On the basis of 3 years observation the author differentiates these 6 forms of dermatologic simuliosis: edematous form, erythematous-edematous, so-called erysipeloid form, inflammatory-indurative, so-called phlegmonoid form, haemorrhagic plaques, numerous haemorrhagic nodules, haemorrhagic vesicles. According to the analysis of the year 1983, the painful edematous and haemorrhagic forms occur most frequently.

The effect of the suspension of Bacillus thuringiensis var. israelensis spores on larvae of the blackfly Odagmia ornata was studied in the laboratory and under field conditions of a natural biotope in southern Bohemia. The preparation Moskitur was used and its effect was tested in laboratory at temperatures 0.1-2.9 degrees C and 17-19 degrees C. Although O. ornata larvae were able to filter feed on a lethal dose of the preparation even at a lower temperature than 2.9 degrees C, no marked manifestation of mortality was observed at low temperatures in comparison with a control sample.

During the years 1999-2002, a total of 4,898 individuals of 26 species of hematophagous insects (4,149 mosquitoes, 583 black flies, and 166 tabanid flies) was examined for the presence of spirochetes using dark-field microscopy. There was an overall recovery of spirochetes from the midguts of Culicidae and Simuliidae of 23.5% and 11.4%, respectively. Spirochetes were not detected in Tabanidae. Seven spirochetal strains have been successfully recovered from mosquitoes and black flies: BR149 (Culex pipiens), BR151 (Cx. pipiens), BR173 (Cx. pipiens), BR177 (Cx. pipiens), BR193 (Aedes cinereus), BR208 (Cx. pipiens), and BR231 (Simulium noelleri). The strains have been adapted to laboratory conditions (BSK-H Complete medium). Their preliminary determination based on 16S rRNA gene sequencing has shown that they differ from the Lyme disease spirochete Borrelia burgdorferi sensu lato as well as other members of the Order Spirochaetales indicating novel bacterial species in the Family Spirochaetaceae.

Trypanosomes are known as widespread blood parasites of birds; however, knowledge of their prevalences in vectors and their overall biodiversity is rather limited. To assess the prevalences in potential vectors, we have microscopically examined ornithophilic bloodsucking Diptera (Culicidae, Simuliidae and Hippoboscidae) for the presence of trypanosomatids in their guts. In total, 3270 specimens were dissected, namely Culex pipiens Linnaeus, 1758 (n = 898), C. modestus Ficalbi, 1890 (136), Simulium vernum (Macquart, 1838) (1455), S. angustipes Edwards, 1915 (221) and Ornithomyia avicularia (Linnaeus, 1758) (560). All insect species were found to be infected with trypanosomatids, and the prevalence ranged from 4 to 8% but reached 60% in S. vernum. Blackflies and hippoboscids exclusively harboured trypanosomes (both T. cf. avium s.s. Danilewsky, 1885; T. corvi/culicavium group in hippoboscids). Mosquitoes were infected with T. culicavium Votypka, 2012 and T. avium s. l. but also with monoxenous parasites, namely Crithidia brevicula Frolov and Malysheva, 1989, and Paratrypanosoma confusum Votypka and Lukes, 2013. Only 4% of the isolated parasite strains were monoxenous whereas the majority were avian trypanosomes, confirming the vectorial status of the studied insects.

The section of habitat used by particular bloodsucking insects when seeking bloodmeals may influence the spectrum of hosts to which they have access and consequently the diseases they transmit. The vertical distribution of ornithophilic bloodsucking Diptera (Culicidae, Simuliidae and Ceratopogonidae) was studied using bird-baited traps set at both ground and tree canopy levels. In total, 1240 mosquito females of eight species, 1201 biting midge females of 11 species, and 218 blackfly females of two species were captured during 2003-2005. Culex pipiens (L.) (Diptera: Culicidae) was found to prefer ground-level habitats, whereas Anopheles plumbeus (Stephens) (Diptera: Culicidae), biting midges [Culicoides spp. (Diptera: Ceratopogonidae)] and Eusimulium angustipes (Edwards) (Diptera: Simuliidae) preferred the canopy. The results of this study with regard to Cx. pipiens behaviour differ from those of most previous studies and may indicate different spatial feeding preferences in geographically separate populations. The occurrence of E. angustipes in the canopy is concordant with its role in the transmission of avian trypanosomes. These findings may be important for surveillance programmes focusing on ornithophilic Diptera which transmit various pathogenic agents.
