In order to provide an scientific basis and technology support to local agricultural by–products export quarantine, an investigation was carried out on the species of stored insects of export agricultural by–products from 2003 to 2005 in the region. The quarantine significance of different stored insects and the insect community structure characteristics of five stored export products were analyzed, besides, a study was conducted on the ecology of Dermestes maculatus Degeer in the laboratory. The main results were as follows. 1. The ordinary and systematic measures were used to investigate stored insect species on export products, such as Willow, Brush, Feather, Leather, Woodwork, grain, coconut funicle, lotus leaf etc., in the finished product, transferring, material reserve and processing storages of the export industries.
