[Identification of mosquito-parasitic microsporidia, Amblyospora rugosa and Trichoctosporea pygopellita (Microsporidia: Amblysporidae), from Acanthocyclops venustus and Acanthocyclops reductus (Copepoda: Cyclopidae), based on small subunit rDNA analysis].

Identical small subunit rDNA sequences were obtained for microsporidia Amblyospora rugosa from blood-sucking mosquitoes larvae Ochlerotatus cantans, O. cataphylla and copepods Acanthocyclops venustus, as well as for Trichoctosporea pygopellita from mosquitoes larvae Ochlerotatus cyprius, O. excrucians and copepods Acanthocyclops reductus. The data on molecular phylogeny and ecological researches show that in Siberia mosquito-parasitic microsporidia of the genera Amblyospora and Trichoctosporea have complex life cycle involving likely intermediate hosts, Acanthocyclops copepods. Life cycle of parasites is synchronized with phenology of their hosts. The phylogenetic analyses shows, that genus Trichoctosporea should be transferred from the family Thelohaniidae to the family Amblyosporidae.
