A field experiment was conducted to evaluate the efficacy of certain selective insecticides against the serpentine leaf miner Liriomyza trifolii (Burgess) in water melon Citrullus lanatus (Thunb.) Matsum and Nakai. The hybrid F1 (Melody) was sown in protray and 13 days old seedlings were transplanted in the main field. Significant less live mines (1.48/leaf) was observed with chlorantraniliprole 18.5%SC @0.6 ml/l. This was followed by flubendiamide 39.35%SC @0.6 ml/l (2.09/leaf) and indoxacarb 14.5%SC @0.65 ml/l (3.05/leaf). Leaf damage/plot was 2.72, 3.48 and 4.03%, with chlorantraniliprole, flubendiamide and indoxacarb, respectively. Significantly maximum yield of fruits (25.5 t/ha) was obtained with chlorantraniliprole given as three sprays at 15 days interval. Thus, chlorantraniliprole 18.5%SC @0.6 ml/l can be recommended against L. trifolii in water melon.
