The occurrence and harm of stored grain pests in flour processing sites are unavoidable, and the habits of different pests are different. It is of great significance to know the types of pests and the characteristics of their occurrence in flour mills to avoid or reduce the losses caused by pests in flour processing sites. Investigated in the low-temperature and high-humidity grain storage area (the third area), the middle-temperature dry grain storage area (the fourth area), the middle-temperature high-humidity grain storage area (the fifth area) , High temperature and high humidity food storage area (the seventh area) a total of five grain storage ecological zone, involving the eight provinces 43 flour enterprises in the insect species and fauna. The survey results showed that there were 93 insect species occurring in flour processing sites, involving Insecta and Arachnida, 10 orders and 37 families. 21 families of Coleoptera involving insects, 6 families of Lepidoptera, 2 families of cockroach and Hymenoptera, each of 1 species of Cichlid, Hymenoptera, Hemiptera, Coccinella and Diptera Section, arachnoid Scorpio head a branch.
