Half (7) of the 14 most common mites collected in this study showed a marked preference for a single host species, which contradicts the hypothesis that nonparasitic mites are typically not host specific, at least locally.
The Seasonal Size Increase of Bumblebee Workers (Hymenoptera: Bombus)
Abstract Six field colonies and four laboratory colonies of bumblebees were used in a marking experiment during the summer of 1964 in Wisconsin to study the seasonal size increase of the workers.…

The known records of host – nasal mite species in Canada are expanded from 7 to 102, a 14-fold increase, and it is predicted that at least 70 species of rhinonyssid mites can be found in Canada.

In all but one species, U. orri, the data supported the existence of these host generalists, which contrasts with the typical finding that widespread generalists are actually complexes of cryptic specialists.

A new Paraleius species (Acari, Oribatida, Scheloribatidae) associated with bark beetles (Curculionidae, Scolytinae) in Canada

- 10 April 2017
Abstract Bark beetles (Scolytinae) are hosts to a broad diversity of mites (Acari), including several genera of Oribatida (Sarcoptiformes). Of these, Paraleius (Scheloribatidae) species are the most…
The natural history of mites (Acari: Mesostigmata) associated with the white-spotted sawyer beetle (Coleoptera: Cerambycidae): diversity, phenology, host attachment, and sex bias

There was no significant sex bias in the abundance or prevalence of mites between male and female M. scutellatus, which suggests that there is no selective advantage for mites to disperse on females.
Relative geographic range of sibling species of host damselflies does not reliably predict differential parasitism by water mites

The Arrenurus examined in this study appear to be ecological specialists, restricted to a particular type of habitat, parasitizing few to many of the host species present in that site or habitat.

It is conservatively estimated that nearly 10,000 species of mites occur in Canada, but the actual number could be 15,000 or more, which means that at least 70% of Canada’s mite fauna is yet unrecorded.
