The experiment was carried out on roof at Entomology Department of Bangladesh Jute Research Institute (BJRI), Dhaka for the selection of dosages and in the field of two different locations viz. Jute Agriculture Experimental Station (JAES), Manikganj and Jute Research Sub-Station, Tarabo, Narayanganj for evaluation of four insecticides against jute hairy caterpillar during the jute growing season (April-July) 2019 following Randomized Complete Block Design (RCBD) with three replications. Heping 10WDG (Emamectin Benzoate), Lamtech 2.5 EC (Lambda cyhalothrin), Fair Kill 10 EC (Cypermethrin) and Key 70 WG (Imidacloprid 70 %) @ 750 gm/ha, 200 ml/ha, 550 ml/ha and 30 gm/ha respectively were found effective against jute hairy caterpillar giving 86.13, 81.51, 74.11, 76.39 percent reduction of infestation in Manikganj and 86.21, 82.32, 77.53, 78.64 percent reduction of infestation in Narayanganj respectively. In case of yield contributing characters at both locations, Heping 10WDG (Emamectin Benzoate), Lamtech 2.5 EC (Lambda cyhalothrin), Fair Kill 10 EC (Cypermethrin) and Key 70 WG (Imidacloprid 70 %) were found effective significantly giving more than plant height (2.87m), base diameter (14mm), fibre weight (2.82 t/ha) and stick weight (6.12 t/ha) respectively. Percent Reduction, plant height, base diameter, fibre weight and stick weight were found highest in the plot treated with Heping 10WDG (Emamectin Benzoate) and the lowest was found in control plot. All tested insecticides can be recommended for controlling jute hairy caterpillar and in respect of higher yield contributing characters.
