Abstract: Objective To investigate the composition and density of acaroid mites breeding in stored products of rural areas in Anhui province. Methods Acaroid mites were isolated by Waterflotation and Tullgren, and counted and identified under XTB microscope. Results 31 species of acaroid mites were isolated from 40 different stored products(700 samples), which were identified to 20 genera of 7 families. Acaroid mites can be checked out from each sample above all. The highest density (332.67±7.85)No./g was found in seasame, while the lowest was (13.43±5.28)No./g in hot peppers. In addition, Tyrophagus putrescentiae was most widely distributed and was found in 23 different stored products. Conclusion Many species of acaroid mites breeding in stored products are widely distributed and are seriously harm to stored products, so effective measures should be taken for control.
