Benthic Insect Abundance and Distribution in A Polluted Pond

Habeeba A. Kabeer, Saltanat Parveen

Abstract :

The present work aims to analyze benthic insect abundance and species composition in a polluted pond. Sediment and water samples were collected monthly over one year–cycle (2009–2010). The distribution and abundance of benthic insects was affected by a number of ways. Multivariate statistical analysis of data was done to calculate the effect of environmental variables on benthic insect distribution during different months. Canonical correspondence analysis were plotted which clearly detected physicochemical factors (water temperature, conductivity, total dissolved solids, conductivity, organic carbon, organic matter, etc.) relation with benthic insects. Along–this pond variation of the benthic insect with climatic factors was well assessed, Ephemeroptera was highly affected by composition of clay, organic matter, total solids, water temperature and nitrate concentration whereas Hemiptera showed high positive correlation with calcium and dissolved oxygen. Diptera is one of the most dominating group among all another groups. Presence of high abundance of Chironomus larvae showed polluted condition of this pond.
