Scent glands of true bugs (Heteroptera) and their pattern in micropterous bed bug Cimex lectularius (Cimicidae)
Wiesnerová, Markéta ; Vilímová, Jitka (advisor) ; Kment, Petr (referee)
Chemical communication is considered to be very common type of communication within the insects. Taxon true bugs, the suborder Heteroptera (Insecta: Hemiptera) is well known concerning this type of communication. It is based on a secretion of glands from which the most important are dorsoabdominal scent glands (DAGs) of nymphs and metathoracic scent glands (MTGs) of adults. The present study includes a summary of the knowledge about heteropteran scent glands, including the glands in micropterous bed bug, Cimex lectularius (Linnaeus, 1758) (Cimicidae). Also information about chemical composition and function of the secretion is included. Key words: Heteroptera, DAGs, MTGs, scent glands, bed bug Cimex lectularius, composition of secretion

Feeding ecology of freshwater Heteroptera (Nepomorpha)
Šretrová, Martina ; Sacherová, Veronika (advisor) ; Kment, Petr (referee)
This bachelor thesis focuses on the aquatic Nepomorpha living in freshwater, especially on the most common representatives from families, which we can find in the Czech Republic. The main theme of this work is the mapping of the feeding ecology of water-bugs. Various feeding strategies can be observed, such as phytophagy, carnivory and omnivory. The most important strategy used by most water-bugs is predation. This behavior is related to morphological adaptations, such as modifications of the mouthparts and forelegs. Ways of obtaining and processing prey are described in detail. A special chapter is dedicated to the Corixidae family, which differs morphologically. Also the importance of predatory water bugs in the ecosystem is discussed here.

Condition of dorsoabdominal scent glands in adults of the true bugs from the taxon Pentatomomorpha (Heteroptera)
Křížková, Petra ; Vilímová, Jitka (advisor) ; Kment, Petr (referee)
Existence of larval dorsoabdominal scent glands (DAGs) together with occurence of adult metathoracic scent glands is one of the important autapomorphic characters of taxon Heteroptera within taxon Insecta. DAGs can persist until adults in some species of this taxon. The persistence of DAGs were proved also in members of infraorder Pentatomomorpha. Targets of this thesis are: collect the knowledge about persistent adult DAGs in selected representative members of important families of taxon Pentatomomorpha; study and compare the condition of the DAGs in the oldest larval instars and adults; clarify the significance of existence the openings of conducting ductules of proper glandular units in reservoir intima of DAGs in study of the persistence of these glands. For study were used stereomicroscope, light and scanning electron microscope. Key words: Pentatomomorpha, Heteroptera, dorsoabdominal scent glands, openings of conducting ductules of glandular units, larvae of 5th instar, persistence in adults, persistence patterns, light microscope, scanning electron microscope

Condition of the larval scent glands in adults of the Heteroptera infraorders
Křížková, Petra ; Vilímová, Jitka (advisor) ; Kment, Petr (referee)
The Heteroptera scent glands system is formed by larval dorso-abdominal glands (= DAGs) and adult metathoracic glands ( = MTGs). The present study deals with a summary about occurrence of DAGs which are functional not only in larval but also in adult bugs, either proved or very likely. The part of general characteristics includes information about morphology, histology and functions of DAGs. The systematic review of published cases of DAGs' persitence in the adult stage represents the main part of the study. Recapitulations about possible positions of adult persistent DAGs and the characters used to prove gland functionality conclude the study. Based on the list of persistent adult DAGs, it is evident that they can be functional more often than was supposed. The DAGs functionality within heteropteran adults seems to be relatively widespread phenomenon, particularly in regards to a life in terestrial environment.

Ontogeny of dorsoabdominal scent gland complex in the representatives of the Pentatomoidea (Heteroptera).
Kutalová, Kateřina ; Vilímová, Jitka (advisor) ; Kment, Petr (referee)
Dorso-abdominal scent glands (= DAGs) of larvae represent one of apomorphic characters of insects order Heteroptera. These glands can persist until adults in different taxa. The persistence of DAGs were proved in the members of the family Acanthosomatidae. The ontogenetic development of DAGs cuticular structures were studied in all stadia, from 1st larval instar to adults of acanthosomatid Elasmucha ferrugata (Fabricius, 1787). The study concerned external structures and sculptures associated with DAG ostiole and areas of their surfaces, as well as internal structures, shape of gland reservoir and number of conducting ductules of proper glandular units. The light microscope and stereomicroscope and scanning electron microscope were used for this comprehensive study.

EU funds and their application in the frame of municipality's development
Majer, Luboš ; Kment, Petr (advisor) ; Lenka, Lenka (referee)
Summary
The aim of the final thesis is to realize whether the funds used from the EU are efficiently applied within the municipal development strategy, i.e. how capable is the Village of Malenice of using these funds effectively while implementing its projects. These projects are connected with the performance of the rural development programme which was approved by the council for the given periods.
The work includes two parts theoretical, practical and quantitative research of the given issue.
The first theoretical part introduces the origins of the regional policies within the EU, namely from the times when the European Economic Community was founded. It describes the 2007 2013 programming period in the Czech Republic, the current 2014 2020 programming period and the brief listing of the differences, including the list of projects implemented with the support of the EU funds in the Village of Malenice.
Second part focuses on the quantitative research which presents the method of semi-structured interviews with the village citizens. The interviews are completed with direct and indirect observation. The results of the research may help to further municipal development and may fulfill needs of the citizens in the new 2014 2020 programming period.

EU funds and their application in the strategy of municipality's development
Zajícová, Lucie ; Kment, Petr (advisor) ; Lenka, Lenka (referee)
The thesis deals with the use of European Union structural funds in the development of city Zatec. The theoretical part will focus on the basic concepts of regional policy and structural funds. First chapter of the practical part will be approximated on description of city Zatec and executed and planned projects. The most important project Temple of Hops and Beer which was built to enhance tourism in the region, is an important point of the practical part. The practical part of the work will also pay the processing and evaluation of secondary data, focused on demographic and social indicators and evaluation of statistical data traffic of Zatec tourists since the opening of the tourist object Temple of Hops and Beer. The main objective of this work will be an investigation in the form of an interview with the deputy mayor of the town of Zatec, regarding current and future projects financed from EU funds and their impact on the improvement of social and economic factors on life in the city. Subsequently conducted interviews with local residents of the city to determine their perception of the efforts the city council on the future development of the city.
