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

Indukce autogenie biologicky aktivními látkami u druhu \kur{Culex quinquefasciatus Say}
ŠEFČÍK, David
The main aim of this study was determinate which factors could induce autogeny and compare differences between autogenous and anautogenous populations of mosquitoes. All experiments were done with \kur{Culex quinquefasciatus Say}. Effects on temperature and food on the inductuion of autogeny were studied. Autogenous females usually don´t have to receive a blood during the first ovarian cycle. Our results confirmed that autogeny can be induced by temperature and different food high nutritive level.

Differences of autogeny and anautogeny population of mosquitoes Culex pipiens quinquefasciatus Say
DIVOKÁ, Petra
The aim of submited Thesis was to contribute to illustration on differences in development of female genital organs in autogeny and anautogeny population of mosquito Culex pipiens quinquefasciatus Say. Currently, a consequence of ekdyson agonists was tested for change evoked in the development and fertility this species. Gained results showed that in anautogeny population is process of vitellogenesis depended on blood- feeding. In autogeny population, there is no need to blood- fed during the first gonotrophic cycle. Tested compound indicated vitellogenesis in a sublethal doses then egg-laying was followed. In comparison with that, application of higher doses showed sterilisation effect. Gained results show this compound useful for regulation of mosquitoes population, especially in the area of disease transmitted by them.
