Abstract
Fresh water ecosystems are colonized by a diverse array of aquatic organisms and often contribute the bulk of regional freshwater biodiversity. Aquatic insects are abundant in most freshwater habitats and often exhibit high diversity and play an important role in ecosystem functioning by virtue of their abundance, taxonomic diversity and trophic significance besides, water quality monitoring as reliable indicators. Ponds are an excellent habitat for biodiversity studies of freshwater insects. The present paper focuses on the diversity of hemipteran fauna in Sengunam pond, Perambalur, Tiruchirappalli, Tamil Nadu, India. The hemipteran insects recorded from Sengunam lake were Aquarius and Limnogonus (water striders), Nepa (water scorpion), Ranatra (water scorpion/water stick insect), Hesperocorixa and Corixa (water boatman), Notonecta (backswimmer), Neoplea and Paraplea (pygmy backswimmers), Lethocerus (giant water bug) and Diplonychus (water bug). Therefore, it is imperative to make continuous investigation, census and research activities on the taxonomy and diversity of aquatic insects, so that knowledge regarding this important group can be utilized by future researchers as baseline data for further research and conservation planning of both the aquatic insects and water bodies.
