Taxonomy, life cycles and the origin of parasitism in trombiculid mites

  • Andrey B. Shatrov

Concluding remarks

The ontogenetic threshold related to the large size difference between heteromorphic larva and post-larva has inevitably led to larval parasitism and regression of nymphal instars in trombiculid mites. It is most likely that mammals are primary hosts of trombiculid larvae, whereas the use of other terrestrial vertebrates as hosts arose later. An association with a host takes only a short time from the entire life cycle of a trombiculid mite; a mite spends the rest of its life as a free-living soil-dweller. As a result, host selection by a trombiculid larva is determined mainly by habitat distribution of a host rather than by its taxonomic affinity.
