title: [Insect diversity of different habitat types in Zhalong Wetland, northeast China].
abstract: In order to approach the effects of different habitat types in wetland on insect diversity, an investigation was conducted on the insects in eight types of habitats in Zhalong Wetland. A total of 5822 insects were collected, belonging to 143 species, 58 families, and 11 orders, among which, Orthoptera, Dipteral and Odonata were the dominant taxa. The species diversity was the highest in grassland meadow, and the Shannon diversity index and evenness index were higher in lakeside but the lowest in wet meadow. Cluster analysis and principal component analysis showed that the similarity of the insect community in the habitats was related to the water source status and vegetation type, and the species and individual number of predatory taxa had important regulation effects on the insect community stability. Lakeside had the strongest insect community stability, while wet meadow had the weakest one, indicating that habitat water source status could affect insect survival, and further, affect the species composition and distribution pattern of insect community.
