Belostomatidae commonly called as giant water bug belongs to the infraorder Nepomorpha. Thirumalai (2007) recorded three species of the genus Diplonychus from India. These predatory insects feed on aquatic crustaceans, fishes, amphibians and mosquito larvae. The results of Saha (2007) reveal that a single adult of D. rusticus could consume 11-87 fourth instar larvae of Culex quinquefasciatus Say per day and D. annulatus consume 33-122 fourth instar larvae per day, depending upon the prey and predator densities.
