Repelentní účinky silic vybraných rostlinných druhů
Mašláňová, Hana
The summer season is accompanied by an increased incidence of diptera in livestock farming. The insect is a vector of many diseases and in high frequencies reduce milk and meat production. Significant economic losses in cattle breeding are mainly caused by cosmopolitan synanthropic and synbovine species Musca domestica, Stomoxys calcitrans and Haematobia irritatans. An alternative way of controlling insects without negative affecting health and the environment is the application of the herbal preparations containing repellent essential oils. Formulated mixture of essential oils Mentha x piperita, Pelargonium sp. and Nepeta cataria and essential oils Cymbopogon citratus, Cymbopogon nardus and Eucalyptus globulus were able to repel insects for 6 hours with 87% and 73% efficacy on cattle.

The influence of height above ground on colonization of carcasses by blow flies (Calliphoridae)
Mudrochová, Michaela ; Barták, Miroslav (advisor) ; Olekšáková, Tereza (referee)
The forensic entomology is a special discipline of criminology which uses knowledge about insects cycles, mainly Diptera and Coeloptera, to determine the post-mortem interval. The post-mortem interval is time from death to finding of a corpse.
In the Czech Republic, there wasn´t implemented any terraneous experiment that would prove the truth or disprove about the influence of height above ground on colonization of carcasses by blow flies (Calliphoridae). Experimental part was directly focused on that. For the experiment, there was used a building with six floors, precisely it was used balconies on the third and sixth floors and bush at the ground level in the shadow in front of the building. Meat baits which represented cadavers were on the all floors. Baits were used for colonization and breeding species of flies which were determined afterwards. Finally, obtained data were evaluated for their utilization in forensic entomology.

Family Muscidae on large cadavers with the beginning of decomposition in the winter and its use in forensic practice
Dočekalová, Tereza ; Barták, Miroslav (advisor) ; Klimešová, Vanda (referee)
Forensic entomology is a one of the special fields of criminology. That uses knowledge of biology, ecology and especially insects and other invertebrates, which occur on cadavers or in its vicinity. These and other arthropods are used as circumstantial evidences during the investigation and also verify other evidence in civil and criminal law.
This bachelor thesis deals with the use of Diptera of forensic practice with focusing
on family Muscidae by form of a scientific work. The first part of the thesis is focuses
on history and current use of forensic entomology, advances in characterization of thematic cases in which the family Muscidae was used as well as describes main species of the family. The second part describes the field experiment in which the presence of the family Muscidae on model organism (pig carrion) was studied and its use in forensic practice.
