title: [Experimental studies on Gregarina ovata Dufour, 1828: macro and microsporocysts, parasitic specificity, lasting of the life cycle (author's transl)].
abstract: The present study based mostly on experimental infestations deals with three questions related to Gregarina ovata, an Eugregarine parasite of Dermaptera: a) Gregarina ovata does not provide two patterns of sporocysts (macro and micro) as it has been thought until now. Through the experimentation, two species can be determined only by their mature gametocysts and sporocysts; b) The host specificity is not strict. Two species or even two genus of Dermaptera can be parasitized by the same Gregarine; c) The life-cycle, from ingested sporocysts to new sporocysts, is from 13 to 16 days for Gragarina ovata (species with large sporocysts) and from 11 to 13 days for Gregarian fallax (species with small sporocysts.
