Co-parasitism of mites of the superfamily Trombidioidea (Actinotrichida: Parasitengona) – a host-specificity-related phenomenon?
Hanna Moniuszko , Joanna Mąkol
AbstractThe problem of co-parasitism is closely associated with recognition of inter- and intraspecific variation of parasites and their site preferences which result in occupation of different niches. Narrow and highly specific niches may result from the history of acute competition among parasite species or may be due to the lack of competition associated with the absence of niche overlap. Trombidioidea, one of the three superfamilies of terrestrial Parasitengona, are represented by ca. 4000 nominal species. Larvae of members of most of the families (13) are obligatory parasites of arthropods; two families are associated with vertebrates and the host spectrum of one (Yurebillidae) remains unknown. Co-parasitism is rare among the arthropod-associated Parasitengona. The phenomenon has been confirmed for ca. 3% of cases of invasion. The cohabitation is accompanied by distinct divergence of site preferences. Several cases of co-parasitism have been observed in vertebrate-associated families (Trombiculidae, incl. Leuwenhoekiidae, and Walchiidae). However, the actual frequency of this phenomenon remains unknown. It can be due to various factors, among which unrecognized interspecific variation can play a crucial role. During our studies on bat- and rodent-associated trombiculids, cases of co-invasion were observed for three host species. The co-parasitic mites belonged to the same or different genera, which was confirmed by morphological and molecular analyses. The present study aims at finding the possible evolutionary background for co-parasitism, with special reference to vertebrate-associated trombiculids.
