Abstract:

To understand the structure of insect community and insight into its inner connections, we classified insect communities in Taihu Wetland into different groups based on their taxonomic status and analyzed the relationships of niches between the groups in this study. The results showed that the spatial niche breadth, temporal niche breadth and temporal-spatial niche breadth were obviously different between different groups, indicating the groups fully utilized resources in Taihu Wetland. Among these groups, Hemiptera community had the widest temporal-spatial niche breadth, reflecting Hemiptera insects had the widest distribution and longest activity period; By contrast Dermaptera community had the narrowest temporal-spatial niche breadth, showing Dermaptera insects needed strict habitats and had relatively narrow distribution. Diptera and Coleoptera had relatively large spatial-temporal niche overlap value, which indicated that they had similar unitization of resource and a predator-prey or competitive relationship could be existed between the two groups in Taihu Wetland.

Key words: insect community, niche, Taihu Wetland
