The pomegranate aphid, Aphis punicae (Passerini) (Homoptera: Aphididae) is one of the most important pestsin Karnataka on pomegranate tree. The study presented in this paper was conducted during 2020 to compare the efûcacyand selectivity of chemical insecticides (imidacloprid 17.8 SL, flonicamid 50 WG, acetamiprid 20 SP, thiamethoxam 25 WG,clothianidin 50 WDG and fipronil 5 SC) against A. punicae. The results revealed that the selected insecticides were effectivein reducing the aphids population over untreated control. Among the different insecticides tested, highest per cent reductionof 87.48% was recorded in imidacloprid 17.8 SL followed by flonicamid 50 WG (85.00%), acetamiprid 20 SP (80.52%) andthiamethoxam 25 WG (78.86%).
