| Abstract | ||||
| The present study was conducted during two years (2015 and 2016) to throw light on the acari fauna of some common stored hay in different regions covered 7 Egyptian governorates differed in their ecological conditions. This study revealed the occurrence of 32 mite species differed in their feeding behavior infested different stored hay materials, belonging to 27 genera and 16 families under four suborders as follows:Suborder Astigmatawhich represented by 8 species belong to 7 genera and 3 families. The recorded families were Acaridae (5 species), Glycyphagidae (2 species) and Pyroglyphidae (one species). Also, suborder Prostigmata represented in this study by 14 mite species belonging to 12 genera in 7 families. The families were Cunaxidae (2 species), Eupodidae, Scutacaridae, Bdellidae and Tarsonemidae (one species for each), Cheyletidae (4 species) and Tydeidae (4 species). On the other hand, the mesostigmatid mites represented by 9 mite species belonging to 7 genera in 5 families were recorded. The dominant mite species was Proctolaelaps pygmaeus (Ascidae) and the most collected families were Ascidae and Laelapidae (3 species for each), while the cryptostigmatids haveonly one species in this study, Siculobata sicula (Berlese) belonging to Oribatidae. The most frequent and most dominant mites in this study were: Tyrophagus putrescentiae, Tarsonmeus graneries and Proctolaelaps pygmaeus as fungivorous mites; Caloglyphus berlesi and Acarus siro as grnaviorous mites; Pronematus rykei, Cheyletus eruditus, C. malaccensis and Blattisocius keegani as predators mainly on acarid mites and other microarthropds stored product pests. The study indicated that wheat and broad bean were the most stored hay containing mite species, 5 and 4 mites, respectively, but rice, soybean and barley hay were infested with only two mite species. On the other hand, the clover hay was contained three mite species. The study also showed that, Ashmoun region represented the highest number of mite species (32), while, El-Wahat El-Baharia and Kom Oshim regions were the lowest regions contained only (6) mite species. | ||||
