Abstract
The study deals with population diversity and multivariate analysis of insects and spiders of Sandspit mangrove forest dominated by grey mangrove Avicennia marina. In order to get informations about the seasonal variations and the distribution of insects and arachnids of Sandspit mangrove forest monthly data was collected from 2007 to 2008. A total of 33 species of insects and arachnids were recorded. Among them 28 species associated with class insecta; most of the species belong to orders Diptera. Only six species of spiders were recorded from the study area belonging to five families. Few insects are biting type causing irritation and pain to the human being; however they live frequently in the mangrove forests. Species diversity (H') of class insecta species is 604.1 while species richness and evenness were .0400 and 7.02 respectively. Species diversity (H’), Species richness, evenness and dominance of Arachnida species are60060, .07.0, 60.0. and .001. respectively. The Dendrogram resulting from Ward s clustering strategy shows no clear cut grouping due to chaining effect of taxa. The pattern of species on the ordination axes were disclose on monthly basis.
