The present experiment entitled Studies on efficacy of bio-rational insecticides against sucking pest of chilli was carried out in Insectary, Department of Entomology, CSAUA&T, Kanpur, U.P., during kharif 2018-19 to estimate the efficacy of bio-rational insecticides against major sucking pest, aphid (A. gossypi), thrips (S. dorsalis, and mite (P. latus) of chilli. Each treatment scheduled to observe the seasonal abundance and two sprays to evaluate the newer and bio-rational insecticides namely, pyproproxyfen 10% EC @ 0.5ml/l, imidacloprid 17.8 SL @ 0.25ml/l, neem oil 0.03% EC @ 5ml/l, novuluron+indoxocarb 5.25%+4.5% SC @ 0.2ml/l, verticilium 1.15%WP@ 5g/l, cypermethrin 25% EC @ 0.5ml/l, emamectin benzoate 5% SG @ 0.4ml/l, spinosad 45 SC @ 0.5ml/l. Pyproproxyfen 10% EC @ 0.5ml/l, imidacloprid 17.8 SL @ 0.25ml/l, novuluron+indoxocarb 5.25%+4.5% SC @ 0.2ml/l, and neem oil 0.03% EC @ 5ml/l were found to be most effective in controlling the aphids, thrips and mite population. Aphid population was effectively controlled by Pyproproxyfen 10% EC @ 0.5ml/l followed by, imidacloprid 17.8 SL @ 0.25ml/l, novuluron+indoxocarb 5.25%+4.5% SC @ 0.2ml/l. Thrips were significantly reduced by the novuluron+indoxocarb 5.25%+4.5% SC @ 0.2ml/l followed by imidacloprid 17.8 SL @ 0.25ml/l and neem oil 0.03% EC @ 5ml/l. The mite population was controlled by imidacloprid 17.8 SL @ 0.25ml/l followed by Pyproproxyfen 10% EC @ 0.5ml/l effectively.
