Objective To investigate the breeding status of acaroid mites in the stored grains in Dalian areas, Liaoning province. Methods The acaroid mites were isolated from different stored grains and identified by microscopy directly or by electric separation method. Results Twelve species of mites were identified from 5 categories of grains. These mites belong to 4 families and 10 genera, including Acarus siro, Acarus farris, Tyrophagus Putrescentiae, Tyrolichus casei, Caloglyphus berlesei, Rhizoglyphus callae, Suidasia nesbitti, Lardoglyphus konoi, Lepidoglyphus destructor, Lepidoglyphus michaeli, Austroglycyphagus geniculatus and Dermatophagoides farinae.
