Aquatic insect population in irrigated rice fields of Coimbatore was studied during early Samba and late Thaladi on 2018-2019. The collected aquatic insects represented six insect orders, Hemiptera, Coleoptera, Diptera, Odonata, Collembola and Ephemeraptera. Application of butachlor @ 1.25 kg/ha on 35 DAT reduced the aquatic faunal abundance especially the Hemiptera and Collembola. Application of cartap hydrochloride @ 50 SP 400g/acre on 65 days after transplanting resulted in increased population abundance of Hemipter while the remaining faunal population abundance was drastically reduced especially Collembola which failed to survive after the application of the insecticide.
