Recent data on Demodex rosus Bukva, Vitovec et Vlcek, 1985 (Acari, Demodecidae) from oral cavity of yellow-necked field mouse, Apodemus flavicollis (Rodentia, Muridae)

Until now, Demodex rosus has been only recorded in the Czech Republic; however, as many as 81 specimens of this species have been observed in 7 yellow-necked field mice collected from Gdansk Pomerania, Poland (prevalence 35%, mean intensity 11.6). This is the first observation of that species in Poland. In Polish fauna, Apodemus flavicollis proved to be a new host of mites belonging to Demodecidae. All specimens of D. rosus have been found in the mouse oral cavity
