| Abstract: |
| A faunistic survey of Astigmatid mites associated with stored grains products was conducted in 14 provinces of Iran during 1996-2014. About 2,500 samples of different types of grains and their derivatives were taken from silos, flour mills and mills. The materials sampled included wheat, rice, paddy, maize, barn, barley, chaff, dust, broken wheat, broken rice and brass scarp. Samples were extracted by modified Berlese faunal and mite species prepared in Hoyer medium on slides and identified. During the survey, 9 families, 15 geneses and 20 species were found and over 60% of the samples contained mites. Tree species were found to be dominant in all sampled materials and locations infested by mites: Tyrophagus putrescentiae (Schrank), Acarus siro L. and Lepidoglyphus destructor (Schrank). T. putrescentiae was the most common species and recorded in all types of materials. A. siro and L. destructor occurred in 81% of different sampling materials. Three provinces had the highest species diversity of mites: Golestan (70%), Mazandaran (65%) and Gilan (40%). The diversity of mite species was higher in wheat than in other materials. In wheat 16 species, in dust 10 species, and broken wheat and brass scarp 9 species were identified. |
