Survey of nasal mites (Rhinonyssidae, Ereynetidae, and Turbinoptidae) associated with birds in Alberta and Manitoba, Canada

  • Wayne Knee (a1), Heather Proctor (a2) and Terry Galloway (a3)


Three major lineages of mites (Arachnida: Acari) are parasitic in the nasal passages of birds: Rhinonyssidae (Mesostigmata), Ereynetidae (Prostigmata), Cytoditidae, and Turbinoptidae (Astigmata). The most diverse group of avian nasal mites is the Rhinonyssidae, which are obligate endoparasites of non-ratite birds worldwide. Prior to this study, there were only four published and three unpublished records of nasal mites from birds in Canada. In Alberta, 15% of 450 birds (154 species) examined during 2003–2007 were infested with nasal mites; in Manitoba, 16% of 2447 birds (196 species) examined during 1996–2006 were infested. We have expanded the known records of host – nasal mite species in Canada from 7 to 102, a 14-fold increase. There are now 50 species of Rhinonyssidae, 7 species of Ereynetidae, and 1 species of Turbinoptidae known from birds in Alberta and Manitoba. We predict that at least 70 species of rhinonyssid mites can be found in Canada.

Trois lignées principales d’acariens (Arachnides: Acari) sont parasites dans les passages nasaux des oiseaux: Rhinonyssidae (Mesostigmata), Ereynetidae (Prostigmata), Cytoditidae et Turbinoptidae (Astigmata). Le groupe le plus diversifié d’acariens nasaux aviaires sont les Rhinonyssidae, qui sont des endoparasites obligatoires des oiseaux autres que ratites dans le monde entier. Avant cette étude, il y avait seulement quatre mentions publiées ainsi que trois cas non publiés d’acariens nasaux des oiseaux au Canada. En Alberta, 15 % de 450 oiseaux (154 espèces) examinés entre 2003 et 2007 étaient infestés avec des acariens nasaux; au Manitoba, 16 % de 2447 oiseaux (196 espèces) examinés entre 1996 et 2006 étaient infestés. Cette étude fait passer la liste des mentions d’acariens nasaux sur un hôte aviaire au Canada de sept à 102, soit une augmentation de l’ordre de 14 fois. Il y a maintenant 50 espèces de Rhinonyssidae, 7 espèces d’Ereynetidae, et 1 espèce de Turbinoptidae connues associées aux oiseaux en Alberta et au Manitoba. Nous prévoyons qu’au moins 70 espèces d’acariens rhinonyssides peuvent être trouvées au Canada.
