“…On the other hand P. herfsi occurred only in spring at all locations, but A. tribolii occurred mainly in summer. The aforementioned results were in agreement with the findings of Wafa et al (1966b) and Mahmood (1992) who found that the population density of Melicharis sp. and Cheyletus sp.…”

“…The obtained data indicated that the most common mite pests (D. farinae and A. siro) were abundant mainly during autumn and winter in both mixed flour and grain residues. Similar results were found by Wafa et al (1966b) and Mahmood (1992) who mentioned that some acarid mite species such as Tyrophagus sp. occurred mainly during autumn and winter.…”

Twenty one mite species belonging to 3 suborders and 11 families were found in grain residues and mixed flour samples collected from warehouses and mills at Great Cairo. They were 12 pest species, 7 predatory and 2 parasitic species. Species commonly found in all inspected materials at all locations were Dermatophagoides farinae Hughes, Tyrophagous putrescentiae (Sch.) and Cheyletus malaccensis Oud. However Acrus siro (Lin), Acarophenax tribolii (New.) and Pyemotes herfsi (Oud.) were often abundant. The remaining species occurred sporadically in the collected materials. Actinedid and acaridid mites were "dominant" and "constant" in mixed flour and grain residues samples, the second group was the most abundant. Whereas gamasid mites was "recedent" and "accidental". Mixed flour taken from Qaliobia Governorate harboured the highest number of mite species (15 species) followed by grain residues from Giza Governorate (13 species). While grain residues taken from Cairo Governorate harboured the lowest number (5 species).The highest infestation level with mites (2677.3 individuals) was recorded in mixed flour at Qaliobia Governorate, while the lowest one (1067 individuals) was found in grain residues at Cairo Governorate. Generally, mixed flour harboured more mite species than grain residues. Most of the collected mite species occurred during autumn and winter except P. herfsi and A. tribolii which were recorded during spring and summer, respectively. Dominance and frequency of occurrence, population fluctuations, effect of temperature and relative humidity on the population dynamics, also the relation between the predators and pests of mites were discussed in details.

“…In previous surveys Franz et al (1997) in Germany recorded 49 taxa, Long-shu and Qing-Hai (1997) in China 79 taxa, Mahmood (1992) in Iraq 16 taxa, Corpuz-Raros et al (1988) in Philippines 65 taxa, Saleh et al (1985) in Egypt 33 taxa, Pagliarini (1979) in Croatia 23 taxa, Cusack et al (1975) in Ireland 70 taxa, Zdarkova (1967, 1998) in former Czechoslovakia 41 and 32 taxa, respectively, and O'Farrell and Butler (1948 in Northern Ireland recorded 62 taxa. In Greece, in earlier surveys of a more limited geographical extent, Emmanouel et al (1994) recorded 17 taxa, Palyvos et al (2002) 37 taxa, andPapaioannou-Souliotis (1991) found 28 taxa of mites in house dust.…”

“…Studies intended to record the mites infesting stored agricultural products have been conducted in several regions throughout the world (O'Farrell and Butler 1948;Zdarkova 1967Zdarkova , 1979Zdarkova , 1998Cusack et al 1975;JeVrey 1976;Pagliarini 1979;Saleh et al 1985;Corpuz-Raros et al 1988;Mahmood 1992;Emmanouel et al 1994;Franz et al 1997;Long-shu and Qing-Hai 1997;Thind and Clarke 2001;Stejskal et al 2003;Kucerova and Horak 2004;Hubert et al 2006). Although some general trends can be seen, data from one study may not be comparable with others and generalizations are often problematic.…”

Mites associated with stored products in Greece

2008

A faunistic survey of mites was conducted in many product stores during a 6-year study period, 2000-2005, 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), flour, bran, manufactured agricultural foodstuffs, dried fruits (figs, raisins), residues and dust, stored in varying quantities in five types of storage facilities (stores of agricultural cooperative unions, farm stores, commercial stores, flour mills and silos). Dominance-frequency analysis and redundancy analysis (RDA) were used to reveal the preferences of the collected taxa. Approximately 55% of the samples contained mites and 65 mite taxa were identified, belonging to 15 families in four orders. Six species, namely, Acarus gracilis Hughes, A. immobilis Griffiths, 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 first 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.

“…Mite pests are cosmopolitan and have been reported from many parts of the world (Mahmood 1992;Haines 1997;Hubert et al 2003Hubert et al , 2006Kucerova and Horak 2004;Collins 2006;Mahmood et al 2012). Rhizoglyphus tritici Bashir, Afzal, Honey and Khan (Acari: Acaridae) is abundant in stored grain in the Punjab Province of Pakistan (Bashir et al 2011).…”
