecticide Resistance Action Committee number 011, 021, 025. In total, we tested the pollen population from 18 locations. For testing, we used the following chemical substances: Biscaya 240 OD, cypermethrin, lambda-cyhalothrin, tau-fluvalinate, etofenprox, chlorpyrifos(ethyl). We evaluated 100% of the registered dose of pesticides after 24 hours. From the results of the individual populations, we found large differences in resistance to chemicals.
