note = "In recent years the production of wild truffles has
dropped alarmingly, and at the moment not even the
establishment of a large number of trees plantations of
the gender Quercus mycorrhizal whith this fungus have
achieved that date back production. Moreover we find that
the quality is seriously influenced by the presence of
arthropod parasites. Not much information is had of the
major diseases which affect the truffle or how to control
it. In this research we have studied arthropod populations
present in the most economically important species in Spain
different samples of summer truffle (Tuber aestivum), black
truffle (Tuber melanosporum) and Tuber brumale, in order to
identify and assess the degree of parasitism of the species
they affect. 5 different species have been found: Leiodes
cinnamomea, Ommatoilus sabulosus, Megaselia sp, Lycoriella
sp and Helomyza tuberivora. Of these last 3 it has been
managed to reproduce their entire life cycle of Tuber and
Pleurotus ostreatus. Ommatoilus sabulosus, Megaselia sp.
and Lycoriella. are new records in terms of parasitism
associated with sporocarps of the gender Tuber. The
dipterans Megaselia sp, Lycoriella Sp. and Helomyza
tuberivora are pests that cause severe losses in the
product quality, but they also help the fungus to spread
its spores, along with they are indicators of its presence
in the truffle tree burning. The presence of Ommatoiulus
sabulosusis associated as a secondary pest, because that
parasitizes T. melanosporum when it is mature, using
pre-built galleries formerly made by- other parasites,
causing serious drillings that devalue economically and the
quality of-the product. It has been found that, unlike
other published studies in relation to Leiodes cinnamomea
beetle, larvae are parasites of both, T. aestivum and T.
melanosporum. This is a difference with adults witch only
appear in T. melanosporum, causing both (larvae and adult)
severe damage to the fruiting bodies. The results obtained
are intended to bring some light to the parasitism
associated with the gender Tuber fruiting bodies to
establish in future studies, possible strategies of
controlling these arthropods in the truffle, thus avoiding
losses in both economic and in the so appreciated quality
of the product.",
