“…rufipes is regularly introduced by migratory birds to Germany and other countries north of their natural distribution range (Hubálek et al 2020). Recently, it was hypothesized that adult H. rufipes might overwinter under local climatic conditions in Central Europe (Rudolf et al 2021). Adult ticks, especially, which infest horses and cattle have been found there.…”

An updated and increased compilation of georeferenced tick locations in Germany is presented here. This data collection extends the dataset published some years ago by another 1448 new tick locations, 900 locations of which were digitized from literature and 548 locations are published here for the first time. This means that a total of 3492 georeferenced tick locations is now available for Germany. The tick fauna of Germany includes two species of Argasidae in the genera Argas and Carios and 19 species of Ixodidae in the genera Dermacentor, Haemaphysalis, and Ixodes, altogether 21 tick species. In addition, three species of Ixodidae in the genera Hyalomma (each spring imported by migratory birds) and Rhipicephalus (occasionally imported by dogs returning from abroad with their owners) are included in the tick atlas. Of these, the georeferenced locations of 23 tick species are depicted in maps. The occurrence of the one remaining tick species, the recently described Ixodes inopinatus, is given at the level of the federal states. The most common and widespread tick species is Ixodes ricinus, with records in all 16 federal states. With the exception of Hamburg, Dermacentor reticulatus was also found in all federal states. The occurrence of the ixodid ticks Ixodes canisuga, Ixodes frontalis, Ixodes hexagonus and I. inopinatus were documented in at least 11 federal states each. The two mentioned argasid tick species were also documented in numerous federal states, the pigeon tick Argas reflexus in 11 and the bat tick Carios vespertilionis in seven federal states. The atlas of ticks in Germany and the underlying digital dataset in the supplement can be used to improve global tick maps or to study the effects of climate change and habitat alteration on the distribution of tick species.

“…However, during our program, both specimens of Hyalomma were discovered well after May, so these adults were presumably introduced the same year. Our tick monitoring program was not running during the spring, and there is a possibility for overwintering adultHyalomma in Hungary, as it has recently been shown in the Czech Republic (Rudolf et al, 2021). Unfed adult Hyalomma ticks tolerate the cold months well, with the most critical period being late summer and autumn due to the heat sensitivity of engorged nymphs (Uiterwijk et al, 2021;Valcárcel et al, 2020).…”

Hyalomma ticks are important vectors of Crimean-Congo Haemorrhagic Fever Virus (CCHFV) and other pathogens. They are frequently carried as immatures from Africa, the Middle East and Mediterranean areas to temperate Europe via migratory birds and emergence of its adults has been reported in many countries where it has so far been non-endemic. Our aim was to implement the first steps of the DAMA (Document, Assess, Monitor, Act) protocol by monitoring the potential arrival of adult Hyalomma ticks in Hungary applying citizen-science methods. Ticks were collected from April-December 2021 by asking volunteer participants through a self-made website to look for unusual hard ticks on themselves, their pets and livestock. Owing to the intensive media campaign, the project website had over 31 thousand visitors within seven months and 137 specimens and several hundreds of photos of hard ticks were submitted by citizen scientists from all over the country. Beside Ixodes ricinus, Dermacentor reticulatus,Dermacentor marginatus and Haemaphysalis inermis, a specimen from a dog was morphologically identified as a male Hyalomma marginatum and another removed from a cattle as a male Hyalomma rufipes. The dog and the cattle had never been abroad, they were approximately 280 km apart, thus the two Hyalomma observations can be considered as separate introductions. Amplification of the partial mitochondrial cytochrome C oxidase subunit I gene was successful for both specimens. Sequencing verified the previous morphological identification for both ticks. Based on the phylogenetic analyses the Hy. marginatum individual most likely belongs to the Eurasian population and the Hy. rufipes to a clade of mixed sequences from Europe and Africa. We summarize the scattered historical reports about the occurrence of Hyalomma ticks and CCHFV in Hungary. Our data highlight the effectiveness of citizens science programmes in the monitoring and risk assessment of CCHFV emergence and preparedness in our region.

Crimean-Congo haemorrhagic fever (CCHF) is the most widely distributed tick-borne viral disease in humans. The virus is widely expanded across western China, South Asia, and the Middle East to southeastern Europe and Africa. Its causative agent, Crimean-Congo haemorrhagic fever virus (CCHFV), is among the deadliest human pathogens in Africa and Eurasia. The historical known distribution of the CCHFV vector Hyalomma marginatum in Europe included most of the Mediterranean and the Balkan countries, Ukraine, and southern Russia. Further expansion of its potential distribution is possibly occurred in and out of the Mediterranean region. This study updated the map of the principal vector of CCHFV, H. marginatum, in the Old World. The model estimated the environmental suitability of H. marginatum in the Old World, including Europe. On the continental European scale, the model anticipated a widespread potential distribution, covering southern, western, central, and eastern Europe, as far north as southern parts of Scandinavian countries. The distribution of H. marginatum also covered the countries across the central part of Europe where the species is not autochthonous. All models were statistically robust and performed better than random (p < 0.001). Based on the results of the model, climatic conditions could hamper the successful overwintering of H. marginatum and their survival as adults in many areas of the region. Regular updates of the models, using updated occurrence, current, and future climatic data are recommended to regularly assess the areas at risk.
