RESUMO
Objective To investigate the breeding quantity and average breeding density of Gohieria fuscus in the grand dust flour of a flourmill and explore the prevention and control measures. Methods A certain amount of grand dust flour was collect-ed from a flourmill,and it was sieved. The powder was placed into the glass pan,and the mites were sought out under an optical microscope and made of specimens. The mites were identified on the basis of literature. Results In this survey,400 g samples were collected from 4 habitats. The average breeding density of mites was 3516/g. The mite was identified as Gohieria fuscus. Conclusions Gohieria fuscus is one of the widely distributed stored mites. It impacts the stored food and reduces the quality of food. In addition,the mite affects human health. Therefore,the preventive measures should be taken.
