Attractive planting of species of potentially expanding bee pastures for bees
ŠEBESTA, Tomáš
This diploma thesis entitled "Attractiveness of Planting Species with a Potential to Extend Bee Forage for Bees" discusses pollen and nectar plants planted in the Brník municipality in the Central Bohemian Region. The thesis consists of two parts. The theoretical part describes honeybees, bee plants and their pollen- and nectar production ability as well as bee forage from early spring until late autumn so as to reflect the needs of pollinators as best as possible. The practical part uses pollen analysis to microscopically analyse the representation of pollen grains of plants in the honey produced by local bee colonies. Pollen analyses of honey from own bee colonies are compared with that from bee colonies belonging to neighbouring beekeepers.

Vyšetření včelstev na nosematózu
BRABENEC, Jiří
Nosematosis belongs to the intestinal disease of bees, which is widely spread both in the world and in the Czech Republic. It is caused by Nosema apis and Nosema ceranae. The aim of this diploma thesis was to evaluate the occurrence of the Nosema dispute in the territory of ČSV Bystřice, to describe species variability and to assess the effect of the season on the occurrence of Nosema apis and Nosema ceranae. To detect infection of colonies, 5 bees from selected hives were examined under the microscope. In positive specimens on nosematosis, the species of Nosema spore was molecularly examined. In total, 93 samples from 15 breeders were examined. Samples were taken in the spring and summer of 2017. The sampling took place both for malachists and for farmers with more than 150 bee colonies. During the summer sampling more positive bees were found than in spring sampling. Beekeepers were further assessed by the number of hives. Following the analysis of the samples obtained using the PCR method, Nosema ceranae disputes were present in the vast majority of colonies.

Parasitic bacteria Arsenophonus in honeybee and its parasite Varroa destructor
Hejdánková, Sylvie ; Hubert, Jan (advisor) ; Smrž, Jaroslav (referee)
Arsenophonus is vertically and horizontally transmitted parasitic bacteria and strengthens its transfer through phenomenon called son killing. Arsenophonus has been detected in the arthropod hosts, insects, ticks and the garden spider Araneus diadematus. The aim of this study is detection parasitic bacteria Arsenophonus in honeybees and its parasite Varroa destructor. We find out that bacteria Arsenophonus is present in both hosts and it is identified as Arsenophonus nasoniae. Detection of bacteria Arsenophonus is discovered for the first time in Varroa destructor mites. We proved that the frequency of bacteria Arsenophonus in mites Varroa destructor is significantly higher than in honeybees. This study shows that the mite Varroa destructor could act as a vector for transmission parasitic bacteria Arsenophonus among honeybees. Results of this study could lead to the future application of Arsenophonus as a biological control for the mite Varroa destructor.

Paenibacillus larave destroying the honeybees (Apis mellifera) population
Haltufová, Kristýna ; Hubert, Jan (advisor) ; Kamler, Martin (referee)
Paenibacillus larvae is Gram-positive, spore-forming, rod-shaped bacteria. This pathogen threatens one of the most considerable worldwide pollinators - the honeybee (Apis mellifera). It is causative agent of bee disease called American foulbrood. Although it affects only bee larvae, preferably on the first day of its live, it is highly contagious and could quickly destroy whole bee colony. Adult bees are not susceptible to infection, however due to huge spores resilient of P. larvae, they perform the role of main disease vector. Also the careless beekeepers make it easier to spread. Bee diseases are enquired by state veterinary administration, because honeybee is classified as a livestock. If disease evolves to clinic phase, infected bees and hive with all tools must be burned. American foulbrood is one of the most deleterious bee diseases. This bachelor thesis discuss about problems of whole disease and it is focused on the interactions between bacteria Paenibacillus larvae, hymenoptera insect honeybee and human factor presented by beekeepers, state veterinary administration and corresponding laws. Key words: Paenibacillus larvae, American Foulbrood, entomopathogenic bacteria, Apis mellifera, honeybee

Meaning and contemporary situation in beekeeping
TUPÁ, Kateřina
This thesis is concerned by importance and current situation in breeding of bees. At first, thesis briefly describes characteristics of Honeybee (Apis mellifera) and its life cycle. At second, thesis summarizes information about ambitiousness of human work dedicated to breeding of a bee and manipulation with hive, which protective equipment is needed. At third, thesis points out the problematic caused by adverse effects like pests, diseases or mankind. Last but not least thesis deals with quality and production of bee products and current situation of beekeeping in the Czech Republic. Beekeeping is one of the oldest branches of human activity and in peoples' free time its importance is not small. Moreover, beekeeping has very important position in agriculture as a source for pollination of insect-pollinated and cross-pollinated plants, where it helps to increase the yields. Next, it has great importance in the branch of foods, mostly thanks to the production of honey. All of the bee products are highly prized in the pharmaceutical, healthcare and glass industry, where they are parts of nourishing and moisturizing preparations, medicaments and firming cements. Quality of hives is given by the experience of beekeeper and the possibility of financial support by grants assigned by Ministry of Agriculture of the Czech Republic. The objective of the thesis is to point out the importance of Honeybee in our landscape and to highlight the significance and quality of bee products. The researches show that the beekeeping is ib the Czech Republic on very high level, but there is lack of beekeepers.

Important plants in terms of pollen for bee-keeping in the spring and early summer in the northern area of the landscape Blanský les
ZÍDKOVÁ, Michaela
Bachelor work dealt with determination of important plants for bee-keeping from pollen loads and the importance of pollen in honeybee nourishment. Pollen loads were collected from one honeybee colony, which stands to the south from the village of Dobčice in Blanský les Protected Landscape Area. Natural reservations of Chrášťanský vrch and Vysoká Běta are in the distance of flying range from the colony. According to the pollen grains were detected taxons of Blanský les Protected Landscape Area?s flora in native preparates and estimated its importance from the point of view of honeybee nourishment in the stated region. The attention was given to the structure of vegetation in honeybee colony surroundings and the occurrence of important biotopes of pollen plants.

Function of honey-bee (Apis mellifera) in see industry of field crops.
PŠENIČKOVÁ, Zuzana
In this dissertation I am trying to point out the importance of the honeybee in the pollination of plants and the connection between the plant and the honeybee. The honeybee is essential and indispensable part of agricultural production that increase in the hectare production. It is also importat in forests, fields and in orchards. In the introduction there is a telling about bee colony and alternative ways of pollinate. In this dissertation I outline economic and ecological features of beekeeping and problems that beekeepers have to solve, some grants from the European Union that help to our beekeepers. In conclusion there are described some problems and different opinions for geneticaly modified plants and their influence for the honeybee.

Bioindication of man effect on environmental pollution by chemical pollutants (heavy metals) with the use of bees and their products (bee honey)
KOS, Václav
The main objective of my work was to evaluate if it is possible to use the honey bee - Apis mellifera as a bioindicator of the environmental contamination by heavy metals. Two areas were being compared. The first one was more affected by emission (The Capital city of Prague) and the second one was less hit by emission (The Highlands). During the course of three years five samples of bee honey were taken from each area. The analysis was made to show how much cadmium, lead and mercury the samples contained. In most samples higher concentration of these chemicals were dealt out in honey taken from the more polluted area. Although not all the concentrations of heavy metals in honey reflect the emission burden of the examined areas. It would be necessary to take samples from a larger number of areas in order to confirm the conclusion that bee honey is a suitable bioindicator of the environmental contamination by heavy metals.
