This paper investigated the dominant species of insect communities in five stored export products along Yangtze River in Jiangsu Province. With the indexes species richness, ecological dominance, community diversity and evenness, the numerical characteristics of insect community structure in the stored products were analyzed, and the similarity of the communities was also analyzed. By the method of hierarchical cluster analysis, the numerical classification was made, and the communities were grouped into 4 groups. The insect communities in stored willow and feather products were in the same group, while those in other stored products were grouped into 3 groups. Except that in woodwork products, the insect community structures in other stored products, especially in leather products, were not rational.
