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

Haemoproteus in passerines: infection dynamics at the individual level
Chalupová, Barbora ; Svobodová, Milena (advisor) ; Hořák, David (referee)
The genus Haemoproteus is worldwide distributed parasitic protist, which belongs to the phylum Apicomplexa. This blood parasite has dixenous life cycle and he is occurs in the bird's blood and in invertebrate vectors. Genus Haemoproteus is transmitted by blood-sucking vectors, biting midges (Ceratopogonidae) and hippoboscid flies (Hippoboscidae). Vectors are final hosts of the genus Haemoproteus and the sexual process takes place in these vectors. Birds are intermediate hosts, in which representatives of the genus Haemoproteus spend most of their lives. In this bachelor thesis I focused on the influence of the genus Haemoproteus on birds and I focus on the time, when the bird gets infected by Haemoproteus in his life. Key words: Haemoproteus, birds, infection, life cycle, host, Ceratopogonidae, Hippoboscidae
