Autogeny by phlebotomine sandflies
Pavlasová, Michaela ; Votýpka, Jan (advisor) ; Sádlová, Jovana (referee)
1 Abstract In haematophagous insect autogeny means an eggs development and ability to set first egg batch without previous blood-feeding on a host. Autogeny developed in several groups of invertebrates mainly order Diptera and more rarely orders Heteroptera and Acari. It occurs mostly as an alternative possibility of development in case of unsuitable conditions or absence of hosts. This thesis includes present findings about autogeny among subfamily Phlebotominae and families Culicidae, Simuliidae, Ceratopogonidae and Tabanidae. The thesis focuses on factors influencing autogeny such as nutrition during larval development, geographic and genetic factors, temperature and photoperiodic aspects. The thesis is targeted mostly on sandflies, important vectors of many pathogens, and on influence of autogeny on its vectorial potential. Key words: autogeny, ovarian development, Phlebotomus, Culicidae, Simuliidae, Ceratopogonidae, Tabanidae

Diverzita mikrobiomů vybraných druhů ovádů (Diptera: Tabanidae) a její vliv na přenos trypanosom \kur{(Trypanosoma sp.)}
SVOBODOVÁ, Simona
Three different bacterial symbionts have been known from blood-sucking horse flies (Tabanidae), Spiroplasma from family Spiroplasmaceae, Midichloria from family Midichloriaceae and Wolbachia from family Rickettsiaceae. Microbiomes of tabanids has been explored only marginally, therefore in my thesis I explore them in more details. I have described microbiomes of 7 species from Africa, USA and Czech republic, and found them to contain bacteria from families Spiroplasmataceae, Chthoniobacterales, Pseudomonadaceae, Acetobacteraceae, Enterobacteriaceae, Flavobacteriaceae, Staphylococcaceae, Halomonadaceae, Moraxellaceae. In addition, I have studied Trypanosoma´s influence on the compositon to the horse fly microbiome. I have not found significant differences between microbiomes of infected and uninfected individuals, indicating that the presence of Trypanosoma may not have any strong effect on the microbiome.
