  abstract = {{W}heat represents a principal ingredient in traditional {T}unisian diet including couscous, bread, pasta and biscuits. {N}orthen {T}unisia is an important growing area of wheat which after harvest is stored in silos and on farm. {T}he cereal grains can become contaminated by post-harvest moulds during storage in silos under unfavorable conditions leading to a decrease in quality, packing and marketing of wheat. {I}n this study, a mycological survey was undertaken to determine the biodiversity of post-harvest moulds on durum wheat stored in silos localized in five regions of {N}orthern {T}unisia and to investigate changes during the storage period. {A} total of 127 samples were obtained from {O}ued {M}liz, {J}endouba, {K}sar {M}ezouar, {M}ateur and {G}hezala silos during 2010-2011 and 2011-2012 wheat seasons. {A}fter sampling, seeds were placed on {P}otato {D}extrose {A}gar medium ({PDA}) for 7 days of incubation at 28 degrees {C}. {A} total of 6035 strains of filamentous fungi were isolated. {T}he quantitative and qualitative changes on wheat mycoflora during storage were statistically explored by multivariate methods including correspondence and hierarchical cluster analysis. {T}he most predominant post-harvest moulds genera isolated were {A}lternaria (28%), {F}usarium (19%), {P}enicillium (19%), {A}spergillus (14%), {M}ucor (8%) and {R}hizopus (7%). {V}arious genera of fungi imperfecti, including {U}locladium, {G}eotrichum, {C}haetomium, {T}richothecium, {P}aecilomyces, {A}ureobasidium and {C}hrysonilia (anamorphic {N}eurospora), and the {M}ucorales genera {L}ichtheiia and {S}yncephalastrum accounted for the remainder of about 6% of the total. {S}tatistical data analysis revealed six mycological patterns corresponding to six distinct communities as characterized by the prevalence of different moulds. {S}uch patterns clearly showed different spatio-temporal variability indicating that distribution and evolution of moulds during storage was sensitive to geographic location, year of sampling and short or long-term storage.},
