ABSTRACT

The diversity and distribution of arthropods associated with seasons and environmental variables in two different wetlands sites was estimated and study was performed on monthly basis for a whole year. The arthropods were collected by sweep net, direct hand picking, forceps. For each sampling day in each month, 20 sweeps were randomly taken in each block. The insects at rest or on shrubs were manually collected. Overall, 5867 individuals were recorded pertaining to 152 species. Among the arthropods collected from two fields, number of the order Diptera was most diverse followed by those of Coleoptera, Hymenoptera, Hemiptera, Orthoptera, Lepidoptera, Araneae and Neuroptera. The number of arthropod species differed between localities and between the studied seasons. The arthropod composition varied significantly according to the sampled sites and according to the seasons studied. Temperature was positively correlated to diversity while humidity was negatively correlated to diversity and abundance. Results might be beneficial in developing the strategy for natural biological control. This can only be achieved by coordinated planning and conservation measures among sites.
