Sarcophagides (Diptera) parasites de Porthetria dispar (L.) en Sardaigne et leur cartographie dans le réseau U. T. M.

Eight species of Sarcophagan dipterans we obtained from laboratory
cultures ofPorthetria dispar(L.), a defoliator of cork oak forests in Sardinia.
Of these species:
-Parasarcophaga exuberansPand. andParasarcophaga portschinskyiRohd. are new to the italian fauna;
-Parasarcophaga tibialisMacq.,Parasarcophaga tuberosaPand.,Parasarcophaga uliginosaKram. andPseudosarcophaga affinisFall. are new
to the sardinian fauna;
-Parasarcophaga exuberansPand.,Parasarcophaga miseraWalk.,Parasarcophaga tuberosaPand. andThyrsocnema corsicanaVill. are described
as being entomophagous for the first time.P. disparis previously unrecorded as a host ofParasarcophaga tibialisMacq., while forParasarcophaga uliginosaKram. this host has been hitherto
unrecorded in Europe.
Biogeographical data for these species were analysed in terms of their
spatio-temporal dinamics, using a 10 km x 10 km grid U. T. M. map of
Sardinia for reference.
Using the metodology of the international project of theEuropean
Invertebrate Survey, (chairman: Prof. Dr. JEAN LECLERCQ, Gemblaux-Belgium),
U. T. M. code Jists of aIl Sardinian towns were compiled.
