摘要：This paper represented a preliminary three months data on the aquatic insect diversity of two ponds, one private property pond and one community pond of Irongmara village, district Cachar, Assam. The communitypond (pond1) was characterized by market and household waste disposal site and the privatepond (pond2) was characterized by a community fishery. A total of 16 families belonging to 5orders from pond 1 and 9 families belonging to 4 orders from pond 2 were recorded. The insect order Diptera was found to be abundant and dominant in pond1, while in pond2 the order Hemiptera was found more abundant and dominant. Dissolved oxygen of water on pond1 was found very low with high Free-CO2 and Electrical Conductivity while in pond2 the dissolved oxygen was found in good concentration with low Free-CO2 and Electrical Conductivity. Different biomonitoring scores were computed to see the water quality of the ponds and statistical analyses were done to find the relationship of environmental variables with insect density and family richness. The present study compared the water quality of the two types of ponds and concluded that the authorities, management and users should come forward with protective measures to save the ponds from deterioration.
