Molecular characterisation of three Ixodes (Pholeoixodes) species (Ixodida, Ixodidae) and the first record of Ixodes (Pholeoixodes) kaiseri from Slovakia

A study of ticks on wildlife was carried out in the area of Levice, Bratislava, Stupava, and Vrbovce (south-western Slovakia) during 2021 and 2022. Overall, 512 ticks were collected from 51 individuals of six wild mammalian species. Eight tick species were identified, namely Dermacentor reticulatus, D. marginatus, Haemaphysalis inermis, H. concinna, Ixodes ricinus, I. hexagonus, and two Ixodes spp. Ixodes hexagonus were collected from northern white-breasted hedgehogs (Erinaceus roumanicus), females belonging to Ixodes spp. were collected from red fox (Vulpes vulpes) and nymphs from European badger (Meles meles). Ixodes hexagonus and the Ixodes spp. were identified morphologically and molecularly based on sequences of fragments of two mitochondrial genes, COI and 16S rRNA. Molecular analysis of Ixodes spp. confirmed the identity of Ixodes kaiseri Arthur, 1957 and I. canisuga (Johnston, 1849). Sequence analyses show that the I. kaiseri isolate from Slovakia is identical to I. kaiseri isolates from Romania, Poland, Germany, Turkey, and Croatia. We demonstrate for the first time the presence of I. kaiseri in Slovakia using both morphological and molecular methods

The Factors Influencing Seasonal Dynamics and Spatial Distribution of Stable Fly Stomoxys calcitrans (Diptera, Muscidae) within Stables

The biology of the stable fly is fairly well known, but factors influencing the distribution of adult stable flies within stables are still inadequately investigated. The four experimental stables were located in south western Slovakia. Within each stable, five sticky traps were localized along the stable, and the flies were weekly counted during the flight season of years 2015–2017. Seasonal activity and stable fly abundance in relation to temperature, rainfall, light conditions, relative air humidity, and cows per stable were evaluated. The seasonal activity of the stable fly shows one large peak at the end of summer and a second smaller peak just before the end of the flight season. The spatial distribution of stable flies was unique for each stable. All of the environmental variables had significant and mostly positive effect on stable fly abundance. The strongest and most positive effect on stable fly counts was temperature and rainfall five weeks prior to collecting session. Within the stable, cow number, air humidity, and light conditions are the strongest candidates to influence their distribution
