Saitanis Received: 28 October 2007 / Accepted: 20 March 2008 / Published online: 1 April 2008 Springer Science+Business Media B.V. 2008 Abstract A faunistic survey of mites was conducted in many product stores during a 6-year study period, 20002005, in Greece. A total of 1,073 samples were taken from 34 Greek counties. The survey was carried out on grains (wheat, maize, oat, barley), X our, bran, manufactured agricultural foodstu V s, dried fruits ( W gs, raisins), residues and dust, stored in varying quantities in W ve types of storage facilities (stores of agricultural coopera- tive unions, farm stores, commercial stores, X our mills and silos). Dominance-frequency analysis and redundancy analysis (RDA) were used to reveal the preferences of the col- lected taxa. Approximately 55% of the samples contained mites and 65 mite taxa were identi W ed, belonging to 15 families in four orders. Six species, namely, Acarus gracilis Hughes, A. immobilis Gri Y ths, Caloglyphus oudemansi (Zachvatkin), Suidasia medanensis Oudemans, Tyrophagus perniciosus Zachvatkin and Kleemania plumigera (Oudemans), were new to the fauna of Greece. Five species, Tyrophagus similis Volgin, Blattisocius mali (Oudemans), Neoseiulus barkeri (Hughes), Cheyletus cacahuamilpensis Baker and Storchia robustus (Berlese), were recorded for the W rst time in stored products in Greece. Lepidoglyphus destructor (Schrank), Tyrophagus putrescentiae (Schrank) and Acarus siro L. were dominant or intermediate in all storage facilities examined. Cheyletus malaccensis Oudemans was the most common predatory mite. The highest percentage of infestation (65.3) was recorded in the samples from stores of agricultural cooperative unions. Residue- type materials had the highest degrees and percentages of infestation. Keywords Stored-product mites Grains Storage facilities Dominance Frequency RDA Dust Residue N. E. Palyvos ( & ) N. G.

It is well documented that insects (Coleoptera, Lepidoptera and Psocoptera) and mites are the most damaging pests associated with stored grains. The degree of a products infestation depends on the pests involved, the environmental conditions (e.g. temperature and moisture content), how the product is stored and the degree of proper hygiene conditions. The type of storage technology applied is considered a serious abiotic factor in X uencing the stored-grain...
