Efficacy of insecticides against citrus leaf miner, Phyllocnistis citrella Stainton (Gracillariidae: Lepidoptera) in acid lime (Citrus aurantifolia)

Abstract

The citrus leaf miner (Phyllocnistis citrella) Stainton is one of the key pests of acid lime. A field experiment on the efficacy of selected new molecules of insecticides against citrus leaf miner revealed that two applications of spinosad 45 SC (0.30 ml/l) and flonicamid 50 WG (0.30 g/l) were significantly effective. Other insecticides viz., thiamethoxam 25 WG (0.25 g/l), emamectin benzoate 5SG (0.40 g/l) and chlorantraniliprole 18.5 SC (0.10 ml/l) were found moderately effective in control of the pest. The imidacloprid 70 WG (0.30 g/l) and fipronil 5 SC (1.00 ml/l) were found to be least effective against citrus leaf miner. The effective insecticides can be used in scheduling for control of citrus leaf miner on acid lime.
