GREGARINES (EUGREGARINORIDA, APICOMPLEXA) IN NATURAL-POPULATIONS OF DOCIOSTAURUS-MAROCCANUS, CALLIPTAMUS-ITALICUS AND OTHER ORTHOPTERA

Gregarina acridiorum Leger is redescribed based on material from Calli ptamus italicus and Dociostaurus maroccanus collected in Spain and in Locusta migratoria in Uzbekistan. This gregarine has a wide range of h osts and is broadly distributed in Palearctic region. Gregarina garnha mi Canning is considered to be a junior synonym of G. acridiorum. Inte nsity of parasitization in some host insects was very high which indic ates a detrimental effect on gut functions. Gregarine infections have been also recorded in the natural populations of the acridids Ailopus sp., Anacridium aegyptium, and Oedaleus decorus and of the tettigoniid Decticus albifrons collected on Iberian Peninsula and Canary Islands.
