A field experiment was conducted to evaluate the efficacy of certain newer insecticides against serpentine leaf miner, Liriomyza trifolii (Burgess) during summer 2019. Among the different chemicals (Abamectin 1.9 EC, 0.00057% Triazophos 40 EC, 0.05% Deltamethrin 2.8 EC, 0.0025% Emamectin benzoate 5 SC, 0.002% Imidacloprid 17.8 SL, 0.004% Cyantraniliprole 10.26 OD, 0.018% Cartap hydrochloride 50 SP, 0.075% the diamide insecticide cyantraniliprole registered the lowest number of leaf mines (4.34% and per cent damage on leaves (13.01% followed by abamectin and deltamethrin. This establishes the supremacy of diamide insecticides in the effective management of serpentine leaf miner on watermelon.
