Biodiversity of aquatic insect and physicochemical water quality parameters in receiving
water bodies in Kasetsart University, Kamphaeng Saen Campus, Nakhon Pathom Province,
central Thailand were assessed during October 2010 to September 2011. Seven sampling stations,
each 100 m long, were established. Three replicates of samplings by aquatic D-net were used at
sampling sites. A total of 4,257 individual of aquatic insect were collected during one year. Six
Orders and 12 families were recorded in this study. The family Hydropsychidae and Chironomidae
were the most abundance of aquatic insects that found in receiving water bodies. The CCA
revealed the family Mesoveliidae and Chironomidae were correlated with alkalinity in receiving
water bodies, whereas dissolved oxygen was correlated with family Baetidae, Coenagrionidae,
Hydrophilidae, and Helotrephidae. Signs of increasing water quality deterioration were evident in
the result of the physicochemical analyses.
